How It Works
Our body shape calculator uses a simple, well-established method called the waist-to-hip ratio (WHR). The process takes less than two minutes and gives you immediate results with clear explanations.
Measure Your Waist
Using a soft measuring tape, measure around the narrowest part of your waist — usually just above your belly button. Stand relaxed, breathe normally, and keep the tape snug but not tight. Measure over thin clothing or bare skin for best accuracy. If you're unsure where your natural waist is, try bending slightly to the side — the crease that forms is your waistline.
Measure Your Hips
Wrap the tape around the widest part of your hips and buttocks. Keep the tape parallel to the floor and make sure it sits flat without twisting. Stand with feet together and don't compress the tape into your skin. Check in a mirror to ensure the tape is level all the way around — this is the most common source of measurement error.
See Your Results
Enter both measurements into the calculator and instantly see your waist-to-hip ratio along with a commonly used body shape category. The calculator shows your WHR as a decimal (for example, 0.75), explains what that number means, and provides context about body shape terminology. You can save your results, download them as a PDF, or share them — all without creating an account.
