“Honestly one of the best apps I've added to my store. Clean Size Charts does exactly what it promises — the charts look polished, integrate seamlessly into the product page, and the customization options are flexible enough to match my store's design without any custom code. What really stands out, though, is the support. Zachary and the team responded within hours, helped me set everything up correctly, and even followed up to make sure the charts were displaying properly across all my products. That kind of hands-on attention is rare. Highly recommended for any fashion or apparel store. Worth every penny.”

“The support team was very responsive and assisted with my dev needs, which led me to upgrade the app. With my multi-vendor site, this app has been great for easily dropping in tables—much faster than previous apps that required importing and exporting CSV files. Working with a smaller team, this app made it much easier to create size charts with minimal lift.”

“I tried a few size chart apps before settling with Clean Size, it's easy to use and configure, also has great features to make the size chart look good. Integration work best when I added the custom liquid on my store, this process was easy as the code was supplied, you just had to copy and paste.”
