Lumber Calculator
Calculate lumber volume, board feet, and material costs for woodworking projects.
About Lumber Calculator
ToolsOfIndia built the Lumber Calculator for carpenters, woodworkers and contractors who want straight answers in plain language. Estimate the lumber needed for a project by entering the dimensions and the number of pieces, with the tool returning the volume in cubic feet, the board feet and the linear feet. Indian carpentry orders wood in cubic feet, and the tool handles common species and sizes, with a wastage allowance for cutting. The tool also works out the cost from a per-cubic-foot rate, which is how timber is quoted. Because it is a pure local calc, nothing is uploaded. It is the lumber estimate that a furniture or shuttering order always needs. Estimates are framed the way Indian contractors and material suppliers actually quote, so you can compare numbers directly with the local rate card. Real-world uses include estimating wood for furniture, ordering shuttering plywood for a slab, and costing a carpentry job from a rate. Results update as you type, so you can play what-if games instead of redoing the whole calculation.
