10x15 Storage Unit: What Fits? What Doesn't?

When it comes to self-storage, choosing the right unit size can feel like a puzzle. Too small, and you’ll be frustrated with a lack of space. Too large, and you might end up paying for square footage you don’t need. A 10x15 storage unit offers a versatile, mid-size solution for both personal and business storage needs. But, how much can it hold?

In this guide, we'll break down the dimensions, show you exactly what fits, and help you decide if this size is right for your needs. Plus, we'll share real pricing examples and pro tips on how to make the most of your space.

How large is a 10x15 storage unit?

10x15 storage units are 10 feet wide by 15 feet deep, giving you approximately 150 square feet of floor space. The typical storage unit is around 8 feet high, so you will have around 1,200 cubic feet of total storage space.

To better visualize, think of a 10x15 as comparable to a large bedroom or a small one-car garage. These spacious units can fit the contents of a two-bedroom apartment or small home.

What fits in a 10x15 unit?

A 10x15 storage unit is exceptionally spacious and can, unsurprisingly, accommodate a substantial amount for both household and business storage needs. Some items that can fit into a 10x15 unit include:

• Sofas (2-30) or a sectional (1)
• Dining room sets with 4-6 chairs
• Queen and king bed sets, including the mattress and bed frame
• 25-30 large boxes or 30-40 medium boxes
• Oversized exercise equipment, including treadmills
• Refrigerators, chest freezers, and washer/dryer sets
• Lawn mower and snowblower
• Office furniture, such as desks, chairs, and filing cabinets
• Tradeshow equipment and displays

If you're undecided between renting a 10x10 and a 10x15 storage unit, we recommend opting for the larger 10x15. Why? It's easier to get extra space when you first rent than to transfer and move to a larger unit in the future. Try to anticipate your future storage needs. If you're using the space for long-term storage or business inventory, it's better to opt for the larger unit.

What won't fit in a 10x15?

Although a 10x15 is a spacious storage solution, some items simply won't fit. These items include:

• Cars, boats, and RVs 
• Huge furniture sets, such as full-sized sectional sofas and bulky entertainment systems
• Construction materials in bulk, such as pallets of lumber and drywall
• A full kitchen's worth of appliances: think fridge, stove, washer/dryer set, and dishwasher. It will get extremely cramped

If you need storage space during a move, consider the size of your current home. If you have a 3+ bedroom home, a 10x15 will not be large enough for your contents. But, if you only need partial storage for your home (ex, during a renovation), this size would be suitable. 

Will a vehicle fit in a 10x15 storage unit?

While a compact car (around 14-15 feet long) may technically fit in a 10x15, it's barely enough room. There will be no room to walk around the vehicle or comfortably close the door. So, we do not recommend renting a 10x15 for vehicle storage.

If you're looking for vehicle storage, the ideal size for most vehicles is a 10x20 storage unit. For oversized trucks, large SUVs, and work vans, a 10x25 or larger is the best option.

Who should rent a 10x15 storage unit?

If you need a medium-sized storage space, a 10x15 is a great option. Some individuals who will benefit from renting this size storage solution include:

• Empty Nesters: If you're downsizing once the kids move out, this is an excellent solution for you. 
• Moving: Since these units can hold the contents of a small home, they are well-suited for use between moves or when staging a home for sale. It's also great if you're moving out of your first apartment post-college and into a new townhouse.
• Homes Without Basements: In many areas, homes do not have basements, so a 10x15 can help provide you with the additional personal storage space you need. Pack away your seasonal furniture and decor, sports gear, and extra furniture.
• Military Personnel: These units, along with 10x10s, are optimal for short-term storage during deployment.
• Remote or Hybrid Teams: If you're downsizing on office space because your teams work from home, use a 10x15 to store your unused office furniture and equipment. It's great to hang onto these items in case you require RTO in the future.
• Seasonal eCommerce Businesses: Have seasonal stock that rotates throughout the year? Use this size storage unit to house your inventory and packing materials.

How much does a 10x15 storage unit cost?

The cost of a self-storage unit depends on several factors, including location, features, seasonality, and the amenities offered by the facility. Price may increase (or decrease) based on:

• Proximity to major cities, highways, and other desirable locations
• Climate-controlled versus standard, non-climate-controlled
• Ground floor accessibility versus units on a higher floor
• Time of the year: Self-storage is more in demand from May through September
• Promotions offered: Look for discounted web-only rates, first-month promotions, and military discounts. Storage Star offers all three on most unit sizes, including 10x15s.

How should I arrange my 10x15 storage unit?

Even though you have 150 square feet of floor space, you still want to pack your unit efficiently. Maximize your space while keeping everything you need easily accessible. Some of our top tips include:

• Creating an inventory list so you know what you're storing - this will also come in handy when creating a layout of how you want to store everything
• Use the same-size moving boxes. They'll be easier to stack.
• Clearly label all of your boxes, and label them on all sides for visibility.
• Disassemble your furniture. Make sure you are storing screws and bolts in labeled bags. Tape the bag to the piece of furniture the hardware is for.
• Load larger items in the back and along the sides. 
• Create a U-shaped layout in your unit. This will make it easy to access everything at a later date.
• Cover your furniture with blankets and sheets. Use a mattress cover, sold at Storage Star, to protect your mattresses and box springs.
• Stack your boxes and items up to approximately 7 feet high. We do recommend leaving some room above for airflow.

Still unsure? When in doubt, it’s better to size up and give yourself a little breathing room, especially if your storage needs might grow over time.
