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.

costumer service of this app is super great!!!! The app works perfectly and i am very happy with it!


Definitely deserve a 5 star rating. I had this app working on a free theme, and I paid for a theme on my store, but realized afterward I couldn't get the Size Matters app working without some help, I contacted makers of my $180 theme, and I contacted Eastside Co who made this Free App. The theme makers never got back to me, however, Louis from Eastside Co did get back to me, and was more than willing to help. He got me to add them as a temporary Staff member, and coded it into the theme for me, without asking for anything, the coding was flawless, and it looks excellent on the store, just in time for my stores Monday launch, Props to Eastside Co, You guys are life savers.

What an app! It is exactly what I needed.
Also, the support service was the best I have received on shopify so far. Even better than the shopify

Please stick to this excellent support service
