range for your height
BMI (Body Mass Index) relates your weight to your height to estimate whether you're in a healthy range. It's a quick, globally used guide, though it doesn't distinguish fat from muscle.
How is BMI calculated?
BMI is your weight (kg) divided by the square of your height (m). For example, 70 kg / (1.65 m)² = 25.7. The WHO considers a BMI between 18.5 and 24.9 healthy.
Frequently asked questions
What is a healthy BMI?
Per the WHO, a BMI between 18.5 and 24.9 is a healthy weight. Below is underweight; 25–29.9 is overweight; 30 or more is obese.
Does BMI work for everyone?
It's a general guide. It doesn't tell fat from muscle, so it can overestimate in very muscular people. Use it as a starting point, not a diagnosis.
