What Size Storage Unit Do You Really Need? A Practical Guide for Renters
When you're ready to rent a storage unit, one of the biggest questions is also one of the most common: What size do I need? Rent something too small, and you’ll be playing real-life Tetris with your belongings. Go too big, and you could end up paying for more space than you actually use. Let’s break it down with real-world examples, common pitfalls, and a few tips on how to adjust your storage space as your needs change.
What Fits in a 5x10, 10x15, and 10x20 Storage Unit?
Understanding what fits in each unit size is the best way to set realistic expectations.
5x10 Storage Unit (50 sq ft)
This is one of the most versatile and affordable options. Think of it as a large walk-in closet. It’s perfect for a single bedroom's worth of belongings: a mattress set, dresser, small desk, several boxes, and maybe even a bicycle or two. It’s also a solid option for small business owners who need to store documents, extra inventory, or seasonal signage.
10x15 Storage Unit (150 sq ft)
Need to store the contents of a two-bedroom home or apartment? This is your sweet spot. A 10x15 can fit larger furniture like sofas, dining tables, bedroom sets, and major appliances like a washer and dryer. It’s a great option if you're in between moves, downsizing, or even renovating a portion of your home and need to keep things out of the way but accessible.
10x20 Storage Unit (200 sq ft)
Now we’re talking serious space. A 10x20 is roughly the size of a one-car garage and can easily fit the contents of a three- to four-bedroom house. Sectional sofas, refrigerators, big screen TVs, workout equipment, and large boxes are no problem here. It’s also great for small contractors or businesses with larger inventory and equipment to store securely.
Common Mistakes to Avoid When Estimating Space
One of the biggest pitfalls when choosing a storage unit is underestimating how much space your things really take up. Here are some tips to help avoid common sizing mistakes:
- Not accounting for walkways: You may technically be able to stack everything into a small unit, but if you can't reach the back without unloading everything, it's not functional. Leave space to move.
- Forgetting the awkward items: Bicycles, ladders, odd-shaped furniture, and floor lamps can take up more space than you think.
- Improper stacking: Boxes and furniture can only be stacked so high before it becomes unstable or unsafe. That’s why a slightly larger unit can often save you time, hassle, and future injury.
- Ignoring vertical space: Make sure you're using all the vertical height in the unit, especially if you’re organizing for long-term storage.
When to Upsize or Downsize Your Storage Unit
Life changes—and so do your storage needs. Here’s when it might be time to switch things up:
- Upsize if you're growing a business, accumulating seasonal gear, or adding to your stored inventory. A 10x20 or even a 10x30 could make managing your space much more efficient.
- Downsize when decluttering or after you’ve moved most items back into your home or office. Many renters start big during a move and scale back once they’re settled.
- Evaluate monthly: If your situation has changed—a new lease, a home renovation wrapping up, or even selling stored items—it might be time to reassess and find a better size fit.
