5x15 Storage Unit: What Fits? What Doesn't?

If you’re running out of space at home or in the office, a 5x15 storage unit might be exactly what you need. This popular storage size strikes a balance between compact and roomy—perfect for stashing everything from seasonal gear to small furniture. But just how big is a 5x15 unit, and what can you actually fit inside? In this guide, we’ll break down the dimensions, what fits (and what doesn’t), pricing, and who should consider renting one.

How big is a 5x15 storage unit?

A 5x15 storage unit is 5 feet wide by 15 feet deep. That will give you 75 square feet of floor space. The average storage unit is approximately 8 feet high, providing approximately 600 cubic feet of storage space.

A 5x15 storage unit falls into the “small storage” category. It’s comparable in size to a large walk-in closet and is about half the length of a standard garage. 

5x15 Storage at a Glance:

• Dimensions: 5 feet wide by 15 feet deep by 8 feet tall
• Floor Space: 75 square feet
• Cubic Feet of Storage Space: 600
• Comparable To: Large Walk-in Closet
• Half the Length of a Standard Garage

What Does a 5x15 Storage Unit Look Like?

Picture a long, narrow hallway-shaped space, about as wide as a single-car parking spot but stretching back three times as far. There's enough width for a single row of boxes or furniture along one wall with a walkway down the other side, or you can line both walls and leave a path down the middle. 

It’s basically a deep closet you can organize, with room to slide a mattress in standing up, add metal shelving and stack boxes, or park a motorcycle at the back.

What items fit in a 5x15 storage unit?

A 5x15 may appear small, but, surprisingly, it can hold quite a lot! It’s great for household and business storage needs. A 5x15 self-storage unit can hold:

• Contents from a dorm room or a small apartment or studio

• Small couch or loveseat

• Mattress, bed frame, and box spring

• Dresser

• Several boxes

• A motorcycle or bikes

Can I Store a Vehicle in a 5x15 Unit?

A 5x15 works well for storing motorcycles and bikes, but it's not built for cars, trucks, or SUVs. While some 5x15s may have drive-up access, the narrow width doesn't leave enough room to maneuver a vehicle in and out safely. 

If you need vehicle storage for a car or truck, a 10x20 drive-up storage unit is a better fit. For motorcycle-specific tips, check out our motorcycle storage guide.

What won’t fit in a 5x15 storage unit?

Large items typically will not fit in this small storage unit. Some items that will not fit in this size storage unit include:

• Large dining room set with more than 4-6 chairs

• Oversized headboards or footboards, especially those with a canopy

• Full living room sets

• Sectional sofa

• Multiple couches

• Commercial freezers

• Large business inventory, including full shipments on pallets or bulky storage boxes

• Canoes, small boats, and jet skis

• Ride-on lawnmowers and tractors

While some 5x15s may have drive-up access, they cannot accommodate a vehicle. Cars, trucks, and SUVs are too large. If you’re looking for vehicle storage, consider renting a 10x20 drive-up storage unit.

Who should use a 5x15 storage unit?

A 5x15 is a great storage solution for almost anyone seeking extra space. We recommend this size storage space if you’re:

• Moving from a one-bedroom apartment or studio: During a transition from a small rental, a 5x10 will provide enough space for your furniture, boxes, and small appliances. A 5x15 can also hold all mattress sizes, including a king and queen-size bed

• Needing Student Storage: College students may need temporary, month-to-month storage between semesters, while studying abroad, or interning in another city. A 5x15 is affordable and can hold more than a 5x5 or 5x10.

• Renovating: Temporarily store your furniture and household items while remodeling a room

• Small Business Owners: A 5x10 can accommodate your extra business inventory, marketing materials, files, tools, or seasonal items. Month-to-month leases mean you can move into a larger unit, like 10x10 storage units, as your business scales

• Frequent Travelers: Use a small storage solution to house your travel gear - and even seasonal equipment, such as golf clubs, skis, kayaks, and camping gear

• Snowbirds: Store your seasonal belongings and other personal items while living somewhere else for a portion of the year

• Motorcycle Enthusiasts: Need a home for your motorcycle? A 5x15 can accommodate your bike! 

Climate-Controlled 5x15 Storage Units

If you need to store sensitive items, select a climate-controlled storage unit. These units are typically maintained at a temperature between 55°F and 80°F. This range is critical as temperatures below 55°F risk freezing and condensation. In contrast, temps over 80°F can lead to warping, melting, and other damage.

Select a climate-controlled unit if you’re storing wood or leather furniture, electronics, artwork, antiques, stamps, delicate clothing and fabrics, your wine collection, documents, and other significant collectibles.

How much do 5x15 storage units cost?

5x15s are often quite affordable, but prices do vary! Like all storage spaces, the price will be dependent on location, time of year, availability, and whether you’re renting climate-controlled storage.

What is the best way to organize a 5x15 storage unit?

5x15 units are deep and narrow, making them perfect for shelving units or couches. But organizing your unit properly will help you get the most out of your rental. Here are a few storage unit organization tips: 

• Plan Ahead: Make a layout of where you plan to place your items, especially your large boxes and furniture. Also, plan to group similar items (e.g., kitchenware, seasonal decor, office supplies, etc.). Be sure to label your boxes for easy access. 

• Load Largest Items First: Put your furniture, mattresses, and appliances in your unit first. If possible, store your sofa vertically to save floor space (but be sure to secure it to the wall so it doesn’t tip over).

• Use Uniform Boxes: This will lead to easier stacking and better stability.

• Leave a Center Aisle: Don’t just cram everything into the unit. Create a center walkway so you can actually access your things. 

• Use Freestanding Shelving: This will maximize your storage space.

• Elevate: Use pallets or boards to keep good furniture, antiques, and boxes off the floor. This will help protect them from moisture.

How does a 5x15 compare to a 5x5 storage unit?

While both are considered small storage options, a 5x15 will give you 75 square feet of floor space. A 5x5 is much smaller, with only 25 square feet.

For both unit sizes, utilize the vertical space of the unit. It will provide you with additional square feet of storage space, without having to size up to a medium-sized storage unit.
