Free Printable Graph Paper
Square-grid paper you can customize and print to PDF — choose squares per inch or millimeter grids, add heavier major lines, and switch between Letter and A4. Free, no signup.
Tip: when printing, set Margins to “None” and Scale to 100% for an exact-size grid.
About this free printable graph paper
This generator makes free printable graph paper as a PDF — an even square grid you can print at home, school or the office. Unlike a fixed PDF download, you choose the exact grid: squares per inch (4, 5, 8 or 10) or a metric millimeter grid (2 mm, 5 mm or 1 cm), optional heavier major lines, the line color, and the page size. Everything is drawn as crisp vector graphics, so the grid stays sharp and prints at its true size on both Letter and A4.
Common graph paper sizes
| Grid size | Square width | Best for |
|---|---|---|
| 4 squares / inch (1/4″) | 6.35 mm | The classic US math grid |
| 5 squares / inch | 5.08 mm | Engineering and lab pads (turn on major lines) |
| 8–10 squares / inch | 3.18–2.54 mm | Fine grids for detailed plots |
| 5 mm | 5 mm | Standard metric grid; bullet journaling |
| 10 mm (1 cm) | 10 mm | Metric math and larger diagrams |

Graph paper vs grid paper
They are the same square grid. “Graph paper” is the usual name in math and science, while “grid paper” is often used for note-taking, design and handwriting in Asian scripts. This tool covers both — set the square size you need.
What people use it for
Plotting functions and coordinates, engineering and architecture sketches, pixel art and isometric drawing, cross-stitch and knitting charts, bullet-journal layouts, board-game maps, and tidy handwriting. Because you can set any square size and print instantly, it replaces a drawer full of different pads.

Frequently asked questions
What is the standard size of graph paper?
The most common US graph paper is 4 or 5 squares per inch; engineering pads often use 5 squares per inch. In metric countries, 5 mm and 10 mm (1 cm) grids are standard. This tool lets you pick any of these.
What is the difference between graph paper and grid paper?
They are essentially the same thing — a square grid. 'Graph paper' is the common name in math and science; 'grid paper' is often used for general note-taking and design. Both are generated by the same square-grid tool here.
How do I save graph paper as a PDF?
Choose your square size and paper size, then select Print / Save as PDF. In the print dialog, choose Save as PDF, match Letter or A4, set the scale to 100% and turn browser margins and headers/footers off. The saved PDF contains the paper without the website controls.
Should I use inch or centimeter squares?
Use inch-based squares (4 or 5 per inch) for US math and engineering work, and millimeter/centimeter grids (5 mm or 10 mm) for metric work or bullet journaling. Switch the grid-size control to whichever you need.
What are the heavier 'major' lines for?
Major lines are darker lines drawn every few squares (commonly every 5). They make it easier to count squares and read coordinates at a glance. Turn them on or off with the major-line control.
Is it free, and does it work on Letter and A4?
Yes — completely free, no signup. Choose US Letter (8.5 × 11 in) or A4, portrait or landscape, and the grid prints at its exact size.
