Printable paper

Eight rulings at whatever spacing you ask for, as a PDF carrying real millimetres, with a printed line to prove your printer did not shrink it.

Paper type

210 × 297 mm · 98 marks

Set the print dialogue to 100% or "actual size". Leave it on "fit to page" and the grid comes out shrunk, which defeats the point of squared paper.

Adds a 100 mm line in the bottom margin. Put a ruler on it: if it is not exactly 100 mm, your printer rescaled the sheet and the grid is not the size it says either.

The PDF carries the sheet geometry in millimetres, so it comes out exact as long as you do not rescale it when printing.

Printable paper has exactly one hard requirement, and almost every page offering it ignores the requirement completely. A 5 mm grid has to come out of the printer at 5 mm. If it arrives at 4.7 you cannot measure on it, your scale drawing is wrong by six per cent, and the graph you plotted is a picture rather than a record.

That is not a rare accident. It is the default. Print dialogues open on "fit to page" or "shrink oversized pages", and those settings quietly take a percent or three off every dimension to make room for a margin your printer cannot reach into. A web page sent to a printer has no say in the matter at all — whatever the browser decides, you get.

So this generator does not print a web page. It writes a PDF that carries the sheet geometry in millimetres, which is a thing a printer will honour, and then it prints a line of a stated length in the bottom margin so you can put a ruler on the result and know rather than hope. Eight rulings, any spacing you ask for, and nothing to install or sign up for.

Manual

How to use it

1
Pick the ruling

Square grid, dots, isometric, hexagonal, ruled, handwriting, music staff or polar. The spacing resets to something sensible for each, because 5 mm means a good square and an unwritable line.
2
Set the size and the spacing

A4 through A5, Letter, Legal and Tabloid, portrait or landscape. Type the spacing in millimetres or inches — **1/4 inch is 6.35 mm** and **1/5 inch is 5.08 mm**, which is what American graph paper usually means by four or five squares to the inch.
3
Set the margin to suit your binder

The rulings are generated inside the margin, so it stays genuinely clear. Fifteen millimetres is enough for a three-hole punch without a hole landing on a line.
4
Turn on a heavier line every few squares

On squared, ruled and polar paper. Nobody counts to twenty squares reliably; everybody counts to four heavy ones. None of the eleven pages that rank for this offer it.
5
Leave the check line on for the first sheet

It prints a 100 mm rule with ticks at both ends, in the bottom margin, and says so on the sheet.
6
Download the PDF and print it at 100%

In the print dialogue set the scale to **100%** or **Actual size** — not "Fit to page". Then measure the check line. If it reads 100 mm you are done, and every square on the sheet is the size it claims.

In depth

Things worth keeping in mind

Which ruling is for what

The eight here are not variations on a theme; each one exists because a particular job is painful on the others.

Square grid — plotting, scale drawings, cross-stitch charts, pixel art. 5 mm for general use, 1/4 inch if you are working to American conventions.
Dot grid — bullet journals and sketching. The dots position you without boxing in what you draw, and they disappear behind ink in a way lines do not.
Isometric — anything three-dimensional drawn by hand. Cubes, floor plans, mechanical sketches, and the entire look of certain video games.
Hexagonal — organic chemistry, tabletop maps, quilting. A hex grid has no diagonals, which is why board games measure distance on it more sensibly than on squares.
Ruled — writing. Set 7 mm for something near American college ruled, 8.7 mm for wide ruled.
Handwriting — three rules to a row with a dashed midline, for children learning letter heights. The row height is what a teacher means, not the line spacing.
Music staff — five lines to a stave with room to write between. The spacing is the gap between the staff lines, so 2 mm gives an 8 mm stave.
Polar — angles and radial data. Concentric circles at your spacing, with spokes every fifteen degrees.

The rulings by their proper names

If you are trying to match paper you already own, these are the numbers to reach for. Ruled paper is measured between the lines you write on; graph paper is measured between adjacent lines of the grid.

Wide ruled (also legal ruled) — 8.7 mm, the American default for school exercise books.
College ruled (medium ruled) — 7.1 mm, standard for older students and most refill pads.
Narrow ruled — 6.35 mm, exactly a quarter inch.
Séyès — French, 8 mm rows with 2 mm guides and 8 mm verticals. Not offered here as a preset; set 8 mm ruled to get close.
Quadrille — the general name for squared paper, usually 5 mm or 1/4 inch.
Engineering — typically 1/5 inch (5.08 mm) with heavier lines every fifth, printed on the reverse of the sheet.
Metric graph — 5 mm with a heavier line every ten, which is a 1 cm major grid, the European school standard.

