2 cm graph paper

A 1 cm grid already reads as fine print to a five-year-old holding a pencil, and it can disappear entirely on a worksheet adapted for a student with low vision or a sheet projected for a whole classroom to see. Doubling the spacing to 2 cm keeps the squares large enough to draw inside confidently, count individually from a few feet away, or laminate as a wall-poster grid — without the lines blurring together the way a fine grid does once it's enlarged.

Because this is built as a vector PDF rather than scanned from a printed original, the 20 mm spacing stays exact regardless of how it's used — print at 100% and it measures true, or scale it up for a display board without the lines thickening or drifting off-square. If 2 cm still isn't large enough, there's no coarser sheet in this set; for finer coordinate work or standard exercise-book maths, the 1 cm sheet is the one to use instead.
