Frequently Asked Questions
How is BMI calculated?
BMI = weight (kg) ÷ height (m)². For example, 65 kg at 5′7″ (1.70 m) gives 65 ÷ 2.89 ≈ 22.5.
What is a healthy BMI range?
The WHO classes a BMI of 18.5–24.9 as a healthy weight, under 18.5 as underweight, 25–29.9 as overweight, and 30 or above as obese.
Is BMI accurate for everyone?
BMI is a useful general screen but does not distinguish muscle from fat, so it can over-estimate body fat in very muscular people and under-estimate it in others. Use it as a guide alongside other measures.
