Graph Paper
Free Printable Graph Paper PDF Generator
Build a printable square-grid PDF in your browser — pick the cell size in millimetres, choose a paper size, and download. The grid is drawn to exact metric measurements so a 5 mm cell prints as 5 mm.
When printing, set scaling to Actual Size / 100% / No Scaling. "Fit to Page" will distort the measurements.

About graph paper
Graph paper is a sheet ruled with a regular square grid. The grid acts as a coordinate system you can lean on: every line is the same distance from the next, so you can measure, scale, and align with nothing more than a pencil and a ruler. Engineers, mathematicians, architects, knitters, pixel artists, and tabletop gamers all rely on it for the same reason — it removes the friction of sketching anything that has to be accurate.
When to use it
Use a fine grid (1–2 mm) for plotting data, designing knitting and embroidery patterns, mapping pixel art, or laying out circuit boards. A 5 mm grid is the default for school maths and most note-taking. A 10 mm grid is better for rough planning — floor plans, garden beds, story maps, or anything you want to sketch quickly without counting cells.
The major grid
A second, heavier grid drawn every Ncells helps you count without losing your place. The classic combination is a 2 mm minor grid with a heavy major line every 5 cells (so every 10 mm), which gives you both fine resolution and easy "chunking" at the centimetre. Use the Major every and Major weight controls to tune that.
Printing accurately
Home printers will silently shrink the page unless you tell them not to. Whatever PDF viewer you use, find the option called Actual Size, 100%, or No Scalingand select it. "Fit to Page" or "Shrink to Fit" will scale the grid by a few per cent in the wrong direction, and a 5 mm cell can end up at 4.7 mm. Also keep a margin of at least 5 mm — most printers cannot physically print to the edge of the sheet.
A note on metric and imperial
This generator works in millimetres throughout because that is the unit graph paper is actually drawn in. If you want common imperial sizes, set the cell to 6.35 mm for a quarter-inch grid or 5.08 mm for a fifth-inch grid. The PDF page size will already match standard letter and legal sheets so the printer does not rescale.
Frequently asked questions
What cell size should I choose for graph paper?
5 mm is the most common size and is the default on this generator — it suits maths, note-taking, and general sketching. 4 mm is closer to the classic French Seyès-style grid, 10 mm is good for larger diagrams and rough planning, and 1 mm or 2 mm is useful for precise plotting or technical drawing. If you want imperial sizing, set the page size to US Letter and use 6.35 mm (¼ inch) or 5.08 mm (⅕ inch).
Why do my printed cells come out smaller than I set?
Almost every time, the print dialog is set to "Fit to Page" or "Shrink to Fit" rather than 100%. Most home printers also leave a small unprintable border, so any margin of 0 will be clipped. To get exact sizing, choose "Actual Size", "100%", or "No Scaling" in the print dialog, keep a margin of at least 5 mm, and select the same paper size in the printer settings as in this generator.
Can I make graph paper with both a fine and a bold grid?
Yes — that is what the "Major every" and "Major weight" controls are for. Set "Major every" to the number of small cells you want between heavy lines (for example, 5 to draw a heavy line every centimetre on a 2 mm grid), then increase "Major weight" until the major grid stands out. Set "Major every" to 0 or 1 to disable the bold grid entirely.
Is this graph paper actually free to use?
Yes. There is no watermark, no signup, and no usage limit. PDFs are generated locally in your browser, so nothing is sent to a server. You can use the printed sheets for personal, school, or commercial work without attribution.
Which paper size is best — A4 or US Letter?
Use the paper size your printer is loaded with. A4 (210 × 297 mm) is the standard outside the United States; US Letter (215.9 × 279.4 mm) is the standard inside it. The grid itself will be identical at any size, just trimmed to fit the page. If you mix them up, your printer will likely auto-scale and your cells will not measure what they should.
