RandoziPrintable Graph Paper in Millimetres
A grid drawn in real millimetres, ready to print on A4 or US Letter. A 100 mm scale bar at the bottom lets you check with a ruler that the sheet came out at the right size.
Squares
38 × 53
Printable area 190 × 277 mm
The preview on screen is reduced to fit: measure the printed sheet, not the screen. Choose “Actual size” (100%) in the print dialog, then measure the 100 mm bar with a ruler.
How it works
- Choose the paper, the orientation, the size of one square and the margin.
- Pick how often a heavier line is drawn (every 5 or 10 squares), or none.
- Press Print and choose “Actual size” (100%) in the print dialog, not “Fit to page”.
- Measure the 100 mm bar with a ruler: if it is not 100 mm, adjust the print scale.
What people use it for

Craft and pattern making
Trace a template at real size on paper you printed yourself.
Questions
- Will it really be to scale?
- The sheet is drawn in millimetres, so it prints at scale when the print dialog is set to “Actual size” or 100%. Browsers and printers can still rescale a page or leave a non-printable border, so measure the 100 mm bar once with a ruler. The tool cannot check your printer.
- Why do the lines start at the margin?
- The grid starts at the corner of the printable area and runs in whole squares. The leftover part, less than one square, stays blank on the right and at the bottom. Most printers cannot print in the last 3 to 5 mm of the paper, so keep a margin of at least 5 mm.
- What does the scale bar take?
- A band of 12 mm at the bottom of the printable area, with a 100 mm bar and ticks every 10 mm. Turn it off to use the full height.
- Are there limits?
- The square size is 1, 2, 5 or 10 mm. The sheet is drawn as one vector image: the preview on screen is reduced to fit, the printout is not.
