What grid size should I use?

For math and general use, 1/4 inch (about 6.35mm) or 5mm grid is common. For larger writing or sketching, 10mm or 1/2 inch can work better. Engineering and technical work often uses 1/4 inch with bold index lines. You can pick the grid size in the editor and see a preview before downloading.

Can I use this for technical drawings?

Yes. Grid paper is well suited for technical drawings, engineering sketches, and architectural plans. The grid helps keep scale and proportions consistent. Many students and professionals use our printable graph paper for coursework and design. You can choose the grid density and line weight in the editor.
