Questions
About this tool
Is BMI a diagnosis?
No. BMI is a population-level screening measure and does not directly measure body fat, fitness, health, pregnancy, or individual risk. Ask a qualified clinician for personal guidance.
Is this suitable for children?
No. Child and teen BMI uses age- and sex-specific percentiles; this calculator is for adults only.
