Hey neighbor! Did you know that mailboxes come in a range of sizes officially approved by the United States Postal Service? Whether you’re dealing with daily letters or frequent package deliveries, there’s a mailbox size that’s just right for your needs.
The USPS categorizes residential mailboxes into four main sizes, labeled T1 through T4. Here’s a quick breakdown of what each size offers:
T1 – Medium Mailbox
- Dimensions: 6.5″ wide x 8.5″ tall x 18.5″ deep
- Best for: Standard daily mail like letters, magazines, and small envelopes.
This is the most common mailbox size you’ll see around the neighborhood. It’s great if your mail volume is light and you’re not expecting packages often.
T2 & T3 – Large Mailboxes
- Dimensions: 8.5″ wide x 11″ tall x 20″ deep
- Best for: Households that frequently receive small packages.
These mailboxes give you a bit more breathing room. If you regularly receive padded envelopes or small boxes, upgrading to a large size will save you trips to the post office.
T4 – Extra-Large Mailbox
- Dimensions: 13″ wide x 15″ tall x 23.5″ deep
- Best for: Multiple packages, plus your daily mail.
T4 is the “next generation” mailbox — perfect for online shoppers or small home businesses that receive a lot of deliveries. It’s built to hold everything from daily letters to multiple parcel deliveries.
