Choosing a self-storage unit doesn’t have to be like the fairy tale where you try out every size unit before finally finding one that suits your needs.

Whether you’re looking to store the contents of an entire four-bedroom house or just your seasonal clothing or items, we have a unit that’s just right for you.

But how do you determine what size you need? Read below for just about everything you might need to know:

Take stock

“One of your first questions should be "what will I be storing?”

Take a quick inventory of items including furniture and appliances and estimate the number of boxes and/or totes. You can use a tape measure for the larger items. Consider whether you have irregular-shaped items that can’t be boxed or stacked like lamps or bikes.

Gauge Space Using your Moving Truck

If you’re using a moving truck, the truck’s dimensions can help you estimate how much total storage space you’ll need. The truck size is typically one size larger than the unit size you’ll need, Goodin said.

If you have a 25-foot moving truck, you can fit your items into a 10’x20’. If you have a 20-foot truck, you need a 10’x15.’ If you have a 15-foot truck, you need a 10’x10.’

To Cram or Not to Cram, that is the question....

Do you want to stuff it full, floor to ceiling... or do you need a slightly larger unit to walk around and move items?

For people who are going to store everything and just shut the door and come back in six months when their new home is ready don’t need as big a space, but if you need to access the space, you'll need an aisle or you'll have to take everything out and spread it out to find what you're looking for.

Undecided? Go Big

Many new customers underestimate their needs and choose a unit that’s too small. Sometimes it’s only a few bucks more for the next size up. If you want to get to your stuff easily, go with a unit one size larger and leave a path. Often people need something that's stored in the back of the unit and it takes them several hours to find it, get it out and repack their storage unit.

Understand Dimensions and Square Footage

Typically, units are sized by length times width, giving you an estimated floor space square footage. You can calculate your needs by square footage and/or the number of rooms you’ll be storing.

Keep in mind that units typically have a ceiling height of 8 feet; so a little space goes a long way.

Storage units are typically tall and you can safely stack a number of boxes and tubs, and turn couches and beds sideways to accommodate furniture. One normally thinks furniture has to rest in a unit in the same position it rests at home, but it doesn't. Sometimes that realization is an ‘ah-ha’ moment for many.
