True2Size: Chart & Recommender

True2Size adds a size recommendation widget to your Shopify product pages in minutes with no developer needed. Shoppers answer a quick questionnaire or enter their measurements to get instant size recommendations for each product. The widget shows confidence scores so customers know exactly how well each size fits their measurements. Merchants can upload size charts via CSV or manual entry and easily map them to products. Returning visitors get recommendations right away since their sizing profiles are automatically saved. Choose from multiple widget themes to match your store's brand colors, with support for six languages that auto-detect from the shopper's browser.
