Hello Felix, Very interesting discussion in which I am learning much. What you say above got me thinking and I have decided to do a test case. <http://css-class.com/test/css/box/pixels-points-dpi.htm> This is what I note: 1. The 96px and 72pt boxes are the same size with a 96 DPI setting for the monitor. 2. The 100px and 75pt boxes are the same size with a 96 DPI setting on a monitor but also they are exactly 1 inch (using a ruler) in height and width. 3. When the DPI setting is changed to 120 DPI, the boxes using pts become 125% of their size at 96 DPI. 4. The boxes using pixels are the same size and the box of 100px at either 96 or 120 DPI still equals exactly 1 inch (using a ruler) in height and width. On the same test case are screenshots using both 96 DPI and 120 DPI. My question to you is why a box of 100px equals a inch measured by a ruler and not what I expected 96px? BTW, I thought the higher DPI setting would make the text smaller. I now discover the reverse is true where the text and chrome of the browser is larger. -- Alan http://css-class.com/ Armies Cannot Stop An Idea Whose Time Has Come. - Victor Hugo ______________________________________________________________________ css-discuss [cs...@lists.css-discuss.org] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
