10x15 vs 10x20 Storage Units: Which Size Is Right for You?

When it comes to self storage, choosing the right unit size can make all the difference in convenience, cost, and organization. Two of the most common mid-sized options are 10x15 and 10x20 storage units. While they may sound similar, the difference in space and price can significantly affect your storage experience. Whether you’re moving, downsizing, or organizing your business inventory, understanding what each size offers will help you make the best decision.

Understanding the Dimensions: Square Footage and Cubic Space

Before deciding between the two, let’s start with the basics: how much space you’re actually getting.

That extra 50 square feet (and about 400 cubic feet of additional volume) in a 10x20 unit can make a big difference when you’re storing large furniture, vehicles, or bulky business supplies.

What Fits in a 10x15 Storage Unit?

A 10x15 storage unit is roughly the size of a large bedroom or small one-car garage, offering plenty of room for the contents of a two-bedroom apartment.

Here’s what typically fits:

• Bedroom and living room furniture (mattress sets, couches, dressers)
  
  

• Kitchen appliances or small dining sets
  
  

• 100–150 moving boxes
  
  

• Bicycles, lawn equipment, or seasonal décor
  
  

• Small business inventory or office furniture
  

Ideal for:
People moving from a small home or apartment, or those needing medium-term storage during renovations or relocations. It’s also a great option for businesses with moderate storage needs—like extra supplies, tools, or archive boxes.

What Fits in a 10x20 Storage Unit?

A 10x20 storage unit is closer to the size of a standard one-car garage, offering enough space to hold the contents of a three- to four-bedroom home.

You can typically fit:

• Large appliances (washer, dryer, refrigerator)
  
  

• Multiple bedroom sets or living room furniture
  
  

• Full dining sets or large sectionals
  
  

• Outdoor equipment, riding lawn mowers, or motorcycles
  
  

• 200–250 moving boxes
  
  

• Small vehicles, trailers, or compact cars (in drive-up units)
  
  

Ideal for:
Families moving between homes, people storing vehicles, or businesses with larger inventories and equipment. It’s also a smart choice if you prefer extra space to walk around or organize items inside your unit.

Typical Price Difference Between a 10x15 and 10x20 Unit

Prices vary by location, demand, and whether the unit is climate-controlled, but on average:

• 10x15 units typically range between $100–$160/month
  
  

• 10x20 units typically range between $130–$200/month
  

That’s roughly a 15–25% price difference, depending on market and amenities. For the added 50 square feet, many renters find the larger size a worthwhile upgrade—especially when avoiding the hassle of upgrading later.

Which One Should You Choose?

When deciding between a 10x15 and 10x20 unit, ask yourself the following:

1. What are you storing?
   If you’re only storing boxes and furniture from a smaller apartment, a 10x15 should suffice. But for larger households, business equipment, or vehicle storage, the 10x20 will provide necessary extra room.
   
   

2. Do you need room to maneuver?
   If you plan to access your items frequently, the extra walking and organizing space in a 10x20 can make it easier to find and retrieve things.
   
   

3. How long will you be storing?
   For short-term storage, a tighter fit might be okay. But for long-term storage, leaving some open space improves airflow and helps prevent damage to your belongings.
   
   

4. What’s your budget?
   The cost difference is modest compared to the convenience of more space—but if you’re on a strict budget, sticking to a 10x15 can still cover a lot of needs.
