Well, in order to implement CSS2's font-size-adjust, I would *have* to get that ratio, so I guess I would just do "the right thing", which I'm going to suggest would be the following: Measure the height of the letters that normally have the same height as 'x', i.e. acemnorsuvwxz. Check the x-height value in the font (if any). If the font's x-height value is "too" different from the median of the x-heights of the above-mentioned glyphs, then ignore it, and use the median. If the font's x-height is within a certain range from the median, use it. How's that sound? Or are you saying that font-size-adjust should be removed from the CSS spec? Erik
