How Big is a 40×40 Storage Unit?


40x40 storage unit

Before renting a self storage unit, it’s important to know roughly how much space you need. If you wind up buying a space that’s too large, then you are essentially paying for room that you don’t really need. It’s a waste of resources. But if you opt for a space that’s too small, it can result in frustration, especially if it means you have to upgrade to a new unit, then move all of your items once more.

As such, consulting with a storage unit size guide can always be advisable. Today, we want to take a closer look at the 40 x 40 unit size. Read on to find out roughly how much room you can expect from self storage units in this range, and to ascertain whether this is too much, not enough, or just the right square footage for you.

Sizing Up a 40 x 40 Storage Unit

When you rent a storage unit, you can often go as small as 5 x 5. And for those who are essentially seeking some extra space storage for holiday decor, lawncare items, tools, or overflow trinkets, this may be sufficient storage space.

The 40 x 40 unit, on the other hand, is at the other end of the spectrum. This is likely the largest unit you’re going to find, and in fact, some self storage facilities won’t offer storage units quite this big.

A storage unit of this size is really not even intended for self storage. It’s more likely to be used as a personal office or warehouse space. Indeed, when you rent a 40 x 40 business storage space, it’s likely to come with its own built-in restroom, sewer and water services, and a large service door. These large business suites are typically climate-controlled, as well, ensuring you can work in comfort, no matter the season.

In other words, if you’re just looking for a place to keep your lawn and garden tools, or to stash some unused furniture items, this business storage unit is probably more than you really need. But if you’re looking for a flexible and affordable space to operate a small business or to handle your warehousing and distribution needs, 40 x 40 may be just the right size!

Also note that, if you are looking for storage units that you can effectively use as workshops or creative spaces, this size of storage unit is likely to suit your needs.

Still have questions about whether a 40 x 40 unit will fit your needs? Here’s a rundown of some of the most common inquiries.

Can I use my 40 x 40 storage unit as a car garage or vehicle storage area?

A 40 x 40 unit will offer you ample storage room for several different vehicles, including cars, motorcycles, tractors, lawnmowers, or even an RV. However, it’s worth noting that there are other storage spaces that are more custom-tailored for vehicles, and may provide you with a more cost-effective avenue.

Can I use a 40 x 40 unit as a walk in closet?

A unit of this size is way, way, way bigger than a closet. You can certainly fit plenty of boxes and other items inside, but you’ll probably be better off investing in something a little cozier and more cost-effective. Again, this storage unit size is primarily intended for warehousing and business storage. Using it as a walk in closet is fine, but this level of space is unnecessary.

What are Some Alternative Storage Unit Sizes?

If you decide you don’t need one of these units, or don’t require a full business storage suite, you may want to consider some alternative storage units. Here are a few unit size options that may be better-suited to your needs.

10 x 10 Storage Unit

If you get one of these units, you’ll have enough storage for the contents of a single-bedroom apartment, which should be just fine if you’re essentially looking for walk in closet, or need to stack some boxes.

10 x 15 Storage Unit

This unit size will give you space enough for the contents of a two-bedroom apartment. By contrast, it will give you roughly enough space to have two business offices.

10 x 20 Storage Unit

One of these units will allow you to store the contents of a two-bedroom house, including the patio furniture, appliances, stacks upon stacks of boxes, etc.

10 x 25 Storage Unit

One of these units will give you enough space to store all the items in a standard three bedroom house, including patio furniture, washers, dryers, fridges, and plenty of boxes.

10 x 30 Storage Unit

Here’s another storage unit variant that will offer you more than enough room for the contents of a three bedroom home, including extra space storage for small vehicles, appliances, lots of boxes, etc.

Tips for Choosing the Right Unit Size

Measure Your Items in Advance

No, this doesn’t necessarily mean you need to take measurements of all your boxes and smaller items, but at least measure anything you have that is large, bulky, or oddly shaped. Just double check that everything you’re looking to store will fit into your chosen space.

Walk Through a Unit

This may sound like a no-brainer, but it really does make sense to tour some units before you decide on one. Actually stepping into a space can give you a much better understanding of how big it really is, and help you envision whether or not it will accommodate your boxes, furniture, and other items.

Plan How You’ll Use the Space

To maximize your space, we recommend being really intentional in the way you arrange your items. First and foremost, put everything into boxes if at all possible. Keeping up with too many loose items can be tough. Fill your boxes to the top, and stack them with wider/heavier boxes on the bottom and lighter boxes on top. Make sure you leave a walkway, allowing you to access boxes as you need them. Also, if there are items or boxes you think you’ll need to access more frequently, it’s probably best to put them toward the front.

Ask About Add-ons and Amenities

In addition to unit size, you will also want to consider perks and features, including climate control, sewage hook-ups, security, and more. Always inquire about these perks and amenities before you sign on for a unit… and also verify how much you’ll pay for them.

Follow the Rules of the Storage Facility

One of the most critical aspects of renting a storage unit is following all the rules and guidelines. Most of the time, these are pretty common-sense: Don’t store weapons or explosives, no pets or live animals, nothing flammable. Still, just to be on the safe side, request a copy of your storage facility’s rules, and read them carefully before you move your stuff into the unit.
