Ultimate Guide to Picking the Right Storage Unit Size

Ultimate Guide to Picking the Right Storage Unit Size

Choosing the right storage unit size can make all the difference in your moving or decluttering experience. Too small, and you’ll run out of room. Too large, and you may end up paying for space you don’t need. At Space Shop Self Storage, we make it easy to select the perfect fit with a clear and practical size guide designed to take the guesswork out of storage.

Whether you’re moving, renovating, downsizing, or simply creating extra space at home or work, planning ahead ensures you get the most value and convenience from your storage experience.

Why Storage Unit Size Matters

Selecting the right size unit helps you:

  • Stay within budget
  • Keep your belongings organized
  • Maximize usable space
  • Access items easily when needed
  • Reduce stress during move-in and move-out

Before choosing a unit, take inventory of everything you plan to store. Consider how long you’ll need the space and whether you expect to add items over time. Planning ahead prevents unnecessary upgrades or cramped conditions later.

Understanding Storage Unit Sizes

Here’s a breakdown of common storage unit sizes and what they typically accommodate, based on the Space Shop size guide.

Storage Lockers

Ideal for smaller needs, storage lockers are perfect for boxes, seasonal decorations, business records, or sports equipment. Think of this option as extra closet space outside your home.

5′ x 5′ (25 Square Feet)

About the size of a small walk-in closet. This unit works well for boxes, small furniture pieces, luggage, and personal items.

5′ x 10′ (50 Square Feet)

Comparable to a large shed. This size can hold furnishings from a small bedroom, including a mattress set, dresser, desk, and several boxes.

10′ x 10′ (100 Square Feet)

One of the most popular sizes. Roughly half the size of a standard garage, it can fit the contents of a one-bedroom apartment, including appliances and larger furniture.

10′ x 15′ (150 Square Feet)

A great option for storing items from a two-bedroom home or apartment. This size accommodates multiple furniture sets, appliances, and numerous boxes.

10′ x 20′ (200 Square Feet)

About the size of a standard one-car garage. Ideal for storing the contents of a three- to four-bedroom home, including large furniture and major appliances.

10′ x 30′ (300 Square Feet)

One of the largest standard sizes available. Perfect for full household storage, business inventory, equipment, or oversized items.

Vehicle Storage Options

Many locations also offer vehicle, boat, and RV storage. These options provide protection from the elements while freeing up space at home.

Tips for Planning the Right Size

Choosing the correct unit is not just about square footage — it’s about strategy.

Take a Detailed Inventory

Write down every item you plan to store, including bulky or awkwardly shaped pieces. This gives you a realistic sense of how much space you’ll need.

Think Vertically

Storage units have height, so stack strategically. Place heavier items on the bottom and lighter boxes on top. Disassemble furniture when possible to save space.

Leave an Access Path

If you anticipate visiting your unit regularly, leave a small aisle so you can reach items in the back without unloading everything.

Plan for Growth

If you expect to add items later, consider sizing up slightly now instead of moving to a larger unit down the road.

Ask the Experts

If you’re unsure, the Space Shop team can help you estimate the right fit based on your specific needs. A quick conversation can prevent overpaying or underestimating your space.

Make Storage Simple

The right unit size makes storage easier, more organized, and more cost-effective. Whether you’re clearing out a closet, staging a home, transitioning between moves, or storing business inventory, there’s a solution designed to fit your needs.

Planning ahead ensures you select a unit that works for you today and tomorrow. When you’re ready to find your perfect space, use the Space Shop size guide and let the team help you store with confidence.
