Eagle CAD Free Maximum Size Explained: Understanding the Limits of Eagle CAD Free VersionEagle EnthusiastSep 05, 2025Table of ContentsTips 1:FAQTable of ContentsTips 1FAQFree Smart Home PlannerAI-Powered smart home design software 2025Home Design for FreeEagle CAD, a popular PCB design software, offers a free version (often referenced as the Eagle Free license) that comes with some important limitations—most notably, the maximum size your designs can be. Understanding these limitations upfront helps hobbyists and professional designers plan their projects efficiently.As of Autodesk’s current licensing terms, Eagle Free allows you to design PCB layouts with a maximum board area of 100mm x 80mm (approximately 3.9" x 3.15"). Additionally, you’re limited to just two signal layers (top and bottom). While these limits are restrictive for advanced or multi-layer projects, they’re generally adequate for simple circuits, prototypes, or small devices such as Arduino shields and sensor modules.In my experience as a designer, spatial constraints like those in Eagle Free can directly influence every stage of a layout—component placement, trace routing, and the aesthetic organization of your schematic. Creativity within boundaries is a cornerstone of good design, whether you’re working with electronics or planning out your living room. If your project requirements grow, you might want to explore how similar boundary management and space optimization principles apply in fields like room planning, where every square inch counts and smart solutions let you do more with less.Tips 1:If you find yourself consistently running into Eagle Free’s workspace limitations, consider breaking your design into modular sections that connect via headers or jumpers. This modularity not only makes large projects manageable but also mimics effective zoning strategies in design—dividing complex spaces into functional areas for easier organization and future expansion.FAQQ: What is the maximum board size in Eagle CAD Free?A: The maximum board size allowed is 100mm x 80mm (approximately 3.9" x 3.15").Q: How many layers can Eagle Free designs have?A: Eagle Free supports up to 2 signal layers (top and bottom).Q: Can I use Eagle Free for commercial projects?A: Officially, Eagle Free is intended for hobbyists, makers, and non-commercial use only.Q: What happens if my PCB exceeds the size limitation?A: Eagle will not allow you to define a PCB outline larger than 100mm x 80mm in the Free version, so you cannot proceed until you reduce the size.Q: Are there ways to work around Eagle Free’s limitations?A: You can create smaller, modular boards and connect them together, or consider upgrading to a paid license for larger or multi-layer boards.Home Design for FreePlease check with customer service before testing new feature.
