Running an online store comes with its own set of challenges, and one of the most common is dealing with returns due to sizing issues. For clothing and apparel brands, creating a clear and accessible size chart can significantly reduce these returns. Luckily, tools like a size chart metafield for Shopify exist to help store owners manage and display size charts effectively.
What Is A Size Chart Metafield for Shopify?

Shopify metafields are custom fields that allow you to store additional information on your products, collections, customers, and orders. They’re incredibly flexible and can be used for a wide range of purposes. Whether you want to add extra product details, custom descriptions, or in this case, size charts, metafields give you the freedom to customize your store’s data. However, you will need to know some code in order to get them to work!
Why Use Shopify Metafields for Size Charts?
Shopify metafields offer a flexible, easy-to-manage solution for creating and displaying size charts in your store. By using Shopify metafields for size charts, you can:
- Reduce Returns: Clear size charts help customers pick the right size, reducing the likelihood of returns and exchanges.
- Customize the Shopping Experience: With dynamic size charts, customers can easily find the most relevant sizing information for each product, improving their overall shopping experience.
- Save Time: Metafields allow you to manage size charts across your store efficiently. Once the metafields are set up, you can easily update or change them without having to manually edit each product page.
How Do You Add a Size Chart in Shopify Metafields?
Adding a size chart in Shopify metafields is simpler than you might think. Here’s a step-by-step guide to help you integrate size charts using Shopify’s native metafields functionality:
Step 1: Access Shopify Metafields
First, log in to your Shopify admin dashboard. From the menu on the left, scroll down to “Settings.” Once in the Settings page, you’ll find a section labeled “Metafields.”
Step 2: Create a New Metafield Definition
Once you’re in the metafields section, click “Create definition.” You’ll need to create a new metafield definition for your size chart. In this case, you’ll want to select “Products” because size charts are usually tied to individual product pages.
After selecting “Products,” you’ll be prompted to define your metafield. Give it a name like “Size Chart” and choose the type of content you want to store. For size charts, the most common formats are “Rich text” or “File.” If you prefer to keep it simple, opt for a rich text field where you can input your size chart directly.
Step 3: Add Size Chart to Your Products
Once your metafield definition is created, you can now assign a size chart to each of your products. Go to the product page in your Shopify admin and scroll down to the new “Metafields” section. Here, you’ll see the “Size Chart” metafield that you just created. Input your size chart directly into this field or upload a file if that’s how you’re presenting your chart.
Step 4: Display the Size Chart on Your Product Page
To show the size chart on your product pages, you’ll need to edit your Shopify theme. Go to the “Online Store” section and click “Themes.” From there, click “Customize,” which will take you to the theme editor.
In the theme editor, navigate to the product page section where you’d like your size chart to appear. You will then insert code to display the size chart, which will automatically display on the product page for any product that has a size chart metafield assigned to it.
How Do You Add a Dynamic Size Chart in Shopify?
Adding a dynamic size chart can make your store even more user-friendly, as it allows you to tailor size charts to specific products or collections without having to manually input the data for each one. Shopify’s metafields offer a seamless way to achieve this… if you know how to code. Instead of assigning the same size chart across all products, you can make your size charts dynamic by using metafields. This means that each product can have its own specific size chart, displayed automatically when that product is viewed.
In your Shopify admin, go back to the metafields section and create different metafield definitions for each product type or collection. Label them clearly and input the size chart data accordingly. Then, edit your theme to pull dynamic data from metafields. The key difference here is using conditional logic to determine which size chart to display based on the product being viewed.
If that sounds complicated, don’t worry. There’s a much easier solution: integrating a third-party sizing app that does all the work for you!
