Question 1

How accurate is the BMI Calculator?

Accepted Answer

The calculator follows WHO guidelines and uses the standard BMI formula (weight/height²), offering reliable results for most adults. However, BMI doesn't account for muscle mass, bone density, or body composition.

Question 2

Can BMI measure body fat percentage?

Accepted Answer

No. BMI estimates weight relative to height but doesn't measure fat directly. For exact body fat percentage, you'll need a body composition test like DEXA scan or bioelectrical impedance.

Question 3

What is considered a healthy BMI range?

Accepted Answer

According to WHO standards, a BMI between 18.5 and 24.9 is generally considered healthy for adults. Under 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

Question 4

Is BMI accurate for athletes and bodybuilders?

Accepted Answer

BMI may overestimate body fat in athletes and bodybuilders due to higher muscle mass. Muscle weighs more than fat, so muscular individuals may have high BMI despite low body fat.

Question 5

Do I need to create an account to use the calculator?

Accepted Answer

No. The tool works instantly without any sign-up or registration. All calculations happen in your browser, and we don't store any personal data.
