DerFit ‑ Size Recommender

Reduce returns with AI body scan size recommendations — the right fit, every time.

Sizing guesswork costs you sales and sends returns through the roof. DerFit fixes that at the source. Unlike simple size quizzes, DerFit uses a real AI body scan — your customers take 4 quick photos, and DerFit matches their real body measurements against your garment specs for a precise size recommendation at checkout. Not a guess. Real measurements, every time. Fewer wrong sizes, fewer returns, higher margins. Try DerFit free for 30 days.
