FAQ
What is a board foot?
A volume unit of 12 × 12 × 1 inches — calculated as thickness × width × length (in feet) divided by 12.
Why use board feet instead of per-board pricing?
Hardwood is sold by board feet so thick, wide, long stock prices consistently regardless of how it is cut.
Do nominal dimensions matter?
Yes — a '2×4' actually measures 1.5 × 3.5 inches; enter the real dressed sizes for accurate totals.
