What is the preferred font size for official correspondence?

The preferred font size for official correspondence is 12. This size is commonly chosen because it strikes a balance between readability and space efficiency, ensuring that documents are easy to read without taking up excessive amounts of paper. A font size of 12 is generally considered standard across many official documents, making it widely accepted for professional communication. It maintains clarity, which is essential when conveying important information, and aligns with the formatting standards outlined in various military correspondence guidelines. Furthermore, using a consistent and recognized font size helps maintain a uniform appearance in documents, which is crucial in official communications within the Marine Corps and other formal contexts.
