Top Shopify Size Chart Apps for 2026: Compared
Size chart apps are third-party add-ons for Shopify stores that guide shoppers toward the right size. They are especially useful for merchants selling clothing, footwear and other products where customers have to choose a size.
With these tools, merchants can build and customize size guides based on their own product specifications. Shoppers open the chart from the product page or a dedicated link, and clearer measurements mean fewer returns and exchanges caused by wrong sizes. Common capabilities include customizable templates, responsive layouts, several charts for one product, and multilingual support.
In short, a good size chart app improves the buying experience and can lift sales for online sellers.

Panda Size Chart lets you build a separate size chart for each product, so shoppers see exact measurements that match what they are buying. You can choose from several measurement units and shape each chart around your own requirements.
Because the charts are tailored, customers get sizing information that feels personal to them. The result is less time and money lost to returns, and happier buyers.

When shoppers are unsure about their size, they usually do one of two things: leave without buying, or order a size that turns out wrong and send it back. Avada helps them pick the right size from the start.
It cuts down on size-related return orders caused by missing information, reduces cart abandonment tied to sizing doubts, and lifts conversion on products that come in multiple sizes.

Guides attach to products through tags and can be edited or expanded to suit your store. If you sell through the Shop app, your size charts also appear there next to the matching products.

BF Size Charts presents clear charts for every size variation you carry. You simply pick the vendors, products, collections or tags a chart should apply to, then add your own text and images through custom text boxes.
