🪵 Woodworking Calculators
Lumber, board feet, plywood, miter angles, wood movement, and deck spacing calculators.
Board Feet Calculator
Calculate lumber board feet for hardwood, rough sawn boards, dimension lumber, and woodworking projects.
Formula: (Thickness × Width × Length × Quantity) / 144
Lumber Price Calculator
Estimate hardwood and softwood lumber cost using board feet, price per board foot, and waste factor.
Formula: Board Feet × Waste Factor × Price per Board Foot
Miter Angle Calculator
Calculate miter angles for flat polygons, trim, baseboards, picture frames, and multi-sided woodworking joints.
Formula: 360 ÷ Sides ÷ 2
Wood Movement Calculator
Estimate seasonal wood expansion and shrinkage across board width using moisture change and movement coefficient.
Formula: Width × Coefficient × Moisture Change
Plywood Sheet Calculator
Estimate how many 4x8 plywood sheets you need for subfloor, cabinets, sheathing, and sheet goods projects.
Formula: (Area ÷ 32) × Waste Factor
Deck Board Spacing Calculator
Calculate deck board spacing, linear feet, and approximate board count for wood or composite decking.
Formula: Area × 12 ÷ (Board Width + Gap)
