Body Shape Calculator

What this calculator does

This one is about proportions, not health. It takes four measurements and works out which of the classic body shapes your figure is closest to, using a system built for the clothing world. If you have ever read that a certain cut "suits an hourglass" or "works for a pear", this is the tool that tells you which label the tape measure lands you on.

A quick, upfront note, because it matters: the shapes here describe the female figure, and the system was designed for fitting clothes, not for judging health or looks. It is a styling aid, useful for shopping and tailoring, and nothing more. Below are the shapes it sorts into, how it decides, and how to measure yourself so the answer is accurate.

The seven body shapes

The tool compares your bust, waist and hips and places you in one of seven categories. In plain terms:

• Hourglass. Bust and hips are close in size, with a clearly narrower waist between them.
• Top hourglass. A balanced waist definition, but the bust is a little larger than the hips.
• Bottom hourglass. The same defined waist, but the hips are a little larger than the bust.
• Spoon. Hips noticeably larger than the bust, with a defined waist and a fuller upper-hip shelf.
• Triangle (or pear). Hips wider than the bust, with a softer waist definition.
• Inverted triangle. Bust or shoulders wider than the hips, tapering downward.
• Rectangle. Bust, waist and hips fairly close in size, a straighter up-and-down line.

None of these is better than another. They are just descriptions of how proportions are distributed, the same way clothes come in different cuts. The tool also gives you your waist-to-hip ratio alongside the shape, since it falls out of the same measurements.

How the calculator decides

Behind the label is a set of rules comparing your measurements to each other, drawn from a clothing-industry method called the Female Figure Identification Technique. It looks at things like how close your bust and hips are, how much narrower your waist is than each, and the shape of your upper hip. Depending on how those differences stack up, it assigns the closest shape.

Because real bodies are endlessly varied, the rules cannot cover every possibility. If your proportions do not fall cleanly into one of the seven, the tool will say so rather than force a label, which is the honest answer: some figures simply sit between categories.

How to take your measurements

All four go in as inches, and accurate tape work is what makes the result meaningful. Use a soft tape, keep it level, and do not pull it tight.

• Bust. Around the fullest part of your chest, tape level front and back.
• Waist. Around the narrowest part of your middle, usually just above the navel.
• High hip. Around the upper hip, over the top of the hip bones and the fullest part of the upper belly.
• Hips. Around the fullest part of your hips and buttocks.

Stand naturally, breathe normally, and measure over close-fitting clothing or bare skin rather than bulky layers.

What this is not

Worth saying plainly, because body tools can carry a lot of weight they should not. Your body shape here says nothing about your health, your fitness, or how you look. It is not a measure of anything to improve, and there is no "ideal" shape to aim for. It is a wardrobe tool, in the same spirit as knowing your shoe size.

The one number on this page that does connect to health is the waist-to-hip ratio it reports, and even that is only a rough screen. If you want to explore what your measurements might mean for your health, the Waist-to-Hip Ratio Calculator and Waist-to-Height Ratio Calculator cover that properly, with the evidence behind it. This page is for the fun, practical side: figuring out what cuts and styles tend to work with your proportions.

Questions people ask

How accurate is a body shape calculator?

It is only as accurate as your measurements, and even then it is placing you on the nearest label in a system that was never meant to be exact. Treat it as a useful starting point for styling, not a precise verdict. If your proportions sit between shapes, that is normal and the tool will tell you.

Does this work for men?

Not really. The seven shapes here describe the female figure specifically, so the categories and the rules behind them are built around female proportions. A men's version would use a different set of shapes entirely.

Can I change my body shape?

Your underlying frame, the width of your shoulders and hips and where you naturally carry weight, is mostly set by genetics and does not really change. Losing or gaining weight shifts your measurements, but your basic proportions tend to stay recognisable. The healthiest way to think about it is to dress for the shape you have rather than chase a different one.
