How Big of a Storage Unit Do I Need? [Size & Price Guide]

Choosing the right unit size is one of the most tricky decisions when renting a storage space. Too small, and you’ll be cramming things in or leaving items behind; too large, and you’ll be wasting money on unused space.

This begs the big question: How big of a storage unit do I need?

As a leading consultant in the self-storage industry, we’ll provide expert guidance on choosing the right unit size when renting storage space. We’ll cover common unit dimensions, their typical costs, and how to estimate the space you’ll require.

What Are the Different Storage Unit Sizes and Prices?

To assess the size of a storage unit you need, you need to understand the size storage unit facilities offer and their corresponding prices.

Let’s break down the options to help you make an informed decision.

Standard Unit Sizes and Costs

Storage unit rentals in the US vary widely based on size and location:

  • Small units, like a 5x5, typically start at around $65 per month. These units are great for storing small items such as boxes or seasonal decorations.

  • Medium-sized units for a small room, such as a 10x10, generally cost more. Expect to spend between $100 and $200 on these unit sizes.

  • For larger storage needs, a 10x20 unit—ideal for the contents of a two-bedroom apartment or large furniture—can cost up to $250 per month.

Note that these prices aren’t fixed; they vary based on various factors discussed below.

What Factors Affect Storage Unit Prices?

Several key factors can significantly influence the cost of renting a storage unit. These include location, climate control features, and extra services offered.

1. The Facility’s Location

Location is one of the primary determinants, with prices varying widely across different states. For example, Oklahoma offers some of the most affordable storage solutions, with average rates of around $61.99 per month. In contrast, Hawaii tends to be the most expensive, with monthly rates averaging $137.12. This variation is often due to the availability of space and the cost of living in these areas.

2. Climate Control Features

Climate control is essential for protecting sensitive items—like electronics or antiques—from extreme temperatures or humidity. While invaluable for preserving your belongings, climate control can typically increase your monthly rental cost by about 10-20%. Seasonality and availability also play a role; demand for storage tends to increase during certain times of the year, like summer (peak moving season), potentially driving up prices.

3. Additional Amenities Offered

Lastly, additional amenities such as 24-hour access, heightened security, or premium locations within the facility (e.g., ground floor or near elevators) can further impact costs. When budgeting for storage, it’s important to consider these variables to accurately estimate your monthly expenses and choose the most suitable option for your needs.

Now that you understand how your storage rental costs can vary depending on these factors, you can go on to calculate the needed space and estimate costs based on your situation.

How to Know the Right Storage Unit Size for Your Needs

You can determine the right storage unit for your valuables by first understanding your storage needs and requirements and then comparing prices across different facilities.

Here is a detailed breakdown:

1. Assess Your Storage Needs

The first step in determining how big a storage unit you need is to take a thorough inventory of your belongings. A two-bedroom house will typically require more storage than a one-bedroom apartment.

If you’re looking to store just a few items from your home, like your dining room set, you’ll need an even smaller space. Similarly, if you need vehicle storage, most standard cars require at least a 10x20 unit.

You may be wondering, how big of a storage unit do I need for a three-bedroom house? Depending on how much you’re storing, you’ll likely need a 10x20 or 10x30 unit. A 10x30 unit can typically accommodate the contents of a three- to five-bedroom house.

2. Calculate and Compare

To get a more precise estimate, calculate the total square footage or cubic footage of the items you plan to store and compare it with the facility’s offerings. Consider choosing between small (25-50 sq ft), medium (75-150 sq ft), or large (200-300 sq ft) storage units based on your calculations.

Remember to research specific unit measurements offered by storage companies to find the best fit. When considering storage unit sizes and prices, it’s wise to compare costs from multiple providers to ensure you’re getting the best deal for your needs.

By following these steps, you’ll be well-equipped to choose the right storage unit size for your specific requirements, avoiding the pitfalls of renting a unit that’s either too small or unnecessarily large.

Frequently Asked Questions

How Do I Figure out How Big a Storage Unit I Need?

To determine the storage unit size you need, measure the length and width of each item you plan to store and calculate the total square footage required. Alternatively, measure one small, medium, and large box, count the number of each box size in your inventory, and estimate based on these measurements.

How Big of a Storage Unit Do I Need for a Car?

For storing a compact car, you’ll need at least a 10x15 storage unit. For medium to large vehicles, consider larger units like 10x20, 10x25, or 10x30 to ensure ample space and easy manoeuvrability.

How Big of a Storage Unit Do I Need for a 3-Bedroom House?

A 3-bedroom house typically requires a storage unit between 120 and 160 square feet. This size accommodates most household items, including patio furniture, major appliances, small furniture, and personal belongings, ensuring everything fits comfortably.

Conclusion

So, How big of a storage unit do you need?

Choosing the right storage unit size doesn’t have to be overwhelming. By taking inventory of your items, measuring larger pieces, and considering how you’ll organize the space, you can confidently select the perfect unit for your needs.

Remember to factor in potential future storage requirements as well. Don’t hesitate to ask the facility staff for guidance—they’re there to help you make the best decision. With the right unit size at a price that fits your budget, you’ll have peace of mind knowing your belongings are secure and accessible whenever you need them.
