Enter the spray distance (in) and the spray coverage (in) into the Spray Angle Calculator. The calculator will evaluate the Spray Angle. 

Spray Angle Formula

The following two example problems outline the steps and information needed to calculate the Spray Angle.



  • SA is the Spray Angle (degrees)
  • D is the spray distance (in) 
  • C is the spray coverage (in) 

To calculate the spray angle, take the inverse tangent of the spray coverage divided by the spray distance.

How to Calculate Spray Angle?

The following steps outline how to calculate the Spray Angle.

  1. First, determine the spray distance (in). 
  2. Next, determine the spray coverage (in). 
  3. Next, gather the formula from above = SA = ATAN(C/D).
  4. Finally, calculate the Spray Angle.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

spray distance (in) = 10

spray coverage (in) = 13

SA = ATAN(C/D) = ?
