Wood Sizing - Nominal vs. Actual Lumber Sizes: In North America, wood sizes are given in "nominal" measurements, which is the lumber’s size when it is cut from moist logs. After shrinkage from drying and surfacing, the actual size of lumber will be less than its nominal size. Please see the diagram for actual dimensions.