History

Two hundred years of paper with lines on it

Printed coordinate paper is older than most people assume. A patent for it was granted in England in 1794 to a Dr Buxton, and by the middle of the nineteenth century squared paper was ordinary equipment for engineers and surveyors. What it was not, for a long time, was school equipment: it was a professional tool you bought from a drawing-office supplier.

That changed around 1900, largely through the American mathematician **E. H. Moore** at the University of Chicago, who argued hard for squared paper in secondary teaching. The argument won, and within a generation graph paper was something every schoolchild in the industrialised world had a pad of.

Ruled writing paper went its own way, and it went differently in different countries — which is why "lined paper" means three different things depending on where you ask. American paper is sold as **wide ruled** at 8.7 mm, **college ruled** at 7.1 mm and **narrow ruled** at 6.35 mm. French schools use **Séyès ruling**, patented by Jean-Alexandre Seyès in 1892: an 8 mm main line with three 2 mm guides between, and vertical lines every 8 mm, which is why French exercise books look like graph paper to everyone else.

The sheet itself was standardised much later than the lines on it. **DIN 476**, published in Germany in 1922 and largely the work of Walter Porstmann, defined the A series on one elegant constraint: the sides are in the ratio of the square root of two, so folding a sheet in half gives you the next size down with the same proportions, and A0 is exactly one square metre. US Letter has no equivalent documented logic — the origin usually repeated is folklore — and it was fixed as the American federal standard only in 1980.

How it works

Why a PDF and not a printed web page

A browser printing HTML has to decide how to map CSS pixels onto paper, and it does so through a chain you do not control: the page zoom, the print dialogue scale, the "fit to printable area" checkbox and the printer driver's own unprintable margin. Every link can scale, and by default at least one of them does. A CSS millimetre is a real millimetre in the specification and a suggestion in practice.

A PDF works the other way round. The file declares a **MediaBox** — the page rectangle, in points — and everything inside it is positioned in the same units. A point is exactly 1/72 of an inch, so 210 mm is 210 × 72 ÷ 25.4 = 595.28 points, and an A4 PDF says exactly that. Given that, a printer has a page it can place directly; the only thing that can still go wrong is you telling the dialogue to scale it, which is why the sheet asks you not to.

Everything on the sheet here is generated in millimetres and converted once, at the end, into points. The preview on screen is drawn from the same model, so what you are looking at and what comes out of the printer cannot quietly disagree about anything.

The check line closes the loop. Any tool can claim it prints at true size; this one prints a measured object next to the claim. If the line is 97 mm, your dialogue scaled the page by three per cent and so did every square on it — and you know that in five seconds instead of after ruining a drawing.

By hand

Ruling a sheet with nothing but a ruler

Worth doing once, because it teaches you what the machine is actually doing and it is how you get squared paper at three in the morning with no printer.

1

Ten or fifteen millimetres. Use the ruler, not your eye: a margin that drifts is what makes a hand-ruled sheet look hand-ruled.
2

Every 5 mm along both, working from the same corner each time so any error in the ruler cancels rather than accumulating.
3

Set the ruler on the two ticks and draw the whole line in one pass. Stopping halfway and restarting leaves a visible kink at the join.
4

The horizontals. If you have a set square, use it against the verticals you have already drawn rather than against the paper edge, which is rarely square.
5

Once more with the same pen. This is the step that turns a mesh you have to count into a grid you can read at a glance.

Diagnosis

If something is not working

Symptom:The check line does not measure what the sheet says

Likely cause:: The print dialogue scaled the page. "Fit to page", "Shrink oversized pages" and "Scale: Auto" all do this, and at least one of them is usually on by default.
What to do:: Reprint with the scale set to **100%** or **Actual size**. On macOS the setting is "Scale: 100%" in the print sheet; in Chrome it is under **More settings → Scale → Custom → 100**; in Acrobat it is "Page Sizing: Actual size".

Symptom:The grid is right but the margins are wider than I set

Likely cause:: Your printer has an unprintable border it physically cannot reach, usually three to five millimetres, and it adds that to whatever margin the file asks for.
What to do:: Nothing is wrong with the sheet — the rulings are still the size they claim, which is what matters. If you need the grid closer to the edge, reduce the margin here by roughly what your printer adds.

