How it works

From height and weight to one size.

Four steps, in the shopper’s browser, in a few seconds.

Step 1

Height and weight become a body.

Our body model, ShapeModel™, estimates bust or chest, waist, hips and more from height and weight. It is built on measured people, not guesses.

Height and weight typed in.
Step 2

The shopper corrects it.

The figure shows the estimate. One tap on − or + where it isn’t like them. A bra size or their own measurements work too.

The figure with bust, tummy and hips.
Step 3

Your chart decides the size.

We read your chart the way it is measured: body or garment, flat or all the way round, with the room each garment needs.

Step 4

One size, and how sure we are.

Many likely bodies are checked against every size. When most land on one, it’s a Strong match. When they split, we name the other size.

The result with fit lines.

Honest limits

What it doesn’t do.

No photos or body scans, no clothes on the figure. It can’t fix wrong numbers in a chart, so Test this chart before it goes live. The size finder is for adults.
