How to Pick the Right Storage Unit Size
Finding a self storage unit near you is the first step of the process. The next step is to figure out the right storage unit size that best fits your needs. If you’re unsure of which type of unit to reserve, our storage unit size guide can help. In this video, we break down the most common storage unit sizes and the types of items that can fit in each one as well as the keys to determining what size storage unit you need. Key points include:
Determine what you want to put in storage:
Take stock of how much stuff you have and the number of items you’ll need to store. Count your boxes and compile an inventory of items. Evaluate the size, shape, and quantity of the items you really need to put in storage and use that to estimate how big of a storage unit you need. Make a note of any items that are larger than normal or oddly shaped. Note anything that would require climate-controlled storage units, too.
Plan to maximize the space:
Refer back to your inventory. Will you store mostly boxes? Are the items easily stackable? Do large furniture items need to be included? Remember that most storage units have a height of 8 feet, so when you think about how to organize your stuff, take advantage of vertical space and stack upward to the sky.
Calculate the amount of space you need:
If you're still in doubt, gather all of your stuff into one place and actually measure it with a tape measure. That will help you calculate which storage unit size you need so you don’t end up with the wrong size.
