Letter Writing Format

In general, everyone needs to be aware of the format of letter writing. A letter is composed of different elements that change depending upon its nature. The format for both the types of letters is given below.

Letter writing format of Formal Letter 

A formal letter must adhere to the prescribed format. The letter writing format of a formal letter is as mentioned below:

Sender’s address


Receiver’s address



Body of the letter

Signature line: sender’s name, signature and designation

  • Sender’s address: One of the most essential components, also known as the return address. It is the mailing address of the sender. The address and contact details of the person sending the letter are written here.

  • Date: Immediately after the sender’s address comes the date on which the letter is written. Candidates, while writing the letter in the exam, can follow any of the formats to write the dates: DD/MM/YY OR MM/DD/YY.

  • Receiver’s address: The corresponding address, i.e. the address of the recipient of the mail is written here. Candidates must start with the receivers’ designation followed by the name of the organization and then the full address, Pincode and country (if the information is known).

  • The subject: This highlights the aim of writing the letter. The subject of the formal letter should be very brief (6 to 8 words) and must be preceded by the word ‘Subject’. The receiver, through the subject, understands the purpose of the letter at a glance.

  • Salutation: This is a customary greeting to the recipient of the letter. If the name of the recipient is known, the salutation starts with ‘Dear’ followed by Mr/Mrs/Miss, etc. If the person is unknown or even the gender is not known the recipient can be addressed as Dear Sir/Dear Madam.

  • Body: The most important element of any letter. It furnishes the reason behind writing the letter. For formal letters, candidates should use short, clear, logical paragraphs to state the subject matter. The body of the letter is generally divided into 3 paragraphs:

  1. Introduction that states the main point.

  2. Middle part: Supporting points and details to justify the need and importance of letter writing.

  3. Conclusion: Request for some action or what is expected. 

  • Complimentary Closure: This is to end the letter with respect in a polite manner such as ‘Yours faithfully’, ‘Yours sincerely’, etc.

  • Signature Line: This is the last part where the sender of the letter signs off with his first or last name. The signature line may also include a second line for the title or designation of the sender.

Candidates writing formal letters in the exam must remember the following pointers.

  • Use of colloquial words, short forms, slang language and abbreviations are restricted.

  • The letter must be to the point, precise and clearly indicating the message.

  • The subject line is very important in Formal Letters.

Important Tips For Good Letter Writing

Candidates appearing for competitive exams are encouraged to follow the below-mentioned tips to write a good letter in the examination and fetch good marks.

  • Candidates must be able to identify the type of letter they will write. For example: writing a letter to the Principal asking for leave is a formal letter, but writing a letter to the Principal to catch up after a long time would be an informal letter.

  • Opening and closing of letters must be in the correct manner. Formal letters must open and close in a professional manner while informal letters can be directly addressed to the person with greetings. Even closing the letters is significant. Formal letters always end respectfully and impersonally, whereas informal letters may end with a more personal touch.

  • In formal letters, making clear the purpose of the letter immediately is important. Candidates writing formal letters must make sure to get to the point as soon as possible.

  • A letter is always supposed to be considerate and polite. It is essential to use polite words and civil language in all types of letters, be it formal or informal. Even if the letter is about any complaint, the point must be made in a careful and courteous manner.

  • The length of the letter also holds relevance. In formal letters, the matter should be expressed to the point, precise and short, while the length of the personal or informal letter depends on the message and the relation to the recipient.
