Calculate wood shrinkage from moisture content changes. Find dimensional change across radial, tangential, and longitudinal grain for common lumber species.
Calculate dovetail joint pin and tail spacing, slope angle, and layout dimensions. Plan half-blind or through dovetails for drawers and boxes.
Calculate lumber weight from board dimensions, wood species density, and moisture content. Estimate load for hauling, shelving, and freight shipping.
This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
Grit steps via geometric progression between start and finish gritThe calculation requires: Starting Grit, Finishing Grit, Number of Steps. Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.

Check the expected unit for each input field (shown as suffix). Converting between imperial and metric units before entering values prevents calculation errors.
When a formula combines multiple measurements, all inputs must use compatible units. Convert everything to the same system (metric or imperial) before calculating.
Plan sandpaper grit steps from rough to final finish. Free online woodworking calculator with instant, accurate results. It applies the calculation formula (Grit steps via geometric progression between start and finish grit).
