# Rafter Length Calculator

Calculate the length of a rafter from roof pitch and a length measurement. Includes result for hip/valley factor, slope factor and the roof angle in degrees

If you add an overhang dimension then that would be the amount the rafter sticks passed the wall in the calculation.

Example if you have a 2' overhang and a 1 1/2" fascia board you would enter 22 1/2" (22.5" in the calculator) in the overhang field of
the calculator to get the rafter length.

### If using a ridge board subtract half its width from the rafter length

#### Calculation

- length in feet and inches
- pitch of the roof
- length of overhang in inches

#### Results

- the angle of the roof in degrees
- slope factor (for common rafter)
- hip/valley factor
- length of rafter in decimal feet
- length of rafter in feet and inches
