Printable A4 graph paper (5 mm, 1 cm, 2 mm & more)

The international standard sheet

A4 is part of the ISO 216 series, the paper system used across Europe, Asia, Africa, Oceania and most of South America. Its sides have a ratio of 1 to √2, which means folding or cutting an A4 sheet in half gives two A5 sheets with exactly the same shape. That property is why A-series grids enlarge and reduce so neatly on a photocopier: an A4 diagram copied at 141% fills an A3 page with nothing cropped.

If you live outside the US and Canada, A4 is almost certainly the paper in your printer, so it is the safest default for school, office and home use.

Square sizes that fit A4 well

With 10 mm margins the printable area is 190 × 277 mm. Metric spacings divide that cleanly:

• 5 mm gives 38 × 55 squares, the standard squared-paper look. The default bolds every centimeter.
• 1 cm gives 19 × 27, good for primary math, bar charts and large diagrams. In landscape it becomes 27 × 19.
• 2 mm gives a 95 × 138 grid with bold centimeters, the usual choice for lab graphs.
• 1/4 inch fits 29 × 43, for families following US textbooks while living abroad.

Every option keeps the grid centered, so the margins come out equal even when the page does not divide into whole squares.

When to turn the page sideways

Landscape A4 suits time-series graphs, wide timelines, Gantt-style project plans and room layouts that are longer than they are deep. A 1 cm grid turned sideways gives 27 columns, enough for a month of daily readings with space for labels. Choose the landscape variation, or use the orientation switch in the generator for any spacing.

Printing A4 accurately

Check that your print dialog shows A4 as the paper size, not Letter, and set scaling to Actual size. Measure across 10 one-centimeter blocks: they should cover 100 mm. If you also need ruled pages to match, A4 lined paper is ready on the same sheet size. For the full family of sizes and where each is used, see our guide to paper sizes.
