OSB Calculator
Calculate the exact number of OSB sheets needed for your construction project. Determine material requirements, costs, and wastage for walls, roofs, and floors.
Step 1: Project Dimensions
About OSB Sizing
Standard OSB sheets are 4×8 feet. Use 1/2″ for walls, 5/8″ for roofing, and 3/4″ for flooring. Always add 10% extra for cutting waste.
Step 2: Cost & Wastage
Cost Considerations
Consider adding 10-15% extra material for wastage. Factor in fasteners, delivery costs, and potential price fluctuations.
