What else matters here
A 4x4x8 is 10.67 board feet, exactly the same as a 2x4x16. A post is counted the same way as any other piece: nominal thickness times nominal width times length in feet, divided by 12.
What this calculator assumes
- A board foot is nominal thickness times nominal width times length in feet, divided by 12. Use the nominal size, the 2 and the 6 in a 2x6, not the real 1.5 by 5.5.
- Hardwood is sold by the board foot. Softwood framing is usually sold by the piece, so this is for pricing and for comparing two quotes written differently.

What is a board foot?
