Continue reading our self-storage unit size guide to help you decide what storage unit size would suit you best based on your storage needs.

What Is the Purpose of Self-Storage?

Self-storage can serve a different purpose for each individual or household and their situation. You could be an adventurous traveler looking for a temporary space for their belongings, a retired couple looking to downsize, or a millennial with a growing family moving into their first home. Self-storage can serve those in various situations and help them with their short-term or long-term storage needs. 

What Is Considered a Good Amount of Storage?

A good amount of storage space depends on what you plan on storing in your self-storage unit. For example, if you only have one set of winter tires, then a compact-sized unit would be considered a good amount of space. On the flip side, if you have two or three bedrooms worth of belongings, then a 5′ x 5′ will not be sufficient. In this case, you will require an upgrade to a larger self-storage unit to ensure that everything you plan on storing fits. You want to choose a self-storage unit that is able to fit all of your belongings comfortably without the fear of your belongings getting damaged while in storage. 

What Do You Plan On Storing?

The first question you want to ask yourself is: what am I planning on storing? Spend time compiling a list of belongings you plan on putting away in your storage unit. The list of belongings will ultimately give you an idea of what size storage unit you should consider and the ability to compare prices and features between different units. It will also help you avoid renting too large of a unit that could cost you hundreds of dollars more throughout the duration of your rental period than needed. Therefore, it is beneficial to take the time to estimate the right size storage unit for your belongings. In addition, you should try to keep track of items that are fragile or require to be in a climate-controlled facility so that you can keep that in mind when looking for a self-storage unit to rent.

What Are the Most Common Self-Storage Sizes?

When shopping around for a self-storage unit to rent, the following are the three most common self-storage categories: small, medium, and large. Typically most self-storage facilities have these three categories and have various sizes that fall within these categories. A few common storage unit sizes are 5′ x 5′, 10′ x 10′, and 10′ x 20′. However, it is best to research and see what storage unit sizes are available at each self-storage facility and at what price. Choose a self-storage facility that has a wide selection of self-storage unit sizes available for you to choose from. The reason is that you may be stuck deciding between a 10′ x 10′ and a 10′ x 20′; however, if a self-storage facility offers a 10′ x 15′, then that will work better for you, and perhaps it is cheaper too.

Organize Based on Frequency

Before placing your items in a storage unit, it is best to decide what items you need to access more often during the duration of your storage rental period. By determining that you can organize your belongings in a way that places those items in a position where you can easily access them if needed.

Organize Your Boxes

Determine how you plan on organizing your boxes, as it will help you stay organized by knowing where everything is located. How you decide to utilize the space in your unit is up to you. You could either stack or line up your boxes in your unit. However, a shelving unit can be helpful to avoid searching through several boxes or possibly heavy equipment. Keeping your storage unit organized will make your life a whole lot easier!

Calculating Storage Unit Size

A self-storage unit is commonly measured by feet allowing you to compare self-storage facilities and the sizes they offer without having to make the conversions. Let’s take a 5′ x 5′ sized unit for example. A 5′ x 5′ unit means that it is 5 feet in length and 5 feet in width totaling 25 square feet of space for storage. To give you a better idea of how much space this actually is you can fit 200 of our compact-sized XYZ Storage boxes in a 5′ x 5′ self-storage unit. By knowing how to calculate the square footage, you are better equipped to figure out which of your belongings the storage unit size you are considering can accommodate or typically fit.
