My arts prints are standard sizes in the U.S. so it should be pretty easy to find frames for them. The frame shown in the photos is an 11x14 inch frame with an 8x10 matte. I've also seen it in a 16x20 with an 11x14 matte, for the larger prints. Another option is the online framing shops like Framebridge or Simply Framed. Basically you mail them what you want framed and then they frame it and ship it back to you.
