Body shape calculator
Enter your bust, waist and hip measurements to find your shape and what to wear for it. It runs in your browser, so nothing you type is saved or sent anywhere.
How to measure
- Stand up straight with your feet together, in light clothing or underwear.
- Bust: wrap the tape around the fullest part of your chest, keeping it level across your back.
- Waist: measure the narrowest part of your torso, usually just above the navel. Breathe out normally and don’t pull the tape tight.
- Hips: measure around the fullest part of your hips and bottom, with your feet together.
- Keep the tape snug but not tight, parallel to the floor, and use the same unit for all three.
How the calculator decides
Your shape comes from three ratios. The rules are checked in this order, and the first one that matches wins.
| Shape | Rule |
|---|---|
| Apple | Waist is 85% or more of the wider of bust and hips |
| Pear | Hips are at least 5% bigger than the bust |
| Inverted triangle | Bust is at least 5% bigger than the hips |
| Hourglass | Bust and hips within 5%, waist 75% or less of the wider |
| Rectangle | Bust and hips within 5%, waist between 75% and 85% |
These cutoffs are a common convention, not a scientific standard. Read more on the about and method page.
The five shapes
- HourglassAn hourglass shape has a bust and hips of similar size with a clearly narrower waist.
- PearA pear shape has hips wider than the bust, with a waist that is noticeably narrower than the hips.
- Inverted triangleAn inverted triangle has a bust and shoulder line that are wider than the hips.
- RectangleA rectangle shape has a bust, waist and hips that are close in size, so the waist is not sharply defined.
- AppleAn apple shape carries more width at the midsection, so the waist is close in size to the bust and hips.
What to wear, by clothing type
Common questions
How accurate is a body shape calculator?
It sorts your bust, waist and hip measurements into the five most common shapes using simple ratios. There is no universal standard, and different guides use slightly different cutoffs, so treat the result as a starting point for how clothes are likely to fit rather than a fixed label. If you are close to a boundary, the calculator tells you which neighbouring shape to read as well.
Does this calculator save or send my measurements?
No. The calculation runs in your browser and your measurements are never sent to a server or stored.
Can my body shape change?
Yes. Weight changes, pregnancy, hormones, age and training can all move your measurements. Re-measure every few years or whenever your clothes stop fitting the way they used to.
What if I fall between two shapes?
Many people do. When your measurements sit close to a cutoff, the result shows the neighbouring shape too. Read both guides and keep whichever advice fits how you like to dress.
Does this work for men?
The calculator compares bust (chest), waist and hips, and the outfit advice is written around women’s clothing cuts and sizes. Men’s shapes are usually classified by shoulders, waist and hips, so this tool is not built for that.
