- 01Lumber buyingBoard foot calculator
Calculate board feet and estimated lumber cost from thickness, width, length, quantity, and price.
↗ - 02Project estimatingLumber volume and cost calculator
Estimate raw and waste-adjusted lumber volume, board feet, and material cost for rectangular stock.
↗ - 03Linear stock planningCut list optimizer
Pack repeated cut lengths into stock boards with kerf and end-trim allowances, then print a practical cutting plan.
↗ - 04Panel layoutSheet goods cutting planner
Arrange rectangular parts on standard sheets with kerf allowance, optional rotation, utilization, and cut-sheet diagrams.
↗ - 05Bench referenceFraction, decimal, and metric converter
Convert workshop dimensions among fractional inches, decimal inches, feet, millimetres, centimetres, and metres.

GUIDES & RESOURCES
Methods behind the numbers
Field-oriented references for measuring, choosing assumptions, and checking an estimate before material is ordered.
Use the 144-cubic-inch definition, tally every board, then keep defects and milling loss separate from the purchased volume.
02CUT PLANNINGCut Lists and Saw KerfA reliable cut plan reserves material for every blade path and trim cut, then tests the layout against grain, defects, and safe handling.
03SHEET GOODSSheet Nesting: Kerf, Grain, and TrimNest from a measured usable sheet, lock directional parts before allowing rotation, and treat the printout as a reviewable layout—not a saw sequence.
04CABINET FITCabinet Door and Drawer Front RevealsWork from a measured opening, put each reveal and center gap on its own line, and confirm the fit with test pieces before machining finished fronts.
