Free Letterhead Generator

A letterhead is the branded heading — usually a logo, company name, and contact details — printed at the top of official correspondence. It exists for one reason: professionalism. A letter on plain paper reads as informal, even careless; the same letter on a clean letterhead reads as something an organization stands behind. That matters most for correspondence with legal or financial weight — contracts, invoices, formal notices, offer letters — where the reader needs a quick, confident signal that the document is legitimate. It also reinforces brand consistency: every letter, quote, or notice that goes out carries the same logo, colors, and contact details, so recipients recognize your organization at a glance regardless of who on your team sent it.

At minimum: your logo, full company name, and a way to reach you — phone, email, or both. Most letterheads also include a physical address (required for a lot of formal and legal correspondence), a website, and — for regulated industries or government submissions — a company registration or tax number. Keep the list tight: a letterhead crowded with every possible detail starts competing with the letter itself. Logo, name, and the two or three contact methods someone is actually likely to use is usually enough.

A4 (210 × 297 mm) is the standard almost everywhere outside North America — Europe, Africa, most of Asia, and Latin America all print on A4 by default. US Letter (215.9 × 279.4 mm) is the standard across the United States and Canada — slightly wider and slightly shorter than A4. US Legal (215.9 × 355.6 mm) is longer again, mostly reserved for contracts and legal filings that need the extra length. Pick based on where your recipient — or your printer — is; sending an A4 letterhead to a US Letter printer (or vice versa) usually just prints fine with slightly different margins, but matching the regional standard looks more deliberate.

Download Word (.docx) when you’re about to write an actual letter — the logo and details sit in the document’s Header, so the body stays free for typing, and anyone on your team can reuse the same file for the next letter. Download PDF when you need something print-ready and final — it looks identical on every device, doesn’t shift when opened in a different app, and reads as more finished for a one-off document you’re not going to edit further. Download the image (PNG) when you need to drop the letterhead into a tool that doesn’t accept Word or PDF at all — pasting a header into Google Docs, an email signature, or a slide deck. The header-only transparent version is built specifically for that last case.

• Use a PNG logo with a transparent background — it drops cleanly onto any template, including ones with a colored header band, instead of showing an ugly white box.
• Limit yourself to two brand colors — a primary and an accent. More than that starts to look like a ransom note instead of a letterhead.
• Leave enough body space. A header (and footer, if you use one) that eats a third of the page leaves too little room for an actual letter — keep the branded area lean.
• Keep contact details to what someone would actually use — phone and email cover most cases; add a physical address and registration number only where the document type calls for it.

Download the .docx, open it in Microsoft Word (or Google Docs, or LibreOffice), and click anywhere in the blank body area below the header. Type your letter exactly as you would in any Word document — the logo, company name, and contact details stay anchored in the header and repeat automatically if the letter runs to a second page. If you turned on “Include sample letter body text” before downloading, you’ll see placeholder date, recipient, and paragraph lines already in place — delete them and type over them, or use them as a guide for where each part of the letter goes.
