Fit, measured

Find clothes that fit like the ones you already love

You already own something that fits you perfectly. Photograph it flat with a bank card beside it. The card is a known size, so it works as a ruler. GarmentDNA measures the garment from that photo, then compares it against any shop's size chart to tell you which size to order.

Completely free. No account, no payment, nothing to sign up for.
No body scanning. No tape measure. No guessing between M and L.

How it works

One photo. A bank card. That's the whole setup.

01

Lay it flat, add a card

Lay your favorite shirt on any plain surface and place a bank card beside it. Every card on earth is exactly 85.6 × 54 mm. It's the ruler in the photo.

02

Snap one photo

Computer vision finds the card, corrects the camera angle, traces the garment, and extracts chest, length, shoulder, sleeve, and hem, to the millimetre.

03

Shop anywhere

Paste any product's size chart (or link) and get a plain-language verdict: "Size M, 95% match. Chest 0.8 cm roomier, length identical."

The long game

The GitHub for clothing fit

Every garment scanned creates a structured fit profile. Together they become the world's largest database of how clothes actually fit, not how retailers' inconsistent size charts claim they do. That data unlocks an ecosystem.

01

Retailer APIs

"Will this fit customer X?" answered before checkout, on any storefront.

02

Affiliate commerce

Fit-verified buy links. Commission on purchases we made confident.

03

Resale marketplaces

Verified measurements on every secondhand listing. No more "fits like a medium?"

04

Wardrobe management

Your closet, digitized and searchable, with fit as the organizing principle.

05

AI shopping agents

Agents need ground truth about your fit. GarmentDNA is that ground truth layer.

06

Return reduction

Sizing drives ~52% of apparel returns. Retailers pay to make that number fall.

07

Fit data licensing

Brands designing new lines against real-world fit distributions, not guesses.

The thesis
Every scan makes the next recommendation smarter. The measurements are the product today. The database is the company tomorrow. GarmentDNA · 2026
