Frequently asked questions

Is BMI accurate for everyone?
BMI is a useful screening tool but doesn't account for muscle mass, bone density or body composition, so it may be less accurate for athletes, older adults or pregnant people.
What is a healthy BMI range?
For most adults, the WHO considers 18.5–24.9 to be within the normal weight range.
Does this tool store my data?
