We need the width and height of your artwork to the nearest 1/8”. Flatten out your print as much as possible and measure from paper edge to paper edge for each measurement. Round up to the higher 1/8” if you are in between. If centimeter measurements are more accurate, go with the closest dimensions in inches and then include the cm measurements in the 'Special Instructions' field at checkout -- we'll produce the frame according to the measurements in cm.
Note that the mat if you have selected one, will overlap your artwork by approximately 1/4” on each side so as to secure it inside the frame. Unmatted frames will overlap the print by 1/8" on each side.
If you would like the mat to overlap your print by more or less than the standard 1/4”, or have any other special requests on the size of the mat window opening, please contact us via chat or firstname.lastname@example.org.
