A2 = 594 x 420 mm A3 = 420 x 297 mm A4 = 297 x 210 mm A5 = 210 x 148 mm, etc. Those sizes existed for a long time, but for photography they were relatively unimportant before digital-probably because of Kodak, photo lab used metric approximations of the American sizes - 4 x 6 inches = 10 x 15 cm, etc.4 is standard document size 8 1/4 inch by 11 3/4 inch. A3, off the top of my head is near enougth 12x16 inch. In the UK standard print sizes are 10x8, 12x16 and 20x16. A4 has rapidly become a standard size as a result of inkjets I think. Sizes like 11x14 are hard to come by in the UK.
