Wood is a natural material, and its dimensions are often described using a system of nominal versus actual measurements that can be confusing. 25" Rim joists, heavy load beams.
Actual Wood Sizes Industry Consistent Material Estimates
If you are building a frame and need a specific gap or joint dimension, calculating based on the nominal size will result in a structure that is too small. 5 inches by 3.
Below is a table outlining the most common sizes for standard framing lumber. When a tree is first cut, the lumber is green, meaning it has a high moisture content.
