Sheet yield calculator
Sheet yield measures usable part area versus purchased panel area. Cutlistor shows yield as you edit parts so you can compare layout methods and reduce scrap.
How Cutlistor nests sheet stock
Use the free sheet cut list optimizer to enter sheet stock stock sizes, parts, kerf, and optional grain or edge-banding notes. You will see nested layouts and can export a PDF for the shop.
Improving yield
Try different optimization methods, rotate parts where grain allows, and verify kerf matches your blade setup.
What good yield looks like
Compare yield between methods on the same part list, not across unrelated jobs.
| Job type | Typical yield range | Action if low |
|---|---|---|
| Simple casework | 70–85% | Check kerf and grain locks |
| Many small parts | 65–80% | Try least waste method |
| One oversized panel | Can drop sharply | Split job or stock size |
Step-by-step sheet stock sheet workflow
Start with the sheet stock sheet SKU you actually purchase — any purchased panel rectangle. Add every finished part as width × height × quantity. Set kerf to your measured kerf so the optimizer subtracts realistic blade loss for sheet stock.
Run the layout and read sheet count plus yield before buying. If yield looks low on sheet stock, check grain locks, mixed thicknesses, or whether compare methods to improve yield fits your crew better.
Export the PDF when the diagram matches shop habits. If a dimension changes, edit the row and recalculate — the sheet stock nest refreshes immediately.
Layout methods for sheet stock
Cutlistor offers multiple sheet strategies because no single algorithm wins every sheet stock job. Rips and rows suits table-saw-first shops. Fewest sheets pushes yield when sheet stock cost dominates. Router / CNC layout helps dense packs when spoilboard spacing is set.
Sheet yield = usable part area ÷ purchased panel area. Cutlistor shows yield live as you edit parts.
| Layout method | Best for sheet stock |
|---|---|
| Fewest sheets / least waste | Maximize yield % |
| Rips & rows | Trade yield for floor speed |
| Neat grid | Moderate yield with simple handling |
Worked example: improving yield on a casework batch
If yield is 68% on melamine, try allowing rotation on hidden parts, verifying kerf, or switching from rips and rows to least waste — recalculate in seconds.
Import, export, and verification
Import CSV or XLSX from /samples/cutlist-import/ when your sheet stock cut list already lives in a spreadsheet. Group rows with material codes when you buy multiple sheet stock SKUs.
Export kerf-aware PDF cut plans for the floor. Paid plans add saved projects, stock inventory, AI plan scanning, and 3D CAD import (glTF, GLB, Collada).
Free anonymous use includes 3 calculations per day, up to 20 part rows per session, and CSV/XLSX imports of up to 5 rows.
Before you cut sheet stock: checklist
Confirm sheet stock stock size matches inventory. Confirm kerf matches today's blade or bit.
Split mixed jobs: panels in the sheet optimizer, sticks in the linear optimizer.
FAQ
- Is this sheet stock calculator free?
- Yes. The sheet cut list optimizer runs in your browser with daily limits. Accounts unlock saved projects and higher caps.
- What sheet sizes work for sheet stock?
- Enter any rectangle you purchase — any purchased panel rectangle. Match the delivery note, not a generic label.
- Does kerf matter on sheet stock?
- Yes. Set kerf to your measured kerf. Underestimating kerf on dense sheet stock nests can shift sheet count.
