One board foot is equal to a 12-inch length of 1 x 12

```Nominal Value of Lumber:
A length of  2 x 4 has an actual size of 1 1/2" x 3 1/2". The nominal value is 2" x 4".
A length of 2 x 10 has an actual size of 1 1/2" x 9 1/8". The nominal value is 2" x 10".
A length of 1 x 4 has an actual size of  3/4" x 3 1/2". The nominal value is 1" x 4
