Why every Shopify store needs a size chart
Wrong size is the number-one reason apparel gets returned. A clear size chart on the product page removes the guesswork that drives returns and abandoned carts — and it's expected by shoppers. Without one, buyers either bounce or bracket-buy two sizes and send one back.
- Reduce size-related returns and exchanges
- Lift conversion by removing sizing doubt
- Look professional and build buyer trust
- Cut the 'what size am I?' support tickets
Per-product charts, not one store-wide table
Different products fit differently — a slim tee and a relaxed hoodie shouldn't share a chart. Tailor Size Guide lets you assign the right size chart to each product or collection, so every page shows the measurements that actually apply. Add an inch/cm toggle so every shopper reads it their way.
Popup, tab, or inline — your choice
Show the size chart however fits your theme: a 'Size guide' button that opens a popup, a product-page tab, or an inline table below the variants. All three are mobile-first and load fast, so they don't hurt page speed during peak traffic.
- Popup size chart triggered from a button
- Product-page tab next to description and shipping
- Inline table for always-visible sizing
- Optional fit recommender to suggest a size

Frequently asked questions
How do I add a size chart in Shopify?
The easiest way is a size chart app like Tailor Size Guide: install it, build or import your chart, assign it to products or collections, and choose a popup, tab, or inline display. No theme code is required. You can also use metafields with theme code, but that needs a developer.
Can I show a different size chart for each product?
Yes. Tailor Size Guide assigns charts per product, collection, or tag, so a slim tee and a relaxed hoodie each show their own measurements instead of one store-wide table.
Will a size chart slow down my Shopify store?
No. The charts are lightweight and load on demand, so they don't hurt page speed — important during high-traffic sales when conversion matters most.
Is there a free way to add a Shopify size chart?
Yes. Tailor Size Guide has a free plan that covers basic charts. Advanced features like the AI fit recommender and made-to-order measurement capture are on paid plans.
Do size charts actually reduce returns?
Yes — wrong size is the top return reason for apparel, and a clear per-product chart (especially paired with a fit recommender) removes the guesswork that causes those returns.
