What is a BMI Calculator?
A BMI Calculator estimates your body mass index using your height and weight.
BMI is a simple screening indicator and does not directly measure body fat, muscle mass, age, sex, or overall health condition.

- Enter your height in centimeters and weight in kilograms.
- If auto calculation is enabled, the result appears as you type.
- Use Copy Result to save or share the calculation result.
Which BMI standard should I use?
The Asian standard is commonly used in Korea, Japan, China, and other Asian regions. The WHO standard is commonly used for international or English-language references.
Can BMI determine my health condition by itself?
No. BMI is only a basic height-and-weight based indicator. Muscle mass, body composition, age, sex, and medical conditions can affect the interpretation.
How is the healthy weight range calculated?
The healthy weight range is calculated from your height using the normal BMI range of the selected standard.
