Elevation Grade Calculator
Calculate the slope percentage, angle, and ratio for construction, roads, ramps, and hiking trails. Determine elevation grade based on rise and run measurements.
Step 1: Elevation Parameters
10 ft
100 ft
Understanding Rise and Run
The “rise” is the vertical change in elevation, while the “run” is the horizontal distance. Grade is calculated as (rise ÷ run) × 100%.
Step 2: Calculation Options
Common Grade References
A 5% grade is typical for roads, 8.3% for wheelchair ramps (1:12 ratio), and 15-20% for steep hiking trails. Grades over 30% are considered very steep.

Grade Calculation Formula
Grade Percentage = (Rise ÷ Run) × 100%
To calculate the angle: Angle = arctan(Rise ÷ Run). The slope ratio is expressed as 1:X where X = Run ÷ Rise.
