Woodworking Calculators

9 free, browser-based tools. No account required.

This category brings together the measurements behind furniture making, joinery and workshop projects. Its focus is on timber quantities, board dimensions, cutting allowances and repeatable layouts.

Plan your woodworking calculations

Start with a dimensioned sketch and distinguish finished part sizes from the stock you buy. Keep thickness, width and length in consistent units, and record allowances for trimming and the material removed by each cut. A material estimate and a cutting layout answer different questions: enough total timber does not necessarily mean every required part will fit.

Future calculators in this collection will cover board feet, kerf allowances, spacing and project quantities. For tools available now, visit our construction tools.
