Different windows have different good sizes.<p>For example, I don&#x27;t run my browser maximized, because I don&#x27;t want web pages in landscape; acres of margin or very long lines - neither choice is good. The viewport of my browser is nearly square (1500 x 1300).<p>Terminals don&#x27;t work great with very long lines either; man, less etc. adjust to terminal width making lines harder to read.<p>My scratchpad app I keep for notes is generally notepad shaped, i.e. taller than it is wide, but not as wide as a terminal window.<p>My password manager (KeePass2) is the only other really common app. I don&#x27;t interact with it very often other than via hotkey.<p>I keep Emacs&#x2F;IDE maximized on a different screen.
