Is it possible to think of a measure, which is proportional to the angular size of a feature at hand? according to: "as viewed at normal conditions for a particular display"? I mean: a measure that will represent the same amount od "steradians" irrespectively of the fact, that the "thing" (like a font) is displayed on 5" FullHD (1900x1080) galaxy note, and an old 14" notebook screen of 800x600 pixels, or for that matter: 60" UltraHD TV, taking into account, that those displays are normally used at different distances from eyes, like: 24cm, 70cm, 2m respectively. I'm looooning for something like pica-point-steradian (ps), defined so, that "font-size: 10ps" would render as 10pt font on kindle (and would print as 10pt font on paper), and when rendered on my notebook would "apear" to me as 10pt font on paper held "at bended arms length" .... so would render on such screen to 12pt or similar. No more dpi, px, pt, cm, in,... those should be hidden by display/browser internals. -R
