What Size Storage Unit Do I Need? The Complete 2026 Guide

If you're sitting in your South Tulsa living room staring at a pile of boxes, a sectional sofa that's not fitting in the new place, and three generations of dining room furniture, you've already figured out that most Woodland Hills homes have one problem: too many nice things and nowhere to put them all.

How Much Space Do You Really Have?

Before we talk about unit sizes, let’s first talk about what’s actually sitting in your house right now.

If you live in one of the bigger South Tulsa homes near LaFortune Park, you probably have a two-car garage. It’s likely already full of tools, bikes, lawn equipment, and holiday decorations. Your basement may also be hitting capacity. Maybe you’re moving, downsizing after the kids left, or your home office took over the guest bedroom. In any case, you need to know how much space your things actually take up.

Here’s the honest truth: most people guess too low on size. They picture their bedroom furniture and think a 10×10 should be fine. Then they add the office desk, the bookshelf, and the file boxes from the garage. Suddenly they’re playing Tetris at midnight. So before you book, take a few minutes to count what you’re actually moving.

Storage Unit Sizes Explained: What Actually Fits

Here is a breakdown of each common size with real examples, not vague descriptions.

5×5 Storage Unit (25 Square Feet)

This size is tight. Think of it like a closet with a door or the space under a staircase, except you can stand up straight.

What fits: Small furniture only. For example, a single dresser and a nightstand. Ten to fifteen plastic storage totes. A few file boxes. Some seasonal decor. Your winter coats and holiday tree.

Real scenario: You’re between places for a month and need to store a desk chair, some file boxes, and your college textbooks. This size works well for that.

What doesn’t fit: A dining table, a bed frame, a couch, a shelving unit, or a motorcycle.

5×10 Storage Unit (50 Square Feet)

Still compact, but now you’ve got a narrow hallway of space. Think of it as the footprint of a small bedroom or a decent walk-in closet.

What fits: A queen-size bed frame, a dresser, a nightstand, and file boxes stacked along one side. Some plastic bins. A dining table without chairs. Small appliances. Boxes of books and kitchen items.

What doesn’t fit: A full sectional sofa, multiple large furniture pieces, or a full bedroom suite plus anything extra.

10×10 Storage Unit (100 Square Feet)

Now you’re talking about real, usable space. This is the most popular size and usually the right call for one bedroom’s worth of furniture plus kitchen items and seasonal storage.

What fits: A queen mattress and frame, dresser, nightstand, and bookshelf. A dining table with four chairs. A desk. Thirty to forty storage bins. Also, file boxes, seasonal decorations, sports equipment, and luggage all fit with room to spare.

Pro tip: With a 10×10, leave an aisle down the middle. That way you can actually reach things without moving everything around first.

10×15 Storage Unit (150 Square Feet)

This is the comfort zone size. It’s a decent-sized bedroom plus a hallway’s worth of floor space. Everything a 10×10 holds fits here too, plus a full sectional sofa, a second bedroom set, or a riding lawnmower. In fact, you could fit an entire two-bedroom apartment if you pack it smart.

10×20 Storage Unit (200 Square Feet)

Think of this as one-car garage territory. This size fits multiple bedrooms of furniture, a full living room, a dining room set, a washer and dryer, and a motorcycle. It also handles garden equipment and a complete office setup without a problem.

10×25 Storage Unit (250 Square Feet)

Think of it as a one-car garage plus an extra storage room. This size fits everything from a 2,500 square foot home, plus RV equipment, boat parts, multiple motorcycles, or months of small business inventory.

The Most Common Mistake People Make

Going Too Small Upfront

Here’s what happens. You estimate you need a 10×10, so you rent it. Two weeks in, you realize your dining table doesn’t fit the way you planned. Your office boxes are stacking too high. Your seasonal storage also takes up more room than expected. Then you either spend three months fighting a storage puzzle or upgrade to a 10×15, which costs extra money and creates a hassle.

