Graph / Grid Paper PDF - Free Online Browser Tool

Generate printable math graph paper at a grid pitch you choose, with heavier lines every five squares.

Graph paper for maths, drafting or plotting needs a fixed square grid, and the standard is 5mm squares. This tool generates properly proportioned grid sheets at that pitch, with an adjustable minor grid and heavier major lines.

How to Use the Graph / Grid Paper PDF Tool

Four steps, and the whole thing runs locally on your own device.

  1. Choose the page size

    A4 or Letter, matching your paper.

  2. Set the grid pitch

    5mm squares are the standard for school and engineering work. Other pitches suit larger-scale plotting.

  3. Set the margin and major line interval

    The heavier major lines appear every N minor squares, which helps with counting and with reading coordinates.

  4. Generate and print

    Download the grid sheets. Printing at 100% is essential or the pitch will be wrong.

Frequently Asked Questions

Why must I print at 100%?

Because "Fit to page" rescales the sheet, and a 5mm square printed at 94% is 4.7mm. On grid paper the pitch is the measurement itself, so scaling makes it wrong.

Is 5mm the standard?

For school mathematics and most engineering work, yes. Very large drawings often use 10mm or 20mm so the squares stay countable.

Why are some lines heavier?

Major lines appear at a fixed interval of minor squares, giving a coordinate reference so you can count positions quickly instead of estimating.

Will faint grid lines survive printing?

Light grey lines print reliably on both inkjet and laser. Avoid extremely pale lines, which toner printers can drop entirely.

Can I use it for drafting or plotting data?

Yes, and the major lines make axes and coordinates far easier to read off than a plain unweighted grid would.
