Understanding 4/4, 8/4, 12/4 Lumber

Lumber thickness is commonly measured in quarters of an inch, with 4/4 lumber, 8/4 lumber, and 12/4 lumber being popular choices for woodworking projects. 4/4 lumber (pronounced "four-quarter") starts at 1 inch thick before surfacing, making it ideal for furniture and cabinetry. 8/4 lumber is 2 inches thick, perfect for table legs and structural components, while 12/4 lumber at 3 inches is great for heavy-duty projects like carving and turning.
