Quick answer
Ideal body weight is generally calculated using the body mass index (BMI): body weight (kg) divided by the square of height (m). A BMI of 18.5 to 25.0 is considered normal in adults according to the Indonesian Ministry of Health classification, while the Broca formula provides a quick estimate. The result is only an initial guide because BMI does not distinguish between muscle and fat. Body weight is maintained through a balanced diet, regular exercise, and periodic monitoring.
An ideal body weight is not only important for your appearance, but also plays a major role in maintaining heart health. This article explains how to calculate your ideal body weight based on your height and what your BMI value means for your health.
Many people wonder whether their body weight is within a healthy range. That is why how to calculate ideal body weight is one of the most frequently searched health topics. Quite a few people use the number on the scale as a measure of health. In reality, however, assessing ideal body weight is not as simple as looking at your weight alone.
Body weight is indeed often associated with appearance. However, in medicine, ideal body weight is far more important as an indicator of the body’s health. When your weight is outside the healthy range, whether too high or too low, your body has to work harder to carry out its vital functions. The heart, blood vessels, and metabolic system may come under additional strain, which ultimately increases the risk of health problems.
In fact, various international health organizations emphasize that overweight and obesity are closely linked to an increased risk of chronic diseases. These conditions may increase the likelihood of:
- Heart and blood vessel disease
- Type 2 diabetes
- Hypertension (high blood pressure)
- Other metabolic disorders
On the other hand, a body weight that is too low does not always indicate good health either. In some cases, it may be related to nutritional deficiencies, metabolic disorders, or certain diseases. That is why understanding how to calculate ideal body weight is an important first step in evaluating your health objectively.
One of the methods most often used by health professionals to assess body weight is the body mass index, or BMI. This method calculates the ratio between body weight and height to estimate whether a person falls into the underweight, normal, overweight, or obese category. According to the World Health Organization (WHO), BMI is a simple and widely used screening tool for assessing weight status in the adult population.
Besides BMI, there are several other approaches commonly used to determine ideal body weight, such as the Broca formula, which provides a simple estimate based on a person’s height.
That is why, in this article, you will learn several important things about how to calculate ideal body weight, including:
- How to calculate ideal body weight using easy-to-understand methods
- The body mass index (BMI) formula and how to use it
- Alternative methods such as the Broca formula
- How to interpret the results to understand your health
By understanding this concept, you will not only know your ideal weight number, but also see the bigger picture of how body weight affects heart health, metabolism, and overall quality of life.
Next, before learning the calculation methods, it is important to first understand what ideal body weight actually means.
What Is Meant by Ideal Body Weight?
Before learning how to calculate ideal body weight, it is important to first understand what the term means. In general, ideal body weight is the weight range considered healthiest for the body based on a person’s height and physical characteristics. So, ideal body weight is not a single absolute number, but a range that helps the body carry out its vital functions optimally.
Indeed, many people think ideal body weight is only about appearance. However, from a medical perspective, ideal body weight is more closely related to long-term health. When your weight is within a healthy range, the body’s organs, including the heart, blood vessels, and metabolic system, can work more efficiently.
Health professionals usually use several indicators to assess whether a person’s weight is within a healthy range, one of which is the body mass index (BMI). This method helps estimate whether a person’s weight is classed as underweight, normal, overweight, or obese based on their height.
By understanding this concept first, learning how to calculate ideal body weight becomes easier and more meaningful.
Factors That Affect Ideal Body Weight
Everyone’s body is different. That is why the ideal weight range is also influenced by several important biological factors.
First, height
Height is the main factor in determining a healthy weight range. The taller a person is, the more body mass is needed to support the bone structure and body tissues.
Second, sex
Men and women naturally differ in body composition. Generally, men have more muscle mass, while women physiologically have a slightly higher percentage of body fat.
Third, body composition
Not all body weight comes from fat. The human body is made up of various components, such as muscle, bone, body fluids, and other tissues. That is why two people with the same weight can have different health conditions depending on their body composition.
Fourth, age
As you age, your metabolism may slow down and muscle mass tends to decrease. These changes may affect fat distribution as well as overall body weight.
Because of these various factors, ideal body weight is usually calculated using an approach based on body ratios, such as the body mass index, to give an initial picture of a person’s weight status.
