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.

Works as advertised, had one small modification to make and support helped me pretty fast.
it does make you wonder though why the option isn't in the app to begin with, also please implement image, looks so much cooler.
since it works as advertised and support is good 5/5 no BS.

The app is good and easy to use. The customer support though took over 3 days to respond then another 4 to respond again.... But you know what you guys clutched up in the end.

Thanks for the review - sorry there was a delay in the response time on this occasion. Although it's one of our free apps, the customer service is not reduced because of this. Our support team work Monday to Friday, and this past weekend was a holiday weekend in the UK which may have contributed to the delay. We hope you continue to be happy with the app!
