Whether you’re downsizing, relocating, or just need some extra space, storage units provide a flexible solution to your storage needs. However, it can be difficult to determine the right storage unit size for your items. To help you make an informed decision, we scoured the websites of top moving companies and self-storage facilities to bring you this detailed guide to storage unit sizes.
The most common storage unit sizes range from 5-by-5 feet to 10-by-30 feet (25 to 400 square feet) with many variations in between. Small storage units are perfect for storing seasonal decorations and sports equipment long term, while medium and large units work well for short-term storage during a move. The largest sizes also work well for storing business inventory or commercial equipment.
Note: The average costs listed below were calculated using quotes we pulled from publicstorage.com and storage.com. We looked up the price of each storage unit size in five different cities (New York, Los Angeles, Las Vegas, Houston, and Orlando) and averaged them together. However, not all sizes were available in every city, and prices could be significantly lower in more rural areas than in these large metropolitan areas.
Christmas tree, boxes of decorations, and holiday yard decor
$74.40 per month
A 5-by-5-foot storage unit, also known as a storage locker, is one of the smallest units available. It’s perfect for storing sports equipment and seasonal items, such as holiday decorations, camping gear, or winter clothing. About the size of a closet, a 5-by-5-foot unit can fit a few boxes and small furniture items, such as a dresser. This makes it a great solution for college students who need to store dorm furniture and decor between semesters.
Queen-size mattress, sofa, chair, bike, and clothes
$146.40 per month
A 5-by-10-foot storage unit is the size of a large walk-in closet or a small room—large enough for the contents of a single bedroom or a small studio apartment. It’s the perfect size for storing medium-size appliances, such as a washer and dryer, or larger sports equipment, such as bicycles or kayaks. A 5-by-10-foot unit can also be used for business storage. It can easily hold 100 banker boxes or 30 medium-size moving boxes with room for an aisle down the middle.
Kitchen appliances,

, and boxed kitchenware
$203.20 per month
A 10-by-10-foot storage unit is ideal for storing the contents of a one-bedroom apartment, including large furniture items and a few dozen boxes. It can also serve as a garage for smaller vehicles, such as motorcycles or ATVs, if you need to free up some garage space. This unit is a popular choice for those who are moving or downsizing and need a temporary storage solution. It’s a little smaller than an average 10-by-12-foot bedroom and about half the size of a standard one-car garage.
Everything in your bedroom, a living room set, and a motorcycle
$285.60 per month
A 10-by-15-foot storage unit is large enough to hold the contents of a small house or two-bedroom apartment. Slightly smaller than a standard one-car garage, it’s ideal for storing a motorcycle plus an assortment of tools and recreational gear. You could also use this size unit to temporarily store the contents of your downstairs living area during a remodel. It can fit a king-size bed, a sectional couch, a refrigerator, and several large boxes.
One car, a bookshelf, and a few boxes
$313.40 per month
A 10-by-20-foot storage unit is roughly the size of a one-car garage and the smallest size that is recommended for vehicle storage. If you use it as a garage, you should be able to fit a small car or boat plus a few boxes or a shelving unit in the back. Without a vehicle taking up space, you can fit 80 to 100 moving boxes or the contents of a multi-bedroom house. Alternatively, you could use it to store items that you don’t use year-round, such as lawn mowers, kayaks, yard tools, and patio furniture.
A large vehicle, tools, and
sports equipment
$394.40 per month
A 10-by-25-foot storage unit is a spacious option for those who need to store an antique vehicle or the contents of a four-bedroom house. It is slightly larger than a one-car garage with plenty of space for a boat, a pair of water skis, or ATVs. This unit is ideal for those who need to store their belongings during military deployment or a gap between their move-out and move-in dates. It can also be used as extra warehouse space for a small business.
