How to calculate the length of moulding you need.
Example: You need to make a frame to fit a 12x16 inch board. (305x407mm)
The moulding width is 66mm
Calculate the perimeter of the board ie the frame size.
305+305+407+407mm = 1424mm
add a little fitting tolerance = 1428mm
Calculate wastage ie 8 45 degree cuts.
66mm x 8 = 528mm
Total length of moulding required
1428mm + 528mm = 1956mm
Purchase 2 x1.5m lengths
You will have some left over for another frame
66mm Flat - 1.5m Lengths
Rebate Depth: 13mm
Takes a painted finish well. Can also be waxed.
