What is a cut list calculator?

A cut list calculator is a tool that takes a list of parts you need to cut and figures out the most efficient way to cut them from your stock material. Woodworkers, cabinet makers, and DIY builders use cut lists to turn 4x8 plywood sheets, MDF panels, or 2x4 lumber into finished project parts with as little waste as possible.

The terms cut list calculator, cut list generator, cutlist optimizer, and cutting list calculator all describe the same kind of tool. Some shops drop the space and write “cutlist”; some call it a “board cut list” for lumber projects or a “sheet cutting plan” for plywood. CutListCalc handles all of those workflows in one tool.

Behind the scenes, a cut list optimizer runs a 2D bin-packing algorithm. It tries thousands of possible arrangements with rotation, accounts for saw blade kerf on every cut, and returns the layout that uses the fewest sheets. For lumber and linear stock the same idea collapses to one dimension - the 1D Linear mode does the math for boards, trim, pipe, and bar stock.

Every extra sheet is money in the bin

A typical cabinet project has 30-50 parts cut from 4×8 plywood sheets at $45-80 each. Without optimization, you buy 1-3 extra sheets per job. That's $100-250 wasted - per project.

CutListCalc pays for itself on the first cut.

Materials and stock sizes supported

The optimizer works with any rectangular sheet good or any linear stock. Pick the material in the Stock panel; CutListCalc preselects realistic kerf and sheet dimensions for each one.

Plywood

Standard 4x8 ft (2440x1220 mm) at most home centers; baltic birch is sold in 5x5 ft (1525x1525 mm) and 4x8 sheets. Hardwood plywood, sanded plywood, and CDX share the same dimensions. Plywood cut calculator · sheet size guide.

MDF

Most MDF is sold 4x8 ft in 1/2”, 3/4”, and 1” thicknesses. Dust is heavy on cuts - some shops bump kerf up to 4 mm to avoid binding. MDF cut calculator.

Melamine

Pre-laminated particleboard, common in cabinets. Standard 49x97” oversized sheets give you trim allowance for chip-out. Melamine cut calculator.

OSB and particleboard

OSB ships 4x8 in 7/16”, 15/32”, 23/32”. Particleboard 4x8, often with melamine face. OSB calculator · particleboard calculator.

Lumber and linear stock

Switch the optimizer to 1D Linear mode for boards, dimensional lumber (2x4, 2x6, 2x8 in 8/10/12/16-foot lengths), trim, pipe, conduit, fence rails, or steel bar. Same algorithm, one dimension. Linear cut calculator.

Acrylic, glass, sheet metal

Any rectangular sheet works. Set custom stock dimensions and kerf to match your saw or scoring tool.

Questions

Under the hood, CutListCalc runs a 2D bin packing algorithm (First Fit Decreasing with rotation) to figure out the most efficient way to cut your parts from stock sheets. You enter the sheet sizes and your parts list, and the optimizer returns a cutting plan that minimizes waste. For typical projects up to 100 parts, the results are ready in under 2 seconds.
All three describe the same tool. A cut list calculator computes how many sheets you need; a cut list generator produces a labelled parts list; a cut list optimizer arranges the parts on the sheets with the least waste. CutListCalc does all three in one pass.
Cutlist (one word) and cut list (two words) refer to the same thing: a list of parts to be cut from stock material. We rank for both spellings and the search results are identical.
Yes. Switch the optimizer to 1D Linear mode for boards, dimensional lumber (2x4, 2x6, 2x8), trim, pipe, bar stock, or fence rails. The same packing logic applied to a single dimension.
Any rectangular sheet material: plywood, MDF, melamine, OSB, particleboard, acrylic, glass, sheet metal. You can also use it for linear stock like lumber, boards, pipes, and bars using our 1D cutting optimizer.
CutListCalc runs in any modern browser, so it works on macOS, Windows, Linux, ChromeOS, iOS, and Android with no install. Most desktop cut list software is Windows-only - this is the cross-platform alternative. More on cut list software.
Yes, completely free. No account required, no limits, no watermarks. Just open the optimizer, enter your parts, and get cutting diagrams. We'll add paid features down the road, but the core tool will always be free.
Yes. The default kerf is 3.2mm (⅛"), which is standard for most table saw blades. You can set a custom kerf width for any blade type.
Absolutely. CutListCalc is fully responsive and works on any device with a browser. Enter parts at your desk, pull up the cutting diagram on your phone at the saw.
CutListOptimizer is a capable tool, but it was built in 2015 and stores data in browser cookies. CutListCalc offers a modern interface, mobile support, project saving, project templates, and reliable cloud-based storage for your cut lists.
