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.

Great app. Small and minimalist and yet, so helpful. Doing exactly what I need. I needed some help and Louis was so patient, nice and very helpful. Hope you'll add more features in the future. Thank you, guys. Love it!

The Fresh Stuff

Outstanding support, clean and easy to use app and the result is so simple it’s perfect. You shouldn’t need a flashy size guide as it just makes things confusing and this does the job perfect... and it’s free.

Highly recommend you download and give it a try as now we can finally move size guides from our help page to dedicated product pages!

Victor's Surprise

I tried this app to help me add hassle free size charts to my products, but it's not clear as to how to do this, other than add tags that match, well I tried that and still no size chart even though I saved it.. it's nowhere to be found in my store. HUGE hassle.

It looks like you've pasted the code into the wrong place. Easily resolved, however! Please remember we have a support team for exactly these situations, but they can only help you if you contact them first.

They've sent you an email. Just respond to their message and they'll get the size charts sorted for you, hassle free. Once it's sorted, if you could update your review to reflect that, it would be wonderful.

Kind regards
