Re: [NTO] Screen Resolutions
Just as a hint of what I have found to be reasonable values: I limit
all single column designs to a max-width of 42em by default and set
lengthy texts to a max-width of 34em or up to 38em, if there are
many lists, blockquotes or other items shortening the lines.
Your preferences may vary, but I think these values are about the
right ballpark. (An em is much wider than the average letter in a
line.) Also note that the correct unit in these cases has nothing to
do with pixels and thus little to do with screen resolutions. These
may do well for graphics, but line length for text should respect
the reader's choice of an agreeable fontsize.
