What Size Storage Unit Do I Need?
A Simple Storage Unit Size Guide

Choosing the right storage unit doesn’t have to be a guessing game. The right size depends on how much you’re storing, the size of your largest items, and whether you’ll need room to access your belongings after you move in.

At Superior Storage in Hutchinson, Kansas, we offer storage units ranging from 7x10 to 13x43, with options for everything from clearing out a room or garage to storing the contents of an entire home or creating extra space for your business.

Not sure where to start? This guide will help you compare your options and find the amount of space that makes sense for you.

Storage Unit Size Guide

Our storage units generally fall into four categories: small, medium, large and extra-large.

Use the guide below to compare available sizes, then keep reading for a closer look at what you can expect to fit in each category.


 

Small Storage Units

Sizes to consider: 7x10, 8.5x10 and 10x10

Our small storage units offer approximately 70 to 100 square feet of floor space and are a great place to start if you’re looking to reclaim some space at home without storing the contents of an entire house.

What can fit in a small storage unit?

Depending on the exact unit size and how you pack it, a small storage unit may accommodate:

·         A mattress and box spring

·         Bedroom furniture

·         A sofa or loveseat

·         A dresser

·         A small dining table and chairs

·         Bicycles

·         Holiday decorations

·         Lawn and garden equipment

·         Boxes and storage totes

These units can be a good fit for apartment storage, college students, seasonal items, a room remodel, decluttering or clearing some much-needed space out of the garage.

A 10x10 storage unit provides approximately 100 square feet of floor space — roughly comparable to an average bedroom — and is a versatile option for storing furniture, boxes and belongings from several rooms.

Medium Storage Units

Sizes to consider: 14x10, 10x16 and 13x16

Need more than an extra room’s worth of space? Our medium units range from approximately 140 to 208 square feet and begin to provide the kind of space you might associate with a small garage.

What can fit in a medium storage unit?

Depending on the unit you select, you may be able to store:

·         Multiple bedroom sets

·         Living room furniture

·         Dining room furniture

·         Mattresses

·         A washer and dryer

·         A refrigerator and other appliances

·         Outdoor furniture

·         Lawn equipment

·         Garage contents

·         Numerous boxes and totes

Medium units are worth considering if you’re moving, remodeling, downsizing or storing the contents of several rooms or a smaller home.

They’re also a good middle ground when a 10x10 feels a little too tight but you don’t need one of our larger garage-sized spaces.

Large Storage Units

Sizes to consider: 10x21, 13x21 and 10x27

Our large storage units provide approximately 210 to 273 square feet of floor space, comparable to a one-car or oversized garage.

That extra room opens up considerably more possibilities.

What can fit in a large storage unit?

A large unit may accommodate:

·         Furniture from multiple bedrooms

·         Full living and dining room sets

·         Major appliances

·         Garage contents

·         Outdoor equipment

·         Large quantities of boxes and totes

·         Business inventory and supplies

·         Some vehicles, depending on vehicle and entrance dimensions

These units can be especially helpful for whole-home moves, major remodeling projects, business inventory, equipment storage or situations where you need to combine furniture and household belongings with larger items.

If you’re planning to store a vehicle, we recommend measuring both the vehicle and the unit entrance before selecting a unit.

Extra-Large Storage Units

Sizes to consider: 13x27, 10x43 and 13x43

Sometimes you need more than a typical storage unit.

Superior Storage’s extra-large units range from approximately 351 to 559 square feet, giving you substantial room for larger moves, business needs, equipment and other major storage projects.

What can fit in an extra-large storage unit?

Depending on the size you choose, these units may accommodate:

·         Contents of a larger home

·         Multiple furniture sets

·         Major appliances

·         Large quantities of boxes and totes

·         Business inventory

·         Contractor tools and supplies

·         Lawn and outdoor equipment

·         Large equipment

·         Vehicles, depending on dimensions

Our largest 13x43 storage unit provides approximately 559 square feet of floor space. These extra-large options can be especially useful for business owners, contractors, large household moves or anyone who simply needs significantly more room.

How Do I Know Which Storage Unit Size I Need?

