Calculate driveway slope (percent and degrees) from rise and run — also called a driveway pitch calculator.
Driveway slope / pitch calculator
Slope % = (rise ÷ run) × 100 when rise and run use the same units. This tool converts rise in inches and run in feet. Many residential drives use a gentle pitch for drainage — local codes and your paver decide what is safe for ice and cars.
