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're storing a compact car, full-size SUV, or specialty vehicle, understanding your options will help you make the best decision for your needs and budget.

Vehicle storage has become increasingly popular for car enthusiasts, seasonal drivers, and anyone needing secure parking solutions. From protecting classic cars during winter months to storing daily drivers during extended travel, the right storage unit provides peace of mind and protects your investment.


Key Factors to Consider Before Choosing Storage

Before diving into specific unit sizes, several important factors will influence your decision about what size storage unit you need for your car.

  • Vehicle dimensions are your starting point. Measure your car's length, width, and height, including any accessories like roof racks, side mirrors, or hitches. The average car measures about 14.7 feet in length and 5.8 feet in width, but your specific vehicle may vary significantly.
  • Storage type preferences also matter. Indoor storage offers maximum protection from weather and theft but costs more than outdoor alternatives. Covered outdoor storage provides a middle ground, protecting from sun and precipitation while remaining more affordable than fully enclosed units.
  • Additional storage needs can affect your unit size choice. Do you plan to store car care supplies, seasonal tires, or other automotive accessories alongside your vehicle? Factor in extra space for these items when making your selection.

Storage Unit Size Guide by Vehicle Type

Motorcycles and ATVs

Recommended size: 5×10 or 10×10
Motorcycles and ATVs require the least storage space. A 5×10 unit accommodates most standard motorcycles comfortably, while larger bikes or three-wheelers may need a 10×10 unit. These smaller units are cost-effective and provide adequate protection for your recreational vehicles.

Compact Cars

Recommended size: 10×15
Compact cars fit well in 10×15 storage units. This size works perfectly for vehicles like:

  • Mini Cooper (12.6 feet long)
  • Honda Fit (13.3 feet long)
  • Volkswagen Golf (13.8 feet long)
  • Toyota Corolla (14.2 feet long)
  • Ford Fiesta (14.5 feet long)

A 10×15 unit provides enough space for your compact car plus room for maneuvering and storing a few additional items like cleaning supplies or spare parts.

Sedans, Small SUVs, and Trucks

Recommended size: 10×20
Mid-size vehicles typically require 10×20 storage units. This size accommodates:

  • Honda Accord sedan (15.8 feet long)
  • Nissan Rogue crossover (15.4 feet long)
  • Ford Explorer SUV (16.5 feet long)
  • Chrysler Pacifica minivan (17.0 feet long)
  • Toyota Tundra pickup truck (19.0 feet long)

The 10×20 size offers sufficient space for most family vehicles while leaving room for additional storage or easier access around the vehicle.

Large Trucks and SUVs

Recommended size: 10×25 or 10×30
Larger vehicles need more substantial storage space. Consider these units 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 larger units not only accommodate oversized vehicles but also provide extra space for tools, equipment, or other storage needs.


Preparing Your Vehicle for Storage

Proper preparation ensures your car remains in excellent condition throughout its storage period.

  • Cleaning and waxing should be your first step. Thoroughly wash your car's exterior and apply a fresh coat of wax to protect the paint. Clean the interior completely, removing any food particles or debris that could attract pests or create odors.
  • Essential maintenance tasks include changing the engine oil, topping off all fluids (brake fluid, antifreeze, windshield washer fluid), and inflating tires to the recommended pressure. Fill your gas tank completely and consider adding a fuel stabilizer to prevent fuel degradation.
  • Battery care is crucial for longer storage periods. Disconnect the battery terminals to prevent drainage, or consider using a battery tender to maintain charge levels. This simple step can save you from dealing with a dead battery when you're ready to drive again.
  • Protective measures like using a car cover provide additional protection from dust, moisture, and potential scratches. Choose a breathable cover that fits your vehicle properly to prevent condensation buildup.
  • Preventing tire damage is important for extended storage. Consider using jack stands to lift the vehicle slightly, preventing flat spots from developing on tires. If using jack stands isn't practical, move the car periodically if possible.

Types of Vehicle Storage Options

Indoor Storage

Indoor vehicle storage provides the highest level of protection. These units shield your car from weather extremes, UV rays, theft, and vandalism. Climate-controlled indoor units maintain consistent temperature and humidity levels, making them ideal for classic cars or luxury vehicles.

Indoor storage typically costs more than outdoor alternatives but offers superior protection for valuable vehicles. The enclosed environment also provides privacy and security for your automotive investments.

Covered Outdoor Storage

Covered storage offers a compromise between protection and cost. These spaces feature canopies or carports that protect from sun, rain, and snow while allowing natural air circulation.

This option works well for everyday vehicles that need protection from the elements but don't require the full security of indoor storage. Covered spaces typically cost less than indoor units while providing substantial weather protection.

Outdoor Storage

Outdoor vehicle storage is the most economical option, consisting of designated parking spaces within fenced storage facilities. While your vehicle remains exposed to weather conditions, these facilities typically offer security features like gated access, surveillance cameras, and regular patrols.

Outdoor storage works well for vehicles designed to withstand weather exposure and for short-term storage needs. Consider using a car cover for additional protection in outdoor storage situations.


Additional Storage Considerations

  • Facility requirements typically include providing photo identification, proof of insurance, vehicle registration, and license plate information. Most facilities require vehicles to be in working condition and properly registered.
  • Security features vary by location but often include gated access with personalized codes, security cameras, adequate lighting, and on-site management during business hours. Research these features when comparing facilities to ensure your vehicle's safety.
  • Access policies differ among storage providers. Some offer 24/7 access while others have specific hours. Consider your needs for accessing your vehicle when choosing a facility.
  • Insurance considerations remain important even in storage. Maintain your vehicle insurance throughout the storage period, and verify whether your policy covers storage-related incidents. Some storage facilities also offer additional insurance options.

Making the Right Choice for Your Vehicle

Selecting the appropriate storage unit size for your car requires balancing your vehicle's dimensions, protection needs, and budget considerations. Start by measuring your vehicle carefully, including any accessories or modifications that might affect space requirements.

Consider your storage duration when weighing indoor versus outdoor options. Short-term storage might justify outdoor spaces, while long-term storage often benefits from indoor protection. Factor in your vehicle's value and sentimental importance when making this decision.

Remember that slightly larger units often provide better value through improved accessibility and additional storage space. The extra room makes it easier to walk around your vehicle for inspections and provides space for automotive supplies.

Research multiple storage facilities in your area, comparing prices, security features, and access policies. Read reviews from other customers and visit facilities in person to assess their condition and security measures.

What size storage unit you need for your car ultimately depends on your specific vehicle and requirements, but following these guidelines will help you make an informed decision that protects your automotive investment while meeting your budget needs.
