Understanding USPS Extra Large Flat Rate Boxes
When it comes to affordable, predictable shipping, USPS Priority Mail Flat Rate Boxes are a popular choice for both individuals and businesses. But what about large or extra large shipments? In this article, you’ll learn everything you need to know about the largest flat rate boxes the USPS offers, how they work, their sizes, prices, and practical tips for getting the best value.
What is a USPS Extra Large Flat Rate Box?
The United States Postal Service doesn’t officially call any of its products “Extra Large Flat Rate Box.” Instead, the largest size available in the Flat Rate Box category is the Large Flat Rate Box. Sometimes, people refer to this as an “extra large” box because it’s the biggest in the flat rate lineup.
Key Features of USPS Large Flat Rate Boxes
- One-size cost: Ship anything that fits for a fixed price, regardless of weight (up to 70 lbs) and domestic distance.
- Speed: Priority Mail delivery time, typically 1-3 business days within the U.S.
- Convenience: Free boxes available at your local post office or by ordering online.
Sizes and Types of Large Flat Rate Boxes
USPS offers two main versions of the Large Flat Rate Box:
1. Standard Large Flat Rate Box
- Dimensions: 12-1/4″ x 12-1/4″ x 6″
- Design: Cube-like, which makes it ideal for bulkier or multiple items, including board games, large books, or clothing.
2. Large Flat Rate Board Game Box
- Dimensions: 23-11/16″ x 11-3/4″ x 3″
- Design: Long and flat, perfect for board games, artwork, calendars, or other elongated items.
Tip: There’s no “extra large” size beyond the above two in the Flat Rate category. If your item doesn’t fit, you’ll need to look at regional rate boxes or standard Priority Mail shipping by weight and size.
How USPS Large Flat Rate Shipping Works
Shipping with a Large Flat Rate Box is simple. Here’s how the process works:
- Get a Box: Pick up a free Large Flat Rate Box at the post office or order through the USPS website.
- Pack Your Item: Fit your contents safely into the box. There’s no need to weigh the package, as long as it’s under 70 lbs.
- Seal and Label: Secure the box and fill out a Priority Mail shipping label.
- Pay Flat Rate: You pay a predetermined amount, whether the box travels near or far within the United States.
- Ship: Drop off at any USPS location, leave for your mail carrier, or schedule a pickup.
Benefits of Using USPS Large Flat Rate Boxes
Flat Rate boxes offer several important advantages for shippers:
- Budget-Friendly Shipping: The price is the same regardless of weight (up to 70 lbs) or distance, so you can ship heavy items without worrying about surprise costs.
- Time-Saver: No need to calculate shipping rates for each destination—just use the flat rate.
- Free Packaging: USPS provides the boxes at no cost.
- Tracking & Insurance: Includes USPS Tracking and up to $100 insurance (for domestic shipments).
- Expedited Delivery: Priority Mail service means deliveries typically arrive in 1-3 days.
Challenges and Considerations
While large flat rate boxes are convenient, they aren’t always the cheapest or most efficient option. Consider the following:
- Size Limitations: If your item is too big for the box, you’ll need to use another service.
- Weight Minimum: For lighter items, standard Priority Mail (calculated by weight and distance) is often cheaper than flat rate.
- International Shipping: Flat rate applies to many countries, but rates and conditions differ. The Large Flat Rate Box has a separate international price.
- Not for Hazardous Materials: Certain items, such as aerosols or lithium batteries, are not allowed in Priority Mail or Flat Rate boxes.
Comparing Savings: When Is a Large Flat Rate Box Worth It?
Let’s look at scenarios when using a Large Flat Rate Box saves you money:
- Heavy Shipments: When you’re sending dense materials, books, or anything over 4-5 lbs across the country.
- Shipping Long Distances: Flat rate eliminates the cost difference for shipping from coast to coast.
- Multiple Lightweight Items: If you need to send several light objects together, the box can be a deal.
When Not to Use:
– For lightweight packages staying close by—regular Priority Mail or even First-Class mailing may cost less.

The standard Large Flat Rate Box measures 12-1/4″ x 12-1/4″ x 6″. There’s also a “Board Game” version, which is 23-11/16″ x 11-3/4″ x 3″. Both are considered the largest flat rate box options offered by USPS.
2. Is there a weight limit for USPS Large Flat Rate Boxes?
Yes. The maximum weight allowed is 70 lbs for domestic shipments. Exceeding this weight means the package will not be accepted for flat rate shipping.

No. You must use USPS-branded Flat Rate boxes for flat rate pricing. Using your own box will result in pricing based on weight and distance.
5. Can I send a Large Flat Rate Box internationally?
Yes, but there are different rates and some restrictions. International rates start much higher than domestic, and certain countries or items may not be eligible. Always check USPS international shipping guidelines and rates before sending your package abroad.
