Printable 1 mm graph paper (millimetre paper)

The finest everyday grid

One-millimetre graph paper, often simply called millimetre paper, is the standard measuring grid of the metric world. Every square is 1 mm, every tenth line is bold, and so the page doubles as a ruler in two directions: count the bold squares for centimetres and the fine lines for millimetres. It is the paper of technical drawing classes, school physics practicals and sewing pattern drafting.

Because the minor lines are so close together, the generator draws them in a very light blue and thin weight. That keeps the grid from overpowering your drawing while still being easy to count against the bold centimetre lines.

Where millimetre paper shines

• Science and engineering graphs. Plotting experimental results to a precision of a millimetre makes reading values back off the graph far more accurate than on 5 mm squares.
• Scale drawings and floor plans. At 1:100, every millimetre on the page is 10 cm in reality, so a 4 m room is exactly 40 squares.
• Pattern drafting. Dressmakers and model makers draft small pieces at full size and take measurements straight from the grid.
• Electronics and lettering layouts. Plan component positions or letter spacing to the millimetre.

For less detailed work, 2 mm graph paper is easier on the eye, and 5 mm graph paper is the everyday school grid.

Printing tips

Precision paper is only useful if it prints at true size. Choose Scale 100% / Actual size in the print dialog, print one page and check that ten bold squares measure exactly 100 mm. If not, calibrate your printer once and every PDF will be corrected. For the classic look of European millimetre paper, try the orange variation above; for photocopying, the bold 5 mm lines make the grid easier to read on copies.
