Enter the base of the road and height of the camber into the calculator to determine the road camber angle.

Road Camber Formula

The following equation is used to calculate the Road Camber angle .

A = tan-1(H/B)

  • Where A is the road camber angle
  • H is the height of the camber
  • B is the base of the road

To calculate the road camber angle, take the inverse tangent of the height divided by the base.

What is a Road Camber?


A road camber is a designed slope with a peak in the center of the road to help with drainage of rain water.

How to Calculate Road Camber Angle?

Example Problem:

The following example outlines the steps and information needed to calculate the Road Camber Angle.

First, determine the height of the camber. In this example, the height is measured to be 5 inches.

Next, determine the base of the road. This is road has a base of 80 inches.

Finally, calculate the road camber angle using the formula above:

A = tan-1(H/B)

A = tan-1(5/80)

A = 3.576 degrees
