Clean Size Charts (listed on the Shopify App Store as "CSC: Size Chart & Size Guide") is a size chart, AI size recommendation and virtual try-on app for Shopify apparel, footwear and accessories stores. Merchants build size charts from 18 garment templates or with AI, style them to match their theme, and assign them by product, collection, vendor, tag or product type. Charts appear on the product page with automatic inch and centimeter conversion, rules to show different charts by country, and support for multiple storefront languages. On the Plus plan, an AI size recommender asks shoppers a few questions and returns one recommended size, virtual try-on lets shoppers see a product on their own photo, Fit Notes flag when a style runs large or small, and fit analytics show how charts affect orders. Every plan includes done-for-you setup: the team builds the merchant's first size charts and migrates charts from other apps for free. Pricing: a free plan with two published charts, Grow at $6.99 per month for unlimited charts, and Plus from $29.99 to $299.99 per month based on monthly order volume. Paid plans include a 14-day free trial.
