What is the minimum number of lines you must leave at the bottom of the page when splitting a letter at the bottom of the page?

The minimum number of lines you must leave at the bottom of a page when splitting a letter typically depends on formatting guidelines or personal preference. Generally, it's recommended to leave at least 2-3 lines clear to ensure that the text does not appear cramped and maintains readability. This also allows for proper spacing for signatures or additional notes if needed. Always check specific formatting requirements if you're following a particular style guide.
