What spacing should be applied to paragraphs in a business letter body?

In a business letter, the standard formatting typically involves single-spacing within the paragraphs to create a clean and professional appearance. This helps maintain clarity and readability, preventing the text from appearing too crowded. Additionally, incorporating double spaces between paragraphs provides a visual break, making the letter easier to read and allowing the recipient to see where one idea or section ends and another begins. This formatting is widely accepted and helps ensure that the information is organized and visually appealing in formal correspondence. This approach strikes a balance between professionalism and readability, which is crucial in effective business communication.
