Writing Professional Letters

     People read business letters quickly. Therefore, get to the point in the first paragraph--the first sentence, if possible. In other words, state what you want up front.

     In this format, which arises from a combination of professional formats, you should single space your letter and use a serif typeface. Skip a line between paragraphs. Because people read business letters quickly, use shorter sentences and paragraphs than you would in a longer document. Sentences should average fewer than twenty words, and paragraphs should average fewer than seven lines.

     Space your letter on the page so that it does not crowd the top. However, if possible, keep your letter to one page. Second pages often are not read. If you have an enclosure, include an “Enclosure” line, as shown below. Be sure to mention the enclosure in the body of the letter. Also, appearing at the end are the names of those to receive copies.
​
     Final paragraphs should tell readers what you want them to do or what you will do for them.
