How to Optimize Sheet Cuts — Step-by-Step Guide
Getting the most from every sheet of material starts with a solid plan. Follow this guide to reduce your workshop's scrap rate and improve efficiency.
Why Sheet Cut Optimization Matters
Every square millimeter of material you throw in the bin is money lost. By learning to optimize sheet cuts properly, workshops typically reduce their scrap rates from 20% down to under 10%. It also guarantees consistency and dramatically speeds up the time spent at the saw.
Step 1: Measure Your Stock
Record all your available raw materials. Don't just count the fresh 2440×1220mm sheets—make sure to log any large, reusable offcuts from previous jobs. Using offcuts first is the fastest way to save money. If you are specifically dealing with plywood, a plywood cutting calculator can help with inventory tracking.
Step 2: List All Required Pieces
Write down the dimensions and quantities of every part you need for the project. For complex projects, use labels (like "Base Cabinet Side" or "Top Shelf") so you know what each piece is after it's cut.
Step 3: Account for Blade Kerf
The thickness of your saw blade is called the kerf. Typically 3–4mm, this material is turned into dust during the cut. If you ignore it, your final pieces will be too small. Example: 10 cuts × 3mm = 30mm of lost material across a sheet.
Step 4: Try Manual Layout
Historically, woodworkers drew rectangles on graph paper to plan their cuts. While this is better than guessing at the saw, human brains struggle with 2D bin packing. We naturally try to align edges, which rarely yields the optimal nesting pattern.
Manual Layout Result
- Usually leaves jagged, unusable scraps
- Takes too much time to calculate
- High risk of math errors
Step 5: Use Software Optimization
The modern approach is to use a cut list optimizer. You simply input the dimensions, and the software evaluates thousands of permutations in milliseconds to find the tightest fit.
CutWize Result
- Maximizes material yield
- Automatically accounts for kerf
- Generates printable cutting maps

Step 6: Track Your Offcuts
When the optimization finishes, it usually leaves a few large remnant pieces. Log these usable offcuts into your inventory so they can be prioritized for the next job.
