If you're looking for a small storage space at an affordable price, a 3x3 storage unit might be just what you're looking for. It's also excellent if you only need short-term storage between semesters, seasonally, or when reorganizing your closets.
In our guide, we'll break down what will fit in a 3x3 storage unit, who it's best for, and how it compares to other unit sizes. You'll be able to decide if it's the right storage unit for your storage needs!
How big is a 3x3 storage unit?
A 3x3 storage locker is compact, at only 9 square feet. It is typically the smallest size storage unit available at a storage facility. A 3x3 is comparable to a small hall closet or pantry.
Due to its compact size, it’s ideal for storing small, space-saving items. It’s also an excellent option for short-term storage, primarily due to its lower price point.
What items fit in a 3x3 storage unit?
Don’t be fooled by the 3x3! These little storage solutions can store items including:
6-10 small to medium-sized moving boxes
Plastic storage boxes and bins
Small furniture and decor, including petite end tables and nightstands, lamps, and artwork
Travel gear, such as suitcases and duffel bags
Seasonal clothing, especially if it’s packed in vacuum-sealed bags
Holiday decorations and seasonal items
Dorm accessories and bedding
Small sports equipment and fitness gear, such as yoga mats and tennis rackets
Musical instruments - great for during summer break!
A 3x3 can be the right storage unit for seasonal decor, student storage, and even business storage. A small storage unit is excellent for storing boxes of files, office supplies, and extra printers.
What cannot fit in 3x3 storage?
It goes without saying that many items cannot fit in a 3x3 storage unit (which is OK! These storage lockers aren't meant for those things anyway!). You'll want to consider a larger storage unit if you plan to store:
- Most furniture items, including bedroom sets, a dining room set, or living room furniture, including couches
- Outdoor equipment, such as a lawnmower
- Household appliances, such as a washer or refrigerator
- Mattress sets
- Office desks, chairs, and bulky office printers
You'll also want to choose a large storage unit if you're searching for vehicle storage! (We recommend checking out a 10x20 storage unit.)
Is a 3x3 storage locker ideal for wine storage?
Yes! 3x3 climate-controlled storage is perfect for your wine collection.
How many bottles will fit in a 3x3 storage unit? It depends on how you're storing your wine:
- Using a standard wine rack: These racks usually hold 40-50 bottles of wine apiece. You may be able to fit 3-4 wine racks in your 3x3 storage unit, so you can comfortably store up to 200 bottles of wine.
- Using boxes or crates: You should be able to fit between 8-12 cases of wine in your 3x3, which equates to 96 to 144 bottles!
You'll always want to opt for climate control when selecting a wine unit. Wine requires a stable environment, maintained at around 55°F with consistent humidity. Select Storage Star locations offer small storage lockers designed explicitly for small wine collections - perfect for personal use or seasonal overflow.

Who should use a 3x3 storage unit?
A 3x3 storage unit is ideal for anyone who's looking for just a little extra space at a low cost. 3x3s typically are a cheap storage unit option! Here are some people who will definitely benefit from these compact lockers:
- Students: These units are great for student storage. They'll hold your dorm essentials, including bedding, small appliances, and extra books. Consider renting one between semesters, when studying abroad, or starting a summer internship.
- Apartment Renters: When you just need an extra closet! Perfect for those living in small spaces who need more space for boxes, decor, or seasonal items.
- Travelers: If you frequently have wanderlust and are booking vacations, you may need somewhere to house all your travel gear! Think luggage, duffel bags, book bags, and other travel packing supplies.
- Wine Collectors: We've already covered it, but wine lovers can use a climate-controlled 3x3 to securely store up to 200 bottles of wine.
- Executor of an Estate: When someone has passed, you may need secure short-term storage for a variety of things - papers pertaining to wills or real estate, valuables the deceased left, or personal belongings you're keeping to distribute to family members.
We also recommend a 3x3 for small business owners with file overflow and holiday enthusiasts with too many decorations.

What size boxes should I use in a 3x3?
Before you buy your supplies, here are some recommendations:
- Uniform, stackable boxes
- Small boxes that are 12x12x12"
- Medium boxes that are no larger than 18x18x18"
- Clear bins to easily identify contents
- Vacuum-sealed bags for clothing and bedding - this will save space, and they're stackable
With limited floor space, you can use the unit's height to your advantage. Vertical organization is key, so make sure to stack (and stack boxes efficiently!).
