Personal Letter Format: Parts, Examples and Envelope Rules

The standard personal letter format has six parts in this order: a heading with the date (plus your address if the reader needs it), a greeting such as "Dear Sam," the body, a closing such as "Love," or "Warmly," your signature, and an optional P.S. A comma follows both the greeting and the closing. You can indent each paragraph in the traditional style or keep everything flush left in block style, as long as you stay consistent.

This guide walks through each part with its formatting rules, shows how a personal letter differs from a business letter, and explains how to type or handwrite one. You'll also find greetings and closings matched to different relationships, USPS rules for addressing the envelope, five full sample letters, common mistakes and a printable checklist.

Key Takeaways

• A personal letter has six parts: heading or date, greeting, body, closing, signature and an optional P.S.
• Put a comma after the greeting ("Dear Maya,") and after the closing ("Love,"). Business letters use a colon after the greeting instead.
• Your street address is optional in a personal letter, but the date is almost always included.
• Capitalize only the first word of a closing, so write "With love," not "With Love,".
• On the envelope, USPS asks for the return address in the top left, the delivery address in the bottom center and the stamp in the top right.

The Six Parts of a Personal Letter Format

Every part has a job. Here they are in the order they appear on the page.

1. Heading or Date

The heading sits at the top. In a casual letter it is often just the date, written out in full (November 3, 2026). If the reader may want to write back and doesn't have your address, put your street address on the lines above the date. The Appalachian State University guide to friendly letters describes the heading as your address, line by line, with the date as the last line. In the indented style, the heading starts just right of the page's center. In block style, it sits at the left margin.

2. Greeting

The greeting (also called the salutation) names the person you are writing to. "Dear" plus a first name is the classic choice, but "Hi Jordan," or "Hello Grandma," works for close friends and family. Capitalize the first word and the name, and end the line with a comma. Leave one blank line after it.

3. Body

The body is the message itself. Open with a warm line that connects to the reader, then move into your news, thanks or reason for writing. Keep paragraphs short, three to five sentences each, and give each one a single topic. End the body with a forward-looking line, such as a question, a plan to meet or a wish for the reader.

4. Closing

The closing (or complimentary close) is a short phrase on its own line, such as "Love," "Warmly," or "Your friend," followed by a comma. Only the first word is capitalized. In the indented style, line the closing up with the heading. In block style, keep it at the left margin.

5. Signature

Sign your name directly under the closing. In a personal letter, your first name or a nickname is fine. If you typed the letter, leave a little space for a handwritten signature, because a signature in your own hand makes a typed letter feel personal.

6. Postscript (P.S.)

A P.S. (short for postscript) is an optional afterthought placed below the signature. Use it for a quick extra detail, like "P.S. Bring the photos when you visit!" Keep it to one or two sentences. If you need a second one, label it P.P.S.

Indented vs Block Style

There are two accepted layouts for the proper format for a personal letter. Pick one and use it all the way through.

Block style is the easier choice when you type, because you never need to tab across the page. It is also the layout Purdue OWL describes for business letters, where the whole letter is left justified with a blank line between paragraphs.

Personal Letter vs Business Letter

A personal letter goes to someone you know and follows looser rules. A business letter goes to an organization or someone in a professional role. The differences show up in nearly every part.

Purdue OWL's business letter guide calls for a colon after a business salutation, never a comma, and four blank lines between the closing and the typed name to leave room for a signature. A personal letter skips the typed name and just uses a handwritten one. If you are writing to an instructor rather than a friend, use the more formal pattern in our guide on how to email your professor.

How to Write a Personal Letter Step by Step

Here is how to write a personal letter from blank page to sealed envelope.

1. Decide on the purpose. Thanks, news, congratulations, sympathy or an apology. One clear purpose keeps the letter focused.
2. Write the date at the top, and add your address above it if the reader needs it.
3. Choose a greeting that matches your relationship, and end it with a comma.
4. Open warmly. Ask how the person is, mention a shared memory or say why you're writing.
5. Write the main message in one to three short paragraphs. Use specific details, such as names, places and what something meant to you.
6. Wrap up with a line about the future, like a visit, a call or a good wish.
7. Add the closing, capitalizing only its first word and ending with a comma.
8. Sign your name, then add a P.S. if you have a quick extra thought.
9. Proofread for names, dates and spelling before you seal it.

If you write by hand, use blue or black ink and leave even margins. Practicing neat joined handwriting helps, and our guide to how to write in cursive has a short practice plan.

How to Type a Personal Letter

If you'd rather type, the steps are simple in Word or Google Docs.

1. Set 1-inch margins on all sides and choose a readable font such as 12-point Times New Roman, Georgia or Calibri.
2. Use single spacing within paragraphs and a blank line between paragraphs (block style).
3. Type the date at the top left. Add your address above it only if needed.
4. Type the greeting, body and closing, all flush left.
5. Leave three or four blank lines under the closing, print the letter and sign in that space.

Keep a typed personal letter to one page when you can. A short, sincere letter reads better than a long one that wanders.

Greetings and Personal Letter Closings by Relationship

The right greeting and closing depend on how close you are to the reader. Use this table as a starting point.

When you're unsure, "Dear [Name]," and "Warmly," fit almost any personal letter. For thank-you notes to school staff, see our thank-you notes for teachers guide.

How to Address the Envelope

The USPS guide to sending a letter sets out three placements:

• Return address (top left): your name, street address, and city, state and ZIP+4 Code on separate lines.
• Delivery address (bottom center): the recipient's name, street address, and city, state and ZIP+4 Code on separate lines.
• Stamp (top right): one First-Class Mail Forever stamp covers a standard letter up to 1 ounce.

