Waist-to-Height Ratio Calculator

Calculate your Waist-to-Height Ratio (WHtR) — a better predictor of cardiovascular risk than BMI. Check if your waist circumference is in the healthy range.

What is Waist-to-Height Ratio Calculator?

This waist-to-height ratio calculator divides your waist circumference by your height to assess central obesity and cardiometabolic risk. WHtR is considered a superior health indicator to BMI because it directly measures abdominal fat, which is the most dangerous type of body fat.

Frequently Asked Questions

What is a healthy waist-to-height ratio?

WHtR below 0.5 is healthy — this means your waist should be less than half your height. 0.5–0.6 is overweight/increased risk. Above 0.6 is obese/high risk. This rule works for all ages, genders, and ethnicities, making it simpler than BMI.

Why is WHtR better than BMI?

BMI cannot distinguish between muscle and fat, or where fat is stored. WHtR directly measures visceral (belly) fat, which is linked to heart disease, diabetes, and stroke. A muscular person may have high BMI but healthy WHtR.
