5x5 Storage Unit: Pricing, Availability, and What Fits Inside
This guide covers real pricing data, what actually fits inside, how to compare facilities, and how to decide whether a 5x5 is the right size for your needs.
How Big Is a 5x5 Storage Unit, Really?
A 5x5 storage unit measures 5 feet wide by 5 feet deep. Most units have ceilings between 8 and 10 feet, which means your actual usable volume ranges from 200 to 250 cubic feet. That matters more than the floor dimensions alone because stacking is how you maximize a small unit.
To put it in perspective:
| Comparison | Dimensions | Square Footage |
|---|---|---|
| 5x5 storage unit | 5 ft x 5 ft | 25 sq ft |
| Average walk-in closet | 5 ft x 6 ft | 30 sq ft |
| Half bathroom | 5 ft x 8 ft | 40 sq ft |
| King-size bed footprint | 6.3 ft x 6.7 ft | 42 sq ft |
So no, a 5x5 storage unit is not quite the same size as a closet, but it is close. The key difference is ceiling height. Most closets top out at 8 feet, while many storage units reach 9 or 10 feet, giving you a surprising amount of vertical room to work with.
For anyone unfamiliar with self-storage dimensions, the U.S. Small Business Administration's guide to commercial leasing offers helpful context on how square footage translates to usable space in commercial settings.
What Fits in a 5x5 Storage Unit?
This is the question nearly everyone asks first, and the answer depends on how well you pack. A 5x5 unit comfortably holds the contents of one large closet or a small room's worth of belongings.
Here is what typically fits:
Furniture and large items (pick 2 to 3):
- A twin or full-size mattress set (stored upright against the wall)
- A small dresser or nightstand
- A compact bookshelf
- A bicycle
- A small desk or folding table
Boxes and miscellaneous (15 to 20 medium boxes when stacked):
- Seasonal clothing and coats
- Holiday decorations
- Sporting equipment
- Small electronics and documents
- Kitchen appliances you are not currently using
Pro tip: If you are storing a mattress in a 5x5 unit, invest $15 to $25 in a mattress storage bag. Standing the mattress on its side against the back wall frees up the remaining floor space for boxes and smaller items. A queen or king mattress will not fit well in a 5x5; you will want to step up to a 5x10.
Can I Store a Mattress in a 5x5 Unit?
Yes, but only a twin or full-size mattress. Stand it vertically against the back or side wall and secure it so it does not lean into your other items. A queen mattress at 60 inches wide technically fits the 60-inch wall, but you lose nearly all remaining space. If a mattress is your primary item, a 5x5 works. If you need to store a mattress plus other belongings, consider the next size up.
How Many Boxes Fit in a 5x5 Storage Unit?
With no furniture, you can stack approximately 20 to 25 medium moving boxes (18 x 18 x 16 inches) in a 5x5 unit, assuming you stack to about 6 feet high. Stacking higher is possible but increases the risk of crushing lower boxes. Label everything on two sides so you can identify contents without moving the entire stack.
Is a 5x5 Storage Unit Big Enough for a Bedroom?
Not a full bedroom, no. A 5x5 unit will hold pieces from a bedroom, but not the full contents of an average-sized room. If you are clearing out a child's bedroom, a dorm room, or a very minimal space, it can work. For a typical adult bedroom with a full furniture set, you are looking at a 10x10 unit.
Is a 5x5 Storage Unit Enough for an Apartment?
It depends entirely on the apartment size and how much you are storing. For a studio apartment where you are keeping most of your furniture and just need to store off-season clothes, documents, and a few boxes, a 5x5 is ideal. If you are putting an entire studio's contents into storage during a move or renovation, you will need at least a 5x10 or 10x10.
| Storage Scenario | Recommended Unit Size |
|---|---|
| Seasonal items and boxes only | 5x5 |
| Studio apartment overflow | 5x5 |
| Full dorm room contents | 5x5 or 5x10 |
| One-bedroom apartment (full contents) | 10x10 |
| Two-bedroom apartment (full contents) | 10x15 or 10x20 |

How Much Does a 5x5 Storage Unit Cost Per Month?
National averages for a standard 5x5 unit range from $40 to $65 per month. Climate-controlled units run $50 to $85 per month. These numbers shift significantly by region.
| Metro Area | Standard 5x5 (Monthly) | Climate-Controlled 5x5 (Monthly) |
|---|---|---|
| Dallas-Fort Worth, TX | $35 - $55 | $50 - $70 |
| New York City, NY | $70 - $120 | $90 - $150 |
| Phoenix, AZ | $30 - $50 | $45 - $65 |
| Chicago, IL | $45 - $65 | $55 - $80 |
| National Average | $40 - $65 | $50 - $85 |
Several factors influence what you will actually pay:
Location within the metro area. A facility 15 minutes outside the city center can cost 20% to 40% less than one downtown. The trade-off is convenience.
