Measure each side of your artwork from edge to opposite edge. The "width" is left-to-right, and "height" is top-to-bottom. Make sure to use the correct "width" and "height" so we build your frame in the correct orientation!
The yellow area is the 1/4" which will end up covered by the frame or matboard. If you have important details (such as a signature) on the very edge of your artwork, please reach out to us with a photo of it so we can help!
