Proper Format of Letters: How to Write Business Letters Correctly

Business Letter Writing Tips

What comes to mind when you hear the phrase business letter? Will a white envelope with fancy letterhead and stuffy writing come to mind? In many cases, you are right. Even if almost everything is done via email today, business letters are not yet extinct or are considered to be completely out of date so it still pays to know how to write and format them correctly.

Part of a Standard Business Letter Format

As you might learn in elementary school, business letters consist of different parts. This section covers what is included in each section and the correct format of the business letter.

Sender’s Information

It’s important to know how to handle business letters correctly, especially if you expect a reply. This section includes your full address, telephone number, and e-mail address. Some people like to include their full names at the top of this list, but some people consider them excessive because you will sign a letter with your name. You do not need to include this if the paper you are using has letterhead. What must be included and formatted:

  • Street address
  • City, Country, Postal Code
  • Country (if not in the same country as your recipient)
  • Your telephone number
  • Your email

Today’s Date

Spell the month and include the full year. Write the month, date, and year if you are sending a business letter in the US, but start the date with a day (for example 18 October 2018) if you are sending a letter in the UK or Australia.

Address Information (a.k.a. Inside Address)

Include recipient information, starting with their names, followed by their title and full address. Handle the recipient using Ms., Mr., or use a title that is appropriate for whatever job is required

  • Name
  • Job Title
  • Company Street Address
  • City, Country, Postal Code
  • Country (optional)


The greeting used at the receiving end does not have to be the same as the one used here. It all depends on how close or familiar you are with the address, and the context of your letter. The Dean at the College of Science might be your aunt, but if you write to him in an official capacity, it’s better if you use the greetings “Dean (Last Name)” or “Dr. (Last Name)” because there is a possibility of someone else handling his correspondence. Military and religious titles must be written as is.

Not sure about the gender of the recipient? Do not use Mr. or Ms., just write “Dear” followed by their full name. If you don’t know who the person you are actually calling, “To Whom May Concern” will be done. You can also contact the department or group that will handle your letter, such as “Recruitment Committee Members” or “Condominium Association Management.” Always end the greeting with a colon, not a comma.

Body Text

The body of the letter usually consists of one to three short paragraphs, each with a specific purpose and organized for clarity.


Explain the reason for the letter and what you want to achieve with it. If the recipient does not know who you are, you can also mention the reciprocal relationship here.

Second paragraph

Provide more details about your request, such as steps you have taken or fees paid. In the case of marketing or job applications, the second paragraph is where you will sell the product you are promoting or your application.

Third paragraph

Optional and included in situations where the second paragraph is not enough to explain the situation in full.

Closing includes one or two sentences asking the recipient to take whatever action is requested in your letter, and thank you for reading your letter.

Example of closing a business letter:

Please email me at (your email) or contact me at (your business telephone) to schedule a meeting. Thank you for your consideration. If you need to discuss anything with me or the team, please don’t hesitate to contact us at (your phone). We are always at your service.

Close Free

Free closing is a sign-off phrase that is entered before your signature. You have many choices here, but in general you should avoid showing appreciation or gratitude in letters where you don’t ask for anything.


  • Regards
  • Best regards
  • With respect
  • With gratitude
  • With appreciation

The Signature

Sign the letter under the free cover. Be sure to leave at least four spaces between your name and close so there is enough space for your signature. You might want to enter your job title, telephone number, and email address under your full name too.

  • Signature
  • Attachment

Before the age of the email, people wrote “Attachments” at the bottom of the business letter to indicate that the envelope included other documents. Think of it as the printed version “see attachment” for email. Attachments are noted at the bottom left of the letter, some space under your signature, followed by a list of documents included. As an example:


  • Brochure
  • Order form

1. Full Block

Full block is the most common format for business letters because it’s the easiest. You don’t need to worry about indenting and everything is justified. A single space is used instead of indenting for a new paragraph.

