I kept changing my posts font and checking it to the blog to see whether it's size is comfortable for reading. Some fonts are so thin, unless you set the font to large, it is almost impossible to read on the PC screen!(I have a bias towards big letters)
I've always preferred font sizes that aren't so thin or bigger font sizes that are actually suitable for the human eye.
Even when I pick a book from the library, I would always check whether the words are big enough to read. And it's not because I'm myopic, it's just because it's easier to read!
I do have friends who prefer small fonts.
It's just a preference. :O
(I don't know but sometimes I feel that those tiny little words will come out of their pages, scramble onto my hands and jump on my face to eat me alive.)
