4x8 Plywood Cut List Optimizer with Kerf
Load a 48 x 96 inch plywood preset, enter rectangular parts, include kerf, and generate a printable 4x8 plywood cut layout with waste and unplaced-part warnings.
Preset guide
4x8 plywood cut list preset
This page is meant for a common 48 × 96 inch sheet workflow. Use the tool above for the actual layout, then use this module to check the assumptions before you print or cut.
| Setting | Default / example | Why it matters |
|---|---|---|
| Stock size | 48 × 96 in sheet | Matches the common plywood planning size used by this preset. |
| Kerf | 1/8 in example | The blade-width gap can make exact-fit layouts fail. |
| Parts | Cabinet sides, shelves, top / bottom | The default parts show how repeated rectangles are packed. |
| Output | Sheet count, yield, waste, printable diagram | These are planning outputs; verify dimensions before cutting. |
Worked example: why the sample is useful
Start with the 4×8 sample if you only want to see how a plywood layout behaves. Change one part size at a time, regenerate, and watch the sheet count, yield, and unplaced count.
| Step | What to change | What to check |
|---|---|---|
| 1 | Set real blade kerf | The layout reserves cut loss between parts. |
| 2 | Enter finished part sizes | Do not inflate dimensions for kerf. |
| 3 | Generate the layout | Check whether any parts are unplaced. |
| 4 | Review offcuts | Decide whether large offcuts are worth saving. |
When a 4x8 layout is not enough
A 4×8 preset does not know about sheet defects, bowed material, shop handling limits, or whether a factory edge must be trimmed. Add trim margins or split the project into more realistic stock groups when those issues matter.
Common mistakes to avoid
- Using 0 kerf for a saw-cut plywood job.
- Treating the generated diagram as a machine-ready CNC toolpath.
- Forgetting grain direction on visible cabinet or furniture parts.
- Assuming every offcut shown in the diagram will be square and reusable.

How this tool works
Rectangular sheet layout evidence
Plans rectangular parts inside rectangular sheet stock with kerf spacing, optional rotation controls, labels, stock quantities, reusable offcuts, and printable diagrams.
Calculation basis: The live calculator output is the source of truth for placement, waste, unplaced parts, and export tables after the user enters stock size, kerf, and part dimensions.
Privacy model: Calculations run in the browser. Autosave uses localStorage, and share links encode project data in the URL hash instead of uploading project dimensions to a StockCut server.
Verify before cutting
- Measure actual stock width and length before cutting.
- Confirm blade kerf and whether the first trim cut is required.
- Review rotation, grain direction, defects, and edge banding before accepting the layout.
- Check unplaced parts and partial-result warnings before exporting.
Boundaries
- No polygon nesting, circular parts, angle cuts, or CNC toolpath generation.
- DXF output is a planning outline, not machine-ready CAM.
- Results are planning estimates and should be verified against physical material.
