Printable Graph Paper Generator

Squared paper is one of those things that takes twenty minutes to fake in a word processor and still comes out with the margins wrong. This draws it properly: a line every five millimetres, or two, or ten, on the page size you actually print on, with the spacing measured off the finished drawing rather than merely intended.

Kind of paper

Page size

Spacing in millimetres

Between 2 and 40.

Margin in millimetres

Blank edge on all four sides, up to 40.

Heavier line every

In squares. Set to 0 for lines of one weight.

Landscape

210 by 297mm, 5mm spacing, 10mm margin. Print at 100% — not “fit to page” — and the squares measure what they say.

✓ Nothing is drawn into the margin — 95 lines and 0 dots all sit inside the 10mm margin
✓ Every gap is the spacing you asked for — 93 gaps measured, every one 5mm to within a hundredth
✓ As many rows and columns as the page has room for — 38 columns and 55 rows fit in 190 by 277mm
✓ The sheet prints at its stated size — 210 by 297mm, with the drawing measured in millimetres

What this generator does

Works out how many whole squares fit inside your margins, centres the grid in what is left, and draws it as an SVG measured in millimetres so it prints at true size.

How to use this tool

Choose the kind of paper — squares, dots, isometric, hexagons, ruled or Cornell.
Pick the page size and whether it is portrait or landscape.
Set the spacing in millimetres and how wide a margin to leave.
Download the SVG and print it at 100%, not scaled to fit.

Understanding the controls

Kind of paper: Squares, dots at the corners, isometric triangles at thirty degrees, flat-topped hexagons, plain rules, or Cornell note paper with its cue column and summary box.
Page size: A4, A3, A5, US Letter or US Legal, portrait or landscape. The drawing is sized in millimetres so it matches the paper in the tray.
Spacing in millimetres: The distance between lines, dots or hexagon centres, from two millimetres up to forty. Five is the usual school squared paper.
Margin in millimetres: How much blank edge to leave. Ten millimetres or so keeps the grid clear of what most printers refuse to print near the edge.
Heavier line every: Draws every nth line thicker, which is what makes centimetre squares readable on five-millimetre paper. Zero gives every line the same weight.
Landscape: Turns the page on its side, swapping the width and height before anything is drawn.

Common use cases

Maths homework that needs squared paper when the pad has run out
Isometric paper for technical drawing or design coursework
Hex paper for mapping a tabletop campaign
Dot grid pages for bullet journalling at a spacing you choose
Cornell note pages for revision, at the proportions the method specifies

How this generator works

The number of whole steps that fit between the margins is worked out first, and the grid is centred in the remainder so the outer edge lands on a line rather than mid-square. The check then measures the drawing rather than trusting the loop that made it: the gap between every pair of neighbouring rules must equal the spacing to within a hundredth of a millimetre, nothing may cross into the margin, and the row and column counts must match what the page size and spacing imply. For hexagons, where there are six angles rather than two, every side is measured instead.

Randomness and fairness

Nothing is random. The same settings always draw exactly the same sheet.

For how randomness is produced across the whole site, see how Generate Random works.

Limitations and good to know

Printing at anything other than 100% changes the spacing; most print dialogues default to scaling to fit.
The output is an SVG rather than a PDF, which every browser and word processor will place and print.
Isometric paper is drawn at thirty degrees, the usual convention; other angles are not offered.
Very fine spacings below two millimetres are not offered, because most printers cannot resolve them.
