We went to 22x34 Ansi D to mitigate the 1/8" vs 1/4" scale issue. We use the labels for the principal scale, and add a note that translates the scale for the former. Much like civil drawings will do.
I was specing the ANSI size, but then I found out they charge a considerable amount more at the printing service places for the 22" over the 24" roll. So, I went back to ARCH D, just has a bit wider margin area. The cost was truly significant enough to do this for my builders. I print 11x17, but all the 1/4 scale printing is done just down the street at my local office max. I and all my builders use them so when plan has my name on it, whom ever is paying gets 15% off the top right away and then their "quantity discounts as well" for a certain SF of paper used.
I researched enough to help save a few bucks for my clients, and also saw their printer setup ( I owned a 12k large format unit for over 15 years) they use 3 rolls, 24" wide, 36" wide and 48" wide.
