How Many Linear Feet In 100 Board Feet Of 2x6
145.5 linear feet
- 2x6 (actual 1.5" x 5.5")
- 0.688 board feet per linear foot
Methodlinear feet = 100 / (board feet per linear foot of this cross-section).
This conversion only works for a SINGLE fixed cross-section — mixing sizes means totaling board feet, not linear feet, first.
100 board feet of 2x6 works out to about 145.5 linear feet — a single 2x6 (actual 1.5" x 5.5") produces 0.6875 board feet per running foot, so it takes considerably more than 100 running feet to reach 100 board feet at this cross-section.
Why this one specifically
This conversion matters at the estimating stage, when a supplier quotes 2x6 by the linear foot but a project's material list is figured in board feet, or the reverse — going from a board-foot total back to how much actual length to order or how many sticks a given run requires. It only works for a single, fixed cross-section: mixing 2x6 and 2x4 in the same project means totalling board feet across both sizes first, then converting each size's linear-foot need separately, not converting a combined board-foot total back to one linear-foot number.
What moves the number
Cross-section is the whole story — a thinner or narrower profile than 2x6 needs more linear feet to reach the same 100 board feet, while a thicker or wider one needs less. Length of the individual boards purchased doesn't affect the total linear footage needed, only how many separate pieces that footage comes in.
