How to Set up Sizechart Metafield
By default, the Sizechart image will display the same for all products. But you can create a dynamic size chart for your products using Shopify metafields. This allows you to use one product template for multiple products while displaying different size charts for each product.
Notes:
- Using metafields allows flexibility—you don’t need a separate template for each product.
- Customers can see the relevant size chart automatically.

You can follow the following steps to do that.
Step 1. Turn on the Sizechart metafield by choosing Image metafield in the dropdown. Now, you need to fill in the Metafield value to the box.

Step 2: Go to Shopify Admin -> Setings

Click Metafields and metaobjects -> Products

Step 3: Then Add definition

Put a name for this new metafield -> choose type Image (file) then copy the metafield code:
custom.size_chart_image
Step 4. Navigate to Products -> Edit a specific product -> Uploading an image of sizechart ( png, jpg, webp,..)

Step 5. Finally, you go back to the App Editor -> fill in metafield value to the box. The final code should be:
product.metafields.custom.size_chart_image
As a result, the Sizechart image is showing up when you click to Sizechart button on the product single page.

Repeat step 4 to add more different sizechart images to other products.
