TagFit Size Charts for POD

Setup guide

Get an accurate size guide button on every Printify product page in three steps. No theme code required — the setup takes about two minutes.

1

Add the app block to your theme (one time)

Open your Shopify Theme Editor, navigate to a product page template, and add the Size chart (POD) block from the Apps section. You only need to do this once — it applies to all products automatically.

  1. Go to Shopify Admin → Online Store → Themes → Customize
  2. In the page dropdown at the top, select Products → Default product
  3. Click Add block in the left sidebar, open the Apps section
  4. Click Size chart (POD) to add it
  5. Click Save

The Size chart (POD) block appears under Apps in the theme editor.

Tip: You can drag the block up or down in the sidebar to control where the size guide button appears relative to other product page elements (e.g. below the Add to Cart button).
2

Find your product's tag in the app dashboard

Open the app dashboard and search for your product. Each product has a unique tag — copy it with the copy button.

  1. Open TagFit Size Charts for POD from your Shopify Admin → Apps
  2. Use the search box to find your Printify product by name or brand
  3. Click the copy icon next to the tag (e.g. sizechart-gildan-unisex-softstyle-t-shirt)

Search your product, then click Copy next to its tag.

3

Paste the tag on your Shopify product

Tags are how the app connects a product to its size chart. Paste the tag you copied in Step 2 onto the product in your Shopify admin.

  1. Go to Shopify Admin → Products
  2. Open the product
  3. Scroll down to Tags and paste the tag
  4. Click Save

That’s it. The size guide button will appear on the product page immediately. Repeat Step 3 for each product — no theme changes needed again.
