Is this trim and molding linear calculator free?

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

Can I use multiple trim and molding stock lengths?

Yes. Enter every stick length you buy — 12 ft, 16 ft, or 3600 mm primed bundles — and compare yield.

How do I set kerf for trim and molding?

Measure once on scrap. For trim and molding, 2.5 mm fine-tooth miter saw is a common starting point until tooling changes.

Trim cut list calculator

Finish carpentry trim behaves like a linear cut list: many short pieces from fewer long sticks. A trim cut list calculator keeps you from opening extra bundles after the first miscut.

How Cutlistor optimizes trim and molding

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

Lumber calculator Length nesting

Cope and miter reserves

Add small reserves in part lengths if your process needs back-cuts or minor adjustments - the optimizer will still show how stock is consumed.

Cope, miter, and reserves

Enter finished lengths after your standard allowances. The optimizer shows stock consumption from your numbers.

Step-by-step trim and molding linear workflow

List every finished trim and molding length and quantity. Enter stock lengths you actually buy — 12 ft, 16 ft, or 3600 mm primed bundles. Set kerf to 2.5 mm fine-tooth miter saw.

Run the optimizer and read stick count plus offcuts. Compare 12 ft vs 16 ft molding bundles 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 trim and molding

Trim jobs have many short pieces from few long sticks — kerf and cut order matter for crown and base runs.

Add cope and miter reserves in finished lengths if your process needs them.

Stock option	Typical use
12 ft bundle	Base and casing
16 ft bundle	Long wall runs, fewer splices
Primed MDF 3600 mm	Metric finish carpentry

Worked example: baseboard wall run

Twenty-two pieces from 4 ft to 9 ft on 12 ft primed base with 2.5 mm kerf — optimizer sequences cuts to minimize opened bundles.

Import, export, and verification

Import linear CSV or XLSX from /samples/cutlist-import/ when Excel already holds trim and molding 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 15 part rows, and CSV imports of up to 5 rows.

Before you cut trim and molding: checklist

Confirm trim and molding 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.
