What is the minimum thickness OSB usually comes in?

Oriented Strand Board (OSB) is commonly used in construction for sheathing, flooring, and other applications due to its strength and versatility. The minimum thickness that OSB typically comes in is 3/8 inch. This thickness is suitable for various structural applications and ensures sufficient strength for supporting loads and resisting warping or bending.

OSB panels are produced in standard sizes and thicknesses, and 3/8 inch is recognized as a foundational thickness for many construction projects, particularly where moderate load-bearing and structural integrity are required. Thicker options are available for more demanding applications, but 3/8 inch serves as the baseline for standard-use scenarios in framing and sheathing. Understanding this helps contractors and builders select the appropriate material based on the structural requirements of their projects.
