Sometimes, all you need is a little space to make room for a lot more in life.

Have you ever looked around your home and thought, “Where did all this stuff come from?” You’re not alone.

According to the Self-Storage Association, nearly 1 in 10 households in the U.S. rent a storage unit, and one of the most popular options is the 10x20 storage unit.

It’s spacious, affordable, and surprisingly versatile — but just how big is it, and what can it really hold?

Imagine a space about the size of a standard one-car garage; that’s roughly 200 square feet of floor space. However, with nearly 1,600 cubic feet of usable space, a well-packed 10x20 storage unit can store more than you might expect.

If you're wondering what fits in a 10x20 storage unit or if it’s even worth it, you’re in the right place. In this guide, let’s break down everything you need to know about a 10x20 storage unit.

Understanding the Size of a 10x20 Storage Unit

If you've never used self-storage before, a 10x20 storage unit might sound straightforward, but it can actually store quite a bit.

Exact Dimensions and Volume

A standard 10x20 storage unit is:

  • 10 feet wide
  • 20 feet deep
  • Usually around 8 feet tall

This gives you a total of:

  • 200 square feet of floor space
  • 1,600 cubic feet of storage volume

That’s enough space to hold the contents of a multi-bedroom home, a full garage, or even a small moving truck.

What Does That Size Look Like in Real Life?

To help you visualize it, a 10x20 storage unit is similar in size to:

  • A standard one-car garage
  • A 26-foot moving truck (comparable storage capacity)
  • A small studio apartment
  • Half of a two-car garage

If you're storing boxes or bins, you could easily fit:

  • Around 200–250 medium-sized boxes
  • Large furniture like sofas, beds, dressers, and appliances stacked on top
  • Seasonal gear like skis, holiday decorations, or camping supplies

Layouts May Vary Slightly

Not every 10x20 storage unit is built the same. Depending on the facility, you might find:

  • Taller ceilings (some go up to 10 ft)
  • Wider units for easier access
  • Indoor vs. drive-up access points

All of these can affect how much and what you can store. That’s why it’s helpful to check the unit type and layout when reserving.

Types of 10x20 Storage Units

While every 10x20 storage unit offers the same amount of floor space, the type of unit you choose can impact how you use it. Most self-storage facilities offer a few different types to match various needs, whether you’re storing personal items, business supplies, or seasonal gear.

Let’s take a look at the most common types of 10x20 storage units.

Indoor 10x20 Storage Units

Indoor units are located inside the storage building and are typically accessed via secure, climate-controlled hallways. This setup provides added protection from the weather, pests, and dust.

Benefits of indoor units:

  • Often climate-controlled
  • Protected from outdoor elements
  • Well-lit, clean, and secure
  • Ideal for storing electronics, documents, clothes, or collectibles

Outdoor 10x20 Storage Units

Outdoor units are accessible from the outside of the building, often with drive-up access similar to a small garage. These are great if you want quick and easy loading or unloading.

Best for storing:

  • Heavy items like small furniture or bins
  • Tools and equipment
  • Items you access frequently

Outdoor 10x20 storage units are typically not climate-controlled, so they're better suited for belongings that are not temperature-sensitive.

Climate-Controlled 10x20 Storage Units

Climate-controlled storage keeps your items in a stable temperature and humidity range, which helps protect them from damage due to heat, cold, or moisture. These units are especially useful for delicate or valuable items.

Perfect for storing:

  • Wooden or leather furniture
  • Photos, books, or documents
  • Electronics or musical instruments

Climate-controlled 10x20 storage units are typically indoor units, but some facilities may also offer outdoor versions with temperature control.

Special Features & Add-Ons to Look For

  • 24/7 surveillance cameras
  • Gated access with keypads or app-based entry

  • Carts and dollies available onsite

  • Elevator access for multi-story indoor facilities
  • Drive-up access for outdoor 10x20 units
  • Wide hallways and loading bays for easier movement

Especially if you’re moving heavy boxes or furniture into your 10x20 storage unit, these extras can save time and your back.

Digital Tools & Support

Modern storage facilities often come with digital conveniences that make managing your unit even easier:

  • Online rentals and payments
  • Mobile app for gate access
  • Auto-billing and reminders
  • Virtual unit tours or size guides

If you're comparing facilities, don’t just look at price — check what kind of support and tech they offer, too.

Tips to Maximize Space in a 10x20 Unit

How Big Is a 10x20 Storage Unit?

A 10x20 storage unit gives you a generous amount of space — but to get the most out of it, you need to pack strategically. Whether you're storing for the short or long term, using these tips can help you stay organized and make every square foot count.

Use Uniform Boxes

Stick to the same size boxes whenever possible. This makes stacking easier and safer, maximizing your vertical space without the risk of toppling.

Label Everything Clearly

Label all boxes on multiple sides with their contents. This saves time when searching and avoids unnecessary digging or unpacking.

Disassemble Large Furniture

Take apart bed frames, tables, and other bulky items. Store flat components vertically to save floor space.

Store Vertically

Think in terms of cubic feet, not just square footage. Stack boxes and bins up to the ceiling, placing heavier items on the bottom and lighter ones on top.

Create Aisles for Access

Leave small walkways or access paths so you can reach items in the back without having to unload the entire unit.

Use Shelving Units

Freestanding shelving lets you use vertical space while keeping items off the floor — especially good for fragile or frequently accessed items.

Store Items Inside Other Items

Place smaller items inside dressers, drawers, or even appliances (like clean fridges or washing machines) to make use of hidden space.
