Why is the spacing after a complimentary close four spaces?

If your boss asked you to compose a business letter for him or her, she or he would expect the letter to not only have the right content, but it should also be typed in the appropriate format for a business formal letter. The typist will type the date first and then space down three times to type the name of the recipient as well as their address.

Then the typist will skip down two spaces and type “Dear” and the name of the recipient followed by a colon. Then the typist will space down two more times. Then the typist will type the content. After that the typist will space down two spaces and type “sincerely” or the closing and then the typist will leave four spaces so the writer can sign his or her name.
