Picking the right storage unit size doesn’t need to be a headache. But guessing wrong can leave you short on space or paying for air. The goal is to fit everything without wasting money. That means being clear about what you’re storing, how often you’ll need access, and how much room you want to move around.
If you’ve ever asked what size storage unit makes sense for your stuff, you’re in the right place. We’ll walk you through actual examples, a clear storage unit size chart, and some real advice from folks who pack these units daily.
Choosing the Right Storage Unit Size: Important Factors to Consider
The size of your home, what you’re storing, and how you plan to pack, all of it matters. You’re not just putting boxes into a metal box. You’re making sure nothing breaks, melts, or gets buried under something heavy. Below, we’ll break this down into simple categories to give you a better idea.
- 5×5 Storage Unit is Small but Mighty
This is the “hall closet” of storage. It is a good fit for a few small chairs, winter clothes, decorations, or files. People use this size when they’re storing holiday stuff or keeping personal boxes after moving out of a dorm.
But be warned, as packed units this small can turn into a tight squeeze if you try to cram in large furniture.
- 5×10 Storage Unit is One Room’s Worth
This one’s great if you’re clearing out a single room. It holds more than it seems. One person moving out of a shared apartment can usually make this work. Stack items carefully, place light boxes on top, and leave a narrow walkway if you’ll need to get back in.
- 10×10 Storage Unit for A Whole Apartment’s Contents
If you’re moving or remodeling and need to get things out fast, this is a popular size. You’ll be able to fit a queen mattress, a dresser, a TV stand, a coffee table, and boxes with ease. But don’t forget how you pack matters, as poor stacking turns a roomy space into a mess. Therefore, it is best to ask about packing tips or visit a few packed units on-site to see how others make it work.
- 10×15 Storage Unit for Two Bedrooms or a Garage Load
This size holds a lot. If you’re emptying a two-bedroom house or apartment, you’ll need this much space. It also works for storing business inventory, retail fixtures, or garage gear. We’ve seen this used during full home clean-outs after renovations, where people just wanted everything out of the way but kept it within reach.
- 10×20 Storage Unit for a Full House Storage
If you want something good for major moves, families between homes, or long-term storage, then the 10×20 storage unit is the optimal choice. This is where serious storage starts. It holds most of a standard house, such as furniture, appliances, and even large outdoor items.
For business use, it can also hold racks of products, shelves, and tools. People often rent this when they’re selling their home but haven’t closed on the next one yet.
- 10×30 Storage Unit for Everything Including the Kitchen Sink
Need space for a home and a workshop? This is the size you’ll need. Ideal for big furniture, large collections, or overflow from moving trucks. Contractors also rent this size to keep gear, supplies, and backup equipment. If you’re worried about having to dig through a maze of boxes, this unit leaves room to set up an aisle so nothing’s buried.
- Vehicle Storage and Specialty Sizes
Some locations offer units specifically for boats, RVs, and motorcycles. These aren’t standard, but can save money and prevent damage from outdoor weather. Ask the staff what’s available, especially if you need wide doors, extra height, or ventilation.

| 10×10 | Furniture, appliances, 20-30 boxes | Apartment contents |
| 10×15 | 2 bedrooms’ worth of furniture | Home transition, garage clean-out |

The Role of Staff in Choosing the Right Size
Here’s the truth: most people don’t know how much space they really need. That’s why talking to someone at the office can help.
At Karl Storage, the team sees packed units every day. They know what a 10×10 really holds and what it doesn’t. They won’t guess. They’ll ask what’s in your move, what you plan to do with the unit, and how long you plan to rent.
We understand that no two customers are the same. A one-bedroom apartment for one person might need more space if there’s antique furniture or a large collection of fragile items. That’s why the team doesn’t just go by square footage. They ask questions that actually help find you the best storage unit according to your needs and preferences.
