What are the dimensions of a letter sized document?

The dimensions of a letter-sized document are 8.5 inches by 11 inches. This standard size is widely recognized and commonly used for letters, documents, and various printed materials in the United States. It falls under the International Organization for Standardization (ISO) and has become the default format for business and personal correspondence.

This size facilitates easy reading and allows for efficient use of space when printing or copying, making it ideal for reports, resumes, and other types of documents that need to be easily handled and stored. The other dimensions presented are related to different standard paper sizes but do not align with the letter-sized specification. For example, 8.5" x 14" corresponds to legal size, while 11" x 14" is not a standard size in common use for documents. Thus, 8.5" x 11" is the correct answer, reflecting the norm for letter-sized documents.
