Smart Size Chart & Size Guide

SmartSize is an absolute game-changer for my store! It’s incredibly easy to use and very beginner-friendly — I had my size charts set up in minutes without touching a single line of code. The pricing is super reasonable compared to other apps, making it perfect for new and growing stores. I also love how clean and professional the charts look on my product pages, giving my customers more confidence to order the right size. Honestly, it feels like a premium tool at an affordable price. Highly recommend SmartSize to anyone who wants a smooth, reliable, and stylish solution for size guides!

I was having issues with the Kiwi size chart, and after being ignored by their customer support for almost 2 months, I'd had enough. That's when I came across Smart Size.

My one criterion was that I needed to embed a video guide showing the sizes. Based on all the size chart apps I emailed to ask about this, Smart Size was the only one that replied, agreeing to customise the app for my liking.

Helen from customer support was an absolute gem! Solved my issues quickly and now my charts look exactly how I want them to.

I would highly recommend this app to anyone looking for a free size chart for their store with great customer support.

I was struggling to style the Smartsize table to match my brand’s look, and after hours of CSS tweaks and dev help from AI that got me nowhere, Helen stepped in and got it working perfectly in minutes. Headers styled, spacing sorted, toggle aligned and everything I needed. Seriously impressed by the responsiveness and the fact that they nailed it. Highly recommend if you care about detail and clean design.

I would like to recommend this APP that is helping us to instruct the customers about products size. It helped us to reduce the rate of change.
We appreciated a lot also the customer assistance and the team that updated the forms and colors of the tabs and charts according to our wishes.
Top.

I just started using this App. Until now I have been copying size charts from the supplier and loading as images. It is not as professional as I wanted. Smart Size Charts offers so much functionality to standardise, create individual charts for one or more products and to manage the info to sort your brand. I had one issue with edging on a chart. I mentioned it to support. Helen asked me to give her access and added some CSS code and all was perfect. Loving the App so far and really making my site look so much more professional after spending time to upgrade everything. If you are looking for a great size chart App. This is it!

I’ve been using SmartSize - Size Guide for a few weeks now, and I’m really impressed! It’s made a huge difference for our customers by providing them with a clear and accurate size guide. This has helped reduce sizing mistakes and made our customers much happier overall.
Thank you!

Smart Size Chart & Size Guide has been a real game changer for our business. The process to setup charts + guides was not only extremely easy but looked absolutely amazing. The ability to change between in/cm, add measuring notes + images and the ability to clone size guides made it a very fast and accurate way to display information.
Our questions were answered promptly and the team was willing to assist not matter the question. You won't regret using this APP!

I love using this app! It's great. My customers love it. I've used a few different apps like this and this is the one I decided to stick with. It works well and has everything I need.

The app developers are super lovely and helped me out when I needed help with a setting that I missed while setting up. They are also super happy to receive any feedback to make the app even better, which I always appreciate. Highly recommend!

One of the best apps in this segment, without a doubt!
Great compatibility with Shopify and fantastic support that is extremely dedicated to understanding and helping with users' needs.
The SmartSize app is highly intuitive and user-friendly, offering several customization options while maintaining a very professional appearance.
Thank you, SmartSize Team — especially Helen — for your dedication and commitment to continuously improving the app!

Great app - reasonably priced. Automatic size conversion works well and the customization of text and images along with the chart helps explain sizing better. The new tabs feature is great - we can offer sizing by different fit (tall, trim, regular...) in one master product and customers can easily toggle between the different size charts to see differences in fit. Maybe one day they could come up with a compare button between two tabs to see how it might fit differently? The support team is great, too!
