How to Estimate the storage unit size you need

How do I know the required storage dimensions?

Step 1: Make a list of everything you own or everything you intend to store

The first step in deciding the quantity of storage unit you require is determining how much you possess or intend to move. Pinpoint larger objects such as sofas, desks, and bookcases and count every one of your boxes/cartons. Make a note of everything. 

Suppose you wish to store the contents of a little bedroom, for instance. In that case, your inventory would most certainly comprise items like a bed and mattress, a refrigerator, a chair a bookcase,  a dresser or other furniture.

Step 2: Examine your storage options at home

After cataloguing every area, double-check that you have utilized all of your home’s storage space. The last thing you want is to commit to a storage unit only to discover that you could have saved money by storing some of your belongings in a partially empty closet or an unused section of your garage.

It is essential to double-check your options as the annual cost difference between a large and micro storage unit may be up to $800.

Step 3: Estimate your space requirement

Using the storage unit size chart above, estimate the space required to store your items. You’ll want to have the estimated space requirements in square feet or cubic feet as those measurements will determine what storage unit size will be rented out to you.

Step 4: Choose the most appropriate size storage unit for you

After taking all of your measurements, decide whether you need a small, medium, or large unit. The simplest method is to put your stuff in a pile and measure the pile’s length, width, and height, adding 1.5m to each measurement.

Comparing your dimensions to the table above can help you determine the best size for you.

Step 5: Do some Research

The next step is to conduct some research into storage facilities; once you have decided on whether you want a small, medium, or large storage space, you’ll need to obtain precise measurements from storage facilities. It would help if you also looked into as many storage facilities as possible to see who offers the best rate. In addition, to save money, make sure the storage unit you choose is large enough to store your belongings but not so large that there is a lot of unused space.

Types of Storage Units

There are various storage units, and selecting one to rent is mainly determined by the objects you wish to store. This section will serve as a guide to the different types of storage units available, so you can completely comprehend your options. The two major types of storage units are:

  • Indoor Storage
  • Outdoor Storage

Indoor Storage

Indoor storage units are found at a storage industry that is usually only accessible to authorized clients. A modern indoor storage facility would include large elevators and complimentary convenience carriages to enable moving your belongings in and out of the storage locker as seamless as possible.

Indoor storage facilities are better for storing miniature goods, expensive storage, or anything that requires temperature control because they are more secure against theft and temperature-related harm.

Outdoor storage

Outdoor storage units are the most common of all storage unit kinds. One of the main reasons for this is the ease of access to the facility since most owners can drive up to the storage unit and load and unload their belongings.

As a result, it is an outdoor space perfect for keeping larger items that are not temperature-sensitive such as household furniture items like a dining table set or bedroom furniture. It can also be used to store seasonal items such as seasonal decorations. Owners with drive-up access have convenient access to their belongings and can add or remove goods from the unit at any time.

Other storage units include vehicle storage units, wine storage units, and climate-controlled storage units. Vehicle storage units are often used to store recreational vehicles, boats, motorcycles, a U-pack trailer, commercial trailer,  rental trucks and other vehicles.
