Merch ‑ Size Chart Fit

Merch, officially listed on the Shopify App Store as Merch ‑ Size Chart Fit, is a Shopify app in the Product comparison category. Add clean size charts to apparel and footwear product pages, plus a "find my size" fit recommender that helps shoppers pick their size — no theme code. Build unlimited charts (table, text, or image); assign by product, collection, type, tag, or store-wide default; cm/in toggle; 15 languages with RTL; 39 ready-made templates. Go further with per-variant pre-select and CSV import/export. Privacy first: no shopper data, read products only, nothing written to your theme. No layout shift on load.

Merch offers a free plan and a single paid plan at $14/month. The free plan includes Unlimited size charts, Measurement, text & image charts, Assign by product, collection, type, tag, and cm/inch toggle, auto by region. The paid plan unlocks advanced features like additional integrations, automations, and deeper customization.

Merch does not currently carry Shopify's Built for Shopify badge. The badge is awarded to apps that meet Shopify's published standards for performance, ease of use, and merchant value — many high-quality apps operate without it.

Merchants commonly compare Merch with Globo Product Options, Variant, Easify Custom Product Options, Color Swatch King, and Infinite Product Options. Each alternative covers a similar use case but differs on pricing model, integration depth, and the specific themes merchants praise in reviews — see the alternatives section above for a side-by-side.
