BMI Calculator

Body Mass Index (BMI) is a simple and widely used measurement tool that can help you determine if your weight is in a healthy range based on your height.

It is calculated by dividing your weight (in kilograms) by the square of your height (in meters). BMI is a useful tool for both adults and children to assess their weight status and potential health risks associated with being overweight or underweight.

In this article, we will discuss the BMI calculator, including the BMI table and chart for adults and children.

BMI Table for Adults:

BMI is commonly used to assess the weight status of adults. The following table shows the BMI categories and their corresponding ranges:

BMI Category BMI Range

Underweight < 18.5

Normal weight 18.5 - 24.9

Overweight 25.0 - 29.9

Obesity >= 30.0

If your BMI falls under the "normal weight" category, it means that you are in a healthy weight range for your height.

However, if your BMI falls under the "underweight" category, it may indicate that you are not getting enough nutrients or are experiencing a health issue that requires medical attention.

On the other hand, if your BMI falls under the "overweight" or "obesity" categories, it may indicate that you are at a higher risk for certain health issues such as diabetes, heart disease, and high blood pressure.

BMI Chart for Adults:

The BMI chart for adults is another useful tool that can help you assess your weight status. The chart shows your weight in kilograms on the horizontal axis and your height in meters on the vertical axis.

To use the chart, find your height on the vertical axis and follow the line across to your weight on the horizontal axis. The point where the two lines meet is your BMI.

BMI Table for Children and Teens:

The BMI calculation for children and teens is slightly different from that of adults. This is because children's and teens' BMIs need to be adjusted for their age and sex as their body composition changes as they grow.

The following table shows the BMI categories and their corresponding ranges for children and teens aged 2 to 20 years:

BMI Category BMI Range

Underweight < 5th percentile

Normal weight 5th to 85th percentile

Overweight 85th to 95th percentile

Obesity >= 95th percentile

The BMI percentile is determined by comparing a child's or teen's BMI to others of the same age and sex. For example, a BMI percentile of 50 means that the child's BMI falls in the middle of the BMI distribution for their age and sex.

A BMI percentile below 5 indicates that the child or teen is underweight, while a percentile between 5 and 85 indicates that they are at a healthy weight.

A percentile between 85 and 95 indicates that the child or teen is overweight, and a percentile above 95 indicates that they are obese.

BMI Chart for Children and Teens:

The BMI chart for children and teens is also different from that of adults. The chart shows BMI percentiles on the vertical axis and age on the horizontal axis.

To use the chart, find your child's age on the horizontal axis and follow the line up to their BMI percentile on the vertical axis. The chart can help you assess whether your child or teen is at a healthy weight for their age and sex.

The Body Mass Index (BMI) calculator

The Body Mass Index (BMI) calculator is a widely used tool that measures the body fat of an individual in relation to their weight and height.

The calculation of BMI is based on a simple formula, where the weight of an individual in kilograms is divided by their height in meters squared.

The resulting number indicates the degree of body fat, and whether an individual is considered to be underweight, normal weight, overweight or obese.

BMI Chart for Children and Teens:

The BMI chart for children and teens is an important tool for parents and healthcare professionals to determine whether a child is growing at a healthy rate.

BMI calculations for children and teens differ from those for adults as they are dependent on age and gender-specific percentiles. The BMI percentile is determined by comparing a child's BMI to other children of the same age and gender.

The BMI chart for children and teens ranges from age 2-20 years, and it helps to identify children and teens who may be at risk for developing obesity, which is associated with numerous health problems such as high blood pressure, type 2 diabetes, heart disease, and sleep apnea.

BMI Risks Associated with Being Overweight:

Being overweight or obese, according to the BMI chart for children and teens, can result in numerous health problems that can affect the quality of life of an individual.

Children and teens who are overweight are at higher risk for developing type 2 diabetes, high blood pressure, asthma, sleep apnea, fatty liver disease, and cardiovascular disease.

Obesity in children can also lead to social and psychological problems such as depression, anxiety, and low self-esteem.

Therefore, it is crucial for parents to monitor their child's weight and consult with a healthcare professional if their child is at risk of becoming overweight.

BMI Risks Associated with Being Underweight:

Being underweight, according to the BMI chart for children and teens, can also result in numerous health problems.

Children and teens who are underweight may not be getting enough nutrients to support their growth and development. This can lead to delayed growth and development, malnutrition, anemia, and weakened immune system.

Underweight children may also have a higher risk of developing infections and illnesses, and they may be more prone to bone fractures and injuries.

Limitations of BMI:

The Body Mass Index (BMI) is a commonly used metric to determine a person's weight status. However, there are several limitations of BMI, including:

Doesn't differentiate between muscle and fat: BMI does not distinguish between muscle mass and fat mass, which can lead to misclassification of people who have a high muscle mass as overweight or obese.

Not accurate for athletes:

BMI may not be accurate for athletes and bodybuilders who have high muscle mass and low body fat. They may have a high BMI, but their body fat percentage may be within a healthy range.

Doesn't take into account body shape:

BMI does not consider body shape or fat distribution, which can impact health risks. For example, people who carry more fat around their waist (apple-shaped) have a higher risk of health problems than those who carry fat around their hips (pear-shaped).

May not be accurate for the elderly:

BMI may not be accurate for elderly people as they tend to have lower muscle mass and bone density, which can lead to an underestimation of their body fat percentage.

Doesn't consider ethnicity:

BMI may not be suitable for all ethnic groups, as different ethnicities can have different body compositions and health risks.

Overall, while BMI can provide a general idea of a person's weight status, it should be used in conjunction with other health markers, such as body fat percentage, waist circumference, and blood pressure, to get a more accurate picture of an individual's health.
