The ideal weight for a person depends on various factors such as age, height, gender, body composition, and activity level. It’s not appropriate to provide a specific weight without considering these factors.
However, there are several tools and calculators available online that can give you a rough estimate of your ideal weight range based on your height and age. One commonly used method is the body mass index (BMI) which is a measure of body fat based on height and weight.
You can use an online BMI calculator to determine your BMI, and the National Institutes of Health (NIH) provides the following guidelines for interpreting BMI results:
- BMI less than 18.5: underweight
- BMI between 18.5 and 24.9: normal weight
- BMI between 25 and 29.9: overweight
- BMI of 30 or greater: obese
However, it’s important to note that BMI is not always accurate and doesn’t take into account factors such as muscle mass or body composition. It’s best to consult with a healthcare professional for personalized advice on maintaining a healthy weight.
Body mass index (BMI)
Body mass index (BMI) is a measure of body fat based on a person’s weight and height. It is calculated by dividing a person’s weight (in kilograms) by the square of their height (in meters). The formula is:
BMI = weight (kg) / height² (m²)
BMI is used as a screening tool to determine whether a person is underweight, normal weight, overweight, or obese. The BMI ranges for adults are:
- BMI less than 18.5: underweight
- BMI between 18.5 and 24.9: normal weight
- BMI between 25 and 29.9: overweight
- BMI of 30 or greater: obese
However, it’s important to note that BMI is not always accurate and doesn’t take into account factors such as muscle mass or body composition. It’s best to consult with a healthcare professional for personalized advice on maintaining a healthy weight.
Body mass index calculator
There are many body mass index (BMI) calculators available online. Here is one example of how to use a BMI calculator:
- Go to a trusted website that offers a BMI calculator. One example is the National Heart, Lung, and Blood Institute’s calculator
- Enter your height in feet and inches or in centimeters, and your weight in pounds or in kilograms.
- Click on “Calculate BMI” to see your BMI score.
- Check the result to see which category you fall under, based on the BMI ranges for adults:
- BMI less than 18.5: underweight
- BMI between 18.5 and 24.9: normal weight
- BMI between 25 and 29.9: overweight
- BMI of 30 or greater: obese
Remember that BMI is not always a perfect measure of health, as it does not account for factors such as muscle mass or body composition. Consult with a healthcare professional for personalized advice on maintaining a healthy weight.
Weight and height guide chart
Here is a general weight and height guide chart for adults based on the body mass index (BMI) ranges:
BMI less than 18.5: Underweight BMI between 18.5 and 24.9: Normal weight BMI between 25 and 29.9: Overweight BMI of 30 or greater: Obese
Height and weight are individual characteristics that can vary greatly based on factors such as age, gender, body composition, and activity level. This chart should be used as a rough guide and not as a definitive measure of health.
It’s important to note that BMI is not always accurate and doesn’t take into account factors such as muscle mass or body composition. It’s best to consult with a healthcare professional for personalized advice on maintaining a healthy weight.
BMI based on age
BMI is calculated based on the same formula for all adults, regardless of age. However, BMI ranges that are considered healthy may vary slightly for older adults compared to younger adults.
As we age, we tend to lose muscle mass and bone density, which can affect our weight and BMI. Therefore, BMI ranges for older adults may be slightly higher than those for younger adults.
The following BMI ranges are generally considered healthy for older adults:
- BMI less than 22: underweight
- BMI between 22 and 27: normal weight
- BMI between 27 and 30: overweight
- BMI greater than 30: obese
However, it’s important to note that BMI is not always accurate and doesn’t take into account factors such as muscle mass or body composition. It’s best to consult with a healthcare professional for personalized advice on maintaining a healthy weight as you age.
What is the problem with BMI?
While BMI is a useful tool for measuring body fat in many cases, it has some limitations and is not always an accurate indicator of health. Here are some of the problems with BMI:
- It doesn’t account for body composition: BMI is calculated based on height and weight alone and does not take into account factors such as muscle mass or body fat percentage. As a result, someone with a high amount of muscle mass may have a high BMI even though they are not overweight or obese.
- It doesn’t distinguish between fat and muscle: Since BMI only takes into account height and weight, it does not distinguish between fat and muscle. Therefore, a person who is very muscular may have a high BMI even if they have a low body fat percentage.
- It doesn’t consider other health factors: BMI does not take into account other factors that may affect a person’s health, such as blood pressure, cholesterol levels, or blood sugar levels.
- It may not be accurate for certain populations: BMI may not be accurate for certain populations, such as athletes, older adults, or pregnant women.
- It can be misleading: BMI ranges can be misleading since there are some people with a healthy BMI who have a higher risk for health problems and vice versa.
Despite these limitations, BMI can still be a useful tool for assessing overall health risks. However, it’s important to also consider other factors and to consult with a healthcare professional for personalized advice on maintaining a healthy weight.
