I offer poster prints on 11x14" paper. The image is 10x10" or 9x13", depending on orientation. This leaves room for matting and framing.
Or, if you want something small and ready to hang, you might like a mini-print! 6x6" or 5x7" prints mounted on wood.
My canvas prints are reproductions with gallery wrap edges and come equipped with hanging hardware making them ready to hang without framing..