The Difference Between Ideal Body Weight, Normal Body Weight, and Healthy Body Weight
In everyday conversation, the terms ideal body weight, normal body weight, and healthy body weight are often considered the same. In fact, the three have slightly different meanings.
Ideal body weight
Refers to an estimated weight range considered most suitable for a person’s height and body structure, based on a particular calculation method.
Normal body weight
Usually refers to the weight category within the normal BMI range, which is 18.5 to 25.0 in adults according to the Indonesian Ministry of Health (Kemenkes) classification.
Healthy body weight
This term has a broader meaning. It considers not only the number on the scale, but also overall health, such as blood pressure, blood sugar levels, cholesterol levels, and fitness level.
In other words, a person may have a normal body weight but not necessarily be in a truly healthy metabolic condition.
The Link Between Ideal Body Weight and Heart Health
Maintaining an ideal body weight is not just about the number on the scale. In fact, body weight has a major influence on heart health and the metabolic system.
Excess body weight can increase the risk of various cardiovascular diseases, including coronary heart disease, high blood pressure, and type 2 diabetes.
Conversely, when your weight is within a healthy range, your body tends to be better able to:
- Keep blood pressure stable
- Regulate blood sugar levels better
- Reduce the heart’s workload
- Lower the risk of metabolic disorders
That is why understanding how to calculate ideal body weight not only helps you know your current condition, but is also a first step toward maintaining heart and metabolic health in the long term.

Why Is Knowing Your Ideal Body Weight Important?
Knowing your ideal body weight is not just about appearance. More than that, this number is one of the important indicators for assessing overall health, especially the health of the heart and blood vessels. That is why doctors often use various methods, such as the body mass index (BMI) or the ratio of height to weight, to help assess whether a person is within a healthy weight range.
In fact, an unbalanced body weight, whether too high or too low, can increase the risk of various chronic diseases. Therefore, understanding and monitoring your ideal body weight is an important first step in preventing cardiovascular disease and maintaining long-term quality of life.
1. Body Weight as an Indicator of General Health
Body weight often reflects the balance between energy intake and the body’s needs. When the body takes in more energy than it uses, the excess is stored as fat. Conversely, if energy intake is too low, the body may lose muscle mass as well as important energy reserves.
That is why knowing your ideal body weight helps give an initial picture of your body’s metabolic condition. In fact, many health professionals use body weight as part of initial screening to assess the risk of diseases such as metabolic disorders, heart disease, or diabetes.
In addition, body weight is also closely related to various other health factors, from blood pressure and cholesterol levels to blood sugar levels. In other words, keeping your weight within a healthy range may help the body work more efficiently and reduce the strain on vital organs, including the heart.
2. Health Risks If Body Weight Is Too High
When body weight exceeds the ideal range, the body has to work harder to carry out its normal functions. This condition can trigger various health problems, especially those related to the cardiovascular system.
Overweight or obesity is one of the major risk factors for heart disease. Some of the health risks that may arise include:
- Obesity: excess fat buildup in the body can trigger chronic inflammation and metabolic disorders.
- Heart and blood vessel disease: excess body weight increases the risk of coronary heart disease, heart failure, and even stroke.
- Type 2 diabetes: excess body fat can cause insulin resistance, making blood sugar levels harder to control.
- High blood pressure (hypertension): increased body weight can make the heart work harder to pump blood, which ultimately raises blood pressure.
Therefore, keeping your weight within a healthy range is an important part of a strategy for preventing heart disease early.
3. Risks If Body Weight Is Too Low
On the other hand, a body weight that is too low should not be taken lightly either. The body needs sufficient energy reserves, nutrients, and muscle mass to carry out various vital functions.
A person whose weight is below the normal range may experience various health problems, such as:
- Deficiencies in essential nutrients, including protein, vitamins, and minerals
- Reduced immunity, making the body more susceptible to infections
- Muscle weakness and prolonged fatigue
- Hormonal and metabolic disorders
In the long term, this condition may also affect bone health, the immune system, and overall quality of life.
4. Benefits of Knowing Your Ideal Body Weight
Knowing your ideal body weight offers many practical benefits for everyday health. It not only helps you understand your current condition, but also serves as a guide for maintaining a healthy lifestyle in a sustainable way.
