Woodworking Cut Plan Generator｜Optimize Your Plywood & Sheet Layout

This tool helps woodworkers and DIY enthusiasts plan the most efficient way to cut parts from a large sheet of wood, like plywood or MDF. It automatically arranges your required parts to minimize waste, calculates the material yield, and provides a visual layout you can download and take to your workshop.

💡 Tool Overview

• Automatic Layout Optimization: Simply input your part list, and the tool generates a visual cut plan, arranging the pieces to maximize material usage.
• Material Yield Calculation: Instantly see what percentage of your board is being used effectively, helping you make informed decisions and reduce scrap.
• Accurate Kerf Adjustment: Accounts for the thickness of your saw blade (the kerf), ensuring your final parts are cut to the precise dimensions you need.
• Visual Plan Export: Download the generated layout as a high-quality PNG image. Perfect for referencing on a tablet or printing out for use in the workshop.
• Common Size Presets: Quickly start with standard North American sheet good sizes, such as the ubiquitous 4x8 ft plywood.

🧐 Frequently Asked Questions

Q. What is "yield"?

A. Yield is the percentage of the source panel that is used for your actual parts. A higher yield percentage means less material is wasted. Aiming for a high yield saves money and resources.

Q. What is "saw kerf" and why is it important?

A. The "kerf" is the width of the material that is removed by a saw blade during a cut. For example, a standard table saw blade in North America typically has a kerf of 1/8 inch. Including this value in the calculation is crucial for accuracy, as it prevents your final pieces from being slightly too small after multiple cuts.

Q. Are the parts automatically rotated for a better fit?

A. Yes. The algorithm will automatically try rotating parts by 90 degrees if doing so allows for a tighter and more efficient layout. This is done behind the scenes to maximize your material yield without any manual input.

Q. What do the preset buttons like "Standard (4x8 ft)" mean?

A. These are presets for common sheet goods used in North American woodworking and construction. The "Standard (4x8 ft)" preset automatically sets the board dimensions to 48 inches by 96 inches. Other presets like "Half Sheet" (24x96 inches) or "Quarter Sheet" (48x48 inches) are also available to quickly match the material you buy from your local hardware store.

📚 Fun Facts about the "Nesting Problem"

The challenge of fitting irregular shapes onto a single sheet with minimal waste is a classic computer science puzzle known as the "Nesting Problem" or "Bin Packing Problem." This tool uses a simplified algorithm to solve this challenge for rectangular parts. In large-scale manufacturing, from shipbuilding to clothing production, companies use highly advanced nesting software to optimize material cutting. These systems can save millions of dollars by reducing waste by just a few percentage points. This simple browser-based tool brings the core principle of that powerful industrial optimization right to your personal workshop.
