Step 2: Square the Bed Frame
I will start with squaring the frame, but both leveling and squaring have to go together. You
can have the frame perfectly level, but be out of square and vice versa. Any adjustment to
one will effect the other. Depending upon how much of a perfectionist you are determines
how close to square and level you make your frame.
If the frame is square, it helps everything fit together properly, but it doesn't have to be per-
fect. This is rough framing not fine cabinetry work. The best way to square a rectangular

the same. For example, the outside diagonal measurements of an 8 ft by 10 ft frame ( Figure
46 ) should be just a hair over 156 inches long. If they are within a quarter of an inch, bump
it one time and measure again. That's probably close enough for a raised bed frame.
