Roof Pitch Calculator
Calculate pitch, slope, and angle from rise and run for estimating materials and confirming design specs. Use it to get accurate slope before estimating squares, bundles, or panels.
Inputs
Tip: At this pitch, total rise over a 24 ft span is about 72 inches (half-span).
Results
Pitch
6 / 12
Slope: 50% • Angle: 26.57°
Assumptions
- Rise and run are measured on the same roof plane.
- Pitch is normalized to 12 inches of run.
- Ignores overhangs and complex roof geometry.
Next Steps
- ✓ Convert area with the roofing squares calculator
- ✓ Review the roofing calculators guide for ordering tips
Example
A 6 in rise over 12 in run equals a 6 / 12 pitch with a 50% slope.
