Enter the boom height (ft) and the boom horizontal length (ft) into the Boom Angle Calculator. The calculator will evaluate the Boom Angle. 

Boom Angle Formula

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

BA = ATAN ( BH/BL)

Variables:

  • BA is the Boom Angle (degrees)
  • BH is the boom height (ft) 
  • BL is the boom length (ft) 

How to Calculate Boom Angle?

The following steps outline how to calculate the Boom Angle.


  1. First, determine the boom height (ft). 
  2. Next, determine the boom length (ft). 
  3. Next, gather the formula from above = BA = ATAN ( BH/BL).
  4. Finally, calculate the Boom 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.

boom height (ft) = 50

boom length (ft) = 40

BA = ATAN ( BH/BL) = ?
