Same size. Different measurements.

Two tops, both size M: the smallest and the largest we hold. The larger chest is 27% wider.

Both bars to one scale, the same dimension taken the same way. How we measure

How often the tag is wrong

80%

of almost 4,000 sizes of pants, jeans and shorts measure bigger than the waist on their tag.

A few garments, by the tape

Every figure below is a measurement of the garment itself, with the dimension named beside it. The rule drawn across each photograph is an annotation, not a measurement of the image.

The bars are an illustration with made-up figures. How much room a garment should leave depends on the garment. How we measure

What makes a good fit

Room, in the right places, in the right amount.

Where a top is judged: chest and shoulders first, then sleeve and lengthWhere pants are judged: the waist first, then inseam, thigh and seat

The right places

Tops are judged on the chest and shoulders, then sleeve and length. Pants on the waist, then inseam, thigh and hips.

The right amount of room

Too little pulls, too much hangs. How much is right depends on the garment: a tee wants less than a jacket.

The real measurements

We compare your measurements with the garment’s own, not with what its size chart promises.

Hemwise’s fit algorithm

Hemwise’s proprietary fit algorithm weighs each difference it can measure between you and the garment by how much it matters for that kind of garment, and turns them into one fit estimate per size, and says where it is snug, fits or roomy.