USPS also asks you to print neatly in capital letters with a pen or permanent marker, skip commas and periods, and include the ZIP+4 Code when possible. Its Postal Explorer addressing page adds that both addresses go on the same side, parallel to the longest edge, and that you should use a PO box or a street address, not both. For apartments, USPS Publication 28 prefers the unit number at the end of the street line. A finished delivery address looks like this:

JORDAN LEE

482 MAPLE AVE APT 3B

COLUMBUS OH 43215-1234

To qualify for the standard letter price, the envelope must be rectangular and no larger than 11-1/2 by 6-1/8 inches. Square envelopes, popular for greeting cards, cost more to mail.

Thank-You Letter Sample

November 3, 2026

Dear Aunt Rosa,

Thank you so much for the graphing calculator you sent for my birthday. I had been borrowing my friend's all semester, so having my own made a real difference on my first calculus quiz.

It meant a lot that you remembered I was starting precalculus this year. I promise to send you a photo of my next test if it goes well.

I hope the garden survived the early frost. Mom says we might drive up over winter break, and I can't wait to see you.

With love,

Elena

Friend Catch-Up Letter Sample

November 3, 2026

Hey Marcus,

It's been way too long since we actually talked instead of trading memes. How is life in Denver? Did you end up joining the climbing club you kept mentioning?

Things here are busy in a good way. I switched my major to environmental science, and I'm spending Saturdays volunteering at the county park. Last week we counted more than forty bird species in one morning, which still surprises me.

Let's set up a call soon. I'm free most Sunday evenings.

Your friend,

Theo

P.S. I still have your blue hoodie. It's yours whenever you visit.

Congratulations Letter Sample

November 3, 2026

Dear Hannah,

Congratulations on getting into nursing school! I remember you studying anatomy flashcards at every lunch break junior year, so I know how hard you worked for this.

You've always been the person everyone calls when something goes wrong, and you're going to be a wonderful nurse. Your future patients are lucky.

Let's celebrate when you're home in December. Dinner is on me.

So proud of you,

Jasmine

Condolence Letter Sample

November 3, 2026

Dear Daniel,

I was so sorry to hear about your grandfather's passing. I only met him a few times, but I still remember him teaching us to cast a fishing line at the lake and laughing every time mine landed in the reeds.

I know how close the two of you were. Please don't feel you need to reply to this letter. If you want company, a meal or someone to walk the dog, I'm only a text away.

With deepest sympathy,

Chris

A condolence letter works best when it is short and specific. Share one real memory, offer one concrete form of help and avoid explaining the loss or comparing it to your own.

Apology Letter Sample

November 3, 2026

Dear Mia,

I'm sorry I missed your recital on Friday. I told you I'd be there, and then I let a group project run late without even texting you. That wasn't fair to you, and I understand why you were hurt.

From now on, I'll put your events in my calendar the day you tell me about them. I would love to hear you play the piece sometime this week if you're willing.

Your friend always,

Ava

A good apology names exactly what you did, avoids excuses, and says what you'll do differently. Notice that the structure stays the same across all five letters even though the tone changes.

Common Mistakes to Avoid

• Using a colon after the greeting. "Dear Sam:" belongs in business letters. Personal letters take a comma.
• Capitalizing every word of the closing. Write "Best wishes," not "Best Wishes,".
• Forgetting the date. Letters often become keepsakes, and the date matters later.
• Mixing layouts. Indenting some paragraphs but not others looks careless.
• Burying the purpose. Say why you're writing in the first or second paragraph.
• Writing vaguely. "Thanks for the gift" says less than naming the gift and how you'll use it.
• Adding punctuation on the envelope. USPS asks for no commas or periods in the address block.

Frequently Asked Questions

How Do You Write a Personal Letter?

Start with the date, then a greeting such as "Dear Sam," on its own line. Write a warm opening, your main message in a few short paragraphs, and a closing thought. Finish with a closing like "Love," and your signature, plus an optional P.S.

What Is the Correct Personal Letter Format?

The correct personal letter format runs heading or date, greeting, body, closing, signature and P.S. Use a comma after the greeting and the closing. Choose indented or block style and use it throughout the letter.

Do You Need an Address on a Personal Letter?

Not on the letter itself, unless the reader may need your address to write back. In that case, put your street address on the lines above the date. The envelope always needs both the return address and the delivery address.

Do You Use a Comma or a Colon After "Dear" in a Personal Letter?

Use a comma, as in "Dear Grandma,". A colon after the greeting is the convention for business letters. The closing also ends with a comma in both kinds of letters.

What Are Good Personal Letter Closings?

Common choices are "Love," "With love," "Warmly," "Your friend," "Take care," and "Best wishes,". Match the closing to the relationship, so save "All my love," for family or a partner. For sympathy letters, "With deepest sympathy," is a respectful option.

Where Does the P.S. Go in a Letter?

The P.S. goes below your signature, after a blank line. Keep it to a sentence or two of extra news or a friendly reminder. Don't use it for anything important that belongs in the body.

Is a Typed Personal Letter Acceptable?

Yes. A typed letter is easier to read, especially if it runs long. Print it, then sign your name by hand above or in place of a typed name so it still feels personal.

Formatting and addressing rules come from USPS's letter-mailing guide, Postal Explorer and Publication 28, Purdue OWL's business letter guide and Appalachian State University's friendly letter guide, as of Nov. 2026.
