OK, so you need to store some stuff for a period of time in one of U Store It’s self storage facilities, but you don’t know how much space you need and whether 20sq. Ft. Or 200sq. Ft. Don’t be embarrassed, lots of people wouldn’t know a square foot from a round peg and even if you do, it’s difficult to visualise just how much space you need.


Many self storage companies provide a space estimator and we are no different, but we decided to go one step further and produce this simple guide to working out just how much space you’ll need to book.

We have split this out by three factors for ease:

  1. The amount of boxes you need to store
  2. The number of rooms of contents you have to store
  3. The number of trips in a van (of varying sizes) required to move the contents

We hope this provides that little bit of extra help in calculating your self storage needs.

I Have:

  • ~60 Medium Boxes | The Contents Of A Typical Garden Shed/Box Room | One Small Van LoadYou’ll Need At Least A 25sq. Ft. Unit.These units are approx. 5ft x 5ft x 9ft high or 1.5M x 1.5M x 2.7M.When we say a small van we mean a small commercial vehicle, like a Ford Escort Van (car in front, van in the back), otherwise known as a Luton Van.
  • ~115 Medium Boxes | The Contents Of A 1 Bed Apartment | Two Transit Van LoadsYou’ll Need At Least A 50sq. Ft. Unit.These units are approx. 10ft x 5ft x 9ft high or 3M x 1.5M x 2.7M.So if you think you’ll need to make two trips in a typical transit van then this is the unit size for you.

We have many more size options than listed above with many in between these sizes and also larger than 200sq. Ft., but the above gives you a good idea and if you have something in between what is shown above then you can simply pick an intermediate size.
