Storage Unit Size Estimator
Storage unit sizes vary from small units for those who just want to put aside a few boxes of extra stuff to medium and large storage units, which can be used in the process of moving house or for storing vehicles. Essentially, there is a storage unit perfect for your every need.
If you’re wondering “What size storage unit do I need?”, this storage unit size guide will help you to both identify the ideal unit size among the storage unit sizes available and to budget accordingly. It’s important that you rent just the right unit size for your needs, to make the most of the space and your budget. Renting a storage unit that’s too small can make it difficult to organize your belongings in the unit. Booking one that’s too big for your needs, on the other hand, means you are paying for a service you are not actually using at full capacity.
How tall are storage units?
Storage units are usually 8′ high, so multiply this by the square footage to get the cubic volume of the unit. For example, a 10’x10′ storage unit, which is one of the most popular unit sizes, has a total volume of 800 cubic square feet. Calculating the total volume of a storage unit helps you better understand how much stuff you can actually store.
