What is a common way of formatting a business letter?

Block format is widely recognized as a common way of formatting a business letter. In this format, all text is aligned to the left margin, creating a clean and professional appearance. Each section of the letter, including the date, address, salutation, body, and closing, is neatly separated by a space, which enhances readability. This format is straightforward and commonly used in professional environments because it presents information clearly and concisely without the additional complexity of indentations or varied margins.

While other formats exist, such as modified block format that includes indents for the date, closing, and signature, and indent format where the first line of each paragraph is indented, block format is the most direct and easiest to read at a glance. Letterhead format refers to the printed heading on stationery but does not encompass the complete layout of the letter's content. Therefore, block format remains the most prevalent choice for business communications.
