Letterhead maker — headed paper that still leaves room for the letter
Build your organisation’s headed paper on A4, print a stack of it blank, or type a letter straight onto it. As you design the header this page measures it and tells you, in millimetres, how much of the page is left underneath — because a letterhead that eats the top third of the sheet is a letterhead nobody can write a one-page letter on.
- Header depth measured in millimetres
- Your logo and address stay in this browser
Blank sheets give you headed paper to write on, type on later, or feed back through the printer. The letter mode fills the same sheet in, so the header and the letter come out of one pass.
PNG, JPEG or WebP. A PNG with a transparent background sits cleanly on white paper. It is resized in your browser and kept with the draft on this device — it is never uploaded.
Split is the shallowest of the three: two columns make the header as tall as the taller side, not as tall as both added together.
Used for the organisation name and the rule. A dark colour still reads after a photocopy; a pale one turns to almost nothing in mono.
Your letterhead — logo included — is written to this browser’s own storage while you work, so it is waiting for you the next time a letter needs writing. Nothing leaves the machine; these pages are static files with no back end to receive anything. Use the button above to wipe it, or clear this site’s data.
Dear Sir or Madam,
Yours faithfully,
How it works
- 1
Put your name, address and logo in
Three layouts are offered. Split — name on the left, address on the right — is the shallowest of them, because two columns make the header as tall as the taller side rather than as tall as both added together. Centred is the deepest. The logo is sized in millimetres, not pixels, so what you set is what comes out of the printer.

Watch the millimetre readout
Under the layout controls sits a running measurement: how many millimetres the header takes, how many the footer strip takes, and how many are left for the letter — with the leftover also given as a rough number of typed lines. It is not an estimate. It is the measured height of the same header that gets printed, on A4 with the standard one-inch margins.

Push detail down into the footer strip
Registration numbers, branch addresses, a website and a tagline all read perfectly well in a small centred strip at the foot of the page, and every line you move down there is a line the letter gets back. The strip repeats on every sheet, and the page counts it against the space budget so the arithmetic stays honest.

Print it blank, or write on it
Blank mode prints up to twenty identical unnumbered sheets in one pass — stationery for the drawer, to be typed or written on later. Letter mode fills the same sheet in: reference, date, recipient block, subject, body, sign-off, enclosures and copies, with continuation sheets carrying a single thin identifying line instead of the whole header again.

Print or save as PDF
Each page is laid out as a real A4 sheet carrying its own margins, so the preview and the paper agree by construction rather than by luck. Choose “Save as PDF” in the print dialog and you get a vector file with selectable, searchable text.
Frequently asked questions
How deep should a letterhead header be?
Shallow enough that an ordinary letter still fits on one sheet, which is the only test that matters. A4 is 297 mm tall and the standard one-inch margins take about 40 mm of that, so a header and footer adding up to more than about 100 mm leaves you fighting for space on every letter you write. This page warns you when your header and footer cross that line, and until then it just shows you the number.
Can I print a stack of blank sheets to write on later?
Yes — that is what blank mode is for. Set a number up to twenty and each sheet comes out identical and unnumbered, because each one is a first sheet rather than page three of anything. It is the same header the letter mode uses, so a letter typed here later lines up with a sheet printed today.
Can I put pre-printed letterhead back through the printer?
Physically yes, and people do it, but you have to leave the header area empty in whatever you print second — otherwise your typed text lands on top of the printed logo. Blank mode exists precisely so you do not have to guess where that boundary is: print one sheet, hold it up to the light against a letter printed from letter mode, and you can see exactly where the body starts.
How big should the logo be?
The field takes a height in millimetres and 14 mm is a reasonable starting point — about half an inch, roughly two lines of text. Width follows the shape of your image. Setting it in millimetres rather than as a percentage means the printed size does not change when you switch between the on-screen preview and paper, and it means the page can subtract the logo from the space budget correctly before the image has even finished loading.
Will the accent colour survive a photocopy?
A dark one will; a pale one usually will not. Letterheads get photocopied, scanned and faxed far more than most documents, and a light grey rule that looks refined on screen can disappear entirely in mono. If your organisation only has a pale brand colour, the safer choice is to use it for the name and leave the rule dark.
What should go on the second sheet of a letter?
Not the whole letterhead again. Repeating a 35 mm header on page two spends the same space twice and tells the reader nothing they did not have. The convention this page follows is a single thin line carrying the organisation name and the subject, which is enough to identify a sheet that has come loose from the rest. You can switch it off entirely.
Why is the very edge of my printed page cut off?
Most home and office printers cannot print right to the edge of the paper — there is a narrow band around the sheet the mechanism simply cannot reach, and it varies by model. Nothing here is placed in that band, and the one-inch margins are far outside it, but it is worth knowing if you were planning a full-bleed colour band across the top. That is a job for a commercial print run, not a desktop printer.
Where does my logo go when I upload it?
Into your own browser and nowhere else. The file is read locally, resized on a canvas, and written to this browser’s own storage alongside the rest of your letterhead, so it is waiting for you next time — which is the whole point of having a letterhead at all. Nothing is transmitted: these pages are a folder of static files with no back end to receive anything. Wipe it with the clear button on the form, or by clearing this site’s data.
Why print instead of offering a PDF download?
Because your browser already makes better PDFs than a JavaScript library can. Choosing “Save as PDF” in the print dialog produces a vector document whose text can be selected, searched and copied. A PDF library would add roughly 40 KB to every visit and draw the letters as shapes instead — searchable by nothing, selectable by nobody. The cost of doing it this way is one extra dialog.
