Printable graph paper, exact to the millimeter

Set the spacing, print, and measure it — the squares are true. Generated in your browser as vector geometry, sized in real millimeters, with no watermarks, no sign-ups, and nothing uploaded. Print it on paper or save it as a PDF from the same dialog.

How this generator works

The sheet you see is an SVG drawn in physical units: every coordinate is a real millimeter, not a screen pixel. When you change the spacing, the page computes how many whole cells fit inside the printable area — the sheet minus your margin — and centers the grid so you never get sliced partial squares at the edges. The readout shows the resulting geometry: sheet size, true spacing in both units, and the exact column-by-row count.

Printing is where most graph-paper sites quietly fail, because "Fit to page" rescales their fixed PDFs and a 5 mm grid arrives as a 4.7 mm grid. This page sets the print size to match your chosen sheet exactly and keeps the pattern inside a 12.7 mm default margin — within the mechanical dead zone of essentially every consumer printer — so nothing needs rescaling. Leave the dialog at 100% or "Actual size" and the millimeters on paper match the millimeters on the readout; the methodology page shows how to verify with a ruler.

The honest limits: if your print dialog is set to fit, shrink, or scale, no generator can save the measurements — check that setting once and it stays checked. Line weights below about 0.2 mm may render inconsistently on consumer printers, which is why the default is 0.3 mm. And borderless edge-to-edge grids depend on printer hardware this page can't control, so the margin control stops at 5 mm rather than pretending zero works everywhere.

Frequently asked questions

Will the squares really measure 5 mm when printed?
Yes — on one condition: the print dialog's scale must be 100% (sometimes labeled "Actual size"), not "Fit to page", which silently shrinks the sheet to dodge printer margins. The grid is generated in true millimeter units, this page keeps it inside a safe margin so nothing gets clipped, and a ruler on the first printout will confirm it.
What grid spacing should I use?
5 mm is the standard metric grid and the default here — right for math homework, sketching, and general use. US quad-ruled paper is 1/4 inch (switch the unit selector and enter 0.25). Engineering and fine technical work often uses 2 mm; knitting and cross-stitch charts usually want larger cells like 10 mm.
How do I get a PDF instead of a printout?
Press Print, then choose "Save as PDF" as the destination in the dialog. That's by design: your browser generates the PDF itself, on your device — this site never creates, stores, or watermarks a file on any server.
Why are the lines light gray by default?
Because graph paper is a background instrument: light gray recedes behind pencil and ink instead of competing with your work, and it uses far less toner over hundreds of sheets. Blue, green, and red are one click away, and the line-weight control darkens things if your printer runs faint.
Is anything uploaded or stored?
No. The sheet is generated as vector geometry inside this page, printed through your browser's own dialog, and never exists anywhere but on your device. No account, no watermark, no stored settings — close the tab and it's gone.
