Enter the height and the width at half-height into the Calculator. The calculator will evaluate the Peak Area. 

Peak Area Formula

PA = h * w1/2


  • PA is the Peak Area ()
  • h is the height
  • w1/2 is the width at half-height

To calculate the Peak Area, multiply the height by the width at half-height.

How to Calculate Peak Area?

The following steps outline how to calculate the Peak Area.

  1. First, determine the height. 
  2. Next, determine the width at half-height. 
  3. Next, gather the formula from above = PA = h * w1/2.
  4. Finally, calculate the Peak Area.
  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.

height = 50

width at half-height = 10
