Free sheet-goods planner
Plywood & sheet-goods cut list optimizer
Turn mixed-size parts into labeled, kerf-aware sheet layouts. Lock visible grain, trim damaged edges, estimate stock cost, and keep the entire calculation in your browser.

Planning estimate: this deterministic guillotine-style heuristic favors rectangular saw-friendly splits. It does not guarantee the global mathematical optimum or prescribe a safe machine sequence. Verify every dimension and operation.
A result you can audit
How this cut list optimizer works
The planner expands every quantity into an individual rectangular part, sorts the constrained pieces, and tests permitted orientations against the available rectangles on each sheet. Every placement creates new guillotine-style rectangles after the entered blade kerf is removed.
It favors low-waste placements with repeatable tie-breaking. That makes the result deterministic, but it remains a heuristic best-found plan—not proof of the global optimum. Sheet cutting is a combinatorial problem, and practical layouts also depend on the equipment and handling constraints the browser cannot see.
What is included
- Common sheet presets plus measured custom dimensions
- Imperial fractions or metric decimal measurements
- Blade kerf and equal edge-trim allowance
- Per-part quantity, labels, rotation, and grain lock
- Labeled sheet diagrams, part yield, stock cost, CSV, and print view
Worked starting point
A small base cabinet on one screen
The sample includes two grain-locked cabinet sides, a bottom, two shelves, and stretchers on a 48 × 96 inch sheet. Change any dimension and the plan rebuilds immediately, so the example is evidence you can inspect—not a static claim.

Cut list optimizer questions
What does a cut list optimizer do?
It places entered finished rectangles onto stock sheets while respecting dimensions, quantity, blade kerf, edge trim, rotation, and grain rules. SawNest then labels every placed and unplaced part for review.
Is this plywood cut list optimizer free?
Yes. SawNest runs in the browser without an account and includes printable layouts, CSV export, stock-cost estimates, and public benchmark cases.
Does the optimizer guarantee the absolute minimum number of sheets?
No. Sheet nesting is a combinatorial problem. SawNest uses repeatable guillotine-style heuristics and reports the best candidate it finds, but every result still needs an independent project and shop-safety review.
