What merchants think

Feedback submitted

Merchants say this app is easy to set up, theme‑compatible, and great for creating clean, modern size charts that standardize sizing and make product pages more professional. Many report fewer sizing questions and returns, and some note better conversions. They like flexible customization, advanced options like multiple charts and a Fit Finder quiz, and frequently praise fast, proactive support. The free and paid plans are seen as good value.

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!

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!

I’m curious about the ‘compare button’ that you mention. I will get back to you per email.

We are also working on our new app also related to site recommendations. I will connect with you as we would love to have you as one of our pilot users!

Kind regards,

I would recommend Smart Size to others because it is easy to use, easy to install and expandable as needs increase. The free version is my first experience with sizing on the site, and it is a simple solution that works.

The application sometimes has technical issues wherein the size chart randomly disappears from the website.

However, the team is fast to react to such mishaps and get the issue resolved.

Thank you for your continuous support.

I had a really great experience with the SmartSize support team. They were incredibly responsive, understanding, and genuinely willing to help. I explained my situation, and they went above and beyond by offering a custom solution.

It’s rare to find such flexibility and customer-focused service, especially from a smaller team. You can really tell they care about their users and want to support their growth.

Highly recommended — both the app and the people behind it!
