Free sheet cutting calculator
Plan your sheet cuts in the browser, see the optimised layout, and buy fewer boards. No install, no spreadsheet, any device.

What makes this more than a basic cutting calculator?
A board can be packed more than one way, and the difference shows up in how many sheets you buy. Cutzilla runs a proper optimiser rather than settling for the first arrangement that works: you pick the cutting style that suits how you work, and it does the fiddly packing for you.
Cutzilla gives you two cutting strategies: a rip-first one for clean, edge-to-edge strip cuts that are easy on a table or panel saw, and a tighter one for maximum yield. Every run packs the job with both and keeps the better layout, and each strategy also tries the sheet both ways round and keeps its own winner. The result is fewer sheets bought and less offcut left on the floor, from the same cut list.

From cut list to clean cuts in minutes
No setup, no spreadsheets to wrangle. Enter your parts and let the algorithms do the packing.
Add your sheets & parts
Type them in or import a CSV. Set kerf, grain direction and stock sizes — Cutzilla remembers your common materials.
Run the optimisation
Pick an algorithm or run both. In seconds Cutzilla compares the layouts and selects the one that wastes the least.
Cut with confidence
Follow the visual sequence, print labels for each piece, and export PDF, SVG or CSV. Done before the kettle boils.
Cutting optimisation is free. You pay for the paperwork.
Layout quality is never the thing we hold back — both algorithms, grain direction and multi-sheet layouts are on every plan, including Free. Paid plans add the exports, labels and business tools around them.

A sheet cutting calculator works out how to fit your parts onto full sheets with the least waste, then shows you the layout to cut to. Cutzilla does this in the browser: enter your parts and stock sizes, and it nests them onto as few boards as possible.
Yes. The free plan gives you 5 optimisations a day in the browser with no card required, and no time limit. Paid plans start at $15 a month for clean exports and printable labels, and every new account gets 14 days of everything to try first.
Any sheet good: plywood, MDF, melamine, chipboard, acrylic, and even metal or glass, plus linear stock like bars and timber. You set the exact kerf for your blade and lock grain direction on the parts that need it.
Yes. You set your blade kerf once and Cutzilla builds it into every layout, so the plan you cut to is the plan you measured, with no quiet drift between the screen and the bench.
No. Cutzilla runs entirely in the browser on any device, so there is nothing to download, license per machine, or keep updated. Open it, plan your cuts, and go.
