Using 96ppi is deeply misguided, confusing the two things, conversion factors and true pixel density. The 96ppi value used by Windows is simply a conversion factor used to convert from real-world lengths into pixels suitable for rendering. This has absolutely _nothing_ to do with px as a CSS unit (as used in font-size: 16px). If there really is a desire to select a value that resmbles that of the average Joe Windows, it is necessary to have the following information: 1. screen resolution 2. the physical dimensions of the monitor This will result in a value that gives the size of a rendered pixel - a true pixels-to-points value as opposed to points-to-pixels. This value in no way relates to either the 72ppi or 96ppi used by typical Mac or Windows systems. To approximate what the average user has, 85ppi is much more reasonable. ===== ---------------------------------------------------------- From Matthew Brealey (http://members.tripod.co.uk/lawnet (for law)or http://members.tripod.co.uk/lawnet/WEBFRAME.HTM (for CSS)) __________________________________________________ Do You Yahoo!?
