Which Size Fits Your Needs?

Here’s a simple breakdown of how different-sized units are typically used, so you can figure out which one might work best for you.

10' × 5' (Small)

• This is the smallest option Deer Run Storage provides.

• Ideal for storing a few boxes, seasonal items (like camping gear or holiday decorations), or small furniture pieces.

• If you're just clearing out a closet or storing off-season clothes, this unit is very efficient.

10' × 10' (Medium)

• This is a very flexible, “go-to” size.

• Perfect for a one-bedroom apartment’s worth of stuff: small couch, table & chairs, a mattress set, and lots of boxes.

• Also great for business inventory or supplies.

10' × 15' (Bigger Medium)

• More room than the 10' × 10', so you can store bulkier furniture — maybe a bookshelf, larger appliances, or multiple mattresses.

• Good for small apartment moves or people who want a little breathing room for their things.

10' × 20' (Large)

• This size can hold contents from a larger apartment or a small house.

• Think: several large furniture pieces, multiple boxes, and maybe even a couple of big appliances.

• A very practical choice if you're relocating or renovating.

10' × 25' (Two-Door)

• Same footprint as the 10' × 25' but with doors on both ends.

• Extremely useful if you want to drive straight through or access your belongings from either side.

• Great when you have big or long items — it gives you flexibility and ease of loading.

30' × 10'

• The longest unit available; this is almost like a small garage.

• Excellent for storing bulky furniture, large home items, or even tools / large equipment.

• Can fit large appliances, sofas, and other sizable belongings without feeling cramped.

12' × 39' RV Stall

• Specifically built for recreational vehicles.

• Offers coverage, protection from weather, lighting, and power.

• Ideal for RV owners who want a long-term, safe spot for their vehicle.

How to Choose the Right Unit for You

Take inventory of your items.

List out what you plan to store — boxes, furniture, appliances, or maybe a vehicle. This will help you estimate how much space you need.

Be realistic about future needs.

If you think you might add more things later (or want some space to walk around in your unit), it’s better to lean toward a slightly larger size.

Think about access.

Do you want drive-up access (so you can pull your car right up)? At Deer Run, that’s possible with their units.

Also, if you want to access items from both ends, the 2-door 10’ × 25’ unit is a smart pick.

Consider how often you'll go in.

Since Deer Run Storage offers 24-hour access, you can drop by whenever needed. This makes it easier to go for a slightly bigger unit if you want flexibility rather than squeeze into the smallest one.

Budget matters.

While prices vary, Deer Run’s smaller units (like the 10' × 5’) are more affordable, and larger ones obviously cost more. You’ll want to balance your space needs with how much you’re okay paying monthly.

Why Deer Run Storage Is a Good Choice

• Secure & Monitored: The facility has digital video surveillance to keep your items safe.

• Always Accessible: With 24-hour access, you're not tied down to office hours.

• Easy Online Booking: Rent your unit through Deer Run’s online portal — no need to call if you don’t want to.

• Drive-Up Doors: Many units let you load/unload directly from your vehicle — super convenient.

• Two-Building Layout: The facility is split into Building A and Building B, with unit numbers tied to building letters (like A25 or B44) for easier navigation.

Final Tip

If you’re unsure which unit size to pick, here’s a safe bet: go one size up from what you think you need. Having a little extra space means you aren't cramming things in, and you won't stress about whether something “will fit.” And with Deer Run’s flexible, reliable storage options, that extra room may feel well worth it.
