I get letters almost every day from grateful people who have found this blog about what to do when your screen font becomes teeny tiny, so I repost it every once in a while.
Somehow, the font on my screen had become so tiny I was hunched over my laptop to read it. Not good.
I reached out in frustration to my fellow guides at About, and learned that Ctrl + will increase the size. It was like a little miracle! Sometimes it's the small things (not fonts!) that make a person happy.
If you can't read your screen anymore and the problem isn't your glasses, try Ctrl + on a PC, Command + on a Mac.
And if you go too far and the font becomes giant, you can make it smaller with Ctrl - (PC) or Command - (Mac).
