Hardwood is priced by the board foot. Enter a stack of lumber and see the volume and the bill.

How it works

Thickness in inches × width in inches × length in feet ÷ 12 gives board feet per piece. Multiply by the number of boards.

Before you order

  • Rough hardwood is sold by its thickness in quarters, so 8/4 means 2 inches.
  • Mills add to the bill for surfacing, so compare rough and planed prices.
  • Buy about 20% more than the cut list when you need matched grain.

Common questions

What is a board foot?

A piece 12 inches wide, 12 inches long and 1 inch thick, or 144 cubic inches.

Do I use actual or nominal size?

Yards charge on nominal size, so a 2×6 counts as 2 by 6 even though it measures less.
