Letter Writing Format for Class 10: A Complete Guide

Why the Letter Writing Format Matters in the Board Exam

A student can know perfect English and still lose marks in the board examination on the letter-writing question. The reason is rarely grammar. It is the format. In the Class 10 English paper, the examiner checks the layout first and the language second, and a letter with the parts in the wrong order, a missing subject line, or the wrong closing can lose marks before a single sentence is read. The good news is that the format never changes. Once a student learns the seven parts of a formal letter and the order in which they appear, every letter question becomes the same exercise with different content.

Letter writing for 10th standard is a fixed part of the writing section. In the CBSE Class 10 English paper, the formal letter question carries 5 marks, and the question usually gives a choice between two situations, such as writing to a principal, an editor, or a public official. The student picks one situation and writes the letter in about 100 to 120 words, and the format stays the same from year to year, so a student who practises it a few times walks in with those marks nearly secured.

This guide explains the complete letter writing format for Class 10, part by part, with a full sample letter and the common mistakes that cost marks.

Letter Writing Format at a Glance

A formal letter has seven parts, and they always appear in the same order:

1. Sender’s address — the writer’s own address, at the top left of the page.
2. Date — written below the sender’s address.
3. Receiver’s address — the address of the person or office the letter is going to.
4. Subject — one short line stating the purpose of the letter.
5. Salutation — the greeting, such as Respected Sir or Madam.
6. Body — the main message, usually in three short paragraphs.
7. Complimentary close — the ending, such as Yours faithfully, followed by the writer’s name.

The sections below explain each part one by one.

Formal Letter vs Informal Letter

Class 10 students are tested on the formal letter, but confusing the two formats is one of the most common errors. The difference is simple: a formal letter is written to a person the writer does not know personally — a principal, an editor, a public official — while an informal letter is written to someone the writer knows well, such as a friend or a family member.

A formal letter follows the seven-part structure above, uses polite and precise language, and avoids contractions, slang, and personal remarks. The tone is respectful throughout, and the purpose of the letter is stated clearly in the subject line so the reader knows what is being asked before reading the body.

An informal letter is looser. It has no receiver’s address and no subject line, and it begins with the sender’s address and the date, followed by a warm greeting such as Dear Mother or Dear Rahul. The body is conversational, the language is relaxed, and the letter ends with a friendly closing such as With love or Yours lovingly. The two styles must never be mixed.

The 7 Parts of a Formal Letter, Explained One by One

1. Sender’s Address

The sender’s address goes at the top left corner of the page. It is the address of the person writing the letter, written in three or four short lines without a name above it. In the board examination, students must not write their real address. The question paper usually gives an imaginary address, or the student writes a general address such as Examination Hall, followed by the city. A real name or a real address in an answer script is not expected, and writing one is a mistake students should avoid.

2. Date

The date comes directly below the sender’s address, on the left side of the page. It should be written in full, such as 7 November 2026, rather than in figures such as 07/11/2026. Students should write the date of the examination day, or the date given in the question.

3. Receiver’s Address

The receiver’s address is the address of the person or office receiving the letter. It goes below the date, on the left side, and it begins with a title such as The Principal, The Editor, or The Municipal Commissioner, followed by the name of the institution and the city. A letter to the principal, for example, is addressed like this:

4. Subject

The subject is a single line that states the purpose of the letter in a few words. It is written below the receiver’s address and usually begins with the word Subject. A good subject line is short and specific. “Request for leave” is better than “Regarding something important”, and “Permission to participate in the inter-school debate competition” is better than “Request”. The subject line helps the reader understand the letter at a glance, and in the examination it shows the examiner that the student understood the question.

5. Salutation

The salutation is the greeting that opens the letter. In a formal letter, the standard greeting is Respected Sir or Madam, or Dear Sir or Madam. Students writing to a principal may write Respected Sir, and writing to an editor usually takes Dear Sir or Madam. The greeting should never be casual. Hello, Hi, or Dear friend have no place in a formal letter.

6. Body of the Letter

The body is the message itself, and it is usually written in three paragraphs. The first paragraph introduces the writer and states the purpose of the letter in one or two sentences. The second paragraph gives the details: the dates, the reasons, and the facts the reader needs. The third paragraph closes the request politely, often with a sentence such as “I shall be grateful if you grant my request” or “Kindly look into the matter at the earliest.” Each paragraph should be short, and the body as a whole should stay within the word limit of about 100 to 120 words. A clear body does three things and nothing more: it says who is writing, it says what is needed, and it says why. Students who practise with the question papers published by the Central Board of Secondary Education will find that the letter questions follow the same pattern every year.

7. Complimentary Close

The complimentary close is the polite ending of the letter. For a formal letter, the standard close is Yours faithfully, followed by the writer’s name on the next line. If the letter is addressed to a known person by name, the close is Yours sincerely. Students writing in the examination should sign off with a general name such as XYZ or their roll number, as the question paper directs, and never with their real name. The close is followed by the name, the class and section, and sometimes the roll number, each on its own line.

A Complete Sample Letter to the Principal

The letter to principal format is the most common letter question in Class 10. The sample below is a letter requesting permission to take part in an inter-school debate competition, and it follows the seven parts in order.

