Hi @Rising Flight ,

Thank you for posting in this community.

You want to change the font size for an entire specific SharePoint site (similar to changing the theme of a site, not for a specific page), right?

Normally, you can use custom CSS to change the font size on a specific SharePoint site(This extensibility option is only available for classic SharePoint experiences. If you're using modern experiences in SharePoint Online, you can't use this option).

In summary: If you are using the modern experience in SharePoint Online, there is no way to change the font size for a specific SharePoint site.

As a workaround, Browser Zoom Feature: If you need a quick and temporary solution, you can use your browser's zoom feature to increase the font size. Press Ctrl + (or Cmd + on Mac) to zoom in.
