Equal Cuts Calculator

Calculate the optimal length for equal pieces when cutting material, accounting for saw blade kerf to minimize waste.
How to Use
  1. Choose your preferred unit (millimeters or inches)
  2. Enter the total length of your material
  3. Enter your saw blade's kerf width
  4. Select your desired granularity (for inches) - this determines the smallest unit of measurement
  5. Select your desired number of pieces from the results table
  6. Set up your stop block at the calculated piece length
  7. Make your cuts - the remaining material should be just enough for the final piece
Example

Let's say you have a 96-inch board and want to cut it into 4 equal pieces using a saw with a 1/8-inch kerf:

  1. Select "Inches" as your unit
  2. Enter "96" for the total length
  3. Enter "0.125" or "1/8" for the kerf width
  4. Select "1/8 inch" for granularity (this means measurements will be rounded to the nearest 1/8 inch)
  5. The calculator will show you that each piece should be 23 7/8 inches
  6. Set your stop block to 23 7/8 inches
  7. After making 3 cuts, you'll have 4 equal pieces with minimal waste

Note: Choosing a smaller granularity (like 1/64 inch) will give you more precise measurements but may result in more complex fractions. A larger granularity (like 1/2 inch) will give you simpler measurements but might result in slightly more waste.
