Cut your material with the least waste
Tell Board Beaver the sheet sizes you can buy and the parts you need. It packs them onto the fewest sheets with clean guillotine cuts — kerf and grain included. Free, in your browser, nothing uploaded.
No signup. No watermark. Your cut list never leaves your browser.
Least-waste layouts
Enter stock and parts; get the fewest sheets and a clear per-sheet cutting diagram in a click.
Kerf & guillotine
Blade width is subtracted at every cut, and layouts use straight edge-to-edge cuts a panel or table saw can actually make.
Grain aware
Lock grain direction per part, or let parts rotate 90° for a tighter fit — your call.
Private & free
No account, no upload. The optimizer runs in your browser; print the layouts and cut list for the shop.
How it works
- Enter your stock The sheet or board sizes you can buy — 2440×1220 plywood, a 20-ft length of tube, whatever you use. Add a price to see material cost.
- List your parts The pieces you need, with quantities. Mark any part non-rotatable to respect grain.
- Set your kerf Your blade width, so every cut is accounted for.
- Optimize Get the fewest sheets, a diagram for each, waste %, and a cut list — print it and head to the saw.
Frequently asked questions
Is Board Beaver free?
Yes — completely free, with no account and no watermark. It's ad-supported. Optimize as many cut lists as you like and print the layouts.
Does my cut list get uploaded anywhere?
No. The optimizer runs entirely in your browser — your sizes never leave the page and nothing is stored on a server.
Does it account for the saw blade kerf?
Yes. You enter your kerf (blade width) and it's subtracted at every cut, so the layout reflects the material each cut actually removes.
Can it handle grain direction?
Yes. Turn off rotation for a part (or globally) to lock its grain direction; leave it on to let the optimizer rotate parts 90° for a tighter fit.
What materials does it work for?
Any sheet or linear stock cut with straight edge-to-edge (guillotine) cuts — plywood, MDF, melamine, sheet metal, acrylic, glass, and boards or tube by length.
