Need to replace a door (inner) and need to know how to measure and cut the moulding, I have a mitre box.

With the door installed, set a reveal of about 1/4 inch. This is the amount that the casing sits back from the jamb. Measure from the floor up the vertical side to a point 1/4 inch above the hortizontal. This is the inside vertical measurement. This is where the inside cut will be made at 45 degrees. It will angle out from this point with the casing longer on the other side of the casing. Depending upon your architecture, the thin side if the casing goes towards the door.

Position this vertically, use a level if you have one. and attach it. Same for the other side. The horizontal piece is measured from the angles revealed at the top of the vertical pieces and cut with two 45 degree angles.

It is helpful to have the miter box attached to a board so that you can hold it with your knee. That way you don't have to try to hold the casing in the box while holding the miter box still. Or you could attach it to a workbench.

Hope this helps.
