Calculation Formula

Slope Length = √(Rise² + Run²)

Where:
Rise = vertical height
Run = horizontal distance
Slope Length = length of the slope

Length of Slope Calculator Calculator Usage Guide

Learn how to use the Length of Slope Calculator calculator and its working principles

How to Use This Calculator

  1. Enter two of the following parameters: Rise, Run, or Slope Angle
  2. The calculator will automatically calculate the third parameter and display the results
  3. You can calculate the slope length when you know the rise and run
  4. You can calculate the rise when you know the slope length and run
  5. You can calculate the run when you know the slope length and rise

Formula Used

The calculator uses the following formula to calculate the slope length:

Slope Length = √(Rise² + Run²)

This is based on the Pythagorean theorem, where the slope length is the hypotenuse of a right triangle formed by the rise and run.

Applications

This calculator is useful in various fields including:

  • Construction and architecture for staircases and ramps
  • Landscaping and gardening for sloped terrain
  • Surveying and mapping
  • Roofing for calculating roof pitch
