`P = "rise" / "Run"
`

Enter a value for all fields

The **Roof Pitch** calculator computes the pitch of a roof based on the rise (r) and the run (R).

**INSTRUCTIONS:** Choose units and enter the following:

**(r) rise:**This is the measure from the base of the gable to the apex of the roof (see diagram).**(R) run:**This is the measure from edge of the roof to the mid-point or highest point of the roof (see diagram)

**Pitch(P):** The calculator computes the angle of the pitch in degrees and the approximate rise over run (e.g. 4/12)
