Two photos become a fit answer in seconds
Thinx3D rebuilds a shopper's body shape from front and side phone photos, then compares it with graded garment measurements to forecast the item's fit.
Three steps to a confident size
In 60 seconds, shoppers get fit guidance and you get returns driven by fit, not guesswork.
Front and side, standing naturally. No special hardware, lighting, app, or equipment needed, only the phone in their pocket.
Photogrammetry reads silhouette, shadow, and pose depth cues to form a parametric 3D model calibrated against real body dimensions.
We compare each measurement with your graded specs across sizes, then show the best match on the product page with a clear explanation.
Inside the fit engine
Every Thinx3D pipeline phase targets accuracy at the point where fit judgments typically fail.
Photos become clean body silhouettes
A lightweight widget on your product page accepts two shopper photos. Our pipeline removes background noise with a segmentation model trained across diverse body types, producing clean silhouettes for modeling.
Parametric body model reconstruction
Contours from both views enter constrained optimization, fitting a parametric 3D body model to the observed outlines. It delivers circumference and length measurements accurate within 1.8 cm across key fit zones, validated against a corpus of 3D body scans.
Comparing specs and recommending a size
We test the shopper's measurements against your graded garment specs at every available size. A score balancing relaxed or fitted preferences with ease allowances selects the best fit, then displays it with a zone-by-zone breakdown.
Measurements built for real bodies
Thinx3D was tested against 600 participants spanning body type, ethnicity, age, and clothing condition. These figures come from validation, not selected demos.
Fewer size mistakes, fewer returns
Guessing a size creates a consistent return pattern. Shoppers using Thinx3D guidance return at about half the rate of shoppers choosing without fit help. The dashboard shows a representative early-access brand partner before-and-after.
The gains build: fewer returns cut reverse-logistics expense, lift net revenue per order, and make repeat purchases more likely among first-time buyers.
