Ratio1 : 12.5
Slope distance100.32
Enter the horizontal run and vertical rise to calculate the slope as a percentage grade, an angle in degrees, a "1:x" ratio, and the actual slope distance. Useful for ramps, DIY stairs, or figuring out how steep a road grade is.
How to use
- Enter the horizontal run (in meters).
- Enter the vertical rise (in meters).
- The grade percentage, angle, ratio, and slope distance are calculated automatically.
FAQ
What does slope as a percentage mean?
It's the rise expressed as a percentage of the run. For example, a road with 8m of rise over 100m of run has an 8% grade.
What does the "1:x" ratio mean?
It shows how many units of run correspond to 1 unit of rise. Accessibility ramp codes often specify a minimum like "1:12" using this notation.
What's the difference between angle (degrees) and grade (%)?
Grade is the rise-to-run ratio expressed as a percentage, while angle is the tilt from horizontal expressed in degrees. They scale differently โ a 45-degree angle corresponds to a 100% grade.
