Graph Paper Generator

Graph Paper Generator draws exact millimetre grids on real paper sizes, ready to print. Pick a spacing — 4, 5, 8 or 10 mm, or your own custom value — choose gray, blue or black lines, and the page is drawn as a true vector PDF right in your browser: every line stays razor sharp at any printer resolution, and the spacing on paper matches the spacing you asked for, provided you print at 100% scale.

Nothing to upload — set your options and the preview updates live. Downloads are generated on your device.

Print the PDF at 100% scale so sizes and spacings stay exact.

How to use Graph Paper Generator

  1. Choose the paper size, grid spacing and line colour.
  2. Check the live preview — it redraws as you change any option.
  3. Download the PDF for printing, or the PNG if you want an image of the page.
  4. Print at 100% scale (no 'fit to page') so the spacing stays exact.

Supported behavior

  • Grids are drawn in millimetres on A4, A5, Letter and Legal pages, in portrait or landscape.
  • The optional heavier line every 5 cells makes counting squares across the page much easier.
  • The PDF is true vector output — lines are drawn, not rasterised, so they print crisply at any DPI.

Best for

  • Maths and engineering homework that needs exact grids.
  • Sketching floor plans, charts and pixel-art drafts on paper.
  • Teachers printing class sets of grid paper on demand.

Limits

  • Exact spacing depends on your printer: print at 100% scale, never 'fit to page', or the millimetres will drift.
  • One page per download — print as many copies as you need from the same PDF.
  • Custom spacing is limited to 2–20 mm so the grid stays printable.

Privacy notes

  • Nothing is uploaded — this tool takes no file input at all. The page is generated locally in your browser from the options you set.
  • The options you pick are not sent anywhere; the preview and both downloads are generated on your device.

Graph Paper Generator FAQ

Why does my printed grid not measure exactly 5 mm?

Almost always the printer dialog: 'Fit to page' or a scaling percentage rescales the PDF. Set scaling to 100% (or 'Actual size') and the grid prints at the exact spacing.

What is the difference between the PDF and the PNG?

The PDF draws every line as a vector, so it stays sharp at any printer resolution. The PNG is the same page rendered as an image at 150 DPI — handy for slides or documents, slightly softer in print.

Can I get a heavier line more or less often?

The accent line repeats every 5 cells, the convention on most printed graph paper. You can switch it off for a uniform grid.

Which spacing should I choose?

5 mm is the everyday default for school and office work. 4 mm suits dense plotting, 8–10 mm suits younger students and large handwriting or sketching.
