    Shopify Size Chart

    Add interactive, per-product size charts to your Shopify store — and cut size-related returns.

    A Shopify size chart is the single fastest way to cut wrong-size returns and win buyer confidence. Tailor Size Guide adds interactive, per-product size charts to any Shopify store — as a popup, tab, or inline block — without touching your theme code. Build charts once, assign them by product or collection, and let shoppers find their size in seconds.

    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

    How to add a size chart to Shopify

    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.