Some of its main benefits include:
- Helps monitor your health: changes in body weight can be an early signal of certain health problems.
- Serves as a basis for planning your diet or exercise: by knowing a healthy target weight, nutrition and physical activity programs can be designed more appropriately.
- Supports a healthy lifestyle in the long term: a balanced body weight helps maintain heart function, metabolism, and daily energy.
Ultimately, understanding ideal body weight is not just about the number on the scale. Rather, it is a simple yet important step in maintaining overall health, especially in efforts to prevent heart disease early.
So, after understanding why it is important to know your ideal body weight, the next question is: how do you calculate it accurately?
In the next section, we will discuss several simple methods commonly used to calculate ideal body weight in practice.
How to Calculate Ideal Body Weight
Understanding how to calculate ideal body weight is an important step in finding out whether your weight is within a healthy range. However, it should be understood that no single method is completely perfect for determining the ideal body weight for everyone. The human body is influenced by many factors, from muscle composition, fat distribution, age, and sex to physical activity level.
That is why medical professionals usually use several methods as an initial guide, not as a final diagnosis. The two most commonly used approaches are:
- BMI (body mass index)
- The Broca formula
Both methods help give an initial picture of a healthy weight range.
Doctors can then consider other factors such as waist circumference, body fat composition, and overall health.
How to Calculate Ideal Body Weight Using BMI
What Is BMI, or Body Mass Index?
Body mass index (BMI) is the most commonly used method worldwide to assess whether a person’s weight is classed as underweight, normal, or excessive. This method compares body weight with height to produce an index number.
In fact, various global health organizations use BMI as an initial screening tool to assess the risk of weight-related diseases, including heart disease and diabetes. For example, the World Health Organization and the American Heart Association use BMI as a population indicator for assessing obesity risk.
The BMI Formula
The BMI formula is quite simple:
BMI = body weight (kg) / height² (m)
This means body weight divided by the square of height in meters.
How to Calculate BMI Step by Step
To make it easier to understand, here are the steps for calculating BMI:
Example:
- Body weight: 70 kg
- Height: 170 cm
Calculation steps:
- Convert height to meters: 170 cm → 1.70 m
- Square the height: 1.70 × 1.70 = 2.89
- Divide body weight by that result: 70 ÷ 2.89 = 24.2
So, this person’s BMI is about 24.2.
BMI Categories According to Health Standards
Below are the BMI categories for adults according to the Indonesian Ministry of Health classification, which is the one used in Indonesia.
| Category | BMI value |
|---|---|
| Underweight | < 18.5 |
| Normal | 18.5 to 25.0 |
| Overweight | > 25.0 to 27.0 |
| Obesity | > 27.0 |
What each category means:
- Underweight (<18.5): Body weight is below the healthy range. This condition may be related to a lack of nutrition or muscle mass.
- Normal (18.5 to 25.0): This range is generally considered healthy for most adults.
- Overweight (> 25.0 to 27.0): Body weight is starting to exceed the ideal range and may increase the risk of metabolic disorders.
- Obesity (> 27.0): A condition of excess fat buildup that is linked to an increased risk of chronic diseases such as heart disease, hypertension, and diabetes.
That is why many doctors use BMI as a first step to identify cardiovascular disease risk early.
How to Calculate Ideal Body Weight Using the Broca Formula
What Is the Broca Formula?
Besides BMI, another method often used to estimate ideal body weight is the Broca formula. This method was introduced by French surgeon Paul Broca in the 19th century as a simple way to estimate ideal body weight based on height.
Unlike BMI, which produces an index, the Broca formula directly estimates an ideal body weight figure.
This method is popular because it is easy to calculate without special tools.
The Broca Formula
The Broca formula calculation differs slightly between men and women.
For men:
Ideal body weight = (height − 100) − 10%
For women:
Ideal body weight = (height − 100) − 15%
Example Calculations Using the Broca Formula
Example for a man
Height: 170 cm
Calculation steps:
- 170 − 100 = 70
- 10% of 70 = 7
- 70 − 7 = 63 kg
So, the ideal body weight according to the Broca formula is about 63 kg.
