Make an A4 letterhead in Word
For correspondence outside North America — convert your PDF to a Word file sized to A4, with the artwork in the header and footer.
Most of the world writes letters on A4 — 210 by 297 millimetres — not the 8.5-by-11-inch US Letter size. If your correspondence goes to the UK, Europe, Australia, or most of Asia, your Word letterhead needs to be A4, or it will print with the wrong margins and the artwork in the wrong place.
Letterhead Lab converts your designed PDF into a Word document set to true A4 dimensions. The letterhead artwork is cropped from your PDF and placed into the Word header and footer; the page size, margins, and body start position are all set for A4 so the file prints correctly on the first try.
You don’t need to resize anything in Word afterwards. The downloaded file is already A4 — open it, type your letter, and print or send a PDF that lines up exactly the way your designer intended.
A4 and US Letter from one PDF
The A4 output is part of Letterhead Lab’s Multi-page bundle ($79), which delivers both A4 and US Letter versions of your letterhead. Convert the PDF once and you have both page sizes — useful for any office that sends mail on both sides of the Atlantic — plus a .dotx template and continuation-header support for long letters.
Your source PDF can be any size. Letterhead Lab fits the artwork to the A4 page during conversion, so a US-Letter-proportioned design still lands cleanly. The live preview shows exactly how it falls before you commit.
As with everything here, the file is processed entirely in your browser and never uploaded. Preview the A4 layout free, then pay to download the final document.
Frequently asked questions
- What size is an A4 letterhead?
- A4 is 210 by 297 millimetres (about 8.27 by 11.69 inches) — the standard letter size across the UK, Europe, Australia, and most of the world outside North America.
- Can I get A4 and US Letter from the same PDF?
- Yes. The Multi-page bundle includes both A4 and US Letter versions of your converted letterhead, so one upload covers correspondence in either standard.
- Is the A4 version in the $39 price?
- No. The single $39 option produces a US Letter .docx. The A4 version is part of the $79 Multi-page bundle, which also includes a .dotx template and continuation headers.
- My PDF was designed at US Letter size — can it still become A4?
- Yes. Letterhead Lab fits your artwork onto the A4 page during conversion. The live preview shows exactly how it lands so there are no surprises.
- Will the A4 file print correctly?
- Yes. The downloaded Word file is set to true A4 dimensions with margins already configured, so it prints without resizing or shifting.
