Printable graph paper and grid paper, exact to the millimeter

Set the spacing, print at 100%, and measure: the squares come out true. The grid is drawn as vector geometry in your browser and sized in real millimeters, with no watermarks or sign-ups, and nothing is 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, where every coordinate is a real millimeter. The spacing can be anything from 1 mm to 50 mm, entered in millimeters or inches. When you change it, 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 millimeters and inches, and the exact column-by-row count, which is 38×50 on US Letter at the defaults.

When you print, leave the dialog at 100% or "Actual size"; check that setting once and it stays checked. "Fit to page" rescales the whole sheet, and a 5 mm grid then 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, which clears the mechanical dead zone of essentially every consumer printer, so nothing needs rescaling. At 100% the millimeters on paper match the millimeters on the readout; the methodology page shows how to verify that with a ruler.

Line weights below about 0.2 mm can print unevenly on consumer printers, which is why the default is 0.3 mm. Borderless edge-to-edge grids depend on printer hardware this page can't control, so the margin control stops at 5 mm.

Frequently asked questions

Will the squares really measure 5 mm when printed?
Yes, as long as the print dialog's scale is 100% (sometimes labeled "Actual size"). "Fit to page" shrinks the sheet to clear the printer's margins. The grid is generated in true millimeter units and kept inside a safe margin so nothing gets clipped, and a ruler on the first printout confirms the size.
What grid spacing should I use: 5 mm, 1 cm, or 1/4 inch?
Use 5 mm for math homework, sketching and general use; it is the standard metric grid and the default here. US quad-ruled paper is 1/4 inch: switch the unit selector to inches and enter 0.25. Engineering and fine technical work often use 2 mm, and knitting and cross-stitch charts usually want larger cells such as 10 mm. For 1 cm squares, leave the unit on mm and type 10; for 1/2 inch squares, enter 0.5 with the unit on inches.
How do I get a PDF instead of a printout?
Press Print, then choose "Save as PDF" as the destination in the dialog. Your browser makes the PDF itself, on your device, and this site does not create, store, or watermark a file on any server.
Why are the lines light gray by default?
Graph paper sits behind your work, and light gray stays in the background under pencil and ink. It also uses far less toner over hundreds of sheets. Blue, green, and red are in the Line color menu, and a heavier line weight darkens the grid 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 exists only on your device. There is no account, no watermark and no stored setting: close the tab and the sheet is gone.
