The Ultimate Storage Unit Size Guide

Storage units are a great place to keep your things but figuring out what size you need can be difficult. In this post, we want to help you answer that ever important question: “What size storage unit do I need?”
  • Small units make for a useful extra space if you don’t have enough storage space in your home.
  • Medium-sized units are best for storing larger items like a king size bed and family room furniture.
  • The largest storage units are perfect for storing vehicles or several pieces of furniture.
If you’re still confused, don’t worry. Below, we’ll explain everything you need to know about storage unit size, how to choose a storage unit, and pricing.  

Storage Unit Size Breakdown (and What Fits)

If you are trying to determine how much storage space you need, the first thing you’ll probably think about is how much each unit can hold. Below, we break down the most common storage unit sizes for you.
  • 5ft x 5ft (25 Square Feet)

    A 25sq ft sized unit is considered to be equivalent to the size of a large closet. It’s good for storing things like seasonal items, boxes, personal items, or a twin sized bed. Think of it like an extra space to store things you don’t use frequently. If you are planning a big move and need a lot of space, this isn’t the unit for you.
  • 5ft x 10ft (50 Square Feet)

    This unit size is more like a walk-in closet. It can hold one or two pieces of large furniture or a few pieces of smaller furniture. Plus, quite a few boxes (between 10 and 15). This is a good size for someone looking to store the contents of an entertainment center or single bedroom.
  • 10ft x 15ft (150 Square Feet)

    A 150sq ft storage unit can store the contents of a two bedroom house or apartment. This means two mattresses, two sets of bedroom furniture, and all the other furniture in the house like appliances, tables, and living room furniture. Generally speaking, it can store everything that could fit into a 1000 square foot living space.
  • 10ft x 30ft (300 Square Feet)

    As the biggest storage unit on our list, a 300sq ft storage space is for people who need to store a lot. It’s about the size of a two-car garage and can fit all the contents of a 3-4 bedroom home. That means up to 4 full bedrooms, plus appliances, home decor, and other furniture. It’s also a great option for vehicle storage.

3 Tips to Choose the Right Storage Size

Maybe after reading that you’re thinking: “Yeah, okay. But how much storage space do I need?” Just because you know what each unit size can supposedly fit, it can still be hard to determine which unit size will fit your specific storage needs. In this section, we will go further into detail on how to decide what storage unit to use and how you can better plan to store.

  1. Make a List

    The first thing you need to do is think about what items you want to put in your storage unit. Then, write down every single thing. Check it multiple times to make sure that you don’t forget anything. Making a list will help you realize how much, or how little, you actually need to store. Follow our packing guide to properly pack your belongings before putting in storage.
  2. Think About Shape

    The next thing you need to do is think about the actual shape of the items. Boxes are easy to store and stack (depending on how heavy they are). However, a car, a bed frame, or a table with a funky shape can be a bit more difficult. You need to think about how you can puzzle together every item so that everything will fit.
  3. Go See the Unit

    If you can, try visiting a storage unit that has the same dimensions as the one that you are interested in. This will make it a lot easier to actually visualize how you will be able to fit your items into the unit. It can also help you decide if that size unit is realistic for you. If you can’t go visit a unit, consider using a size estimator online.


The last thing you need to do is figure out how much everything will cost. If you are interested in learning more about the prices of our storage units and getting a quote, please visit our storage pricing page.
