This body analysis calculator brings several health metrics together — BMI, estimated body fat, BMR, and waist-to-height ratio — for a fuller picture than any single number. Enter your details above.
What it combines
- BMI = weight(kg) ÷ height(m)²
- Body fat — US Navy tape estimate
- BMR — Mifflin-St Jeor
- Waist-to-height — central-fat indicator
Together these give a rounder view than BMI alone, which cannot tell muscle from fat.

Frequently Asked Questions
What is a full body analysis?
A combined view of several body metrics — BMI, body fat, BMR, and waist-to-height — rather than relying on one number.
Why not just use BMI?
BMI cannot distinguish muscle from fat. Adding body fat and waist measures gives a more complete picture.
Are these measurements exact?
They are estimates from formulas. For precise body composition, methods like DEXA are more accurate.
