You can set/change not only the size, but the specific font you like in most browsers.
Currently I use Palatino Linotype 16 for my usual browser.

If you really LIKE to play, you can set colors of links and whether they are underlined of not...etc...

There is stuff in the tool/menus that 98% of folks never look at. (I always reduce the size of the icons on my desktop and have a program to auto-hide them after 10-15 seconds...until I move my cursor.

You 'can' control most everything about your computer's display if you choose.