2. Modified

The modified format is rather difficult to remember because not everything is justified. Addresses, greetings, and letter bodies are confirmed, while the sender’s address, date, free cover, and signature are aligned to the right.

In the example below, there are two spaces between the sender’s address and the date when the letter was written and three spaces between the recipient’s address and the greeting. There are also two spaces between the first paragraph of the body of the letter and greetings and two spaces for each new paragraph.

The free closing sign, the signature, and the last paragraph of the letter are two separate spaces. Below is an example of a business letter in a modified format from Savvy Business Correspondence: letter format

3. Indexed

The indent or semi-block format is similar to the modified format, except that the beginning of each paragraph has an indent.

Formatting Business Letters and Design Tips

Your business letter needs to make a good first impression, because in some cases, reading the letter will be the first time the recipient “finds” your company.

1. Professional Letterhead

The company isn’t the only one who can use letterhead. Solopreneurs, job applicants, and anyone who wants to create a brand for themselves can use letterhead to make their letters unique. Letterhead can also be used to verify the authenticity of documents to recipients, which often happens for government letters and bank letters.

The design of letterhead is diverse, the only thing that is consistent is that it must include your company name and logo, address, and contact information. If you don’t have a logo or company name, just replace it with the part with your full name. Because business letters are formal, choose a letterhead design that isn’t too busy or colorful so that it reduces the message you send.

Do not use scented stationery or paper. Want to make your own letterhead? See this template from Envato:

2. Margin of Business Letters

It’s best to save the tree, but don’t put too much text into one page that doesn’t have any margins left. Leave 1 “to 1.5” per side.

3. Regular Fonts

Avoid fonts that are fancy and hard to read cursive. Choose Verdana, Arial, Courier New, or Times New Roman with a minimum font size of 12.

4. Formal Letter Spacing

Use one space between paragraphs to make letters easier to read. You must also use at least one space between all letter elements, except between your signature and the printed name where four line breaks are needed.

5. 2-page letterhead for Additional Pages

Business letters must be concise enough to only require one page, but that is not always true. Legal contracts, complaints and advice letters sometimes require additional pages.

To avoid confusion if the letter pages are separate, the second and subsequent pages must include letterhead and page numbers at the top. You might also want to enter the recipient’s name and date.

Type of Business Letter

Business letters are sent for all kinds of reasons. Businesses send it to their customers or to other businesses where they work, such as vendors or logistics partners. Individuals write business letters for business and less formal purposes as well. Here are some examples of types of business letters:

1. Complaints

Not all complaints can be broadcast and handled properly on social media, some topics are a bit sensitive or embarrassing if you don’t want the risk to become viral. Then there are complaints when calls to the company’s customer service hotline are not enough. For all these complaints, a printed complaint letter is the answer.

Keep your complaints short, to the point, and polite. Don’t just make it about the company’s mistakes, tell them what you want them to do about it.

2. Resignation Letter

Resignation letters are what employees send to their superiors when they want to quit their jobs. In many cases, you must allow at least 14 days or two weeks before the official departure date of the company.

Below is an example of a letter of resignation from an American Recruiter: Resignation-letter

Note: If you do not know the sex of the person who will receive your letter, it is better to use general greetings such as “to whom is interested” rather than using “Father / Mother.” or “Sir.”

3. Cover letter

A printed cover letter is sent along with a resume to explain briefly why you are a good candidate for the job. A good cover letter is like an appetizer in the sense that it gives recruiters a taste of what they can expect from you, without having to repeat what is already on your resume. Read this guide for more information on writing a cover letter:

4. Letters of Recommendation

A letter of recommendation is sent to verify the applicant’s good reputation with the previous employer or manager. In some cases, this recommendation is nothing more than a template made by someone from HR after filling in the blanks about the employee’s start and end dates.

If you write a cover letter for good employees, it would be better if you go beyond the template to show that you value your time working together. See this guide if you need help writing a recommendation letter:

5. Letter to Request Information

Letters asking for information are often sent to businesses by individuals or representatives of other businesses when they want information about certain products or services.
