How it works
Determine roof pitch and slope angle from rise and run.
Who it's for: Roofers, architects, and homeowners comparing roof styles or ordering materials.
Pitch is expressed as X:12 — inches of rise per 12 inches of horizontal run.
Also calculates the angle in degrees.
Uses inches for both rise and run inputs.
How to use
- Enter Rise — vertical climb of the roof slope in inches.
- Enter Run — horizontal span per 12 inches of run (typically 12 for standard pitch notation).
- Read Pitch as X:12 and Angle in degrees.
