This chart is used in our industry to calculate the footage of frame
needed for your project based on the width of the moulding.
A 24 X 36 frame seems like it would take 10' but depending on the
moulding width
it can take up to 14'. To use the United Inch Chart, add
"side 1" + "side 2"
(this will give you the "united inches" of your frame). Then go
to your
width of frame. You can see the number of feet needed to complete
your project.
