Key features and benefits

Simple to install with minimal code

We know how frustrating it can be to have to edit and hard-code size charts into your theme, so we’ve made creating a size guide as easy as possible. In order to tell the app where size guides should appear, you need just one line of code. Add this to your product page template and then you’re ready to create size guides! You can create a size chart using the table generator within the app. To add the guide to a product page, simply use product tags. Size guides can be easily edited and expanded.

Unlimited size guides

That’s right, create as many size guides as you need! It’s frustrating for a customer to have to scroll through a long page of size guides for different products. With Size Matters, you can create many size guides, and make it so that only the relevant guide shows on each product page.


It’s really easy to change the appearance and feel of the size charts so they look like an integral part of your Shopify store.

Aplicativo incrível, sem cobranças escondidas e um suporte fantástico. O time do aplicativo me ajudou acessando minha loja e fazendo a tradução do botão para minha loja. Recomendo demais o uso! Obrigado Louis, por fazer o ajuste em minha loja.
