How To Measure A Picture Frame For Cutting. All of our frames are measured by the inside dimensions. The “frame” pieces will be about 3 inches wide and the same thickness as the rest of the project.
It is a common mistake to think the dimensions are the width and height of its outside edges. Then measure the width (facing you) of the frame material you’ve chosen. I’m going to have to figure out how to do this at some point or another.
Measure the picture you want to frame.
Make sure that you leave a tiny bit of extra room to accommodate glass and/or matte. Measure the amount of inset for the picture on the back of the frame (probably around 1/4″). Add 6 for a 3 wide moulding so the 16 x 20 becomes 22 x 26. I’m going to have to figure out how to do this at some point or another.
