Board length planning
Board cut calculator for shelves, rails, and lumber lengths
Plan one-dimensional cuts from board stock with kerf, usable length, purchase count, waste, and a print-ready cut list.
Main workflow
Cut planning workspace
Enter stock, parts, kerf, and rotation rules. Review purchase needs, waste, layout, and a printable cut sheet without a server.
Planning estimate only. Verify final dimensions, site conditions, material defects, and supplier requirements before ordering or cutting.
Project
Mode, kerf, and buffer
Stock dimensions and price drive the purchase list. Sheet mode needs width.
Stock sizes
Stock dimensions and price drive the purchase list. Sheet mode needs width.
Part list
Add parts with positive dimensions and quantity; the optimizer sorts the list for placement.
Why planners use it
- Great for shelving, rails, face frames, and repeat lumber lengths.
- Shows leftover length per board so purchase decisions are easier.
- Keeps save/export actions browser-only.
What to review before ordering
- The cut optimizer is a deterministic planning helper. Verify grain direction, defects, clamps, trim allowance, and saw setup before cutting.
- Kerf and overage are included in the planning math, but real shops should still review the printed list before ordering stock.
Board calculator scope
This route uses the same flagship optimizer in board mode. It is best for one-dimensional cuts where width is already determined by the stock.

Frequently asked questions
Do I need to enter width?
No. Board mode optimizes by stock length.
Is kerf counted?
Yes. Kerf is applied between cuts in each board.