Symptom:The lines are so faint I can barely see them

Likely cause:: A light grey at 0.1 mm is close to what a laser printer can resolve, and an inkjet low on toner or ink will drop it altogether.
What to do:: Raise the line weight to 0.25 mm or pick a darker colour. Grey at 0.2 mm is a good compromise: visible enough to follow, pale enough not to compete with pencil.

Symptom:The PDF opens but the page is blank

Likely cause:: A very fine spacing with a very light weight can produce a sheet whose lines are below the resolution your viewer renders at, so it shows white until you zoom in.
What to do:: Zoom to 200% and look again before assuming it failed. If it is genuinely empty, raise the spacing above 2 mm and the weight above 0.1 mm.

Symptom:A hole punch lands on a line and the sheet looks wrong

Likely cause:: The margin is smaller than your punch reaches.
What to do:: Set the margin to 18–20 mm. A standard three-hole punch centres its holes about 12 mm from the edge, so anything from 18 mm up keeps them clear of the ruling.

Symptom:The preview is slow to move when I drag the spacing

Likely cause:: A 1 mm grid on A3 is around six hundred lines, and every one is a separate element the browser has to lay out.
What to do:: It is drawing, not stuck. The mark count is printed under the sheet; above about four thousand, expect the preview to lag while the PDF itself stays quick.

Trivia

Things worth knowing

A0 is one square metre, and that fixes every other A size

Pick a rectangle of area 1 m² whose sides are in the ratio √2 and you get 841 × 1189 mm. Halve it repeatedly and you get A1 through A10, each keeping the ratio. It is the only paper system where enlarging A4 to A3 needs no cropping.

American graph paper is counted per inch, not per millimetre

"Four squares to the inch" is 6.35 mm and "five to the inch" is 5.08 mm. Neither is a round metric number, which is why an American pad and a European one never quite line up over a light box.

Engineering paper prints its grid on the back

The pale green pads sold for engineering coursework are ruled on the reverse, so the grid shows faintly through and guides your writing without photocopying. Work reproduces as clean lines on white.

Isometric paper is not squared paper with diagonals

Its rows sit a triangle height apart — the spacing times √3÷2 — so the cells are equilateral and a cube drawn on it has three equal faces. Get that wrong and every drawing leans.

The default print setting is the enemy

"Fit to page" and "shrink oversized pages" exist because printers cannot reach the very edge of a sheet. They solve that by scaling the whole page down a few per cent, silently, which is fine for a letter and ruins graph paper.

Questions

Frequently asked questions

Is this printable paper free, and does anything leave my device?

It is free with no account, and nothing leaves your device. The sheet and the PDF are both generated in your browser; no file is uploaded and no server sees what you made.

Will it actually print at the size it says?

Yes, if the print dialogue is set to 100% or Actual size. The PDF carries the page geometry in real units, so the printer has an exact page to place. What can still spoil it is the dialogue scaling it for you, which most of them offer to do by default — so leave the check line on for the first sheet and measure it.

What is the check line for?

It is a rule of a stated length, with a tick at each end, printed in the bottom margin. Put a ruler across it. If it measures what the sheet says, every square is the size it claims; if it is short, your printer scaled the page and everything on it by the same fraction.

How do I get four or five squares to the inch?

Switch the spacing to inches and type 0.25 or 0.2. In millimetres those are 6.35 and 5.08 — not round metric numbers, which is exactly why American and European squared paper never quite match.

Can I get A4 graph paper with 1 cm squares and a lighter 1 mm grid inside?

Not as two different spacings at once. Set 5 mm with a heavier line every second, or 1 mm with a heavier line every ten, and you get the same readable effect from one grid — which is how European school pads are actually ruled.

Why is my printed margin bigger than the one I set?

Every printer has a border it cannot physically reach, usually three to five millimetres, and it sits outside whatever you ask for. The rulings inside are unaffected and still measure correctly, which is the part that matters.

What spacing should I use for handwriting practice?

The number here is the row height, which is what a teacher means. Around 12 mm suits a child starting to write, 8 to 10 mm suits somebody who has the letter shapes and is working on consistency. The dashed midline marks the x-height.

Can I print more than one page?

The PDF is one sheet, and your print dialogue will run off as many copies as you ask for — which is the same thing and keeps the file small. Set the copy count there rather than generating a hundred identical pages.

Does it do logarithmic or semi-log paper?

Not yet. Polar is here, but log and semi-log rulings need a different generator and would be guesswork to add without doing them properly. Everything offered is offered because it is right, rather than to lengthen the list.
