Format your memo properly. Use a standard format for your memo to ensure that it is easy to read. Use a 12-point font such as Times New Roman or Arial. Use one-inch margins on the left, right and bottom sides. Use block style paragraphs. Double space between paragraphs. Do not indent each paragraph.

The format of a memo follows the general guidelines of business writing. A memo is usually a page or two long, single spaced and left justified. Instead of using indentations to show new paragraphs, skip a line between sentences. Business materials should be concise and easy to read.
