Angle of Repose Calculator: Determine Material Slope Stability

Calculate Your Material's Angle of Repose

meters
Enter the vertical height of the material pile (same unit as radius).
meters
Enter the radius of the circular base of the material pile (same unit as height).

The Angle of Repose Calculator helps you determine the maximum stable slope for various granular materials. Input the pile's height and base radius to instantly find the angle, crucial for designing bunkers, conveyor belts, and preventing landslides. Understand material stability for construction, agriculture, and bulk storage.

Formula:

The Angle of Repose (θ) is calculated using the following trigonometric formula:

θ = arctan(Height / Radius)

  • Height: The vertical height of the conical pile of material.
  • Radius: The radius of the circular base of the conical pile.
  • arctan: The inverse tangent function, which gives the angle whose tangent is Height/Radius.
