“What Would Fit?” Storage Unit Sizing Guide

by | Apr 28, 2025

When it comes to renting a storage unit, one of the most frequent questions people ask is, “What size storage unit do I need?” The answer often depends on the amount of stuff you’re storing, as well as the layout of your items. While it may seem like a daunting task to figure out the right sizing, we’re here to help you understand the options and make the process as simple as possible. Let’s dive into our storage unit sizing guide to help you choose the perfect fit for your belongings.

Step 1: Understand Your Needs

Moving Out for the First Time Checklist

Before you start searching for the right storage unit, it’s important to assess what you’ll be storing. Are you storing seasonal items like holiday decorations and clothing? Or do you need to store larger items like furniture and appliances? Understanding the scope of your needs will allow you to choose the correct unit sizing, saving both space and money.

For example, if you’re storing just a few boxes and a couple of small items, a 5×5 unit—about the size of a small closet—might be just right. However, if you’re storing larger pieces like furniture, you may need something bigger, such as a 10×10 unit.

Step 2: Determine the Sizing You Need

Now that you have a better understanding of what you need to store, let’s take a look at some common storage unit sizes and what they can typically hold:

  • 5×5 Unit: This is the smallest unit available, ideal for a few boxes, small furniture, or personal items. You can easily fit items such as a twin mattress, a couple of chairs, or a few boxes of books or clothes

  • 5×10 Unit: A step up from the 5×5, this unit is perfect for storing more items. It can accommodate items like a full-size mattress, a small couch, or several boxes. It’s also a great choice for someone who needs to store the contents of a small one-bedroom apartment

  • 10×10 Unit: This unit can fit the contents of a one-bedroom apartment, including furniture, boxes, and appliances. A 10×10 unit is also useful for storing seasonal equipment, like bicycles, camping gear, or holiday decorations

  • 10×15 Unit: If you need to store larger items or are moving a two-bedroom apartment’s worth of items, a 10×15 unit provides plenty of space. You can fit larger furniture such as a sectional sofa, a queen-size bed, and multiple boxes

  • 10×20 Unit: Ideal for storing the contents of a larger home, this unit can hold items like large furniture, multiple appliances, and boxes from a two- to three-bedroom house. It’s also a great option for storing vehicles such as motorcycles or small cars

  • 10×30 Unit: If you’re moving out of a large home or need to store business inventory, this unit is your best bet. A 10×30 unit provides ample space for everything from multiple bedrooms of furniture to larger items like refrigerators, washers, and dryers

Step 3: Climate Control: Do You Need It?

Moreover, when you’re choosing the right unit sizing, consider whether you need climate control. If you’re storing temperature-sensitive items like electronics, antiques, or wooden furniture, a climate-controlled unit can provide the protection your belongings need from extreme temperatures and humidity. Climate-controlled units are especially beneficial for long-term storage, as they help prevent damage from moisture and temperature fluctuations.

While climate control typically costs a little more, it’s worth the investment for items that are sensitive to environmental conditions. However, if you’re storing more durable items, such as tools or outdoor equipment, a regular unit might suffice.

Step 4: Visualize Your Items in the Space

It can sometimes be difficult to imagine how your items will fit into the space of a storage unit. However, one effective way to visualize this is to lay your items out in your current space before making a decision. For instance, if you plan to store furniture, see how much room it would take up in your living room or garage. This will give you a clearer idea of what sizing unit you’ll need.

Another option is to use online storage calculators, many of which are provided by self-storage companies. These tools allow you to input your items and get recommendations on the appropriate unit sizing, taking the guesswork out of the process.

Step 5: Reserve Your Storage Unit

Once you’ve figured out the right sizing for your needs, the next step is to reserve your unit. Many self-storage facilities offer flexible rental terms, so you don’t have to commit to a long-term lease if you don’t need the space for an extended period. Moreover, by reserving ahead of time, you ensure you get the unit size you need at the right time.

Remember, it’s always better to rent a unit that’s a bit too big than to struggle with cramming everything into a unit that’s too small. This way, you’ll have enough room to store your items properly, avoiding unnecessary stress.
