Framing an artwork is a very personal thing, thus what I’m about to suggest is just my view. I believe that the frame and mat used to frame a print must match the feel and color that is in the image, but there are many a combination of frame and mat that can match the image as well as your own personal style and decor in your house. My major rule is to find in the image the over all subtle color and select a mat that will match that color. This highlights that color more and gives your image a more three dimensional feel. I use this same technique with the type of color in the frame used as well, but you also need to think about the profile (shape) of the frame and make sure it works with the feel of the image and your decor. I always recommend using normal glass as much as you can, rather then standard non reflective as it softens and reduces the color clarity by around 10%. Never use standard non reflective glass in an artwork that’s right next to a wind or at 90 degree angle to the window, as the glass appears quite opaque.
The image below will give you an idea of matching frame and mat to image, also you’ll notice I’ve put in mat width and frame width, this is based off a 860mm x 275mm size print. But you could use the same ratio of frame to mat to print for other size prints. Naturally this is a very personnel thing and really just depends on what you like.
All of my canvas images are designed for the image to be stretched around the frame, the image wraps around onto the back of the frame by 5mm. The frame depth that my canvases are designed to suit is around the 28mm in depth. Once the canvas has been stretched it’s a great idea to get the framer to put a protective coating over the canvas as this will lengthen the life of your artwork. Your framer will have his preferred protective coating that he uses.
