What spacing is typically used between paragraphs in a letter?

In a formal letter, the standard practice is to use double spacing between paragraphs. This spacing allows for clear readability and gives the document a neat, professional appearance. Double spacing helps to visually separate sections of the letter, making it easier for the reader to follow the flow of information.

This format is particularly valued in business communication, as it projects professionalism and attention to detail. The additional space can also provide a margin for annotations or comments, should the document need to be reviewed or edited. While other spacing options exist, such as single space, triple space, and half space, they are not typically utilized in formal letter writing, which explains the preference for double spacing.
