Whether you’re moving, downsizing, decluttering, or just need extra space for your belongings, renting a storage unit can be a convenient and affordable solution. But one of the most common questions people ask is: What size storage unit do I need? Choosing the right size is key – not only to make sure all your items fit, but also to avoid paying for space you won’t use.

At Rancho San Diego Self Storage, we offer a wide range of unit sizes across our many convenient locations to accommodate just about every need. Here’s a helpful guide to help you determine which unit is right for you.

1. Start With an Inventory List

Before choosing a storage unit, take stock of what you plan to store. Create a list of your items – furniture, boxes, appliances, seasonal items, etc. – and estimate the quantity and size of each. This will help you get a better idea of how much space you’ll need and whether you’ll require additional features like climate control.

2. Understand Common Storage Unit Sizes

While sizes may vary slightly depending on location, here are the most common unit sizes and what they typically hold:

5×5 Storage Unit (25 sq. ft.)

About the size of a small closet. Ideal for:

• Small furniture (end tables, lamps)
• Boxes and totes
• Seasonal décor
• Office supplies or personal records

5×10 Storage Unit (50 sq. ft.)

Roughly the size of a walk-in closet. Ideal for:

• A mattress set
• Small couches or chairs
• Dressers and shelving
• Several medium-sized boxes

10×10 Storage Unit (100 sq. ft.)

Fits the contents of a one-bedroom apartment. Ideal for:

• Larger furniture items (bedroom or living room sets)
• Appliances
• Dozens of boxes

10×15 Storage Unit (150 sq. ft.)

Suitable for a two-bedroom home or apartment. Ideal for:

• Multiple furniture sets
• Larger appliances
• Outdoor equipment or motorcycles

10×20 Storage Unit (200 sq. ft.)

Great for a three- to four-bedroom house. Ideal for:

• Full household contents
• Business inventory
• Garage overflow

10×30 Storage Unit (300 sq. ft.)

Perfect for large homes or commercial storage. Ideal for:

• Extensive furniture and appliances
• Multiple rooms’ worth of belongings
• Business equipment and files

3. Consider How Often You’ll Access Your Items

Will you be visiting your storage unit often to grab things? If so, you’ll want to leave space to walk in and move around. In this case, it’s smart to size up slightly to make room for shelving or an aisle down the center. Rancho San Diego Self Storage offers flexible unit options so you can choose based on both volume and convenience.

4. Think Vertically

Storage units typically have high ceilings, so don’t forget to stack! Use sturdy boxes and place heavier items on the bottom, lighter ones on top. Use vertical shelving to make use of every inch. A well-packed unit can often hold more than you’d think.

5. Match the Unit Size to Your Life Situation

Here are a few real-life scenarios and recommended sizes:

• College Student During Summer Break: 5×5 or 5×10 unit
• Home Renovation Storage: 10×10 or 10×15 unit
• Military Deployment or Extended Travel: 10×15 or 10×20 unit
• Business Storage (files, inventory, equipment): 10×10 to 10×30 depending on need
• Moving Between Homes: 10×15 to 10×30, depending on household size