Example for a woman
Height: 160 cm
Calculation steps:
- 160 − 100 = 60
- 15% of 60 = 9
- 60 − 9 = 51 kg
So, the ideal body weight according to the Broca formula is about 51 kg.
Advantages and Limitations of the Broca Formula
Advantages:
- The calculation is very simple
- Easy to calculate without a calculator
- Suitable as a quick estimate
Limitations:
However, the Broca formula also has several limitations. This method does not take body composition into account, such as muscle mass, fat distribution, or differences in body shape between individuals.
For example, a person with a lot of muscle mass, such as an athlete, may appear to have a higher body weight according to this formula, even though their body is healthy.
Interpreting the Results Wisely
Both BMI and the Broca formula can help you understand how to calculate ideal body weight in a simple way. However, the results should be seen as an initial guide, not an absolute health assessment.
In medical practice, doctors usually also consider other factors, such as:
- Waist circumference
- Body fat composition
- Medical history
- Diet and physical activity
With this more comprehensive approach, the risk of disease, especially heart and metabolic disease, can be assessed more accurately.
Next, to make this calculation easier to understand in everyday life, let’s look at examples of ideal body weight calculations based on height in various situations.
Examples of Ideal Body Weight Calculations Based on Height
Many people search for information such as “ideal weight for a height of 160 cm” or “ideal weight for a height of 170 cm”. These questions are very common because height is indeed one of the main factors in determining ideal body weight.
In practice, ideal body weight is usually estimated using the body mass index (BMI). This method is widely used by health organizations around the world because it helps assess the balance between body weight and height as an initial indicator of health.
A BMI range of 18.5 to 25.0 is classified as normal weight for adults according to the Indonesian Ministry of Health classification. Based on this range, we can estimate the ideal weight range by height, as shown in the following table.
Table of Estimated Ideal Body Weight by Height
| Height | Estimated ideal body weight |
|---|---|
| 150 cm | ± 42 to 56 kg |
| 155 cm | ± 44 to 60 kg |
| 160 cm | ± 47 to 64 kg |
| 165 cm | ± 50 to 68 kg |
| 170 cm | ± 53 to 72 kg |
| 175 cm | ± 57 to 77 kg |
The table above gives a simple overview of the ideal weight range based on height. For example:
- If your height is 160 cm, your ideal body weight range is usually around 47 to 64 kg.
- If your height is 170 cm, the healthy weight range is generally around 53 to 72 kg.
This calculation comes from the following BMI formula:
BMI = Body Weight (kg) ÷ (Height in Meters)²
As a simple illustration:
- A height of 160 cm (1.6 m) with a BMI of 18.5 → about 47 kg
- A height of 160 cm with a BMI of 25.0 → about 64 kg
In other words, the numbers in the table are weight ranges that statistically still fall into the normal or healthy category.
Why Can Ideal Body Weight Differ From Person to Person?
Although the table is often used to answer questions such as “what is the ideal weight for a height of 160 cm?”, it is important to understand that these numbers are not exact values.
Indeed, BMI gives a fairly good picture for the general population. However, ideal body weight can still vary between individuals. Some of the factors that affect it include:
- Body composition (muscle mass vs. body fat)
- Sex
- Age
- Body fat distribution
- Certain health conditions
For example, a person with high muscle mass, such as an athlete, may weigh more than the table shows but still be healthy. Conversely, a person with a normal weight according to BMI does not necessarily have an optimal body composition.
In fact, BMI is only an initial screening tool, not a comprehensive health diagnosis.
Use the Table Above as an Initial Guide
So, the table of ideal body weight by height should be used as an initial guide to understanding your body.
However, a more accurate health evaluation usually requires additional assessments, such as:
- Waist circumference
- Body fat percentage
- Blood pressure
- Blood sugar and cholesterol levels
- Personal and family medical history
In addition, consulting a medical professional can also help determine the target weight most suitable for your body.
So, after understanding examples of ideal body weight calculations based on height, it is also important to look at a common follow-up question: is BMI always accurate in determining ideal body weight? This question will be discussed in the next section.
Is BMI Always Accurate in Determining Ideal Body Weight?
Body mass index (BMI) is often used to estimate ideal body weight. This method calculates the ratio between body weight and height to group a person into the underweight, normal, overweight, or obese category.
