Is this hardboard 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 hardboard?

Enter any rectangle you purchase — 2440×1220 mm thin panel stock. Match the delivery note, not a generic label.

Does kerf matter on hardboard?

Yes. Set kerf to 2–3 mm fine blade — thinner than plywood setups. Underestimating kerf on dense hardboard nests can shift sheet count.

How Cutlistor nests hardboard

Use the free sheet cut list optimizer to enter hardboard stock sizes, parts, kerf, and optional grain or edge-banding notes. You will see nested layouts and can export a PDF for the shop.

Thin panels

Verify kerf is smaller than on thick plywood setups.

Thin panel kerf

Use a finer kerf value than thick plywood jobs. Verify on scrap — thin panels chip if feed rate is wrong.

Smaller kerf than 18 mm ply defaults
Support sheet fully during cutting
Separate thickness in material code

Step-by-step hardboard sheet workflow

Start with the hardboard sheet SKU you actually purchase — 2440×1220 mm thin panel stock. Add every finished part as width × height × quantity. Set kerf to 2–3 mm fine blade — thinner than plywood setups so the optimizer subtracts realistic blade loss for hardboard.

Run the layout and read sheet count plus yield before buying. If yield looks low on hardboard, check grain locks, mixed thicknesses, or whether neat grid for pegboard-style layouts fits your crew better.

Export the PDF when the diagram matches shop habits. If a dimension changes, edit the row and recalculate — the hardboard nest refreshes immediately.

Layout methods for hardboard

Cutlistor offers multiple sheet strategies because no single algorithm wins every hardboard job. Rips and rows suits table-saw-first shops. Fewest sheets pushes yield when hardboard cost dominates. Router / CNC layout helps dense packs when spoilboard spacing is set.

Hardboard and pegboard are thin — kerf is smaller but still matters on dense nests.

Layout method	Best for hardboard
Neat grid	Pegboard and backing panels
Fewest sheets / least waste	Large hardboard batches

Worked example: backing panels for cabinets

Six 600×400 mm hardboard backs on 3 mm stock — nest on full sheet, use fine kerf, export PDF for batch cutting.

Import, export, and verification

Import CSV or XLSX from /samples/cutlist-import/ when your hardboard cut list already lives in a spreadsheet. Group rows with material codes when you buy multiple hardboard 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 hardboard: checklist

Confirm hardboard 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.
