A U-Haul U-Box container is approximately 5 feet wide, 8 feet long and 7.5 feet high.

It provides about 255 to 257 cubic feet of storage space. Each container can hold up to 2,000 pounds. One U-Box generally fits about one to one-and-a-half rooms of belongings.

Note: Dimensions may vary slightly by container model. U-Haul currently uses traditional U-Box containers and newer steel models. The model you receive depends on local availability.

What Fits in a U-Box?

A single U-Box typically holds belongings from a studio apartment or a small one-bedroom move.

  • Furniture and boxes from one to one-and-a-half rooms
  • Belongings from a studio or small one-bedroom apartment
  • A king-size mattress when positioned carefully
  • Small appliances, household items and moving boxes

Larger apartments and homes usually require multiple containers. The total number depends on the amount and weight of your belongings.
