Rise Over Run Calculator

Find slope as rise divided by run, plus the angle.

Calculated Output

Slope 0.5

Angle (°) 26.565

Formula: slope = rise ÷ run

Step-by-Step Breakdown

1. Values used:

2. Rise = 4

3. Run = 8

5. Slope = Rise / Run = 4 / 8 = 0.5

6. Angle = 26.565°

Did this calculator solve your problem today?

The math behind it

slope = rise ÷ run. The angle of inclination is arctan(rise ÷ run).

Rise 4 over run 8 → slope 0.5 (about 26.57°).

What if run is zero?

The line is vertical and the slope is undefined.