One car, a mattress, a few small pieces of furniture, and some boxes
$574 per month
A 10×30 storage unit is the largest standard storage unit size available. It can hold the contents of a fully furnished four-bedroom home plus a standard garage, giving you enough room to store your vehicle and belongings between home closings. Alternatively, you could use it to store commercial equipment, several large appliances, business inventory, or a camper or RV. Few items will be too large to fit in 300 square feet of space.
Two cars, a few pieces of furniture, and several boxes
$695.33 per month
A 20-by-20-foot storage unit is the size of a cozy 400-square-foot studio apartment or a two-car garage. This unit size has 100 more square feet and a wider entrance than a 10-by-30-foot unit, making it the perfect option for storing large equipment or multiple vehicles. It also works great as a small warehouse for business inventory or equipment. However, large storage units this size are relatively uncommon. For instance, U-Haul and CubeSmart only list units up to 10-by-30 feet.
Choosing the right size self-storage unit can be challenging, but with careful planning and measuring, you can find the perfect unit for your needs. Many storage facilities and long-distance moving companies have storage unit size guides on their websites to help. In most cases, you can easily switch to a different size if you outgrow your original unit or find it has more storage space than you need.
For those with minimal storage needs, a small 5-by-5-foot storage unit is ideal, while those looking to store a vehicle or business inventory may need a larger 10-by-30 or 20-by-20-foot unit. If you need to store the contents of multiple rooms during a remodel or move, consider a 10-by-10 or 10-by-20-foot unit. As you narrow down your options, factor in the amount of space you need, your budget, and the value of the items you’re storing.
Here are the best ways to organize a storage unit:Maximize vertical space with shelving.Use stackable storage bins.Label all boxes and bins clearly.Create an aisle down the center for easy access.Place frequently used items near the front.Protect larger items with furniture covers.Keep seasonal items toward the back.Stack lighter boxes on top of heavier ones.
The most popular storage unit size is 10-by-10 feet, which is about half the size of a spare bedroom. This size is commonly used for short-term storage during an apartment move, to free up space in the garage, or to store items during a room remodel.
Whether storage units are worth it depends on your individual circumstances and needs. For many people, storage units provide a convenient and safe place to store items that they may not have space for at home—whether they are moving, downsizing, or just looking for extra storage. If you have items you don’t want to part with or that you only need to access occasionally, a storage unit may be a good option.

10 Things That Can & Can’t Be Stored In A Self-Storage Unit
If you’re reading this article, we’re guessing it’s because you did an Internet search for what you can and can’t store in a storage unit. It’s a fair question to ask because just like most things in life, there are rules and exceptions — plus usually some grey areas in between.
Whatever your reasons for seeking a self-storage unit, we’re guessing you rank somewhere on the scale between info-savvy and street-smart. So, you probably don’t really need to be told that you can’t store pets, stolen items, or things likely to explode in self-storage. Right? (The only good answer here is, “Correct!”)
As your Internet search probably proved, there are plenty of lists about what you can and can’t store in a self-storage unit — and most of them are similar, straightforward and appeal to good, old-fashioned common sense.
Those lists are helpful but we want to offer a different spin on things: What do those “do’s and don’ts” storage tip lists really mean to you, just a regular person looking to protect your stuff and avoid any inadvertent storage slip-ups? Well, let’s find out!
We’ll focus on 10 broad categories of items that you can and shouldn’t store, but we’ll talk about what this means in real-life terms — plus provide some bonus tips based on what we’ve learned over the years as self-storage experts.
Think of this as your common-sense self-storage guide.
5 Things You CAN’T Store in Self-Storage
Let’s start with what you can’t store, because frankly, that list is more interesting:
Hazardous Materials
These lists can be long but here’s the short rule: If they can catch fire or explode, then they’re a no-go. This includes gasoline, propane, oil, grease, chemicals, cleaners, aerosols, and paint.
What This Means In Real Life:
Are you storing art supplies?
Then this means that you can’t store mineral spirits or paint thinner.
Are you packing up bathroom or kitchen items?
