Three measurements

Body shape calculator

Measure your bust, waist and hips, and this works out which of the five shapes those numbers describe, and what it means for what you wear underneath.

Measure in
Around the fullest part, tape level.
At its narrowest, snug and level, breathing out.
At the widest part, usually across the fullest part of your seat.

The five shapes, and how each one is worked out

  • Hourglass

    Bust and hips within 2 inches of each other, and a waist at least 9 inches under the bust or 10 inches under the hips.

    Bust and hips in line with each other, and a waist that dips well below both. Clothes tend to fit one measurement and hang loose at the waist.

  • Pear

    Hips more than 2 inches wider than the bust. Also called a triangle.

    Hips wider than the bust, with the difference sitting at the seat and thigh. Skirts and trousers usually decide the size.

  • Inverted triangle

    Bust more than 2 inches wider than the hips.

    Bust and shoulders wider than the hips, so tops run out of room before anything below the waist does.

  • Apple

    Waist within 4 inches of both the bust and the hips, with no clearly narrower waist. Also called round.

    Bust, waist and hips within a few inches of each other, with the weight carried around the middle. Waistbands are the thing that has to be right.

  • Rectangle

    Bust and hips within 2 inches of each other, and a waist narrower than both by more than 4 inches but short of the 9 or 10 an hourglass needs. Also called straight.

    Bust, waist and hips close in measurement, with a waist that is narrower but not sharply so. Clothes hang straight rather than following a curve.

The rules are checked in the order above, and the first one that fits is the answer. Everything is compared in inches, so centimetre entries are converted first. Other calculators draw these lines in slightly different places, which is why a set of measurements sitting near a boundary can come back with a different word elsewhere.

Three measurements

How to measure for this

01
Bust
Tape across the fullest part, level front to back, resting rather than pulling. Wear a soft unpadded bra or nothing at all. Pulling the tape tight here is the most common reason a shape comes out wrong.
02
Waist
Find the narrowest part of your middle, usually an inch or so above the navel, and keep the tape snug and level while you breathe out. Holding your stomach in changes the answer and nothing else.
03
Hip
Stand with your feet together and tape the widest part, usually across the fullest part of your seat, level from front to back. On most people this is the largest of the three numbers.
Questions people ask

Body shape questions

How do I check my body shape type?

Measure your bust at the fullest part, your waist at the narrowest and your hips at the widest, then compare the three. Bust and hips within two inches of each other with a waist nine or ten inches smaller is an hourglass. Hips wider than the bust is a pear, a bust wider than the hips is an inverted triangle, and a waist within four inches of both is an apple. What is left over is a rectangle.

What is a 34-28-36 body shape?

A rectangle by the rules on this page. The hips are two inches wider than the bust, which still counts as balanced, and the waist is six inches under the bust and eight under the hips, short of the nine and ten that mark a defined waist. It sits close to both the hourglass line and the pear line, which is a fair illustration of how little separates one shape from the next.

What body shape is 33 26 36?

A pear. The hips are three inches wider than the bust, past the two inch line, and the waist is ten inches under the hips. Some calculators call this a bottom hourglass because of that waist, but the shaping advice is the same either way: the work is at the hip and thigh.

Is the 36 24 36 body shape real?

As a set of measurements, yes, and every calculator including this one reads it as an hourglass. It is also uncommon, and it has been repeated as an ideal for so long that it stopped describing anybody in particular. Three numbers say nothing about health or height. Measure your own and use them to buy clothes that fit.

Can my body shape change?

Yes. Weight, pregnancy, muscle and age all move the three measurements, and the shape moves with them. Measure again when clothes start fitting differently rather than working from numbers you wrote down years ago.

Which size shapewear goes with my shape?

Your shape decides which garment, and your measurements decide which size of it. The shapewear size finder takes your waist and hip and gives you a size in each shaper we stock, including the case where your measurements sit outside the sizes we carry.
