Shopify Size Guide App
More than a static chart — an interactive size guide that recommends the right size and reduces returns.
A Shopify size guide does what a plain chart can't — it actively helps each shopper find the right size. Tailor Size Guide combines per-product size charts, an AI fit recommender, and made-to-measure capture in one app, so buyers stop guessing and you stop processing wrong-size returns. Install in minutes, no theme code required.

Size chart vs size guide: what's the difference?
A size chart is a table the shopper has to read and interpret. A size guide goes further — it can ask a few questions and recommend a size, show how to measure, and adapt to each product. Tailor Size Guide does both: the chart builds trust, the guide drives the decision.
- Interactive size charts per product
- AI fit recommender that suggests a size
- How-to-measure visuals for shoppers
- Inch/cm toggle and localization
A fit recommender that cuts the guesswork
The built-in fit recommender asks the shopper a few quick questions — height, weight, usual size, fit preference — and returns one clear recommendation. That removes the hesitation that loses sales and the guessing that causes returns, especially for first-time and gift buyers.
Made-to-measure and custom sizing built in
For tailored, bespoke, or made-to-order products, the size guide captures full customer measurements at the product or cart and ties them to the order. It's ideal for custom apparel brands that want to all but eliminate fit returns and charge a premium for a perfect fit.
- Capture measurements at checkout
- Measurement records tied to each order
- Perfect for made-to-order and bespoke
- Works alongside standard sized products
