A size you know in another brand
The customer starts from what they already know — "M at Nike" — and PerfectFit translates it into your size chart. The fastest path to the right size.

The right size,

Three methods
The customer picks, the engine translates
Every customer has a different starting point. PerfectFit accepts all three and always returns the same thing: a recommended size, a fit score and cross-brand equivalences.
Their measurements in centimeters
Chest, waist, hips: the engine compares them to the real dimensions of your products and returns the exact size with a fit score.
A photo of a garment laid flat
AI extracts the measurements straight from a photo of a garment that fits the customer well. No manual entry.
How it works
From product page to the right size
1
The customer states their size
On your product page, the widget offers the three methods. The customer picks whichever is at hand — ten seconds is enough.
2
The engine computes the fit
PerfectFit normalizes the request, compares it to your chart dimensions and produces a recommended size with a readable compatibility score.
