Informal Letter Format: A Complete Guide for Students (Class 7 to 10)

Writing an informal letter to a friend, cousin, or family member may seem easy, but many people struggle with the correct format when they start writing. Should the address be placed on the left or right? How do you end an informal letter properly? And what makes a good opening line? Understanding the correct informal letter format can help you write clear, personal, and well-structured letters with confidence.

This guide answers all of that clearly. Whether you are preparing for a class exam or writing your first personal letter, you will find everything you need here – including class-wise tips, a real sample with explanations, and the mistakes most students quietly make.

So, What Exactly Is an Informal Letter?

An informal letter is a personal letter written to someone you share a close relationship with – a friend, a relative, a classmate, or a family member.

Unlike a formal letter (which follows a strict structure and professional tone), an informal letter lets you write the way you would naturally talk. The language is casual, warm, and personal. You can joke, share news, ask questions, and even go off-topic and that is completely fine.

Key features of an informal letter:

• Written to people you know personally
• Uses a conversational, friendly tone
• Does not follow rigid formal language rules
• Can cover any topic – a trip, a birthday, school life, feelings, invitations, and more
• Signed with your first name or a nickname

The Complete Informal Letter Format – Explained Part by Part

The informal letter format consists of seven main parts, and each section plays an important role in making your letter clear, organized, and easy to read. From the sender’s address and date to the greeting and closing, every element helps create a well-structured informal letter. Let’s explore each part one by one and understand its purpose in the letter-writing process.

1. Sender’s Address

Your address goes at the top left of the page. Write it in 3-4 lines, starting from the most specific detail (house/flat number) to the most general (city and pin code).

Example:

42, Rose Garden Colony

Sector 5, Rohini

New Delhi – 110085

Do not write your name here. The address alone is enough.

2. Date

Write the date just below the address, leaving one line gap.

Accepted formats:

• 12th May, 2025
• 12/05/2025
• May 12, 2025

Any of these formats is acceptable. Just stay consistent — don’t mix them.

3. Salutation (Greeting)

This is how you address the person you are writing to. Keep it personal and warm.

Common salutations:

• Dear Aman,
• My dear Priya,
• Dearest Grandma,
• Dear Uncle Rakesh,

Always put a comma after the salutation. If you are writing to someone slightly older or more senior (but still known to you), “Dear Mr Sharma,” works too.

4. Opening Paragraph

Start with a warm line – ask about the person’s health, mention how long it has been since you last met, or refer to their last letter. This sets a friendly tone before you get to the main point.

Good opening lines:

• “I hope you and the family are doing well.”
• “It was great to receive your letter last week.”
• “I’ve been meaning to write to you for a while now!”

Avoid starting with “I am writing this letter to tell you…” it sounds stiff and robotic.

5. Body of the Letter

This is where you write the actual content – the purpose of your letter. You can cover multiple things: sharing news, asking a favour, describing an experience, or making plans.

Keep the paragraphs short and the tone natural. Write the way you speak to this person. If you are sharing multiple things, use a new paragraph for each idea.

6. Closing / Conclusion

Wrap up warmly. Let the reader know you are expecting a reply, or simply end on a positive note.

Good closing lines:

• “Looking forward to hearing from you soon.”
• “Hope we get to meet soon. Take care!”
• “Do write back – I miss hearing from you.”

7. Subscription (Sign-off) and Signature

The sign-off goes below the closing line. Use something warm and appropriate for your relationship.

Common sign-offs:

• Yours lovingly,
• With love,
• Yours affectionately,
• Your friend,
• Warmly,

Then write your first name (or nickname) just below it.

Dear Rahul,

I hope you are doing well and enjoying your summer vacation. How is everyone at home? It has been a long time since we last met, and I have been thinking about you a lot.

I wanted to share some exciting news with you. Last week, I participated in an inter-school science exhibition and won first prize for my project on renewable energy. It was a wonderful experience, and I learned many new things during the event.

Apart from that, I have also joined a cricket coaching camp during the holidays. The training sessions are very interesting, and I am improving my batting skills every day. I wish you were here so that we could play together again.

