2x4 (Lumber)
A 2x4 is a common size of lumber used in construction and woodworking. It measures approximately 1.5 inches by 3.5 inches in actual dimensions, despite its name suggesting otherwise. This size is often used for framing walls, floors, and roofs due to its strength and versatility.
Typically made from softwoods like pine or fir, 2x4s are available in various grades, which indicate their quality and appearance. They can be treated for outdoor use or left untreated for indoor projects. Their affordability and ease of handling make them a popular choice for both professionals and DIY enthusiasts.
