How the Waist Hip Ratio Calculator works

WHR = waist \u00f7 hip (same units)
  • waist — At the narrowest point
  • hip — At the widest point

Understanding the inputs

What each value means, why it matters, and a typical range — so you can fill in the calculator with confidence.

Waist Circumference

The distance around your waist, measured with a tape.

Why it matters:
It estimates body fat and flags health risk from belly fat.
Typical range:
Health risk rises above about 94 cm (men) and 80 cm (women).
How it affects results:
  • Higher: Generally higher estimated body fat and risk.
  • Lower: Generally lower estimated body fat and risk.

Common mistake: Measuring at the wrong spot or pulling the tape too tight.

I built a free mortgage calculator that works instantly in the browser — no signup, no ads in your face
Body
Hey r/[subreddit],

I kept needing a quick mortgage calculator and most options online were slow or behind paywalls, so I built one that:

• Runs 100% in your browser (your data never leaves your device)
• No signup, no email wall, no popups
• Loads in under a second on mobile

It covers the standard mortgage use cases (mortgage, home, loan, payment) and links out to the formula + worked examples if you want to learn the math.