Indeed, because the calculation is simple, BMI is widely used in public health practice in many countries. Health organizations such as the World Health Organization (WHO) and the Indonesian Ministry of Health also use BMI as an initial screening tool to assess weight-related health risks.
However, it is important to understand that BMI is not always accurate in determining an individual’s ideal body weight. A BMI number can give a general picture, but it does not fully reflect the body’s overall condition.
Limitations of BMI in Assessing Ideal Body Weight
BMI uses only two simple parameters: height and body weight. That is why this method cannot describe a person’s body composition in detail.
Some important aspects that BMI does not take into account include:
- Muscle mass: BMI does not distinguish between weight that comes from muscle and weight that comes from fat. Yet muscle tissue is denser than fat.
- Body fat composition: Two people with the same BMI value can have very different body fat percentages.
- Fat distribution in the body: Where fat builds up also plays an important role. Fat in the abdominal area (visceral fat) is known to be more closely linked to an increased risk of heart and metabolic disease than fat in other areas.
In addition, factors such as age, sex, and the body’s metabolic condition can also affect how BMI is interpreted. That is why health experts emphasize that BMI should be seen as an initial indicator, not a final health assessment.
Why Can Athletes Have a High BMI but Still Be Healthy?
An example often used to explain the limitations of BMI is athletes or individuals with high muscle mass.
As an illustration:
- A weightlifter may have a relatively high body weight because of their large muscle mass.
- If calculated using BMI, their value may fall into the overweight category.
- In reality, however, the athlete may have a low body fat percentage, good cardiovascular fitness, and a healthy metabolism.
This shows that a BMI number does not always accurately reflect body composition. Therefore, BMI has limitations, especially in certain groups such as athletes, older adults, or individuals with different body compositions.
BMI Is Still Useful, but It Is Not the Only Health Assessment
Despite its limitations, BMI remains a useful initial indicator for assessing weight status. In fact, this method is still widely used in health screening because it helps identify potential risks of diseases such as type 2 diabetes, hypertension, and heart disease.
However, doctors usually do not rely on BMI alone. To understand a person’s body more accurately, health assessments usually also include several additional indicators, such as:
- Waist circumference to assess visceral fat buildup
- Body fat percentage
- Blood pressure
- Blood sugar and cholesterol levels
- Personal and family medical history
This more comprehensive approach helps ensure that the assessment of ideal body weight is based not only on the BMI number, but also takes overall health into account.
That is why understanding the limitations of BMI in determining ideal body weight is an important step before making decisions about a healthy lifestyle. The next, more practical question is: how can you keep your weight ideal in everyday life? The next section will discuss strategies that may help you achieve this in a healthy and sustainable way.
How to Maintain an Ideal Body Weight
Knowing how to calculate ideal body weight is an important first step in understanding your body. However, keeping your weight within a healthy range requires consistent daily habits.
A stable body weight is not just about appearance. In fact, maintaining an ideal body weight may help lower the risk of various chronic diseases, such as heart disease, type 2 diabetes, high blood pressure, and metabolic disorders. That is why, besides understanding how to calculate it, it is also important to apply strategies that help the body maintain its energy balance sustainably.
In general, an ideal body weight can be maintained through three main steps: eating a balanced diet, exercising regularly, and monitoring your weight periodically.
1. Follow a Balanced Diet
First, maintaining an ideal body weight starts with a balanced and controlled diet. This means the body gets enough nutrients without excess calories.
A healthy diet should include various food groups in balanced portions. In addition, calorie intake also needs to be adjusted to a person’s daily energy needs.
Some simple principles you can apply include:
- Eat more vegetables and fruit: vegetables and fruit are rich in fiber, vitamins, and antioxidants that help support the body’s metabolism and keep you feeling full longer.
- Choose complex carbohydrate sources: for example, brown rice, oatmeal, or whole wheat bread. These carbohydrates are digested more slowly, which helps keep blood sugar levels more stable.
- Get enough protein: protein from fish, eggs, legumes, or lean meat helps maintain muscle mass while also increasing satiety.
- Limit foods high in sugar, salt, and saturated fat: Ultra-processed foods and sugary drinks are often high in calories but low in nutrients.
Besides choosing the right types of food, controlling portion sizes is also very important. Portions that match your needs help the body maintain its energy balance so that your weight stays within the ideal range.
