Choosing the right size is one of the biggest challenges for customers shopping online. This is especially true for clothing, footwear, jewelry, and other products where fit matters.
A good Shopify size chart app can make sizing information easier to understand, help customers choose the right variant, and potentially reduce fit-related returns.
But with so many apps available, which one should you choose?
We compared some of the leading Shopify size chart apps based on their current features, pricing, Shopify ratings, and available plans.

What Should You Look for in a Shopify Size Chart App?
The best size chart app depends on your products and how much control you need.
1. Easy Customization
Your size chart should look like part of your store rather than an unrelated widget. Look for customization options for colors, fonts, layouts, images, and buttons.
2. Mobile-Friendly Design
Size charts need to work well on phones. Customers should be able to open the guide, read measurements, and return to the product without struggling with the interface.
3. Size Recommendations
A traditional size chart answers "What are the measurements?"
A size recommender can answer the more important question:
"Which size should I buy?"
This can be particularly useful for apparel and footwear stores.
4. Easy Product Assignment
If you have hundreds of products, manually assigning individual charts can become time-consuming. Collection-based rules and automatic product assignment can make managing charts much easier.
5. Unit Conversion
International shoppers may be more familiar with inches or centimeters depending on where they live. Automatic conversion makes your size guides easier to understand for a global audience.
6. Import Options
If you already have size charts from another app or spreadsheet, CSV and other import options can save considerable setup time.
7. Multiple Display Options
Inline charts, popups, and floating buttons give you flexibility over where sizing information appears on your product pages.
Which Shopify Size Chart App Should You Choose?
There isn't one perfect app for every Shopify store.
If your priority is getting a full-featured size chart solution without paying a monthly fee, DEVNZO Size Chart & Size Guide is one of the strongest options to consider. It combines unlimited published charts with templates, customization, smart recommendations, unit conversion, and multiple display options. (Shopify App Store)
If you want an established app with a large review history and advanced importing and recommendation features, Kiwi is worth considering. (Shopify App Store)
MP is another strong choice for merchants who want a large template library, CSV imports, AI size recommendations, and a proven Shopify app. (Shopify App Store)
Jotly and BF are worth considering for stores looking for simpler and more focused size chart experiences, while CSC is particularly interesting for merchants who want AI-powered sizing capabilities. (Shopify App Store)
Final Thoughts
A size chart should do more than display a table of measurements. It should help customers understand your products, choose the right size, and feel confident before purchasing.
For Shopify merchants, the right size chart app can provide everything from a simple measurement table to a complete sizing experience with templates, recommendations, automatic conversions, product targeting, and customization.
If you're looking for a free and customizable starting point, DEVNZO Size Chart & Size Guide is worth trying first. For merchants with more advanced requirements, Kiwi, MP, Jotly, BF, and CSC provide several strong alternatives depending on your store's needs.
The most important thing is to choose an app that makes sizing simpler for your customers and easier for you to manage.
