What Size Storage Unit Do I Need for a Car?

Choosing the right storage unit size for your car doesn't have to be complicated. Whether you have a compact car, a large SUV, or a classic vehicle you want to protect, understanding your options will help you make the best choice. This guide will answer the question, "What size storage unit do I need for a car?" and provide tips to ensure your vehicle stays safe and secure.

Vehicle storage is a popular solution for car enthusiasts, people who drive seasonally, and anyone needing a secure parking alternative. From protecting a vintage car during the winter to storing a daily driver during long-term travel, the right storage unit offers peace of mind and protects your investment.


Key Factors for Choosing a Car Storage Unit

Before you decide on a specific storage unit size for a car, there are several important factors to consider. Thinking through these points will help you narrow down your options effectively.

  • Vehicle Dimensions: The first step is to measure your car. Note its exact length, width, and height. Remember to include accessories like side mirrors, roof racks, or trailer hitches in your measurements. While the average car is about 15 feet long, sizes vary greatly.
  • Storage Type: Do you need indoor or outdoor storage? Indoor units offer the best protection from weather and theft but are more expensive. Covered outdoor storage is a good middle ground, shielding your vehicle from sun and rain.
  • Extra Space: Do you plan to store other items with your vehicle? If you need room for car care supplies, seasonal tires, or other automotive gear, you will need to factor that into your decision about the storage unit size for a car.

What Size Storage Unit Do I Need for a Car? A Guide by Vehicle Type

Finding the right fit is crucial. Here’s a breakdown of recommended storage unit sizes based on common vehicle types.

Motorcycles and ATVs

  • Recommended Size: 5x10 or 10x10 feet
    A 5x10 unit is usually large enough for a standard motorcycle, while a 10x10 unit can accommodate larger bikes, multiple motorcycles, or ATVs. These smaller units are cost-effective and provide excellent protection for your recreational vehicles.

Compact Cars

  • Recommended Size: 10x15 feet
    A 10x15 storage unit is a great fit for most compact cars. This size works well for vehicles such as:

    • Mini Cooper (12.6 feet long)
    • Honda Fit (13.3 feet long)
    • Toyota Corolla (14.2 feet long)

    This unit size gives you enough space for your car plus a little extra room to walk around and store a few small items.

Sedans, Small SUVs, and Minivans

  • Recommended Size: 10x20 feet
    The most common storage unit size for a car is the 10x20 unit. It’s perfect for most mid-size vehicles, including:

    • Honda Accord sedan (15.8 feet long)
    • Ford Explorer SUV (16.5 feet long)
    • Chrysler Pacifica minivan (17.0 feet long)

    A 10x20 unit is roughly the size of a one-car garage, offering plenty of space for your vehicle while leaving room for easy access.

Large Trucks and SUVs

  • Recommended Size: 10x25 or 10x30 feet
    If you have a larger vehicle, you will need a more substantial storage space. These larger units are ideal for:

    • GMC Sierra 3500 crew cab (21.5 feet long)
    • Ford F-350 crew cab (22.2 feet long)
    • Chevrolet Express cargo van (20.3 feet long)

    These units accommodate oversized vehicles and provide significant extra space for tools, equipment, or other storage needs.


How to Prepare Your Vehicle for Storage

Proper preparation keeps your car in excellent condition while it’s stored. Follow these steps before you park it.

  • Clean and Wax: Wash the exterior and apply a fresh coat of wax to protect the paint. Clean the interior thoroughly, removing any trash or food crumbs that could attract pests.
  • Perform Maintenance: Change the oil, top off all fluids like antifreeze and brake fluid, and inflate the tires to the recommended pressure. Fill the gas tank and add a fuel stabilizer to prevent the fuel from degrading.
  • Care for the Battery: For long-term storage, disconnect the battery to prevent it from draining. Alternatively, you can use a battery tender to maintain its charge.
  • Use a Cover: A breathable car cover adds an extra layer of protection against dust, moisture, and scratches.
  • Protect the Tires: To prevent flat spots from developing on your tires during extended storage, consider using jack stands to lift the vehicle off the ground.

Types of Vehicle Storage Options

When determining what size storage unit you need for a car, you also have to choose the type of storage.

Indoor Storage

Indoor units provide the highest level of protection. They shield your car from extreme weather, UV rays, theft, and vandalism. Climate-controlled options maintain a consistent temperature and humidity, which is ideal for classic, luxury, or other high-value vehicles.

Covered Outdoor Storage

Covered storage is a great balance of protection and cost. These carport-style spaces protect your vehicle from sun, rain, and snow while allowing for natural air circulation. It’s a good choice for daily drivers that need protection from the elements.

Outdoor Storage

Outdoor storage is the most economical option. It consists of a designated parking space within a fenced, secure facility. While exposed to the weather, these lots typically have security features like gated access and surveillance cameras.


Final Considerations for Car Storage

  • Facility Requirements: Most facilities require you to provide a photo ID, proof of insurance, and the vehicle's registration. The car usually needs to be in working condition.
  • Security Features: Look for facilities with gated access, 24/7 security cameras, good lighting, and on-site management. These features are key to your peace of mind.
  • Access Policies: Check the facility's access hours. Some offer 24/7 access, while others have more restricted hours. Choose one that fits your schedule.
  • Insurance: Keep your vehicle insurance active. Verify that your policy covers incidents that may occur while in storage, or ask the facility about their insurance options.

Making the Right Choice for Your Vehicle

Answering "What size storage unit do I need for a car?" involves balancing your vehicle's size, your budget, and your protection needs. Start by measuring your car carefully. Consider how long you plan to store it; short-term storage may be fine for an outdoor space, while long-term storage often warrants indoor protection.

Remember that a slightly larger unit can provide better value by offering easier access and extra room for supplies. Research local storage facilities, compare their prices and security, and read customer reviews. By following these guidelines, you can make an informed decision that protects your vehicle and fits your budget.