If you’re standing in your garage or living room wondering how you’re supposed to translate a pile of belongings into square footage, you’re not alone.

Instead of trying to calculate everything perfectly, start with these four steps.

1. Make a Quick Inventory

You don’t need to count every box. Start by identifying the biggest things you plan to store.

Think about:

·         Beds and mattresses

·         Sofas and chairs

·         Appliances

·         Tables

·         Dressers

·         Outdoor equipment

·         Vehicles or large equipment

Your largest items will usually give you a better starting point than trying to estimate the number of boxes you’ll have.

2. Measure Your Largest Items

If you have anything unusually large or long, grab a tape measure before choosing your unit.

This is especially important for vehicles, large appliances, oversized furniture, equipment and other items where a few inches can make a difference.

3. Decide Whether You Need Room to Walk Around

There’s a difference between asking “Will everything fit?” and “Will I be able to get to anything once it does?”

If you’re storing belongings during a move and won’t need them again for several months, packing your unit tightly may make sense.

If you’ll regularly visit your unit to retrieve seasonal items, business inventory, tools or other belongings, consider leaving a walkway down the middle. That may mean choosing a slightly larger unit.

4. When in Doubt, Give Yourself a Little Extra Room

It’s easy to underestimate how much space furniture and boxes take up once everything is together.

If you’re deciding between two sizes and expect to access the unit regularly, a little extra room can make your storage space much easier to organize and use.

What Size Storage Unit Do I Need for Moving?

Moving is one of the most common reasons people need temporary storage, but the right unit depends more on how much you own than the number of bedrooms printed on your home’s listing.

As a general starting point:

·         Apartment or a few rooms: Start with our small units.

·         Small home: Consider our medium units or multiple small units.

·         Larger home: Look at our large units.

·         Large home or significant amount of belongings: Consider one of our extra-large units.

These are guidelines rather than hard rules. A minimalist two-bedroom apartment and a fully furnished two-bedroom home can require very different amounts of storage.

What Size Storage Unit Do I Need for Business Storage?

Storage units aren’t just for moving and decluttering.

For a small business, renting storage space can provide room for inventory, supplies or equipment without taking up valuable space at home or committing to additional office, retail or warehouse space.

Storage can be useful for:

·         Contractors storing tools, equipment and supplies

·         Retail businesses storing excess or seasonal inventory

·         Property managers storing maintenance supplies

·         Realtors and home stagers storing furniture and décor

·         Offices storing furniture, supplies or records

·         Seasonal businesses storing equipment during the off-season

A small business with boxes or supplies may only need a small or medium unit, while contractors and businesses carrying significant inventory or equipment may benefit from one of our large or extra-large units.

Frequently Asked Questions About Storage Unit Sizes

What is the most common storage unit size?

A 10x10 is one of the most recognizable and versatile storage unit sizes. It provides approximately 100 square feet of floor space and can work well for apartment contents, furniture, boxes, seasonal belongings and household overflow.

How much can you fit in a 10x10 storage unit?

A 10x10 storage unit can typically hold furniture and belongings from several rooms, including items such as mattresses, bedroom furniture, a sofa, dining furniture, appliances and moving boxes. Exactly how much will fit depends on the size of your belongings and how efficiently the unit is packed.

Should I rent a storage unit slightly larger than I think I need?

If you’ll need regular access to your belongings, having some extra space can be very helpful. A slightly larger unit gives you room to create an aisle, organize your belongings and retrieve items without unloading half the unit first.

Can I stack furniture in a storage unit?

Yes, when it can be done safely. Disassembling tables and bed frames, storing appropriate items vertically and making use of vertical space can help maximize your unit. Avoid unstable stacks or placing heavy items on furniture that could be damaged.

Can I store a vehicle in a storage unit?

Some of Superior Storage’s larger units may accommodate vehicles. Because vehicle and unit entrance dimensions vary, measure your vehicle and confirm the dimensions of the unit and entrance before renting for vehicle storage.

What if I’m still not sure what storage unit size I need?

That’s okay. Make a list of the largest items you plan to store and contact Superior Storage. We can help you narrow down which available unit sizes are likely to work best.
