Shopify size chart: size guide in CRO Toolbox
A size chart app shows a size table on product pages, often with a size finder, so shoppers pick the right size and send fewer returns. CRO Toolbox has it as size guide: size charts and a size finder on the product page. The finder asks the questions you pick and answers only from your own ranges and sizes. It is on the Starter plan and above, in the same app as upsells, bundles, a loyalty program and a Track order page.
