Waist-to-Height Ratio Calculator
Calculate your waist-to-height ratio (WHtR) and see where it falls on standard health bands. A simple, research-backed health screening metric.
Waist-to-Height Ratio
Enter your waist and height in the same unit
Measure around the navel, relaxed, not sucking in.

WHtR = waist ÷ height, plus its health band
Waist-to-height ratio captures abdominal (central) fat, which carries more metabolic risk than overall weight.
A single threshold — waist under half your height — applies to most adults regardless of stature.
Central fat is often among the first to reduce on a sustained deficit, so WHtR is a useful way to track progress.
- 1Measure your waist: around the navel, relaxed, with a flexible tape that's snug but not compressing.
- 2Enter your height: in the same unit as the waist (in or cm) — the ratio is unit-independent.
- 3Read your ratio: WHtR = waist ÷ height, and see which health band the number falls in.
Important Notes
WHtR is a screening metric, not a diagnosis. Very low ratios (under ~0.4) may also carry health concerns. Use it alongside other health markers and consult a healthcare professional for personalized advice.
