Business Letter Format Guide & Templates
3 templates — Standard business letter format with examples — inquiry, complaint, and proposal letters. Learn how business letters differ from cover letters.
Overview
A business letter is a formal written communication between organizations or between an organization and an individual. It is used for inquiries, proposals, complaints, confirmations, and many other professional purposes. Unlike a cover letter (which accompanies a job application), a business letter can initiate or continue almost any professional correspondence. The standard format follows the block style: everything flush left, single-spaced within paragraphs, double-spaced between them.

Frequently Asked Questions
What is the standard font and size for a business letter?
Times New Roman or Arial in 11–12 point size is standard. Use 1-inch margins on all sides. The letter should be single-spaced with a blank line between paragraphs.
Should I use letterhead for a business letter?
If you are writing on behalf of a company, yes — use official letterhead which typically includes the company name, logo, address, and contact info. For personal business letters, simply type your address at the top.
How long should a business letter be?
One page is ideal. If you must go to two pages, use a header on the second page with the recipient's name, page number, and date. Never let your letter run to three pages — revise for conciseness.
Is email considered a business letter?
Email can function as a business letter if formatted properly, but a traditional business letter carries more weight for formal matters like legal notices, complaints, or high-stakes proposals. Use printed letters when formality matters.
What does 'CC' mean at the bottom of a business letter?
'CC' stands for 'carbon copy.' It lists other people who are receiving a copy of the letter. 'Enclosures' (or 'Enc.') indicates that additional documents are included with the letter.
