Can I change the font used in the Size Chart? – Light-Tech

The font used in the Size Chart app is automatically inherited from your site's styles — manual font selection is not available.

In Wix Studio, the app always uses the P2 text style. It applies both to the button and the content inside the popup.
In Wix Editor, the button inherits the same font style as the “Add to Cart” buttons. The content inside the popup, however, uses a default font that cannot be changed.

To modify the appearance, adjust your site's theme text styles accordingly.
