5mm Graph Paper
5 mm graph paper is the metric standard used in most of the world — five millimeters per square, with a bolder line every centimeter. Generate it on A4 or Letter and print or download a vector PDF.
What is 5mm graph paper?
- Each minor square is 5 millimeters on a side — half a centimeter.
- A heavier line every 2 squares marks a 1 cm boundary, making it easy to read off measurements in centimeters.
- On A4 (210 × 297 mm), the printable area gives you roughly 36 squares across and 52 down, depending on your margins.
What is it good for?
- Metric math and physics homework where measurements are in centimeters.
- Lab notebooks where you need to plot data on a millimeter-friendly grid.
- Sketching, planning, and pattern design at a clean half-centimeter scale.
- Bullet journaling at a denser pitch than the usual 5 mm dot grid.
5 mm vs 4 mm vs 1 cm
- 5 mm — the metric default; pairs naturally with a 1 cm major line.
- 4 mm — common in European school notebooks; slightly denser.
- 1 cm — coarser; good for younger students or large-format work.
- 1 mm (millimeter paper) — very fine; best for precise scientific plots.
Frequently asked questions
How many squares per centimeter is 5mm graph paper?
Two. Each minor square is 5 mm on a side, so two of them fit across one centimeter.
What paper size should I use?
A4 (210 × 297 mm) is the natural choice for 5 mm graph paper. Letter works too; the grid simply has different totals across and down.
Will it print at exactly 5 mm?
Yes, as long as you print at 100% scale. Disable "fit to page" so the squares stay true to size.
Can I switch the major line to every 5 squares for a 2.5 cm major?
Yes. The "major every" value is editable in the generator — set it to 5 for a 2.5 cm major boundary.
Is 5 mm graph paper the same as A4 graph paper?
Often yes — most A4 graph paper sold in stores uses a 5 mm grid. This generator lets you change either independently.