2. Be Physically Active Regularly
Besides diet, regular physical activity also plays a major role in keeping body weight stable.
When the body moves, the calories taken in from food are used as a source of energy. As a result, it is easier for the body to maintain a healthy weight.
Adults are advised to get at least 150 minutes of moderate-intensity physical activity every week.
Some types of physical activity you can do include:
- Brisk walking
- Cycling
- Swimming
- Exercise classes or fitness training
Besides structured exercise, everyday physical activity is also important. For example, walking more often, taking the stairs instead of the elevator, or doing household chores.
With this combination of activities, the body can burn calories more effectively, helping you maintain the results of the ideal body weight calculation you did earlier.
3. Monitor Your Weight Regularly
Next, it is important to monitor your weight regularly. This habit helps you know whether your weight is still within a healthy range or is starting to change.
In addition, monitoring your weight also helps you evaluate whether your diet and physical activity are working.
If the result of your ideal body weight calculation shows a fairly large gap from your current weight, lifestyle improvements can be started earlier.
Maintaining an Ideal Body Weight Is a Long-Term Process
Ultimately, maintaining an ideal body weight is not about reaching a certain number in a short time. Rather, it is a long-term process that requires consistency.
By following a balanced diet, exercising regularly, and monitoring your weight periodically, your body can maintain its energy balance more steadily.
However, in certain conditions, changes in body weight can occur due to medical factors. That is why it is important to understand when weight changes need medical attention.
This will be discussed further in the next section: when you should consult a doctor.
When Should You Consult a Doctor?
Knowing how to calculate ideal body weight helps you understand whether your current weight is within a healthy range. However, that number does not always give a complete picture of a person’s health.
In some situations, consulting a doctor can help assess your body more thoroughly. Doctors look not only at body weight or body mass index (BMI), but also consider other factors such as medical history, body fat distribution, and the risk of chronic diseases, including heart disease.
That is why, if the results of your ideal body weight calculation show an imbalance or if you have certain health risk factors, a medical examination can be an important step to make sure your body stays healthy.
1. When Your BMI Shows Overweight or Obesity
One of the methods often used in calculating ideal body weight is the body mass index (BMI). This calculation compares body weight with height to classify a person’s weight status.
According to the Indonesian Ministry of Health classification, BMI in adults is categorized as follows:
- BMI > 25.0 to 27.0 → overweight
- BMI > 27.0 → obesity
If your BMI falls into one of these categories, consulting a doctor can help determine the next steps. A doctor can:
- Assess whether excess weight has affected your health
- Identify the risk of metabolic diseases
- Provide safe and realistic weight loss recommendations
This is important because obesity is known to be associated with an increased risk of heart disease, type 2 diabetes, and high blood pressure.
2. When Your Weight Is Hard to Lose Despite Your Efforts
Many people have tried various methods to lose weight, from adjusting their diet to increasing physical activity. However, in some cases, the weight still does not come off easily.
If this happens, you should consult a doctor. In fact, difficulty losing weight is not always related to diet alone.
Some medical factors that can affect body weight include:
- Hormonal or metabolic disorders
- Side effects of certain medications
- Chronic sleep disorders
- Medical conditions such as hypothyroidism or insulin resistance
That is why a doctor can help carry out a further evaluation. Then, if needed, the doctor may recommend laboratory tests or a treatment approach that better suits your body’s condition.
This approach helps ensure that your weight management strategy is not only effective, but also safe in the long term.
3. Having Risk Factors for Heart Disease
Besides body weight, other factors can also affect heart health. The following conditions can increase the risk of cardiovascular disease:
- High cholesterol
- High blood pressure (hypertension)
- Diabetes or high blood sugar levels
If you have one or more of these risk factors, especially along with excess body weight, a health checkup becomes even more important.
In this situation, a doctor can help:
- Assess heart disease risk more comprehensively
- Check blood pressure, cholesterol levels, and blood sugar
- Provide appropriate lifestyle change recommendations
Furthermore, a medical evaluation also helps detect health problems early, so that treatment can be given sooner.
4. A Doctor Can Provide a More Thorough Health Evaluation
It is important to understand that body weight is not the only indicator of health. Two people with the same BMI do not necessarily have identical health conditions.
