Apparel shoppers on mobile often abandon a product page because sizing information is buried, inconsistent, or missing. FitBlocks lets you build size charts and fit guidance inside the Shopify admin, decide which products each block applies to, and publish to your storefront through the app embed without editing theme code. Your product pages then carry consistent sizing information in a mobile-first layout you control, and changes reach the storefront as soon as you publish.

• Build size charts with your own measurements, units, and notes
• Show fit guidance for items that run small, large, or true to size
• Add a floating size help button for mobile product pages
• Recommend matching products to encourage larger orders
• Choose the products each block appears on, or apply it to all
