Frequently asked questions
Is BMI an accurate measure of health?
BMI is a general screening tool based only on height and weight, and doesn't account for muscle mass, body composition, or individual differences, so it's best used as a starting point rather than a full health assessment.
What BMI range is considered typical?
A BMI between 18.5 and 24.9 is commonly cited as the typical range, though healthy ranges can vary by individual and population.
