Woodworking
Wood Expansion Calculator
Estimate how much a wood board will expand or contract across its width as humidity (and therefore moisture content) changes. Essential for furniture makers and flooring installers designing for seasonal wood movement.

Woodworking
Wood Shrinkage Calculator
Predict the dimensional change of a wood board as moisture content drops from initial to final equilibrium, using the species-specific shrinkage rate. Useful for milling green lumber, planning joinery clearances, and avoiding warping or splitting in finished work.
