Ensuring Clean Size Charts Work with Multilingual Apps

Many merchants use translation apps (Shopify Adapt & Translate, Transcy, T Labs, etc.) to serve shoppers in multiple languages. However, these apps can sometimes alter your product handle (the part of the product URL) for each language. Because Clean Size Charts often identifies products by their handle, this can break the link between product pages and their size charts.

The easiest solution is to use product tags—tags do not change when handles change, ensuring the correct size charts display for every language.

1. Why Product Handles Cause Issues

By default, Clean Size Charts retrieves a product by its handle (e.g., “tshirt-blue”). If a translation app localizes this handle (e.g., “camiseta-azul”), Clean Size Charts cannot find the matching product. Tags remain consistent across translations, which is what makes them ideal.

2. The Tag Method – How It Solves the Problem

  • Tags: A product tag stays the same whether a product handle changes or not.
  • Consistency: Apply one tag to your product in Shopify, and Clean Size Charts can reference that tag regardless of language.
  • Easy Setup: Just add the same tag in Shopify (under Product Organization) and Clean Size Charts.

3. Step-by-Step Setup

Below is the common workflow: Tag your products first in Shopify, then add the matching tag in Clean Size Charts.

Step 1: Tag Your Product(s) in Shopify

  1. Sign in to your Shopify Admin.
  2. Go to Products in the left-hand navigation.
  3. Select the product needing a size chart.
  4. Within the product details, locate the “Product Organization” section
  5. In the Tags field, enter a clear, descriptive tag (e.g., size-chart-tshirt ).
  6. Press Enter or Add to confirm, then Save at the top of the screen.

Step 2: Enter the Tag in Clean Size Charts

  1. From your Shopify Admin, go to Apps → Clean Size Charts.
  2. Choose the chart from your dashboard.
  3. Click Products to find your product assignment options.
  4. Find Show on Products that are tagged with
  5. Add the exact tag you used in Shopify (e.g., size-chart-tshirt ).
  6. Save your changes.

Step 3: Verify on the Storefront

  1. Switch your storefront to each supported language.
  2. Navigate to the tagged product page.
  3. Locate the size chart trigger (e.g., “Size Chart” button) and open it.
  4. Ensure the correct size chart appears in every language.

If not:

  • Double-check the tag spelling/capitalization (they are case sensitive).
  • Make sure you’ve saved the product after tagging it.

4. Frequently Asked Questions

Q1: Do I need to add tag for every language?

No. In most setups, adding the tag once in the product record is all you need. Translators typically mirror that data across languages.

Q2: Can I assign multiple tags if a product has different size charts?

No. Clean Size Charts supports one size chart per product.

Q3: Are these tags visible on the storefront?

Generally no. Most themes and apps keep tags hidden from customers unless specifically configured to show them.

5. Best Practices

  1. Keep Tags Consistent: Use concise, descriptive tags like size-chart-jeans  or size-chart-sweater .
  2. Bulk Updates: If you have a large product catalog, consider using Shopify bulk editing or dedicated tagging apps.
  3. Use a Naming System: If you plan multiple charts, create a naming convention you can easily remember.
