Almost all business applications have horizontal menus and ribbons that take up a decent percentage of a landscape monitor instead of utilising the “spare” screen space on the left or right, and a taskbar usually sits at the bottom or top of the screen eating up even more space (yes I know this can be changed but it’s not the default).
Documents are traditionally printed/read in portrait which is reflected on digital documents.
Programmers often rotate their screens to be portrait in order to see more of the code.
Most web pages rarely seem to make use of horizontal real estate, and scrolling is almost universally vertical. Even phones are utilised in portrait for the vast majority of time, and many web pages are designed for mobile first.
Beyond media consumption and production, it feels like the most commonly used workplace productivity apps are less useful in landscape mode. So why aren’t more office-based computer screens giant squares instead of horizontal rectangles?
No, that’s when you just accept that there is additional space available to you for when (not if, WHEN) it becomes necessary.
Just because you don’t need it 100% of the time, doesn’t mean you shouldn’t have it for when you do.
This makes no sense at all. UIs are justified in not making full use of a widescreen monitor because at some point someone might want to use another at the same time?
UIs are justified in not pointlessly expanding into space they have 0 use for; leaving it available for other actually useful applications.
When I go to the buffet, I take what I’m actually going to eat, leaving what I don’t need for others; I don’t just empty the table into a bag knowing full well I won’t eat it all.
