My portfolios are printed mostly on 11x14 paper (various aspect ratios). I like 16x20 on a 28x32 board really well for exhibitions and display in large enough rooms. I print detail subjects and some still lifes on 8x10 paper, but for most work, 8x10 is too small for me (one reason I've never moved to an 8x10 camera and contact prints...). I've got capacity in my new darkroom for up to 20x24 but have yet to make any that size. Soon...
