Common Questions and Facts on
Dimensional lumber refers to lumber that is cut and sold in standardized sizes, such as 2x4s, 2x6s, etc. It's commonly used in construction and woodworking projects for framing, building, and other structural applications. The dimensions are usually nominal, meaning the actual size is slightly smaller due to planing and smoothing.
The sizes refer to the thickness:
4/4 (four-quarter) is approximately 1 inch (2.54 cm) thick
8/4 (eight-quarter) is approximately 2 inches (5.08 cm) thick
The "quarter" system is a traditional way to measure lumber thickness, where 1/4 represents 1/4 inch of thickness.
