The fastest way to write a letter on your computer

Open Microsoft Word, Google Docs, or any word processor already on your machine. Type your letter directly into a blank document. Format it with your address at the top, the date, the recipient's address, a greeting, your message, a closing, and your name. Save the file with a clear name like "Letter to Landlord" so you can find it later. Print it, sign it by hand if needed, and you are done.

You do not need special software or templates. A word processor handles all the formatting — spacing, margins, fonts — automatically. The letter sits on your computer until you print it, email it, or save it for your records.

Key Takeaways

  • Microsoft Word and Google Docs are the most common tools; both are free or come with Windows and Mac computers.
  • A standard letter has your address and date at the top, the recipient's address below that, then a greeting, body, closing, and signature.
  • Save your letter with a descriptive filename so you can find it again if you need to send it to someone else or keep a copy.
  • You can print the letter and sign it by hand, or type your name if you are sending it by email.

Opening Microsoft Word or Google Docs

On a Windows computer, click the Start button and type "Word" or search for "Microsoft Word" in the search box. Click the process when it appears. If you do not have Word, open your web browser, go to Google Docs (docs.google.com), and sign in with a Gmail account or create one for free.

On a Mac, open Spotlight by pressing Command and Space, type "Word", and press Enter. Or open your web browser and go to Google Docs the same way. Both programs give you a blank page ready for typing. Google Docs saves automatically to your account; Word asks you to save when you close the document.

Setting up the letter format

Start by typing your own address at the top left of the page. Press Enter twice, then type today's date. Press Enter twice again, then type the recipient's address — the person or company you are writing to. This goes on the left side of the page, just like your address.

Press Enter twice, then type a greeting. "Dear [Name]:" is standard. If you do not know the person's name, "To Whom It May Concern:" or "Dear Sir or Madam:" works. Press Enter twice and begin your message. The word processor handles line spacing and margins for you; you do not need to adjust anything.

Writing the body of your letter

Type your message in clear, short paragraphs. Each paragraph should cover one idea. Press Enter once between paragraphs. Keep sentences straightforward and direct — say what you need to say without extra words.

If you are writing a formal letter (to a landlord, employer, or government office), stay professional. If you are writing to a friend or family member, you can be more casual. Either way, spell-check catches most mistakes. In Word, red squiggly lines appear under misspelled words; in Google Docs, a small red dot appears in the toolbar when errors are found.

Closing and signing your letter

At the end of your message, press Enter twice and type a closing. "Sincerely," is the standard for formal letters. "Best regards," "Thank you," or "Yours truly," also work. Press Enter once and type your full name. If you are printing the letter, leave space between the closing and your name to sign by hand.

If you are sending the letter by email, you can type your name without leaving space. Some people add their phone number or email address below their name so the recipient can reach them. This is optional but helpful if they do not already have your contact information.

Saving and printing your letter

In Word, click File in the top left, then click Save. Choose where to save the file (your Documents folder is standard), give it a clear name like "Letter to Insurance Company," and click Save. The file stays on your computer with that name.

In Google Docs, the document saves automatically. Click the filename at the top to rename it to something you will recognize later. To print, click File and select Print. Choose your printer, the number of copies, and click Print. The letter comes out on paper ready to sign and mail, or to keep in your files.

Sending your letter by email instead of printing

If the recipient has an email address, you can send the letter directly without printing. In Word, click File, then Share, then Email. Choose whether to send the document as an attachment or as a link. In Google Docs, click Share in the top right, enter the recipient's email address, and choose whether they can view or edit the document.

Type a short message in the email itself — something like "Please see the attached letter" — so the recipient knows what they are opening. The letter appears as a file they can open, read, print, or save on their own computer.

Frequently Asked Questions

Do I need to buy Microsoft Word to write a letter?

No. Google Docs is free and works in any web browser. LibreOffice and OpenOffice are also free alternatives. Many computers come with Word already installed, so check your applications first before buying anything.

What font should I use for a formal letter?

Times New Roman, Arial, or Calibri are standard. Use size 11 or 12 point. Avoid decorative fonts like Comic Sans or script fonts for formal letters — they look unprofessional. The word processor sets a default font; you can change it by highlighting all text (Ctrl+A on Windows, Command+A on Mac) and choosing a new font from the toolbar.

Can I add a signature image to my letter instead of signing by hand?

Yes. In Word, go to Insert, then Signature Line, and follow the prompts. In Google Docs, go to Insert, then Drawing, and draw or type your signature. Save it and insert it into your letter. This works for emails but looks less formal than a handwritten signature on a printed letter.

How do I fix spacing if my letter looks too crowded or too spread out?

Highlight the text you want to adjust (or press Ctrl+A to select all). In Word, go to Format and click Paragraph. In Google Docs, go to Format and click Line Spacing. Choose single spacing for a tighter look or 1.5 spacing for more room. Adjust until the letter looks balanced on the page.

What if I want to use a template instead of starting from scratch?

Word has built-in templates. Click File, then New, and search for "letter" to see options. Google Docs has templates too — click the template gallery icon when you open Google Docs. Pick one, and it fills in the format for you. You just replace the sample text with your own information.