Promotions and move-in specials. Most facilities offer first-month-free or first-month-half-off deals. Always ask. If a facility does not mention a deal, request one directly. The industry standard is to offer some form of introductory discount.
Lease flexibility. Month-to-month leases typically cost more than longer commitments. If you know you need storage for six months or more, ask about rate locks.
Insurance or tenant protection. Some facilities require you to carry a protection plan. At Good Boy Storage, our tenant protection plans are straightforward and affordable, giving you coverage without inflated add-on costs.
The U.S. Census Bureau's annual construction survey data shows that self-storage construction has increased steadily over the past decade, which has generally helped keep pricing competitive in most markets.
Where Can I Rent an Affordable 5x5 Storage Unit Near Me?
Start by narrowing your search to facilities within a 10 to 15 minute drive from your home or workplace. Storage you cannot easily access loses most of its practical value.
When evaluating facilities, compare these specifics:
Access hours. Some facilities offer 24/7 access; others restrict entry to business hours. If you work non-traditional hours, this matters.
Security features. Look for individually alarmed units, gated access with unique entry codes, and on-site camera surveillance. Indoor units with hallway access tend to offer better security than outdoor drive-up units.
Online booking and move-in process. The ability to reserve and sign your lease online saves time. Many modern facilities allow fully contactless move-in.
Month-to-month flexibility. Avoid long-term contracts unless they come with a meaningful discount. Your storage needs may change faster than you expect.

Which Storage Companies Offer Secure 5x5 Units with Flexible Month-to-Month Leases?
Most national and regional operators offer month-to-month terms, but security standards vary widely. When comparing companies, ask specifically about:
- Individual door alarms on each unit (not just cameras in common areas)
- Gated perimeter access with personalized entry codes
- Whether the facility is staffed on-site or managed remotely
- Lighting quality in hallways and around the property at night
What to watch for: Some facilities advertise "24-hour surveillance" but only have cameras at the entrance and exit gates. True security means coverage of individual hallways and unit doors.
At Good Boy Storage, every location features gated access, on-site cameras, and well-lit facilities designed for peace of mind. Learn more about our approach and what sets our facilities apart.
How Do I Compare Prices and Features for 5x5 Storage Units Before Reserving One?
The most efficient approach is to check three to five facilities within your target area and evaluate them side by side. Here is a framework:
| Feature | Facility A | Facility B | Facility C |
|---|---|---|---|
| Monthly rate (5x5) | $__ | $__ | $__ |
| Climate controlled? | Yes/No | Yes/No | Yes/No |
| Move-in special | $__ | $__ | $__ |
| Access hours | __ | __ | __ |
| Security (cameras, gate, alarms) | __ | __ | __ |
| Online booking available? | Yes/No | Yes/No | Yes/No |
| Month-to-month lease? | Yes/No | Yes/No | Yes/No |
| Tenant protection cost | $__ | $__ | $__ |
| Drive time from home | __ min | __ min | __ min |
Print this out or make a spreadsheet. The lowest sticker price is not always the best value once you factor in required insurance, limited access hours, or a longer drive.
Is Climate Control Necessary for a 5x5 Unit?
It depends on what you are storing and where you live.
Climate control is worth it for:
- Electronics, including laptops, tablets, and gaming consoles
- Important documents, photographs, and paperwork
- Wooden furniture that can warp in humidity
- Vinyl records, musical instruments, and artwork
- Leather goods and delicate fabrics
You can likely skip climate control for:
- Metal tools and hardware
- Plastic bins of holiday decorations
- Camping and outdoor gear
- Sturdy cardboard boxes of non-sensitive items
In southern and coastal states where summer temperatures regularly exceed 90 degrees and humidity stays high, climate control protects against mold, mildew, and heat damage. In arid western climates, standard units hold up well for most items.
The National Archives and Records Administration (NARA) recommends storing important documents at temperatures below 75 degrees Fahrenheit with relative humidity between 30% and 40% for long-term preservation. If you are storing tax records, legal documents, or personal archives, climate control aligns with these guidelines.
Can I Rent a Climate-Controlled 5x5 Unit for Electronics and Important Documents?
