Plywood & Sheet Cut List Optimizer

Saw kerf is the strip of material removed by the blade. A nominal 1/8-inch blade does not leave two finished pieces touching; the cutting path consumes roughly 0.125 inch between them. Metric blades are often described by a 3mm kerf, but the real cut can vary with blade plate thickness, tooth set, runout, feed, and material movement.

Measure a test cut with the exact blade and machine before committing expensive stock. Enter that measured kerf here, then add any separate allowance needed for factory-edge removal, squaring, sanding, jointing, or final trimming. The visual gap between rectangles represents kerf only. It does not reserve a perimeter trim automatically.

This plywood cut list generator free workspace uses a larger-parts-first shelf strategy. That keeps the result fast and understandable in the browser. It is an optimisation aid rather than a guarantee of the mathematical minimum, so compare the proposed sheets with reusable offcuts already in the shop.

Wood grain gives a panel a visible direction and can also affect stiffness, movement, and appearance. Enable Grain locked when the entered length must follow the long direction of the stock sheet. The optimizer will keep that part orientation fixed. Turn the lock off for parts that may rotate 90 degrees without affecting the project.

A lumber cut optimizer for sheet goods should be reviewed in the order the work can actually be cut. Long rip cuts may need to happen before crosscuts, while a track saw, panel saw, table saw, or CNC router imposes different support and access limits. Labels in the canvas identify each rectangle; rotated parts carry an R marker.

The same 2D cut list calculator can provide an early estimate for acrylic, foam, laminate, and rectangular sheet metal panels. For a sheet metal panel nesting tool, enter the true machine gap and keep grain locked when surface direction matters. Production metal work may also require bend deductions, rolling direction, tabs, common-line rules, and toolpath clearance that this rectangular planner does not calculate.

Finally, inspect the waste percentage with judgement. Large continuous offcuts can remain valuable even when counted as waste, while narrow strips may be unusable. Save useful remnants with their measured dimensions and rerun the plan using those remnants as custom stock before buying another full sheet.