That is why doctors usually carry out a more comprehensive assessment, such as:
- Measuring waist circumference to assess body fat distribution
- Evaluating personal and family medical history
- Assessing diet, physical activity, and daily habits
- Performing supporting tests, such as blood tests if needed
This approach helps ensure that efforts to maintain an ideal body weight focus not only on the number on the scale, but also on overall metabolic and heart health.

Conclusion
Understanding how to calculate ideal body weight is an important first step in recognizing your body’s health. By knowing your healthy weight range, you can assess whether your diet, physical activity, and lifestyle support your overall health.
In general, ideal body weight can be calculated using several methods, from the Broca formula and body circumference measurements to the method most often used in health practice, the body mass index (BMI). The BMI method is widely used because the calculation is simple and can give an initial picture of a person’s weight status.
BMI is widely used to classify whether a person falls into the normal weight, overweight, or obese category. This information helps health professionals assess potential health risks that may arise from an unbalanced body weight.
However, it is important to understand that no single method can perfectly describe a person’s health. BMI, for example, does not distinguish between fat mass and muscle mass. That is why the results of your ideal body weight calculation should be used as an initial guide to understanding your body, not as the sole indicator of health.
On the other hand, keeping your weight within a healthy range has very important benefits for the body. In fact, various studies show that excess body weight can increase the risk of a number of chronic diseases. Excess weight is linked to an increased risk of high blood pressure, unhealthy cholesterol levels, type 2 diabetes, and heart disease.
That is why, after understanding how to calculate ideal body weight, the next step is to keep your weight stable through healthy habits. Some simple steps you can take include:
- Eating a balanced, nutritious diet
- Being physically active regularly
- Monitoring your weight periodically
- Consulting a medical professional if needed
Ultimately, the goal of understanding how to calculate ideal body weight is not just to reach a certain number on the scale. Rather, this information can serve as a guide to building sustainable healthy habits. By keeping your weight within a healthy range, you also help lower the risk of various diseases and protect your heart health in the long term.

Frequently Asked Questions.
Here are some frequently asked questions about how to calculate ideal body weight and what BMI values mean for your health.
How Do You Calculate Ideal Body Weight?
Ideal body weight can be calculated using several methods commonly used in healthcare. One of the most frequently used is the body mass index (BMI), which divides body weight (in kilograms) by the square of height (in meters). There is also the Broca formula, which estimates ideal body weight based on height. However, these calculations should be used only as an initial guide and do not replace a comprehensive health assessment by a medical professional.
What BMI Is Considered Normal?
According to the Indonesian Ministry of Health classification, a normal BMI for adults is in the range of 18.5 to 25.0. A person with a BMI below 18.5 is classed as underweight, a BMI above 25.0 up to 27.0 indicates overweight, and a BMI above 27.0 is classed as obesity. However, BMI does not always describe body composition in detail, because this method does not distinguish between muscle mass and fat.
Is Ideal Body Weight the Same for Men and Women?
Ideal body weight is not always the same for men and women, even though it is often calculated with similar formulas such as BMI. Biologically, men usually have more muscle mass than women, while women tend to have a higher percentage of body fat. These differences in body composition mean that the weight range considered healthy may differ. That is why, when assessing ideal body weight, health professionals also consider other factors such as age, body composition, physical activity, and overall health.
Can BMI Determine Obesity?
BMI can be used as an initial screening tool to help determine whether a person has obesity. According to the Indonesian Ministry of Health classification, a person is classed as obese if their BMI is above 27.0. However, BMI cannot directly confirm how much body fat a person has. Therefore, in medical practice, doctors usually combine BMI with other assessments such as waist circumference measurement, medical history, and metabolic risk factors to assess obesity more accurately.
Is BMI Linked to Heart Disease Risk?
BMI is linked to the risk of various chronic diseases, including heart disease. When BMI is above the normal range, the risk of high blood pressure, unhealthy cholesterol levels, type 2 diabetes, and heart disease may increase. This is also explained by the American Heart Association, which states that overweight and obesity are important risk factors for heart health. That is why monitoring your BMI regularly may help you understand your health and take preventive steps earlier through a healthy diet, regular physical activity, and routine health checkups.
