Frequently asked questions

What is a healthy BMI?

For adults, a BMI between 18.5 and 24.9 is considered normal weight. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese.

Is BMI accurate?

BMI is a useful screening tool but has limitations. It does not account for muscle mass, age, or body fat distribution. Athletes may have a high BMI despite being healthy.

What is my BMI if I am 180 cm and 80 kg?

Your BMI is 24.7, which falls in the normal weight range.

How is BMI calculated?

BMI is calculated by dividing your weight in kilograms by your height in metres squared. For example: 80 kg ÷ (1.80 × 1.80) = 24.7.
