⚖️ BMI / Health Calculator
Calculate BMI, adult category, healthy BMI weight range, and a copyable health estimate summary.
Health estimate note
- BMI is a rough population-level screening metric and does not diagnose health, fitness, or body composition.
- Do not use this page for medical decisions; talk with a qualified clinician for personal health guidance.
BMI checks
Validates height and weight ranges, calculates standard adult BMI categories, and always includes limitations because BMI does not measure body composition or individual health risk.
Why it is useful
BMI is a quick population-level screening metric that can provide a rough reference point when discussing weight-related health information.
How it works
The calculator applies the standard BMI formula using your chosen units, then compares the result with common adult BMI category ranges.
Best input
Use current height and weight values. For children, athletes, pregnancy, older adults, or clinical decisions, BMI alone is not enough.
Privacy note
Height and weight are processed locally in your browser.
Important limitation
BMI is not medical advice and does not measure body composition, fitness, nutrition, or individual health risk. Talk to a qualified clinician for personal guidance.
Quick answers
Is BMI accurate for everyone?
