How to Choose the Right Size Storage Unit for Your Needs

When faced with the need for extra space, whether it’s for storing seasonal items, decluttering your home, or safeguarding belongings during a move, a storage unit can be a practical solution. However, one of the big questions people face is how to choose the right size storage unit. Picking the right size is crucial—not only for ensuring that your items fit but also for avoiding unnecessary costs on a unit that’s too large.

This guide will walk you through everything you need to know to make the right decision.

Why Choosing the Right Size Matters

Selecting the ideal storage unit size has two main benefits:

  • Cost-Effectiveness: Units come in a range of sizes and prices. Choosing one that’s too large will mean paying for space you don’t need. On the other hand, if you pick something too small, you may need to rent an additional unit—which increases costs.
  • Convenience: The right-sized unit ensures all your belongings fit while leaving enough space to easily organize and access them as needed.

To make an informed decision, start by determining what you’ll store and how much space you’ll realistically need.

Common Storage Unit Sizes & What They Fit

Storage units are typically categorized by size, ranging from small closet-sized units to much larger warehouse-style spaces. Here’s a breakdown:

1. Small Storage Units (5’x5′ and 5’x10′)

  • What fits: These are ideal for small furniture items, boxes, holiday decorations, or seasonal clothes. Think of it as similar to a small closet or half of a walk-in closet.
  • Best for: College students, individuals with a few belongings, or those looking to store small miscellaneous items.

2. Medium Storage Units (10’x10′ and 10’x15′)

  • What fits: These can hold the contents of a one- or two-bedroom apartment, including furniture, appliances, and boxes. Think of it as the size of a typical bedroom.
  • Best for: Small families, people moving into or out of an apartment, or those in need of storage for moderate amounts of household goods.

3. Large Storage Units (10’x20′ and 10’x30′)

  • What fits: These are big enough to store the contents of a multi-bedroom house, including larger furniture pieces, appliances, or even vehicles (e.g., cars, small boats).
  • Best for: Homeowners during a big renovation, families relocating, or business owners storing inventory.

How to Determine the Right Size for You

Step 1: Take an Inventory of Your Items

Start by listing everything you plan to store. Group similar items together to get a sense of how much space they’ll require. For example, list furniture, boxes, and other items separately.

Step 2: Measure Larger Items

Use a tape measure to determine the height, width, and depth of your larger furniture or appliances. Keep in mind that some items, like couches, may be more space-efficient if stored upright.

Step 3: Consider Future Additions

Are you storing for the short term, or do you plan on adding more items over time? If you anticipate needing more space in the near future, size up slightly. This ensures you won’t need to rent an additional unit later on.

Step 4: Think About Accessibility

Will you need to access your items frequently? If so, it’s important to leave some room to walk or create aisles within your unit. This will make retrieving items easier.

Helpful Tips for Making the Most of Your Storage Unit

  • Organize Strategically: Place frequently used items near the front of the unit and less important items toward the back.
  • Use Vertical Space: Stack boxes and use shelves to maximize the height of your unit. Just make sure heavy items are at the bottom and lighter ones on top.
  • Label Everything: Clearly label each box so you know what’s inside without needing to open them all.
  • Consider Climate-Controlled Units: If you’re storing temperature-sensitive items like electronics, antiques, or artwork, a climate-controlled unit is a must.

Final Thoughts

Choosing the perfect storage unit size doesn’t have to be daunting. By knowing what you need to store, how much space those items require, and how to organize efficiently, you can save both money and hassle. Take your time, measure accurately, and don’t hesitate to upsize slightly if you think you’ll need additional room in the future.
