Graph Paper Generator
Choose a grid type, spacing and paper size, see the sheet update live, and download a crisp, print-ready PDF, a 300 DPI PNG or an SVG.
How to use the Graph Paper Generator
- Pick a grid type: square, dot, isometric, isometric dots or hexagon.
- Set the spacing in mm or inches, or click a preset.
- Choose the paper, orientation and margins, and optionally a title.
- Style it with a line color, line weight and major lines.
- Download PDF for printing, or PNG / SVG for digital notes and design apps.
Common graph paper sizes
| Name | Square size | Squares on A4 (10 mm margins) | Squares on Letter (10 mm margins) | Typical use |
|---|---|---|---|---|
| Fine metric | 2 mm | 95 × 138 | 97 × 129 | Precise plots, pixel art |
| Standard metric | 5 mm | 38 × 55 | 39 × 51 | Math and science notebooks |
| Centimeter | 10 mm | 19 × 27 | 19 × 25 | Primary school, area and counting |
| Quad ruled | ¼ in (6.35 mm) | 29 × 43 | 30 × 40 | US school and engineering pads |
| 5 per inch | ⅕ in (5.08 mm) | 37 × 54 | 38 × 51 | Engineering and drafting |
| Large | ½ in (12.7 mm) | 14 × 21 | 15 × 20 | Young children, big plots |
Formula: squares across = ⌊(paper width − 2 × margin) ÷ square size⌋, and the same for the height. Example: A4 is 210 mm wide, so with 10 mm margins and 5 mm squares you get ⌊190 ÷ 5⌋ = 38 squares across and ⌊277 ÷ 5⌋ = 55 down. The grid is centered so any leftover space is shared equally between both sides.
Isometric and hexagon geometry
Isometric paper is built from equilateral triangles. With a side length s, the vertical lines are s × √3 ÷ 2 ≈ 0.866 s apart, and the slanted lines run at 30° and 150° to the horizontal and are s apart measured vertically. A 5 mm isometric grid therefore has vertical lines every 4.33 mm.
Hexagon paper uses flat-topped regular hexagons with side s: each one is 2s wide and √3 × s ≈ 1.732 s tall, and columns are 1.5 s apart, with every second column shifted down by half a hexagon. Hexagons are popular for board-game maps, chemistry structures and quilting patterns.
Printing tips
- Print at 100% / Actual size. "Fit to page" shrinks the grid by a few percent.
- Light blue or gray lines are easy on the eyes and fade into the background when you draw in pencil or black ink; choose black only if you need the grid to photocopy well.
- Use Hairline or Fine weight with spacings under 5 mm, otherwise the lines crowd the paper.
- For bullet-journal pages, use a 5 mm dot grid with small dots.
Frequently asked questions
How do I print graph paper at the correct size?
Open the PDF and print it at "Actual size" or 100% scale. If your printer dialog is set to "Fit to page" or "Shrink oversized pages", the squares come out slightly smaller than the size you chose.
What is the most common graph paper size?
In the US, 4 squares per inch (1/4 inch, 6.35 mm) is the classic school and engineering paper; 5 per inch is also common. Elsewhere, 5 mm squares on A4 are standard, with 1 cm (10 mm) squares often used in primary schools.
What is isometric paper used for?
Isometric paper has lines (or dots) arranged in equilateral triangles, at 30° to the horizontal. It is used to sketch 3D objects, game maps, packaging, pixel-style art and technical drawings without perspective.
What are major lines?
Major lines are darker lines every few squares, for example every 5 or 10 squares. They make it easier to count and measure, and they are typical of engineering and quadrille pads.
Is the PDF a vector file?
Yes. The lines and dots are drawn as vectors, so the PDF stays sharp at any zoom level and prints crisply. The SVG download is also vector; the PNG is a 300 DPI image.
Is anything uploaded?
No. The paper is drawn and exported in your browser, so it works privately and even offline once the page has loaded.
