If you want 96 px/in, and CSS pixels are an integer number of device pixels, then you have to pick 3:1 for that ratio, which results in a CSS inch being 288 (3*96) device pixels, which is about 4% short of a true inch.

I think in print media in particular, people expect inches to be inches, not 4% wrong. OK. That makes sense, and is not far from what I thought the reasoning might be. I was thinking of tiny inaccuracies being multiplied into bigger differences over large distances, but it is a similar problem. Physical measurements in print should be accurate.Received on Tuesday, 29 June 2010 17:56:25 UTC
