The margins are not too huge. That statement makes no sense at all.

There are about 75 character per line, that’s pretty much the sweet spot for characters per line. Going for a few more characters would be ok (120 is a usual guideline for the maximum), but 75 is pretty good. It’s actually pretty much the standard. I learned 60 to 90 characters per line.

Margins are your problem. Your browser is too wide. (I agree that the font is much too small. Also, Verdana is seriously ugly. A better font at a larger size would reduce the size of your margins, even if you are one of those strange fullscreen browser people.)
