How to use it
The grid uses whole squares only and is centred on the page. Add a bolder line every 5 or 10 squares for maths, charts and counting.
Print quality: the lines are true vector lines in the PDF, so they stay sharp on any printer at any zoom, and the file is tiny. Print at 100% (“Actual size”) so measurements stay exact to the millimetre. The file is created on your device.
Worked example
5 mm squares on A4 with a bold line every 10: about 38 × 54 squares, ideal for maths and drawing.
