Mailbox Post Tutorial

Mailbox Post Size Considerations

The standard mailbox posts we sell at Star Granite Company are 7 x 7 inches and 7 feet long. We install the posts with two feet in the ground with a five foot reveal. Other post sizes include 6 x 6, 10 x 10, and 12 x 12 inches.

A standard mailbox is just under seven inches in width. Mounting a mailbox on a 7 x 7 inch post allows the mailbox to span the face of the granite post without hanging over the edge of the post. A standard mailbox mounted on a 6 x 6 post, while a bit more economical, tends to overpower the granite post.

Larger posts are recommended if you want to mount two mailboxes or want to mount an oversized mailbox.

TUTORIAL TIP

When comparing estimates from different mailbox post vendors, make sure the post sizes are the same. Some companies sell 6 x 6 inch posts as their default post size.
