Wood Calculators
Free tools for woodworkers, lumber buyers, and wood professionals. Calculate board feet, estimate weights, predict shrinkage, and more.
Board Foot Calculator
Calculate board feet from lumber dimensions. Essential for pricing and estimating hardwood lumber quantities.
Wood Weight Calculator
Estimate lumber weight using species-specific density data from our database of 500+ wood species.
Shrinkage Calculator
Predict dimensional changes during drying. Calculate shrinkage based on species, cut orientation, and target moisture content.
Moisture Strength Adjuster
Adjust mechanical properties for moisture content. Uses FPL Wood Handbook data and standard adjustment factors.
About Our Calculators
All calculators use industry-standard formulas and data from authoritative sources including the USDA Forest Products Laboratory Wood Handbook. Species-specific data comes from our database of 550+ verified wood species.
Unit Support
Toggle between imperial (inches, feet, pounds) and metric (mm, meters, kg) units. Results are displayed in both systems for easy reference and international use.

Board Feet Explained
A board foot (BF) is the standard unit for measuring hardwood lumber in North America. One board foot equals a piece of wood 1 inch thick, 12 inches wide, and 1 foot long (144 cubic inches). Our calculator handles any dimensions and supports quantity calculations for multi-board orders.
Why Moisture Content Matters
Wood properties change significantly with moisture content. Strength increases as wood dries below the Fiber Saturation Point (~28% MC). Understanding these changes is critical for structural applications, furniture making, and proper wood selection.
