Roof Pitch Calculator

Roof Pitch Calculator

Calculate roof pitch from the rise and run.

* Rise in inches; Run in inches.

Step 1: Enter Roof Data

Enter the vertical rise in inches.

Enter the horizontal run in inches.

Calculations:
Pitch Ratio = Rise : Run
Slope % = (Rise ÷ Run) × 100%
Roof Angle = arctan(Rise ÷ Run) × (180/π)
