What is the minimum size a letter accepted for domestic mailing?

3 x 5 inches
3.5 x 5 inches
4 x 6 inches
5 x 7 inches

The correct answer is: 3.5 x 5 inches

The correct answer reflects the minimum size requirement for a letter accepted for domestic mailing, which is established by the United States Postal Service (USPS). A letter must measure at least 3.5 x 5 inches to be eligible for mailing. This dimension ensures that the mail piece can be processed efficiently through automated sorting systems in postal facilities. Other sizes mentioned in the options either do not meet the minimum threshold or exceed what is required just to qualify as a letter. Therefore, understanding the specific regulations and dimensions set forth by the USPS is crucial for anyone preparing items for mailing to ensure that they are compliant and to avoid delays or issues with mail delivery.
