Which square grid paper spacing should I use?
Use 5mm spacing for most math, notes, and technical sketches. Use 1cm spacing for larger handwriting and classroom work, 2mm for fine detail, and 1/4 inch spacing when you need a familiar US graph paper format.
How do I print graph paper at the correct size?
Print the PDF at Actual Size or 100% scale. Avoid Fit to Page when the grid spacing needs to stay accurate.
Can I customize the color, margins, or line width?
Yes. Open the custom generator from any template card to start with that size, orientation, and spacing, then adjust color, margins, line width, and export format.
