Standard mailbox height

The standard height for a mailbox in the United States is typically between 41 and 45 inches (104 to 114 cm) above the ground. This is specified by the United States Postal Service (USPS) in their publication "Mailbox Installation Guidelines".

The USPS recommends that mailboxes be installed at a height that allows the mail carrier to easily deposit mail into the box without having to bend or stretch. The recommended height range is based on the average height of a mail carrier, which is around 5 feet 6 inches (168 cm).

It's worth noting that some communities or homeowners associations may have their own specific regulations regarding mailbox height, so it's always a good idea to check with your local post office or homeowners association before installing a mailbox.
