Frequently asked questions
Is BMI accurate for everyone?
BMI is a useful general screening tool, but it doesn't distinguish muscle from fat - it can overestimate body fat in muscular athletes and underestimate it in older adults with reduced muscle mass. Treat it as one data point, not a full health assessment.
What is a healthy BMI range?
For most adults, 18.5-24.9 is considered a normal range, 25-29.9 overweight, and 30+ obese - but healthy ranges can vary by age, sex, and body composition, so discuss individual results with a healthcare provider.
Does this calculator work in both metric and imperial units?
Yes - you can enter height and weight in either kilograms/centimetres or pounds/feet-inches.
