Question: how many board feet are in a 2x4?
Answer: Re: board feet per 2x4 A 16' 2x4 will have 10.6 board feet and a 14'-2x4 will have 9.3 board feet. multiply the height in inches times the width in inches times the length in feet and divide by 12. It's easy to remember. You see most of the formula when you look at the sign in the lumber yard.
