Actual Plywood Thickness Calculator
Convert nominal plywood thickness to actual dimensions
Understanding Plywood Thickness
Plywood's actual thickness is typically less than its nominal (listed) thickness. This difference is due to manufacturing processes, including:
- Sanding of the surface layers
- Wood shrinkage during drying
- Manufacturing tolerances
- Industry standards for compatibility
