U-Haul U-Box container size

On the inside, where it matters most, U-Box containers measure –

  • 7 feet 11 inches long
  • 4 feet 8 inches wide
  • 6 feet 11.5 inches high

With approximately 257 cubic feet of usable space, you can fit roughly 1½ rooms worth of furniture and boxes in one container.

Just remember that you may run out of space sooner if your loading skills aren’t exactly world-class. So it may be worth hiring professional movers to help you load.

Each container can hold a maximum of 2,000 pounds, but this shouldn’t be an issue unless you’re moving lots of books or your grandpa’s antique paperweight collection.

U-Box containers measure more than 9 feet diagonally, which can come in handy for awkward items like rolled rugs.

What fits in U-Box containers

One of the most commonly asked questions about U-Box containers is if they’re large enough for a king and queen mattresses.

The answer in both cases is usually “yes.”

Averaging about 7 feet long x 6 feet wide, most California king mattresses and box springs will fit, as will –

  • Full-size sofas (average length is about 7 feet)
  • Standard refrigerators (most are about 6 feet tall)
  • Common household items like lamps, furniture, sports equipment, and yard tools
  • Boxed items of clothing, dishes, picture frames and books or movies

What should NOT go in a U-Box container

U-Box containers are made of treated, pest-resistant plywood and covered with a heavy-duty vinyl cover. As a result, the storage container is not temperature controlled, so you should be careful about what you pack in it

Don’t pack:

  • Sensitive paperwork like deeds & documents, including legal and financial documents (passports, visas, birth certificates) 
  • Fur items
  • Firearms
  • High-expense or irreplaceable items like jewelry, watches, artwork, collectibles or, antiques
  • Currency and medications

During transport, containers are loaded inside a truck, so they shouldn’t be in direct contact with snow, sleet, or rain. However, loading or unloading in inclement weather can be an issue, as the containers aren’t technically weather or waterproof.
