A new web tool allows users to generate custom graph paper directly in their browser, outputting vector PDFs for precise printing. The project, shared on Hacker News, offers instant downloads without requiring logins or watermarks. Users can select from popular grid sizes like 5 mm or 1/4 inch, or create entirely custom layouts.

The generator supports various grid types including dot, isometric, and hexagon, alongside standard lined and Cornell notes formats. All generated sheets maintain true scale, ensuring accuracy when printed at 100%. The tool supports a wide range of ISO A/B/C and US/Imperial paper sizes, making it versatile for different printing needs.

This approach bypasses server-side processing, providing a direct, client-side solution for creating print-ready graph paper. The project emphasizes ease of use with a three-step process: pick or customize, preview live, and download. The output options include both PDF and PNG formats, catering to diverse user requirements for visual aids and technical drawings.
