Turn a total length of board into pieces of stock you can pick off the rack.

How it works

Total feet plus your cut allowance ÷ stock length, rounded up. Board feet come from the size you enter.

Before you order

  • Plan cut lists so offcuts get reused elsewhere in the job.
  • Longer stock costs more per foot, so price it both ways.
  • Stack lumber flat and stickered if it will sit before you use it.
