About
Easysize is an AI-powered clothing size and fit recommendation solution designed to eliminate the guesswork of online fashion shopping. At its core is the Fit Quiz — a lightweight, brandable widget that asks shoppers a few simple preference-based questions and instantly recommends the right size for any garment, including clothing and shoes, sportswear, and swimwear. The platform integrates natively with Shopify and Shopify Plus, and also supports custom e-commerce platforms via a flexible API. Fit Quiz is multilingual, detecting a shop's primary language and localizing into 11+ languages, while supporting all major international size formats (UK, EU, US, custom). It handles unisex products and can be extended with custom recommendation logic for additional attributes like fit, width, and length. Easysize is trusted by forward-thinking fashion brands worldwide and delivers measurable results: customers report up to 187% improvements in conversion rates, significantly fewer returns, and reduced customer service inquiries. Beyond business impact, Easysize champions sustainability by helping shoppers buy items that fit well the first time — reducing the environmental cost of returns, which contribute millions of metric tons of CO₂ and billions of liters of wasted water annually. Easysize is ideal for DTC fashion brands, Shopify merchants, and e-commerce retailers looking to improve the shopping experience, increase confidence at checkout, and build a data-driven understanding of their customers' preferences.
