How It Compares
The 1/4 inch grid is the US standard. If you need metric sizing, the 5mm grid (0.197 inch) is the closest alternative. For larger, easier-to-read squares, consider 1/2 inch graph paper.
Printing Tip
Always print at 100% scale (Actual Size) — never use "Fit to Page" as this will distort the grid dimensions and the squares will no longer measure correctly.
