I'm not in favour of this unless its worded as "implementations must also accept...", because a drop-down list with all the ISO sizes prefixed by ISO would be quite irritating, especially for US and Canada people who'd have to scroll past them all to get to US Letter, US Legal and US Tabloid. :-) > There are many more paper formats we could consider, and for instance > Antenna House supports the following > http://www.antennahouse.com/product/ahf60/docs/ahf-ext.html#axf.size > > I would support extending the list in the specification in that > direction, but resolving the ambiguity and confusion with regards to > the B series seems higher priority. Envelope sizes are worth including (in North America especially "envelope #10"), but once you get beyond the sizes that come in printer description files it's generally easier for people to specify sizes in inches/mm/feet/metres (e.g. for a large poster printed on a 4'-wide inkjet). There are whole series like SRA (e.g. SRA4, SRA3) and ANSI variants such as A3+ / Super B / B+) for printing with bleed and/or crop marks and colour lines. A shorter list is more helpful in a UI, and the AH one seems a little arbitrary, but I strongly agree with you about the confusing sizes.