How are your studies going? Have you made any plans for the upcoming holidays? Do write back and tell me about your recent activities and experiences.

I am looking forward to hearing from you soon. Please convey my regards to your parents.

Yours lovingly,

Aman

Informal Letter Format for Class 7, 8, 9, and 10 – Is There Any Difference?

This is something most guides skip entirely, and it confuses a lot of students.

The good news: the core format stays the same across all classes. The seven parts — address, date, salutation, opening, body, closing, sign-off – are consistent whether you are in Class 7 or Class 10.

What changes is the expectation of language quality and depth:

For CBSE students, the informal letter appears under Section B (Writing) in the English exam. The total marks are typically 5, and examiners look at format, content, expression, and accuracy – in that order.

A Sample Informal Letter (With Annotations)

Here is a sample letter, with each part labelled so you understand exactly why it is written that way.

14, Shanti Nagar                          ← Sender’s address (top left)

Lucknow – 226001

10th May, 2025                            ← Date (below address)

Dear Sneha,                               ← Salutation (warm, personal)

I was so happy to get your letter          ← Opening (acknowledges previous contact)

last week! It felt like we had just

caught up in person.

I am writing to tell you about the        ← Body Para 1 (main news)

school trip we had to Agra last month.

It was honestly one of the best trips

I have been on. We visited the Taj Mahal

at sunrise, and it was breathtaking.

The guide told us so many fascinating

stories about Shah Jahan that I had

never heard before.

The funniest part was when our class       ← Body Para 2 (personal detail — adds life)

monitor forgot his lunch box on the bus

and had to share everyone’s tiffin.

We all laughed so much that our teacher

had to shush us near the monument!

I hope your exams went well. Let me        ← Closing (warm, asks for a reply)

know how your results turned out.

Looking forward to hearing from you!

Yours lovingly,                            ← Sign-off

Anjali                                     ← First name only

Notice how the body has two paragraphs – one for the main point and one for a personal touch. That structure makes the letter feel balanced and interesting without being too long.

Informal vs Formal Letter – What’s the Real Difference?

Students often mix up the two. Here is a clear comparison:

Common Mistakes Students Make (and How to Avoid Them)

Even students who know the format well make these errors in exams:

• Writing the address on the right side – the address always goes on the left in informal letters (unlike formal letters in some formats).
• Skipping the date – this is a format mark in exams. Never skip it.
• Using “Respected” in the salutation – that belongs in formal letters. Stick to “Dear” for informal ones.
• Signing off with “Yours sincerely” – this is a formal sign-off. Use “Yours lovingly” or “With love” instead.
• Writing in a stiff, essay-like tone – informal letters should sound like you are talking to someone, not submitting an assignment.
• No closing line – jumping straight from the body to the sign-off feels abrupt. Always add a warm closing sentence.
• Making the body one giant paragraph – break it into 2-3 short paragraphs. It is easier to read and looks more organised.

Tips That Make Your Informal Letter Stand Out in Exams

• Stick to the format every time. Even if the content is brilliant, format errors lose easy marks.
• Use contractions naturally. “I’m,” “it’s,” “you’ve” make the letter feel genuinely conversational.
• Mention one specific detail. Instead of “I had fun,” write “The sunrise view at the fort was incredible.” Specific details make letters memorable.
• Keep the body focused. You don’t need to write everything. Pick 2-3 things to share and write about them well.
• Match the sign-off to the relationship. “Yours lovingly” for close friends and family. “Yours sincerely” is for formal letters – keep it out.

Conclusion

The informal letter format is one of the most student-friendly writing tasks in English – once you understand the structure, it genuinely becomes enjoyable to write.

Remember: address on the top left, date below it, a warm salutation, a friendly opening, an organised body in 2–3 paragraphs, a warm closing line, and a personal sign-off. Whether you are in Class 7 or Class 10, this format stays consistent. What improves is your language and how naturally your thoughts come across.

The next time you write a practice letter, try to write it the way you would actually say it to that person. That is the real secret behind a great informal letter.
