Calculators & workshop utilities
Seven browser-based tools for the maths that woodworking keeps throwing at you: planning cuts, buying materials, estimating finish and working out angles. Nothing is uploaded and nothing is stored.
Utilities
Plan the job before you buy the material
Cut Optimizer
Plan every part across your sheet goods and see exactly where each cut falls, with a live layout diagram.
Board Foot & Material Calculator
Convert any stack of boards into board feet, weight and estimated cost, with multi-line totalling.
Finish & Coverage Estimator
Work out how much finish you need, how many coats, and how long each one takes to dry at your temperature.
Wood Database
Sort and filter 18 species by hardness, density, cost, stability and outdoor suitability, and compare up to three side by side.
Calculators
Angles, screws and realistic time estimates
Miter & Bevel Calculator
Work out the exact saw settings for any corner angle or polygon, including compound mitres.
Screw & Pilot Hole Calculator
Get the pilot, clearance and countersink diameters right so the screw holds without splitting the wood.
Project Time Estimator
Plan a realistic schedule by breaking a build into measuring, cutting, assembly and finishing hours.
Hands-on
Or work a board directly
The workshop bench simulates a real wood surface. Sand it, plane it, saw it, stain it and wax it, and see how each operation changes the material.
