Board Foot Calculator
Calculate board feet from thickness, width, and length. Supports multiple boards and pricing.
Miter Angle Calculator
Find the miter angle for any number of sides. Regular polygons, picture frames, and custom joints.
Dovetail Spacing
Calculate pin and tail spacing for hand-cut dovetails. Even distribution with configurable ratios.
Crown Molding Angles
Miter and bevel angles for crown molding at any spring angle and corner angle. Inside and outside corners.
Wood Shrinkage
Estimate dimensional change from moisture content shifts. Tangential, radial, and longitudinal movement.
About WoodCalc
WoodCalc is a collection of free woodworking calculators designed for carpenters, furniture makers, and hobbyist woodworkers. Every tool runs entirely in your browser — no data is sent to any server, no account is required, and results are instant.
The board foot calculator helps you estimate lumber costs and quantities. The miter angle tool handles regular polygons and custom angles for picture frames, boxes, and trim work. Dovetail spacing calculates even pin-and-tail distribution for hand-cut joints. The crown molding calculator solves compound miter and bevel angles — the math most woodworkers dread. And the wood shrinkage estimator helps you plan for seasonal wood movement in your projects.
All calculations can be shared via URL — just copy the address bar after calculating to send your exact inputs and results to a colleague or save them for later.
