Planning notes
Start with the measurement this calculator asks for, then use related length, area/volume, roof, stair, material, waste, or cut-planning tools only when the job needs them. Inputs and results stay in the browser.
Paste one length × quantity per line, choose stock length and kerf, then inspect a browser-local first-fit stock estimate and cut summary.
Enter one length × quantity per line. Lengths may use feet/inches, inches, mm, cm or meters.
| Stock piece | Cuts | Remaining |
|---|
Cross-check cuts, kerf, stock count, utilization, waste and remaining material.
| Board | Used | Leftover | Utilization |
|---|
Rebuild the visible project math independently, then perturb the field measurements to expose a min/base/max envelope before cutting or ordering. This is a planning cross-check, not structural engineering, code approval, or supplier certification.
Use the exact calculator first, then stress-test realistic field measurement and rounding tolerance before a cut or purchase. Keep structural design, code approval and supplier specifications outside the browser estimate.
