Hip Rafter Length Calculator
This calculator determines a hip rafter's length based on the roof's total span and pitch. Hip rafters run diagonally from the corners of a building to the ridge board. This tool includes an optional eave overhang to calculate the required cut length.
To calculate a common rafter based on run and pitch, use the
Common Rafter Length Calculator.
For determining the ridge height of a hip or gable roof, try the
Roof Truss Height Calculator.
If you need the angle of the roof slope from pitch, see the
Roof Pitch to Angle Calculator.