The Simple Fix

The solution is simple: pick slightly bigger than you think you need. That extra $20 to $30 per month is much cheaper than the stress of running out of room. Instead of guessing, use the quick pick guide below to check what fits before you book.

What If You Pick Wrong?

You’re Not Locked In

Here’s the good news about Click Storage. You’re not stuck with the size you chose. If you rent a 10×10 and realize two weeks later that you need more space, you can upgrade to a 10×15. Similarly, if you overshot and you’re only using half the unit, you can also downsize and lower your monthly cost.

The locations in South Tulsa and across Oklahoma make it easy to adjust. There’s no long-term contract holding you to one size. Browse our personal self-storage options to find the right unit for your move.

Quick Pick Guide: Choose Your Size

  • Seasonal items only: 5×5 or 5×10
  • One bedroom’s furniture plus kitchen items: 10×10
  • Two bedrooms plus seasonal stuff: 10×15
  • Full house or major business inventory: 10×20 or 10×25
  • Motorcycle, boat, or RV: 10×15 minimum

The Bottom Line

Overall, most people in South Tulsa and the surrounding areas end up choosing a 10×10 or 10×15. These sizes give you enough room to use the space well without paying for square footage you’ll never fill.

If you’re uncertain between two sizes, go bigger. The price difference is small, and the peace of mind is worth it.

Tap to reveal answer

Climate controlled storage maintains temperature and humidity year-round, protecting delicate items from Oklahoma’s extreme heat and moisture swings. Standard storage does not regulate temperature. Climate control typically costs about $20-$40 more per month.

Question 04Should I upgrade to a bigger unit to be safe?
Tap to reveal answer

Yes, if you’re between two sizes. The monthly difference is usually small, and the extra space lets you access items, add shelving, and adjust things without frustration.

Question 05Can I downsize my unit later if I don’t use all the space?
Tap to reveal answer

Yes. Click Storage lets you change unit sizes based on your needs. If you overestimate initially, you can move to a smaller unit and reduce your monthly payment.

Question 06What fits in a 10×10 storage unit?
Tap to reveal answer

A 10×10 can fit a queen mattress and frame, dresser, nightstand, bookshelf, dining table with four chairs, a desk, and 30-40 plastic storage bins. It is the most popular size for one-bedroom home transitions.

Question 07Is a 5×5 storage unit big enough for seasonal items?
Tap to reveal answer

For seasonal decor, winter coats, and a few boxes, yes. A 5×5 is about the size of a large closet. You can fit 10-15 storage totes, holiday decorations, and some small furniture pieces.

Question 08How do I know what size I need for a two-bedroom apartment?
Tap to reveal answer

A 10×15 is typically right for two bedrooms’ worth of furniture plus seasonal items. If you’re also storing a large sofa or significant kitchen items, consider going up to a 10×20 to avoid running out of space.

Question 09What is the biggest storage unit available?
Tap to reveal answer

Most facilities, including Click Storage, offer up to 10×25, or 250 square feet. That’s equivalent to a one-car garage plus a storage room. It can handle the contents of a 2,500-square-foot home.

Question 10What’s the best unit size for business inventory?
Tap to reveal answer

A 10×15 works well for small business inventory, samples, and office equipment. For larger stock or equipment, a 10×20 gives you more room to work and access items easily.

Question 11How many boxes fit in a 10×10 storage unit?
Tap to reveal answer

Roughly 30-40 medium-sized boxes fit in a 10×10, depending on what else you’re storing. If you’re stacking boxes floor to ceiling on shelves, you can fit significantly more.

Question 12Can I move to a larger unit if I underestimate my needs?
Tap to reveal answer

Yes. Click Storage allows unit upgrades. If you rent a 10×10 and need more space, you can move up to a 10×15 or larger. It is often better to start slightly larger than to need an upgrade mid-storage.
