Framing Art can be a tricky business and expensive. I try to use standard size sheets of watercolor so that the artwork can be easily framed. Not everything is standard however. I like using Arches 10″ x 14″ pads of 140 lb cold press. There aren’t many frames out there for 10″ x 14″ openings. A solution I have found is Art to Frames Inc or arttoframe.com in Brooklyn, New York 718-788-6200.
On their website you can enter the size of the opening (next smallest integer inch) to see what your options are for frames and matting. As an example, I would enter 9″ x 13″ since it is the next smallest integer. If the paper was 10.5″ x 14.5″ then I would enter 10″ x 14″ for the opening. On the left side of the web page be sure to check Frame + Single Mat. The outer frame size will be 16.5 x 20.5 inches. This can be checked in the product information before you add to cart.
Play around with this page to see what looks best. You can even upload a photo of the image (should be same aspect ratio as the opening) to see what the frame and artwork will look like together!
