If you have ever felt confused about letter writing, you are in the right place. In this complete guide, I will teach you everything you need to know about how to write a letter in English both formal and informal with clear examples and simple steps.
What is a Letter?
A letter is a written message sent from one person to another. Before emails and WhatsApp existed, letters were the main way people communicated with each other. Even today, letters are extremely important in professional and academic life.
Letters are used for:
- Applying for jobs
- Writing to schools and universities
- Complaining about a product or service
- Requesting information
- Writing to friends and family
- Official government communication
Types of Letters
There are two main types of letters in English:
1. Formal Letter
A formal letter is written in a professional and official tone. It is used for business, job applications, complaints, requests, and official communication. The language is polite, serious, and structured.
Examples of formal letters:
- Job application letter
- Complaint letter
- Request letter
- Letter to a school principal
- Business letter
2. Informal Letter
An informal letter is written to someone you know personally — a friend, family member, or relative. The tone is friendly, warm, and casual. You can use everyday language and expressions.
Examples of informal letters:
- Letter to a friend
- Letter to a cousin
- Letter to a pen pal
- Thank you letter to a family member

It has been such an amazing experience and I am
learning so much every day. I wish you could visit
my blog and tell me what you think!
This month has been quite busy for me. I have been
studying for my exams, working on my blog, and also
helping my mother at home. Despite being busy, I am
really enjoying everything. I feel like I am growing
so much as a person.
How are your studies going? Are you preparing for
your exams? I remember how stressed we both used to
get before exams in school! I hope things are going
smoothly for you.
I really hope we can meet soon. Maybe we can plan a
get-together during the summer holidays. Please give
my love and regards to your parents and siblings.
I am looking forward to your reply!

Common Mistakes in Letter Writing
Mistake 1 — Using the wrong closing Many students use "Yours sincerely" when they have written "Dear Sir" — this is wrong. Use "Yours faithfully" when you do not know the name.
Mistake 2 — Forgetting the subject line in formal letters Always include a subject line in formal letters. It tells the reader exactly what the letter is about.
Mistake 3 — Being too casual in formal letters Avoid using words like "gonna," "wanna," or "btw" in formal letters. Keep the language professional.
Mistake 4 — Writing too long paragraphs Keep each paragraph focused on one idea. Long paragraphs are difficult to read.
Mistake 5 — Not proofreading Always read your letter again before sending. Check for spelling mistakes, grammar errors, and unclear sentences.
Mistake 6 — Wrong date format Always write the date in full: 23 May 2026 — not 23/05/26.
Useful Phrases for Letter Writing
For formal letters:
- I am writing to inform you that...
- I would like to request...
- I am pleased to inform you that...
- I regret to inform you that...
- I look forward to hearing from you...
- Please do not hesitate to contact me...
- Thank you for your time and consideration...
For informal letters:
- It was so good to hear from you!
- I hope this letter finds you in good health...
- I have so much to tell you!
- I miss you so much!
- Write back soon!
- Give my regards to everyone at home...
- I cannot wait to see you!
Frequently Asked Questions About Letter Writing
Q1: What is the difference between "Yours sincerely" and "Yours faithfully"? Use "Yours sincerely" when you know the name of the person you are writing to (Dear Mr. Ahmed). Use "Yours faithfully" when you do not know the name (Dear Sir or Dear Madam).
Q2: Should I write my name at the top of a formal letter? No. In a formal letter, you write your address at the top — not your name. Your name goes at the bottom after your signature.
Q3: Can I use contractions in a formal letter? No. In formal letters, always write the full form: "do not" instead of "don't," "cannot" instead of "can't," and "I am" instead of "I'm."
Q4: How long should a formal letter be? A formal letter should be concise and to the point. Usually one page is enough — three short paragraphs covering the introduction, details, and request or conclusion.
Q5: Is a subject line necessary in an informal letter? No. Subject lines are only required in formal letters. In informal letters, you go straight to the salutation and body.
Q6: Can I write a formal letter by hand or must it be typed? For school and exam purposes, handwritten formal letters are perfectly acceptable. In professional settings, typed letters are preferred. However, the format and structure remain the same in both cases.
Q7: What should I do if I do not know the gender of the person I am writing to? Use "Dear Sir/Madam" or "To Whom It May Concern" as your salutation. This is a safe and professional option when you are unsure.
