How to use this calculator
- Enter your waist and height in the same unit.
- Press Calculate for the ratio and category.
How it works
Divide your waist by your height. A ratio under 0.5 is commonly considered healthy; higher values point to more central body fat. It's a quick screen, not a diagnosis.
Worked example
Waist 80 cm, height 180 cm. 80 ÷ 180 = 0.44 — within the healthy range.
