What format should the closing of a business letter follow in full block format?

In full block format, the closing of a business letter follows a left-aligned format, which means that all text, including the closing, is aligned to the left margin of the page. This format is preferred for its simplicity and professionalism, creating a clean and organized appearance that enhances readability.

When using full block format, there is no indentation for the paragraphs or the closing phrase. Instead, everything, including the sender's name and title, appears flush against the left margin. This uniformity is crucial in business communication as it conveys clarity and attention to detail, important traits in any professional setting.

Other formats like centered or right-aligned would deviate from the full block format's guidelines, potentially leading to a more informal or less professional impression. Indenting from the left margin does not align with the principles of full block format either, as indentation is characteristic of modified formats rather than the full block style.
