The span of a building is 16 feet and there is an overang of 1 foot. If the length of the hip rafter per foot of common rafter run is 17.69, what is the length of the hip rafter? Make 1 1/16 inch ridge allowance.

If the length of the common rafter run is 12 feet, and the length of hip rafter per foot of common rafter run is 18 inches, how long is the hip rafter? Make allowance for the ridge using a 2 inch ridge board.

__________ run from the corner of the building to the ridge at a 45 degree angle.

On the framing square, the second number below the 5 inch mark is 17.69. This means that the length of the __________ is 17.69 inches per each foot of the __________ run.

What is the common rafter run if the length of the hip rafter is 178 15/16 inches and the rise per foot of run is 6 inches?

If the hip rafter includes an overhang, add an overhang of the common rafters to the run of the common rafters.

The length of hip rafters can be found by using a table found on most framing squares.

The __________ line of the table on the framing square is used to calculate the length of hip rafters.
