Both calculators run independently β change the inputs on either side to compare results.
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.

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.
