- Summary
Body mass index (BMI) uses a person’s height and weight to help determine if they are a moderate weight. BMI charts also display the ranges for the categories of underweight, overweight, and obesity.
Carrying too much or too little weight can increase a person’s risk of health problems, either in the present or the future.
A person’s BMI is not the only factor that affects this risk. Other tools for assessing whether or not a person has a healthy weight or body composition for them include waist-to-hip ratio, waist-to-height ratio, and body fat percentage.
However, BMI is a useful starting point. This article provides some tools for people to work out their BMI.
These calculators and charts can give an indication of whether or not a person’s weight may affect their risk of health problems.
This article publishes the calculators courtesy of The Calculator Site. There are two calculation options available: metric and imperial.
To use the charts below, a person can find their weight in pounds along the top and their height in feet and inches down the side. They can then look across to find their BMI.
There are two charts. If a person’s weight is 245 pounds (lb) or under, they should use the first chart. If their weight is over 250 lb, they should look at the second one.
The shaded areas correspond to BMI values that indicate either a moderate weight, overweight, or obesity.
In addition, researchers and doctors divide obesity into three categories:
•Class 1: BMI is 30–34.9.
•Class 2: BMI is 35–39.9.
The following table shows the standard weight status categories associated with BMI ranges for adults:
BMI of under 18.5
A BMI of under 18.5 indicates that a person has insufficient weight, so they may need to put on some weight. They should ask a doctor or dietitian for advice.
BMI of 18.5–24.9
A BMI of 18.5–24.9 indicates that a person has a healthy weight for their height. By maintaining a healthy weight, they can lower their risk of developing serious health problems.
BMI of 25–29.9
Maintaining a moderate weight can help prevent a range of health conditions.
People who are overweight may have a higher risk than others of conditions such as heart disease, type 2 diabetes, sleep apnea, and colorectal cancer. Some of these can be life threatening.
Some evidence suggests that the associations between BMI, body fat percentage, and body fat distribution may differ across populations due to variations in sex, race, and ethnicity.
A Brazilian study from 2017 looked at the correlation between BMI and body fat percentage in 856 adult males and females.
They concluded that to predict obesity-type body fat percentage, the standard BMI threshold of 29.9 kilograms per square meter (kg/m2) was appropriate for males but that a more suitable cutoff point for females appeared to be 24.9 kg/m2.
In 2017, Korean researchers pointed out that people in the Asia-Pacific region often have a higher risk of type 2 diabetes and cardiovascular disease at a BMI below the existing World Health Organization (WHO) cutoff point of 25 kg/m2.
In Korea, they added, there is evidence to suggest that almost twice as many people have features of metabolic obesity but a moderate weight compared with the United States.
The results of one 2011 study found that Asian American people within the healthy weight range were more likely to have symptoms of metabolic syndrome than their non-Hispanic white counterparts.
BMI is a useful tool that gives a general idea about whether or not a person’s weight is healthy for them.
However, it is a simple tool that does not tell the whole story about people’s individual weight and health risks.

To determine how much you should weigh (your ideal body weight) several factors should be considered, including age, muscle-fat ratio, height, sex, and bone density.
If your BMI is 30.0 or higher, it falls within the obese range. Weight that is higher than what is considered as a healthy weight for a given height is described as overweight or obese. Weight that is lower than what is considered as healthy for a given height is described as underweight. 1
