BMI Calculator by Age & Gender
Age- and gender-aware BMI interpretation with an ideal weight range.
About the BMI Calculator by Age & Gender
BMI Calculator by Age & Gender applies the raw BMI formula and then interprets the result according to your age band: children and teens use percentile charts, adults use WHO cut-offs, and seniors (65+) use slightly higher 'healthy' thresholds.
How to use
- Pick gender and enter your age in years.
- Enter weight (kg) and height (cm).
- Click Calculate BMI — category, healthy range and interpretation appear together.
Benefits & key features
- Age-aware interpretation — a 70-year-old is judged differently from a 30-year-old.
- Separate ideal ranges for men and women.
- Quick health-risk screening at home.
- Recommends follow-up tools like TDEE and Body-Fat for context.
Pro tip
Muscular individuals sometimes register 'overweight' by BMI but have low body-fat. Use this tool alongside the Body Fat (Navy Method) for a fuller picture.
