Hello njuelsgaard
No, not to the frame. When entering a page it will automatically zoom so all content on the page will fit to the screen, but this does not count the frame around as a "content". This is the same as when using the Home key on the keyboard to zoom "Fit page".
However, if there are no items at all inside the page, it will zoom to the page frame when entering, but I would guess you normally have something in the page.
The zooms available are found in under View --> Zoom. There are also some settings available for Zoom in Setup --> Options.
Best regards
