The **Icona Size Chart** theme app block adds the **Size chart** button to your storefront. The block works only on product templates.

## Check status from the app

Open **Size Charts** in the app and find the setup banner. It shows:

- Your **Current plan**.
- Your published chart count, shown as “N of N size charts published”.
- A **Size chart status** badge with **Active** or **Inactive**.

If the status is **Inactive**, click **Activate**. Icona opens the theme editor with the block already added to your product template. Click **Save** in the theme editor to activate it.

## Add the block manually

You can also add the block yourself or add it to a different theme:

1. In Shopify admin, go to **Online Store → Themes**, then click **Customize** for the theme you want to edit.
2. Switch the editor to a product template.
3. Click **Add block**, then choose **Apps → Icona Size Chart**.
4. Click **Save**.

## Change the button label

In the block settings, open **Button → Label**. The default label is “Size chart”. You can replace it with wording that suits your store.

## Next step

The block shows a button only when a product has a published chart. Next, [create your first chart](https://docs.tryicona.com/size-chart/getting-started/create-first-chart/) and assign it to a product or collection.
