Body mass index with metric or imperial units, your WHO weight category and the healthy range for your height.
Enter your height and weight.
The WHO classifies 18.5–24.9 as normal weight, below 18.5 as underweight, 25–29.9 as overweight, and 30+ as obese.
BMI is a population screening tool. It overestimates body fat in muscular athletes and underestimates it in older adults — use it as a starting point, not a diagnosis.
