The algorithm [1] for converting a character width to pixels is good indeed, except that it should be formulated in terms of glyphs and not characters because stand-alone characters are not displayed or perceived as such for some scripts. If the primary font for which the algorithm is being run comprises several scripts, as it typically does, characters of the script of the effective language of the control should take overwhelming weight in the average. This algorithm does not fulfill the requirements for the size attribute formulated in section 4.10.4.2.4 [2]: when it is applied, it may happen that the user agent will not be able to allow the user to see the whole text it should be able to allow. The requirement should be modified to match the effect of the algorithm.
