What should the left, right, and bottom margins of a standard letter be set to?

The correct setting for the left, right, and bottom margins of a standard letter is 1 inch. This standard margin size is widely accepted as it provides a clean and professional appearance, ensuring that text is not too close to the edges of the page. It allows for adequate space for binding or filing and contributes to readability by preventing the text from feeling cramped.

Using 1-inch margins is common in formal correspondence, as it adheres to guidelines set forth by various style manuals and professional standards in business and academic writing. Margins that are too small may compromise the visual appeal and readability of a document, while those that are excessively large can reduce the amount of information that fits on a page, leading to inefficiency in communication. Thus, the 1-inch margin strikes an ideal balance for a standard letter.
