Fit is the real problem. Not size.

Size recommenders are essential for boosting conversions, building customer confidence, and increasing AOV. But they can’t fix a product that doesn’t fit well. If the fit is off, customers will return it. Even if they picked the right size. Brands that truly want to minimize returns at the core, need to start solving the problem where it started: at the product level.

SAIZ’s Fit Operating System helps you solve fit challenges from design to checkout. Our Data Tailoring System (DTS) analyzes real customer and product data to uncover fit patterns and turn them into clear, actionable insights. These insights power our easy-to-use Product-to-Person Platform (PTPS), helping your teams connect the dots between customer needs and product details to make smarter decisions.

Fewer returns, smarter sizing strategies, and stronger margins across your entire value chain.
