Layout your business letters properly, with space between the title, greeting, each paragraph, conclusion, and your signature. Leave a space between each paragraph and single-space your letter. Leave two spaces before and after your written signature when submitting typed letters. In general, one to three paragraphs on one page is appropriate letter spacing.