Waist-to-hip ratio (WHR)
Waist-to-hip ratio (WHR) is a measure of body fat distribution that compares the circumference of the waist to that of the hips. It is calculated by dividing the waist measurement by the hip measurement. The formula is:
WHR = waist circumference / hip circumference
A higher WHR indicates that a person has more fat stored around their waist, which is associated with a higher risk of health problems such as heart disease, diabetes, and stroke.
For women, a healthy WHR is generally considered to be less than 0.85, while for men it is less than 0.90. A WHR above these values is considered to indicate an increased risk of health problems.
It’s important to note that WHR should be used in conjunction with other measures of health, such as BMI, blood pressure, and cholesterol levels. A healthcare professional can help interpret WHR results and provide personalized advice on maintaining a healthy weight and reducing health risks.
Measuring WHR
To measure waist-to-hip ratio (WHR), you’ll need a tape measure and a flat surface to stand on. Here are the steps:
- Stand up straight and relax your abdominal muscles.
- Measure your waist: Wrap the tape measure around your waist at the level of your navel. Make sure the tape measure is snug but not too tight. Record the measurement in inches or centimeters.
- Measure your hips: Wrap the tape measure around the widest part of your hips (usually at the level of the hip bones). Make sure the tape measure is snug but not too tight. Record the measurement in inches or centimeters.
- Calculate your WHR: Divide your waist measurement by your hip measurement to get your WHR.
For example, if your waist measurement is 32 inches and your hip measurement is 40 inches, your WHR would be 0.8 (32 divided by 40).
Remember that WHR should be used in conjunction with other measures of health, such as BMI, blood pressure, and cholesterol levels. A healthcare professional can help interpret WHR results and provide personalized advice on maintaining a healthy weight and reducing health risks.
What does it mean?
The meaning of your waist-to-hip ratio (WHR) depends on the value you calculated. In general, a higher WHR indicates that you have more fat stored around your waist, which is associated with a higher risk of health problems such as heart disease, diabetes, and stroke.
For women, a healthy WHR is generally considered to be less than 0.85, while for men it is less than 0.90. A WHR above these values is considered to indicate an increased risk of health problems.
However, it’s important to note that WHR should be used in conjunction with other measures of health, such as BMI, blood pressure, and cholesterol levels. A healthcare professional can help interpret WHR results and provide personalized advice on maintaining a healthy weight and reducing health risks.
Waist-to-height ratio
Waist-to-height ratio (WHtR) is a measure of body fat distribution that compares the circumference of the waist to the height of a person. It is calculated by dividing the waist circumference by the height.
The formula is: WHtR = waist circumference / height
Unlike BMI, WHtR takes into account the distribution of body fat, which is important in assessing overall health risks. A higher WHtR indicates a higher amount of abdominal fat, which is associated with an increased risk of health problems such as heart disease, diabetes, and stroke.
For adults, a healthy WHtR is generally considered to be less than 0.5. A WHtR above this value is considered to indicate an increased risk of health problems.
Measuring WHtR is similar to measuring WHR. You’ll need a tape measure and a flat surface to stand on. Here are the steps:
- Stand up straight and relax your abdominal muscles.
- Measure your waist: Wrap the tape measure around your waist at the level of your navel. Make sure the tape measure is snug but not too tight. Record the measurement in inches or centimeters.
- Measure your height: Stand barefoot against a wall, with your back straight and your heels, buttocks, and shoulders touching the wall. Have someone measure your height in inches or centimeters, from the top of your head to the floor.
- Calculate your WHtR: Divide your waist measurement by your height in inches or centimeters to get your WHtR.
For example, if your waist measurement is 32 inches and your height is 64 inches, your WHtR would be 0.5 (32 divided by 64).

Body fat percentage
Body fat percentage is the proportion of your total body weight that is made up of fat. It is an important measure of overall health, as carrying too much body fat can increase your risk of health problems such as heart disease, diabetes, and stroke.
There are several methods for measuring body fat percentage, including:
- Skinfold measurements: A caliper is used to measure the thickness of skinfolds at various points on the body, which is then used to calculate body fat percentage.
- Bioelectrical impedance analysis (BIA): This method involves passing a small electrical current through the body to measure the resistance of body tissue. This information is used to calculate body fat percentage.
- Dual-energy X-ray absorptiometry (DEXA): This method uses X-ray technology to measure bone density, fat mass, and lean body mass. It is considered one of the most accurate methods for measuring body fat percentage.
- Hydrostatic weighing: This method involves submerging the body in water and measuring the displacement of water to calculate body density, which is then used to calculate body fat percentage.
- Air displacement plethysmography (ADP): This method uses a specialized chamber to measure the volume of air displaced by the body, which is then used to calculate body density and body fat percentage.
A healthy body fat percentage varies depending on age, gender, and other factors. In general, for men, a healthy body fat percentage is considered to be between 10-20%, while for women, it is considered to be between 20-30%. However, it’s important to note that these ranges can vary depending on individual factors and health goals. A healthcare professional can help interpret body fat percentage results and provide personalized advice on maintaining a healthy weight and reducing health risks.
How to measure body fat
There are several methods for measuring body fat percentage. Here are some of the most common methods:
