For framing, I'd probably lean toward 18 x 22 or 20 x 24.
Thanks for the useful suggestion. I also noticed that a 12x16 mounted on 16x20 looks just about fine without a window overmat, but seems strained when overmatted and framed. So while convenient, matting 12x16 to 16x20 makes it hard to frame it later, meaning that a reprint would be necessary, hmm... Ideally, I'd settle on one print and mat size, and deciding that gets even harder when I think of square prints.
