Format of an Informal Letter

While the format for informal letters offers more freedom of expression, they still follow a basic structure that helps maintain clarity and coherence. Here’s a standard format:

1. Sender’s Address

This appears at the top right corner of the letter. It includes the writer’s full address and sometimes the date.

Example:

Hiranandani Estate

Mumbai– 501502 

India 

31st May, 2026

Examples:

• Dear Mom,
• Hi Rahul,
• My dearest Riya,

Avoid overly formal greetings like “Respected Sir/Madam” in an informal letter.

3. Introduction

Begin with a warm opening. Ask about the recipient’s health or life, and state the reason for writing.

Example:

"I hope this letter finds you in great health and good spirits. It’s been a while since we last caught up, and I wanted to share some exciting news with you."

4. Body of the Letter

This is the main part, where you express your thoughts in detail. It can be one or multiple paragraphs.

Structure your thoughts clearly:

• First paragraph: Explain the reason for writing.
• Middle paragraphs: Share details, anecdotes, or emotions.
• Final paragraph: Conclude with hopes, well wishes, or an invitation to reply.

Sample Informal Letter-

Scenario: Write to a friend about your recent trip.

23, Sunrise Apartments 

Lake View Road 

Udaipur

India 

31st May, 2026 

Dear Shikha,

I hope you're doing great. It’s been a while since we last met, and I’ve been dying to tell you about my recent trip to Kashmir.

The mountains were absolutely breathtaking, covered in snow and kissed by clouds. We stayed in a cozy cabin near the river, and every morning began with a hot cup of chai and a view of snow-capped peaks. I even tried paragliding for the first time! At first, I was terrified, but the experience turned out to be magical.

You would’ve loved the local food and the tastiest Maggi I’ve ever had. We also went on a trek to ABC Valley, and though it was exhausting, the scenery made it all worth it. I’m sending some pictures along with this letter. Let’s plan a trip together soon, maybe during the winter break?

I'm waiting to hear all about what you’ve been up to. Write back soon!

Lots of love, 

Megha
