Think of the volume of a piece of wood that is 12" x 12" x 1" or 144 square inches. A board-foot equals that same volume regardless of its surface area. So, a board-foot of a piece of wood that is over 1" thick will have a smaller surface area and you will need more board-feet than you would square feet to cover the same area. If the wood is less than 1" thick it is counted as 1" regardless. It is a little confusing which is why most flooring is sold by the square feet of the surface area and not by volume or board-feet.