Yes, and it is one of the smartest uses of a 5x5 unit. A climate-controlled 5x5 is large enough to hold several file boxes of important documents alongside small electronics, and the premium over a standard unit is typically only $10 to $20 per month. For protecting items that are difficult or impossible to replace, that cost is minimal.
When storing electronics, keep them in their original packaging if possible, or wrap them in anti-static materials. Avoid plastic bags, which trap moisture. Documents should go in sealed plastic bins rather than cardboard, which absorbs humidity even in climate-controlled environments.
What Should I Look for When Booking a 5x5 Unit for Seasonal Decorations and Clothing?
Seasonal storage is one of the most common uses for a 5x5 unit, and a few precautions go a long way:
For clothing:
- Use vacuum-sealed bags to maximize space and protect against dust and pests
- Avoid cardboard boxes for long-term clothing storage; use clear plastic bins instead
- Add cedar blocks or silica gel packets to absorb moisture
- Never store clothing that has not been freshly laundered; residual oils attract pests
For holiday decorations:
- Wrap fragile ornaments individually in tissue paper or bubble wrap
- Use compartmentalized ornament storage boxes rather than loose packing
- Store artificial trees in their original boxes or in tree storage bags
- Keep lights wound on cardboard to prevent tangling
A 5x5 unit can hold 6 to 8 large plastic bins of seasonal items with room to spare. If you rotate decorations and clothing twice a year, this size keeps everything organized and accessible.
What Is the Best Way to Reserve a 5x5 Storage Unit Online and Get Discounts?
Most facilities allow you to reserve online with no upfront payment. Here is how to get the best deal:
Check for web-only pricing. Many operators offer rates on their website that are $5 to $15 per month lower than walk-in rates.
Ask about first-month promotions. First month free, first month at $1, and 50% off the first month are all standard promotions in the industry. If you do not see a deal advertised, call and ask.
Look for referral discounts. Some facilities offer statement credits for referring new tenants. If a friend or family member already rents at the facility, ask them for a referral code before you sign up.
Time your move-in. Demand for storage tends to peak from May through September. Booking in the off-season (October through March) can yield better rates and more unit availability.
Reserve your 5x5 unit at Good Boy Storage and check current promotions at your nearest location.
How Secure Are 5x5 Storage Units?
Security varies dramatically from facility to facility. At a minimum, any reputable storage facility should have gated access with individual entry codes, video surveillance covering unit hallways and common areas, and adequate lighting throughout the property.
Higher-end facilities add features like individually alarmed unit doors, on-site management during business hours, and motion-activated lighting. Indoor units with controlled hallway access are generally more secure than outdoor drive-up units, though drive-up units offer easier loading access for bulky items.
Your own security practices matter too. Use a high-quality disc lock rather than a standard padlock, as disc locks are significantly more resistant to bolt cutters. Never share your access code, and always lock your unit even during loading and unloading.
The Federal Trade Commission offers consumer guidance on protecting personal property that applies directly to self-storage decisions.

Is a 5x5 Storage Unit Worth It?
For the right use case, a 5x5 unit offers exceptional value. At $40 to $65 per month, you are paying roughly $1.50 to $2.50 per day for 25 square feet of dedicated, secure space.
A 5x5 unit is worth it when:
- You need to free up closet or garage space at home
- You are between moves and need temporary overflow storage
- You store seasonal items that take up valuable living space for months at a time
- You want a secure place for documents, small electronics, or collectibles
- You are a college student needing summer storage for dorm belongings
A 5x5 unit might not be worth it when:
- You could solve the problem by decluttering and donating
- You are storing items worth less than a few months of rent
- You need the items more than once or twice a year and the facility is not conveniently located
The honest answer is that a 5x5 unit pays for itself when it protects valuable items or reclaims meaningful space in your home. If neither of those applies, consider whether the items are worth storing at all.
Choosing the Right 5x5 Storage Unit
After a decade in this industry, the advice I give to every first-time renter is the same: size your unit for what you have today, not what you might store later. A 5x5 unit handles seasonal items, document storage, and small furniture overflow better than any other unit size at its price point. If you find yourself thinking "I might need something bigger," rent the 5x5 first. Most facilities allow you to upgrade to a larger unit without penalty if your needs change, and you will avoid paying for space you do not use.
Prioritize security and access convenience over saving $5 per month. A facility with individual unit alarms, gated access, and a location close to your daily routine will serve you far better than a cheaper option across town that you never visit.
And always, always ask about promotions. The self-storage industry is competitive. Facilities want your business, and the best deal is rarely the one listed on the first page you see.
