Is this deck lumber linear calculator free?

Yes. The linear cut list optimizer runs in the browser with free-tier daily limits.

Can I use multiple deck lumber stock lengths?

Yes. Enter every stick length you buy — 8 ft, 12 ft, 16 ft decking and joist stock — and compare yield.

How do I set kerf for deck lumber?

Measure once on scrap. For deck lumber, 1/8 in deck saw kerf is a common starting point until tooling changes.

Deck cut list calculator

Deck framing uses linear cuts for joists and often mixed lengths for decking boards. List each length and optimize against purchased stock.

How Cutlistor optimizes deck lumber

The free linear cut list optimizer accepts multiple deck lumber stock lengths, part lengths, quantities, and kerf. Review stick count and yield before you buy.

2×6 calculator Lumber calculator

Mixed lengths

Enter multiple stock lengths if you buy both 8 ft and 16 ft material.

Deck framing vs decking boards

Decking is 1D along board length — not sheet nesting.

Component	Typical stock	Optimizer
Joists	2×8/2×10 sticks	Linear
Deck boards	5/4 or 2× decking lengths	Linear
Rail posts	Long sticks	Linear

Step-by-step deck lumber linear workflow

List every finished deck lumber length and quantity. Enter stock lengths you actually buy — 8 ft, 12 ft, 16 ft decking and joist stock. Set kerf to 1/8 in deck saw kerf.

Run the optimizer and read stick count plus offcuts. Compare 12 ft vs 16 ft decking boards on the same cut list when price per foot differs.

For mixed jobs, run panels in the sheet optimizer and sticks here. Link both PDFs in the job folder.

Kerf and stock lengths for deck lumber

Deck jobs mix joists (often 2×8 or 2×10) and decking boards — both are 1D with different stock lengths.

Enter multiple board lengths if the yard stocks 8, 12, and 16 ft decking.

Stock option	Typical use
16 ft decking	Fewer board joints
12 ft joist stock	Common joist bundle
8 ft	Short spans, stairs

Worked example: rectangular deck frame

Twelve joists at 14 ft plus forty 16 ft deck boards — run joists and decking as separate material codes with appropriate stock rows.

Linear cut list optimizer packing deck lumber lengths onto stock bars with a cut diagram — The optimizer packs your deck lumber lengths onto each stock bar and shows the leftover offcut per stick.

Import, export, and verification

Import linear CSV or XLSX from /samples/cutlist-import/ when Excel already holds deck lumber lengths.

Export PDF cut sequences for the crew. Paid plans add saved projects and mitered ends on linear parts in the dashboard.

Free anonymous use includes 3 calculations per day, up to 20 part rows, and CSV imports of up to 5 rows.

Before you cut deck lumber: checklist

Confirm deck lumber stock length matches the bundle on order. Confirm kerf for your cutting process.

Link sheet and linear PDFs when one job uses both material forms.
