Board Cutting Calculator - Optimize Sheet & Panel Layouts

Every Wasted Board Costs You Money

A single sheet of melamine chipboard costs €35–60. A cabinet project needs 12–18 sheets. Cut them without a plan and you will throw away 25–35 % of every sheet — that is 3–6 boards going straight into the skip. Multiply that by 20 projects a year and you are losing €2,000–7,000 annually on material you paid for but never used.

A board cutting calculator solves this in seconds. Enter your stock board sizes, paste your parts list, click optimize — the nesting algorithm packs everything onto the fewest possible sheets and hands you a labeled cutting diagram ready for the saw.

CutOptim is a free online board cutting calculator that handles multiple board sizes, blade kerf compensation, grain direction locking, and offcut reuse. No installation, no signup for your first cuts, and full PDF/DXF export for the workshop floor.

That gap represents real money. On a 15-sheet kitchen project, dropping from 30 % waste to 7 % means you need 3 fewer sheets. At €45 per sheet, that is €135 back in your pocket — from a single project.

How to Use This Board Cutting Calculator

1. Enter your stock board sizes

   Add the width and height of each board or sheet you plan to cut from. Mix full sheets (e.g., 2800 × 2070 mm) with leftover offcuts you want to use up first — the optimizer prefers smaller pieces to save new stock.

2. Add every part you need to cut

   For each piece, enter its width, height, quantity, and a label (e.g., “Cab-03 Left Side”). If the board has a visible grain or veneer, enable grain-lock so the optimizer only places it in the correct orientation.

3. Set blade kerf and edge trim

   Enter your blade kerf — 3 mm for a standard panel saw, 0 mm for CNC with tool compensation. If your boards have rough factory edges, set an edge trim of 5–10 mm per side.

4. Click Optimize and review the layout

   The algorithm packs your parts across the minimum number of boards. Each piece is labeled on the visual diagram. Waste areas are highlighted so you can spot reusable offcuts at a glance.

5. Export for the workshop or CNC

   Download a PDF with labeled cutting diagrams (Pro users: add your company logo), a CSV for material costing, or a DXF for direct CNC machine import.

Who Needs a Board Cutting Calculator?

Cabinet makers and kitchen fitters

A standard kitchen has 15–30 cabinet boxes, each needing 5–6 panels: top, bottom, two sides, back, and shelf. That is 100–180 parts from melamine chipboard. Without optimization, workshops over-order by 2–3 sheets “just in case.” With CutOptim, you know the exact sheet count before placing the order — and parts from two concurrent kitchen projects can share sheets when schedules align.

Furniture workshops and batch producers

Wardrobes, desks, and bookcases share repeating dimensions. The optimizer groups identical parts, rotates for the tightest fit, and often saves a full sheet on every 10-unit batch. Save the project file, reload it next month, adjust quantities, re-optimize — production planning in under a minute.

Shopfitters and exhibition builders

Premium boards (acrylic-faced MDF at €80+, fire-rated panels) make every wasted sheet expensive. Import your CAD cut list, optimize, and send the labeled PDF directly to the CNC operator. No ambiguity, no re-measuring, no delays.

DIY builders

Even a single bookcase with 12 parts benefits. The visual cutting diagram tells you exactly how many boards to buy before you drive to the hardware store — no more guessing, no return trips for “one more sheet.”

Pro Tips for Better Board Cutting Results

• One material per optimization. Run 18 mm white melamine and 16 mm birch plywood separately. Mixed-material diagrams cause errors at the saw.
• Add edge banding thickness. If parts get 0.5 mm or 2 mm edge tape, increase the part dimension by the tape thickness so the finished size is correct after application.
• Label everything. Use clear part names (e.g., “Wardrobe-02 Shelf”) — they appear on the PDF diagram and make assembly foolproof.
• Save projects for repeat orders. When a client changes quantities or a part needs recutting, reload the saved layout and re-optimize instead of starting from scratch.