Best to leave aerosol sprays (don’t forget hairspray and cooking spray) and nail polish remover out.
Need a place for your gardening supplies?
You’ll need to ditch the fertilizer and weed killer.
Do you need to store lawn equipment?
Make sure it’s drained of oil and gasoline before storing.
BONUS TIPS:
If you’re storing non-hazardous liquids like non-toxic paint or beauty supplies, make sure to store them in airtight containers or bags so that if they do spill or leak, they are contained.
If you’re unclear about how to dispose of any unwanted hazardous materials, check with your local waste management agency. You can find more helpful information

Living Animals, People, and Plants
We’ve heard some crazy stories about people who took the concept of self-storage literally, using their unit for them or their pets to live in. We probably don’t need to tell you why this is a really bad idea, so just don’t do it. Same goes for plants. Not only will they die, but their soil attracts moisture, which can lead to mold, mildew, and potential pests.
What This Means In Real Life:
With competitive price and timely delivery, EVERGREAT sincerely hope to be your supplier and partner.
Do you like reptiles or small caged animals like hamsters?
It’s hard for most of us to envision keeping a more mobile, vocal pet like a dog or cat in a storage unit, but this also includes smaller animals in tanks and cages. Most animals in those categories need regular care and feeding, a light source, and fresh air, so please find a more safe and humane place for these animals. We don’t know who needs to hear this but this means that if you’re a week between apartments, do not bring your pet snake in its tank to your storage unit because it’s “only for a few days.” Just. No.
BONUS TIP: If you follow our advice and dump plants from their containers before storing them, make sure to clean and dry the containers very well. Even small amounts of soil, dirt, or water can breed moisture and attract unwanted pests.
Perishables
If food needs to be stored in a refrigerator, it’s perishable. So, meat, dairy, and produce shouldn’t be stored, not even in a short-term cooler. Of course, non-perishable foods can be fine to store, especially if they’re kept in airtight containers.
What This Means In Real Life:
Do you need to store dry goods?
We’ve seen a rise in people interested in storing non-perishable food (freeze-dried, dehydrated) for emergency planning. While these foods should be fine, please remember there are similar foods that are not okay to store: Rice and other grains, powdered milk, boxed foods, flour, and pet foods can turn rancid, smell, and attract rodents and pests. And, if you must store dry goods, be sure to do so in glass or very thick plastic containers. Rodents can smell (and gnaw) through thin and even thicker “cereal style” plastic containers you may think are thick enough.
BONUS TIP: If you’re storing canned foods (either tinned or in glass canning jars), then make sure that you periodically check the expiration dates and for any damaged containers that could introduce moisture or bacteria. It’s also helpful to store any non-perishable, canned foods on shelves.
Weapons, Explosives, Stolen Items
We’re only including this here to cover all the bases and provide an exhaustive list of what you can’t store, but we’ll keep this short and minus a bonus tip: If it can purposely hurt someone or isn’t legal, then it doesn’t belong in a storage unit. The end.
What This Means In Real Life:
Are you storing summertime or seasonal items?
You’ll want to make sure that there are no small fireworks (think poppers or sparklers) in your July 4th or New Year’s Eve bins.
Are you storing a vehicle?
Just remember that any vehicle you store, whether that’s a boat, RV, trailer, motorcycle, car, or truck, must be fully registered, insured, and in operable condition. And, it must be registered in the name of the person renting the storage unit. (And don’t forget to drain the oil and ful from it beforehand.)
Scented or Wet Items
So, these aren’t items you typically find on a “you can’t store this” list, but trust us when we tell you that you don’t want to make the mistake of storing items that are wet (even damp) or have strong scents. We like explaining this category to people because it’s often overlooked.
What This Means In Real Life:
Here’s a short list of scented items you shouldn’t store in a self-storage unit:
Incense, strong soaps and lotions, candles, oils, perfumes, and even strong spices.
BONUS TIPS:
Follow our “high and dry” rule by using pallets and shelves to keep things off the floor, where moisture can collect.
