Calculation Formula

Slope = Wall Height / Setback Distance

Angle = arctan(Slope) × 180/π

Where:
Slope: The ratio of vertical rise to horizontal run
Angle: The angle of repose in degrees
H: Height of the wall
V: Horizontal setback distance

Retaining Wall Slope Calculator Usage Guide

Learn how to use the Retaining Wall Slope Calculator and understand its importance in retaining wall construction

How to Use This Calculator

  1. Enter the height of your retaining wall in feet.
  2. Enter the horizontal setback distance in feet (the distance from the wall base to the edge of the retaining wall).
  3. Click the "Calculate" button to determine the slope and angle.
  4. The calculator will display the slope in the format "H:V" (e.g., "3:1") and the angle in degrees.

Understanding Retaining Wall Slopes

A proper slope is crucial for the stability of a retaining wall. The slope determines how water will drain away from the wall, preventing water buildup that could undermine the structure.

Common Slopes for Retaining Walls

  • For walls up to 2 feet high: A slope of 2:1 (horizontal:vertical) is typically recommended.
  • For walls between 2 and 4 feet high: A slope of 3:1 is generally advised.
  • For walls taller than 4 feet: Engineering assessment and potentially a steeper slope may be necessary.

Note: This calculator provides general guidance. Always consult with a qualified engineer or architect for specific retaining wall projects, especially for taller walls or in areas with challenging soil conditions.
