Slope geometry
Distance Along Slope Calculator
Find the actual sloped distance between two points from horizontal run and vertical difference. Grade and angle are shown as supporting measurements.
Slope inputs
Enter horizontal and vertical dimensions.
Why slope distance is different
Horizontal run is the plan projection. The physical distance along the slope is the hypotenuse of the right triangle formed by the run and vertical change.
Sloped distance = √(horizontal² + vertical²)
Example
For 12 m horizontal distance and 1.5 m rise, the true sloped distance is approximately 12.093 m.
Common use
The result can support sloped surface measurement, ramp geometry, site access measurements and other two-dimensional slope calculations.
Frequently Asked Questions
Is slope distance longer than horizontal distance?
Yes, except when vertical difference is zero.
How is slope distance calculated?
Use the Pythagorean relationship between horizontal and vertical components.
Can this calculate a three-dimensional route?
No. It is a two-dimensional slope model.
