How wide is your screen (in px)? Because the max width of my layout is around the old 760px standard. You should be able to see everything (even if, as you say, it's a bit too large).

On the other hand, it's a pretty valid critique. To be honest I forgot that there are 11 inch screens (or, screens that are larger than phones but smaller than 17inch desktop monitors). I'm not on any sort of a big screen.

And indeed, my lineheight is 1.618em (golden number in math, heh). I say 1.5 because it's a nice compromise. Perhaps 1.3 or so is better in certain circumstances.
