Not to mention most websites love to waste vertical space. Navbars keep getting thicker, designers insist on having top bars even when the navigation is in the sidebar and the bottom is eaten up by cookie banners and chat/feedback popups.
I’m guessing the problem there is that mobile is far more unforgiving on horizontal space than laptops are on vertical space, so anybody building a webpage to target both ends up in the regime you’re talking about.
