I recently got a 30″x20″ print done at Photobox while they had a special offer, but now that I’ve come to buy a clip frame for it, I can’t seem to find a 30″x20″ frame. All frames seem to be metric. There is one size close (750 x 500mm), but it would mean trimming an unacceptable amount off the photo and losing part of the border on the print. (30″x20″ is 762 x 508mm)
30″x20″ is a standard photo size, so why does no-one make a frame to suit?
