Finding the right storage unit size can make all the difference between a cluttered, cramped space and one that’s efficiently organized and easy to access. Whether you’re moving, downsizing, or simply decluttering your home, understanding your storage options helps you save time, money, and stress.

At Dove Storage, we offer a range of unit sizes designed to fit every need—from small personal items to large furniture and business inventory. Here’s a complete guide to help you choose the perfect fit.

1. Start by Assessing What You Need to Store

Before choosing a unit size, take inventory of what you plan to store. Are you packing away boxes of household items, or do you need space for furniture and appliances? Write down larger items—like mattresses, sofas, or dining tables—and group smaller ones into boxes or bins.

Pro Tip: Stackable boxes and uniform containers help maximize your space and make it easier to plan the right size.

Ask yourself:

Will I need frequent access to these items?
Are there fragile or bulky pieces that need extra space?
Do I plan to add more items later?

Once you have a clear list, you’re ready to match your needs to a storage unit size.

2. Understanding Common Storage Unit Sizes

Every storage facility has its own range of sizes, but here’s a general breakdown of the most popular options available at Dove Storage:

5x5 Unit – Small Closet Size

Perfect for boxes, seasonal décor, personal documents, and small furniture.

Ideal for: Students, renters, or anyone looking to clear out a closet or home office. Comparable to: A small walk-in closet.

5x10 Unit – Walk-In Closet Size

Holds the contents of a small room—like a twin bed, dresser, and several boxes.

Ideal for: One-bedroom apartments or small storage projects. Comparable to: A large walk-in closet.

10x10 Unit – Half Garage Size

A great mid-size option that fits the contents of a one- to two-bedroom apartment, including furniture, appliances, and boxes.

Ideal for: Families or individuals moving between homes. Comparable to: Half of a standard garage.

10x15 Unit – Large Apartment Size

Spacious enough for several rooms’ worth of items, including large furniture, bikes, and appliances.

Ideal for: A two- to three-bedroom home or long-term storage during renovations. Comparable to: A large bedroom or small garage.

10x20 Unit – Standard Garage Size

Accommodates the contents of a full home or small business inventory. Some even use it for vehicle storage, depending on the location.

Ideal for: Families relocating or storing vehicles and large items. Comparable to: A one-car garage.

10x30 Unit – Extra-Large Space

The largest size typically available. Holds the contents of a large home, including furniture, appliances, and boxes from multiple rooms.

Ideal for: Full-house moves, business storage, or long-term inventory needs. Comparable to: A two-car garage.

3. Consider Climate-Controlled vs. Standard Storage

Depending on what you plan to store, choosing between standard and climate-controlled units can be an important factor.

Climate-Controlled Units: Best for temperature-sensitive items such as wood furniture, electronics, artwork, and important documents. These units maintain a steady environment year-round to help prevent damage from humidity and heat.
Standard Units: Great for general items, garage tools, outdoor equipment, or anything that’s not affected by temperature changes.

If you’re unsure, it’s always better to choose climate control for long-term peace of mind—especially for valuable or delicate belongings.

4. Maximize Your Space with Smart Packing

No matter which unit size you choose, organization makes all the difference.

Use sturdy, same-size boxes for easier stacking.
Label everything clearly by room or category.
Use shelving units to take advantage of vertical space.
Keep frequently used items near the front for easy access.
Create a small aisle so you can reach boxes in the back without having to move everything around.

Pro Tip: Take a quick photo of your packed unit—it’ll help you remember where things are and track what’s stored.

5. Choosing the Right Size with Confidence

If you’re still unsure which size fits your needs, try visualizing your belongings in a room of similar dimensions—or visit our Dove Storage Size Guide for an easy visual reference. Our online guide helps you compare unit sizes side by side and see exactly what each can hold.

Remember: It’s usually better to size up slightly rather than squeeze items into a smaller unit. You’ll have room to move around, stay organized, and avoid accidental damage to your belongings.
