How we compared them

On 19 October 2026 we searched the Shopify App Store for “size chart” and “size guide” and took the nine dedicated size chart apps with the most reviews. We added Pify because it ranked first for “size chart”. We left out product options apps that also draw charts. Figures come from each public listing; we did not install the apps for this comparison. Some apps list further plans on their own websites, which are not included here. Ratings and prices change, so check the listing before you install.

One of the oldest apps, launched in 2016 by Eastside Co. It is a simple chart builder: 3 watermarked charts free, or unlimited charts for $4.99 a month, assigned by tag, collection, vendor or product type. The listing shows a 3.3 rating from 140 reviews.

Launched in January 2026 and rated 5.0 from 49 reviews. The free plan of 2 charts includes a size recommender. Premium, at $29.99 a month plus order-based usage fees, bundles upsells, a sticky add-to-cart and swatches, so it is more than a chart app.

Free, with no paid plans shown, rated 5.0 from 42 reviews. It shows size information when a shopper hovers over a size option, and supports tables, images, tabs and cm/inch conversion.

A chart app or a size recommender?

A chart answers “what are the measurements?” and leaves the shopper to measure themselves and choose. A recommender answers “which size should I buy?”. Most of the apps above started as chart builders and added recommendations later, usually on paid plans with monthly limits.

Check where the chart appears, too. Several apps draw the chart in the browser after the page loads, so it is not in the page HTML. In our scan of 829 Shopify clothing stores, 7.7% showed their chart only through a sizing app’s script. Our free size chart audit shows what your product pages publish.

Where Rendered Fits fits

Rendered Fits is not a cheap chart builder, and if you only need a chart, one of the apps above will cost you far less. It is built for brands where the size decision is the problem. It recommends a size for the exact product from that product’s own size chart and the shopper’s fit profile, reuses the profile across products, sizes Complete the Look outfits and offers try-on as a preview of how an item might look.

It is free on one product. Complete is $349 per month with a 14-day trial, and Enterprise is $999 per month. Both paid plans include a try-on allowance with optional extras, and there are no sales-based fees. See current plans.
