Nominal lumber sizes are larger than actual dressed dimensions. This chart lists the standard actual dimensions for common nominal sizes.
Common Sizes
2x4 = 1-1/2 in x 3-1/2 in; 2x6 = 1-1/2 in x 5-1/2 in; 2x8 = 1-1/2 in x 7-1/4 in; 2x10 = 1-1/2 in x 9-1/4 in; 2x12 = 1-1/2 in x 11-1/4 in; 4x4 = 3-1/2 in x 3-1/2 in.
Notes
Green (undressed or rough-sawn) lumber dimensions differ. Engineered wood products follow manufacturer-published dimensions, not this chart.
