Inside Picture Framing #5: Spacing around frame components

All parts of the frame package (backing board, mounting board, mats, art, glazing) need to be spaced away from the edge of the frame so that natural expansion/contraction of each part does not cause bowing or cracking. In general, there should be 1/16” space on each side and 1/8” space at the top, more for large frames.
