When I was debating style wars in the 90's, we adopted a 'wide is OK'
approach, but with a soft limit of ~130 and a hard limit of 160 in
exceptional cases. There was some research that showed that there's a
limited field of view you want to be able to look at the code without
moving your eyes side to side, just up and down. With the technology of the
time, above about 130 would be hard to read 'at a glance'. Years later, I
went looking for those studies, and couldn't find them and the original
advocate of the view couldn't provide them.
I'm the first to admit that 80 is too few. But 200 is definitely too wide
and 100-120 seems to still be the sweet spot for my eyes and the range of
hardware that I use.
