Woodworking & Carpentry Calculators
Interactive measurement conversions, precision joinery layouts, and material dimensioning tools optimized for cabinetmakers, builders, and hobbyist woodworkers.
Wood Moisture & Shrinkage Sizer
Predict radial, tangential, and volumetric wood shrinkage as moisture content drops from green/FSP down to EMC (equilibrium moisture content).
Wood Species & Shrinkage Parameters
Expected Shrinkage Output (Red Oak)
Wood is a hygroscopic material that absorbs and releases moisture. Tangential shrinkage (parallel to growth rings) is typically twice as great as radial shrinkage (perpendicular to growth rings). Longitudinal shrinkage is usually negligible.
Lumber does not shrink or expand when moisture levels are above the Fiber Saturation Point (FSP, around 30% moisture content) because only the free water inside cell cavities is leaving. Below 30%, bound water leaves the cell walls, causing cell shrinkage.
