This is an informal discussion forum. Merely because I don't produce citations every time I mention a fact doesn't imply that I'm not basing my assertions on fact. Here is one such study <URL:http://www.psychology.nottingham.ac.uk/staff/mxh/Papers/Dyson%20&%20Haselgrove%20%282001%29.pdf>. But there is plenty of room for uninformed diverity of opinion <URL:http://skeptics.stackexchange.com/questions/5625/are-shorter-lines-easier-to-read>. The point is less about hard evidence about *precise* limits; I make no claim about the superiority of 80 columns or 93 columns or 55 columns or whatever. Rather, the point is rather that human cognition *does* have limits, and those limits are at the basis of limits we choose to impose on text layout. Those who claim “terminals just magically happened to be 80 columns wide and we were slaves to that limit” have it completely backward: the limits were imposed *onto* the terminals by human makers, based on their understanding of the cognitive limits of the humans reading from them. Those limits are with us still, and to my knowledge have not improved with recent human generations. > Also, not everything that applies to prose also equally applies to > code. If you're going to counter evidence of general human reading cognition by making special claims about code, that would need to be backed up with specific evidence. > Personally I find overly narrow code (80 cols) to be much *harder* to > read than code that is 100 cols wide. I counter your anecdote with my own: I find 80 columns to be quite long, and prefer code to be no more than around 60 columns. So what do we learn? That attempts to generalise from personal anecdote doesn't get us anywhere useful. -- \ “I took a course in speed waiting.
