Step 2: Decoration

(1) Select display type:

The app provides 3 different display styles for the size chart: Size chart button, Size chart block, and Floating button. When you click on each type, you can see its display preview, then choose the display type that matches the size chart and product for the best effect.

(2) Button setting:

  • Select a position for the button.
  • You also can change the position of the button by filling the distance you want on the input fields.

Step 3: Product to display size chart

You can choose to display the size chart for all products or only for specific products by searching for suitable products using the smart filter provided by this app.

You can add conditions to filter and easily search for products that match the conditions you want to apply a size chart.

Now, it’s time to choose a position to display the size chart. Click on the “Change position” button to open an instruction popup and follow the instructions.

Hover your mouse and choose the place you want on the product page.

Uninstall app

Installation of our Size Chart app automatically injects certain code snippets into your Shopify theme in order to make the installation process fully automatic and make our app work fast and smoothly.

Unfortunately, when you uninstall Size Chart, we lose programmatic access to your store, thus we cannot remove the code snippets that we injected automatically.

Although these code snippets that we add do not harm your store even after the uninstallation process, you might want to remove them anyway, the following guide will walk you through this process.

Step 1: Go to “Online store” in your Shopify Admin Panel > On your “Current theme” select “Actions” -> “Edit Code”


Step 2: In the “Assets” folder, delete the following files: “ets_sc_app.css”, “ets_sc_config.js”, “ets_sc_app.js”


Step 3: Delete all image files that have “ets_sc_” prefix.


Step 4: In the “Snippets” folder: delete file “ets_sc_assets.liquid”.

Step 5: In the “Layout” folder: open “theme.liquid” file then find and delete this line “{% include ‘ets_sc_assets’ %}”.
