Calculate cut length, pieces per stock, stock lengths needed, kerf loss, leftover scrap, and material yield in millimeters, centimeters, meters, inches, or feet.

Required: stock length, pieces per stock, and kerf.

Kerf is the width removed by the blade for each piece cut.

Cut Length Formula

The following two example problems outline the steps and information needed to calculate the Cut Length.

CL = L / P
  • Where CL is the Cut Length
  • L is the total length of material 
  • P is the total number of pieces needed 

To calculate the cut length, divide the total length of material by the number of pieces needed.

How to Calculate Cut Length?

The following example problems outline how to calculate Cut Length.

Example Problem #1:

  1. First, determine the total length of material.
    • The total length of material is given as: 400.
  2. Next, determine the total number of pieces needed.
    • The total number of pieces needed is provided as: 10.
  3. Finally, calculate the Cut Length using the equation above: 

CL = L / #P

The values provided above are inserted into the equation below and computed.

CL = 400 / 10 = 40.00

Example Problem #2: 

For this problem, the variables required are provided below:

total length of material = 300

total number of pieces needed = 20

Test your knowledge using the equation and check your answer with the calculator..

CL = L / #P = ?
