The quick way is the default windows zoom Ctrl + Mouse wheel or use the zoom tool in your browser
What—you can
zoom in and out with Ctrl+mouse wheel?? Wow, whaddaya know! Okay, I'm being ironic. Though I've been on
this forum only since October, I've been using PCs (and occasionally Macs, sorry) since
pre-mouse days. So yes, I know about the mouse-wheel-zooming thing, but thanks for making me feel young again for a moment!
With the increased use of high res [especially 4K] and it's use on smaller screens the default size is intentionally larger than some sites but it's as always a compromise and has user control
As far as I know, the only real distinction site developers must make is whether it's a mobile display or not—and if it is, to make their text big enough so it's legible even on a phone-size display.
On HD(+) displays, text is usually too
small at 100% DPI, so the user needs to adjust their OS's DPI scaling. But when text is too
big, it usually means (a.) you're inadvertently viewing the page at more than 100% browser zoom; or (b.) the site's creators opted for a larger-than-usual point size.
In other words, I've never heard of anyone saying, "Gee, displays are getting awfully high-res these days... Maybe we'd better make the text on our [non-mobile-version] webpages bigger." It's how
close we have to get to the pages that's changed, if you will.
DISCLAIMER: I'm saying all this entirely good-naturedly, as we like to chatter about computer stuff here. I love this excellent site and am grateful to be on it. I was a regular on tenforum.com, and eightforum.com before that, and sevenforum... I'm guessing they were related. And really, I don't mind the big text here at all; I was just curious. Okay, that's about it. Cheers, A.
