Enter the total compression (in) and length (in) into the Calculator. The calculator will evaluate the Compression Rate Per Inch. 

Compression Rate Per Inch Formula



  • CRPI is the Compression Rate Per Inch (In/in)
  • TC is the total compression (in)
  • L is the total length (in)

To calculate the Compression Rate Per Inch, divide the total compression by the total length.

How to Calculate Compression Rate Per Inch?

The following steps outline how to calculate the Compression Rate Per Inch.

  1. First, determine the total compression (in). 
  2. Next, determine the total length (in). 
  3. Next, gather the formula from above = CRPI = TC / L.
  4. Finally, calculate the Compression Rate Per Inch.
  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.

total compression (in) = 30

total length (in) = 50
