Lumber sizes are smaller than their marked sizes due to drying, which causes shrinkage, and planing and surfacing, which further reduce the dimensions. The nominal sizing system was established for standardization in the lumber industry. https://diyhomewizard.com/the-mystery-of-shrinking-2x4s-understanding-the-evolution-of-lumber-sizes/
