Informal Letter Format 

In this section, we will explain the informal letter format and show you how to write one in detailed steps

1. Sender’s Address:

You need to start with your address at the top left of the page. Include the street, city and postal code. Skip a line before moving on to the next part.

2. Date:

Here comes the second step. Now, you need to put the date below your address. Use a standard format like “28th June 2024″ to clarify.

3. Salutation:

Start with a friendly greeting. Typical examples are “Dear [Name]” or “Hi [Name],”. Use a comma after the name. If you’re addressing it to an elder, you can use ‘respected.’ 

4. Body:

Now, you have come to the main content of your letter. There should be three paragraphs:

  • Introduction: Start with a friendly opening. Ask about their well-being or share a recent experience with them. You can let them know how you’re doing. 
  • Primary Content: Move to the main reason for writing. This can be anything from sharing recent news to asking for advice, inviting them to an event, etc. 
  • The end: Conclude your thoughts. You hope to hear back soon and express good wishes and love. 

5. Closing:

End your letter with a warm closing phrase like “Yours lovingly,” “Best wishes,” or “Take care,” followed by a comma.

You must remember that the tone of an informal letter is conversational and personal. 

What is the difference between Formal and Informal Letters?

Many students confuse Formal and informal letters when they first learn them in their curriculum. Formal and informal letters differ in their tone, structure and purpose.

Formal Letters are used for professional or official communication. They follow a strict format with the sender’s address, date, recipient’s address, salutation, body, closing and signature. 

The language is formal and respectful. It’s usually used in business, academic, or official contexts. It can include a letter to the principal, librarian, or complaint letter. 

Informal Letters are used for personal communication with friends, peers, or family. They have a relaxed structure, including the sender’s address, date, salutation, body and closing, and the tone is informal and friendly. 

The content is more personal and can consist of sharing news, experiences, invitations, sending presents, etc. 

You can say that formal letters focus on professionalism and clarity, while informal letters are based on a personal and friendly tone.
