Core Components of a Business Letter
A standard business letter consists of five essential sections: sender's address, date, recipient's address, salutation, body, closing, and signature block. Each element follows a specific placement and spacing rule.
Sender's Address
Place your full mailing address at the top left (or top center for block style). Omit the company name if it appears in the letterhead.
Date
Write the full date (e.g., 23 August 2026) on the line immediately below the sender's address. Use the same alignment as the address.
Recipient's Address
Include the recipient's name, title, company, and full address. Align this block with the left margin, leaving a blank line after the date.
Salutation
Use a formal greeting such as "Dear Mr. Smith:" or "Dear Dr. Lee:". A colon is standard in U.S. business letters; a comma is acceptable in British usage.
Choosing a Layout Style
Three layout styles dominate business correspondence: Full‑Block, Modified‑Block, and Semi‑Block. The table below compares their key attributes.
| Layout | Alignment | Typical Use |
|---|---|---|
| Full‑Block | All lines left‑justified | Most corporate communications |
| Modified‑Block | Sender's address, date, and closing right‑justified | Formal letters where a traditional look is desired |
| Semi‑Block | Body indented 0.5‑1 in. | Personalized business letters, legal notices |
Formatting the Body
The body conveys your purpose. Keep paragraphs short (3‑5 sentences) and use a single‑space line spacing with a blank line between paragraphs. For clarity, follow this structure:
- Opening paragraph: State the purpose of the letter.
- Middle paragraphs: Provide details, supporting facts, or requests.
- Closing paragraph: Summarize action steps and express gratitude.
Font and Size
Use a professional, readable font such as Times New Roman, Arial, or Calibri in 11‑12 pt size. Avoid decorative fonts and excessive bolding.
Closing and Signature Block
Common closings include "Sincerely," "Yours truly," or "Respectfully," followed by a comma. Leave four blank lines for a handwritten signature, then type your full name, title, and contact information.
Electronic Signatures
When sending a PDF, insert a scanned signature image or use a certified e‑signature tool. Ensure the signature appears above the typed name.
Special Cases and Variations
Different contexts demand slight tweaks.
Cover Letters
Include the job title and reference number in the opening paragraph. Align the recipient's address to the left and keep the tone slightly more personal.
Letters of Complaint
Adopt a firm yet courteous tone. Use bullet points to list specific issues and desired resolutions.
International Letters
Follow the recipient's local conventions (e.g., British style uses a comma after the salutation). Include country names in the address block.