Examination Hall,
New Delhi

7 November 2026

The Principal,
Government Senior Secondary School,
New Delhi

Subject: Permission to participate in the inter-school debate competition

Respected Sir,

I am XYZ, a student of Class X-A, and I am writing to seek your permission to participate in the inter-school debate competition to be held at St. Mary’s School on 20 November 2026.

Our school’s debate team has been invited to send two speakers, and my English teacher has selected me as one of them. The topic of the debate is the role of technology in education, and the competition will take place during school hours, from 10 a.m. to 1 p.m.

I request you to kindly grant me permission to attend the competition and to treat my absence during those hours as leave for a school activity. I shall be grateful for your support.

Yours faithfully,
XYZ
Class X-A
Roll No. 12

Students can use this letter as a model and change the details — the event, the date, and the request — to fit any question the examination sets. The structure stays the same: the format is the skeleton, and the content is whatever the question asks for. A letter asking for leave follows the same seven parts, and the guide to a leave application for school shows how the structure works for a leave request, while a sick leave application follows it for a health-related absence. The same pattern also appears in an application for a transfer certificate, another formal letter to the principal with a different purpose.

Common Mistakes That Cost Marks in the Board Exam

Most of the marks lost on the letter question are lost on small errors, and nearly all of them are easy to avoid.

• Writing the parts in the wrong order. The sender’s address comes first, then the date, then the receiver’s address. A letter that begins with the date or places the subject before the receiver’s address has the format wrong.
• Forgetting the subject line. The subject is one of the seven parts, and leaving it out costs format marks. Every formal letter needs a subject.
• Using the wrong closing. Yours faithfully is the close for a formal letter to an unknown person. Yours lovingly or With love belongs to an informal letter.
• Writing the real name and address. Answer scripts must not carry a student’s real identity. Students should use the address and name given in the question, or a general placeholder such as Examination Hall and XYZ.
• Exceeding the word limit. The letter should be about 100 to 120 words. A letter that runs to 200 words is not better; it shows the student could not keep to the limit, and it wastes time that other questions need.
• Mixing formal and informal language. Contractions such as don’t and can’t, slang, and casual phrases do not belong in a formal letter. The language should be polite and complete throughout.
• Poor handwriting and no spacing. Clear handwriting, a blank line between paragraphs, and the parts separated as the format requires make the letter easy to read and easy to mark.
• Adding a postscript. A postscript has no place in a formal letter. Anything the student forgot belongs in the body, in the right paragraph, not after the signature.

A student who checks the letter against this list before moving on will catch most of these errors in a few seconds, and that short check is often worth a mark or two.

How to Practise Letter Writing Before the Exam

The format is learned by writing, not by reading about it. A student who writes five or six letters before the examination will have the format in memory, while a student who only reads it once will still be thinking about the order of the parts during the paper.

The best practice is to take the letter questions from the last three years of board papers and write each one in full, in about 100 to 120 words, without looking at the format notes. After writing, the student checks the letter against the seven parts and the mistakes list above. The first two letters take time; by the fifth, the format comes automatically.

Students should also practise the two most common situations: a letter to the principal, which asks for something such as leave or permission, and a letter to the editor, which raises a concern such as the condition of a park. Both follow the same seven parts; only the receiver’s address and the body change. Before writing, a student should spend a minute deciding the subject line and the three points of the body: the introduction, the details, and the closing request. A letter planned in a minute is written in ten minutes and reads better than a letter started without a plan.

Frequently Asked Questions

What is the format of a formal letter for Class 10?

A formal letter for Class 10 has seven parts in a fixed order: sender’s address, date, receiver’s address, subject, salutation, body, and complimentary close. The sender’s address and the date go at the top left, the receiver’s address follows, then the subject line, the greeting, the body in about three paragraphs, and finally the closing with the writer’s name.

How many marks does letter writing carry in Class 10?

In the CBSE Class 10 English paper, the formal letter question carries 5 marks. The letter is expected to be about 100 to 120 words long, and the marks are given for the format, the content, and the accuracy of the language.

What is the difference between a formal and an informal letter?

A formal letter is written to a person the writer does not know personally, such as a principal or an editor, and it follows a strict seven-part format with polite language. An informal letter is written to a friend or a family member, has no receiver’s address or subject line, and uses a relaxed tone with a friendly closing.

How do you write a letter to the principal?

A letter to the principal follows the formal letter format. It begins with the sender’s address and the date, then the principal’s address, a subject line stating the purpose, a greeting such as Respected Sir, a body in three paragraphs that introduces the writer, gives the details, and closes with a polite request, and ends with Yours faithfully and the writer’s name, class, and roll number.

What are the common mistakes in letter writing for Class 10?

The most common mistakes are writing the parts in the wrong order, forgetting the subject line, using the wrong closing, writing the real name and address instead of a placeholder, exceeding the 100 to 120 word limit, and mixing formal and informal language. Checking the letter against the seven parts before moving on catches most of these.

Students who know the format can focus on the content, and that is where the marks are won. The seven parts never change, the word limit never changes, and the two most common situations — a letter to the principal and a letter to the editor — appear year after year. A few practice letters before the examination are enough to make the format automatic.