Add
moisture absorption packets
in the corners of your storage unit and throughout your storage bins, furniture drawers, etc.
If you are moving on a wet, rainy day, then you’ll want to make sure that you bring a few extra towels to dry off items that get wet — and then take those towels home with you. Don’t just toss them in the corner of your storage unit! Wet = Bad.
5 Things You CAN Store in Self-Storage
Seasonal Items
Seasonal items and self-storage go together like peanut butter and jelly: they’re made for each other. From Christmas decor to camping gear, there will always be things that we only need access to at certain times of year. And, a storage unit is a great place to store it all on a rotating basis.
What This Means In Real Life:
Before you store electronic holiday decorations, make sure they’re all still
in working order
.
If something isn’t working, the best time to buy a replacement is right after the holidays when decorations are usually reduced by 50% or more.
BONUS TIP: Don’t forget that seasonal items include wardrobe and winter gear. A storage unit is a great place to store your seasonal swap-outs, and even better if it’s climate-controlled.
Household Goods
As you might imagine, this category contains the most stored items found in self-storage units: furniture, toys, kitchen and bathroom items, books, clothes, and more. This category can also include keepsakes, collectibles, and antiques. The best choice you can make for these items is to place them in climate-controlled storage, where both temperature and humidity are regulated to keep your treasured pieces in good condition.
What This Means In Real Life:
Whether you’re
packing up your kitchen
for a short- or long-term move, pack a “starter kit” box of items you’ll need right away: A few plates, bowls, cups, glasses, and basic kitchen tools. Don’t forget to throw in some paper towels and Ziploc bags. They’ll come in handy!
BONUS TIP: It’s tempting to wrap a lot of items in newspaper. Instead, try using heavier grades of paper, or kraft paper (more elastic and difficult to tear), for wrapping items. Newspaper doesn’t offer this level of protection. Check out more of our tips for packing fragile items.
Business Items
We’re seeing more businesses rely on self-storage for moving and offsite storage. Not only is the price per square foot better than anything you’ll pay for a warehouse or additional office space, but you can also write off business storage as an expense. And, self-storage is perfect for small business owners like realtors, caterers, home stagers and organizers, and more.
What This Means In Real Life
If you’re storing
financial
or sensitive documents, keep files you need more access to in filing cabinets near the front of your storage unit. Longer-term documents that can’t be discarded for record-keeping purposes can be stored in sturdy filing boxes further back in your unit. Above all else, don’t forget to clearly label the contents for easy reference.
BONUS TIP: If you’re using your self-storage unit to house inventory that you ship or prepare for customers, consider setting up a shipping station with everything you need to prepare your mailings.
Electronics
As much as we rely on electronics in our lives, sometimes items like TVs, stereo systems and speakers, computers and printers just need to be stored. Given that these can be costly investments, it pays to make sure you have the right supplies to pack them properly. We also urge you to consider storing these in a climate-controlled storage unit for ultimate protection.
What This Means In Real Life:
Before you store your electronics, make sure to remove CDs, DVDs, ink jet cartridges and batteries — all items that can get stuck or cause corrosion over time.
BONUS TIP: Detach the wires and other accessories that go along with your electronics (keyboard, mouse, speakers). Bundle the wires together. Label each wire with a specific color sticker that coincides with its equipment. Keep electronic components together in a plastic bag attached to the electronic item.
Appliances
Appliances can be stored as long as they are cleaned and dried prior to storage and are never left plugged in while being stored. This includes refrigerators, stoves, microwaves, washers, dryers, and freezers. Smaller appliances like toasters, coffee makers, and vacuums are also fine, as long as they are wiped clean of crumbs and dried-on drips beforehand.
What This Means In Real Life:
Keep appliances upright against the wall; leave doors slightly open to allow air to pass through the appliance, avoiding musty smells.
BONUS TIP: Wrap up appliance cords, and place cleaned attachments inside of the appliances.
