Moving can be one of life’s most exciting, yet simultaneously daunting, adventures. Among the myriad decisions you’ll face, selecting the right moving equipment stands out as crucial. For many, U-Haul trailers offer a cost-effective and flexible solution, but the sheer variety of sizes can leave even seasoned movers scratching their heads.

As an expert blogger and professional SEO content writer, I’ve spent years analyzing what makes a smooth move. Based on my experience, a common pitfall is underestimating your needs or simply picking the first trailer that looks "about right." This article aims to be your definitive resource, a pillar content piece that demystifies U-Haul trailer sizes, ensuring you choose the perfect fit for a stress-free journey.

The Ultimate Guide to U-Haul Trailer Sizes: Choosing the Perfect Fit for Your Move

We’ll dive deep into each trailer type, exploring their dimensions, capacities, ideal uses, and essential towing considerations. By the end, you’ll possess the knowledge to confidently select a U-Haul trailer that meets your specific requirements, helping you save time, money, and headaches.

Why Choosing the Right U-Haul Trailer Size Matters

Selecting the correct U-Haul trailer isn’t just about fitting your belongings; it’s about safety, efficiency, and cost. An overloaded trailer is a serious safety hazard, while an oversized one means wasted fuel and a more challenging towing experience. Conversely, a trailer that’s too small could force multiple trips or leave items behind.

Pro tips from us: Always err on the side of slightly larger if you’re truly on the fence, but don’t go overboard. The goal is efficiency and safety, not excess. Let’s explore the various options U-Haul provides to help you make an informed decision.

Understanding U-Haul Trailer Categories

U-Haul categorizes its trailers into three main types, each designed for distinct purposes. Knowing these categories is your first step toward narrowing down your choices. We’ll cover enclosed cargo trailers, open utility trailers, and specialized car trailers.

Each category serves a unique function, from protecting your household goods from the elements to transporting heavy machinery or vehicles. Understanding these distinctions will significantly streamline your decision-making process.

1. U-Haul Enclosed Cargo Trailers: Protecting Your Valuables

Enclosed cargo trailers are the most popular choice for household moves, offering complete protection from weather and road debris. They come in several sizes, providing varying cubic footage to accommodate different amounts of belongings. These trailers are ideal for furniture, boxes, and items that need to stay dry and secure.

Common mistakes to avoid here are assuming all your items will fit without proper measurement. Always calculate the cubic footage of your belongings if you can, or at least visualize them fitting into the trailer’s dimensions.

a. The Compact Companion: 4’x6′ U-Haul Cargo Trailer

This is U-Haul’s smallest enclosed trailer, perfect for minor moves or extra storage capacity. Don’t let its size fool you; it’s incredibly versatile for specific scenarios.

• Dimensions: Approximately 4 feet wide by 6 feet long, with an internal height of about 4.5 feet.
• Capacity: Roughly 80-85 cubic feet. It can typically hold up to 1,600 lbs of cargo.
• Ideal Use Cases:
  • Studio Apartment Moves: Great for a few boxes, a small desk, and a chair.
  • College Dorm Room: Easily transports mini-fridges, personal belongings, and small furniture.
  • Small Hauls: Perfect for hauling gardening equipment, tools, or small business inventory.
  • Extra Luggage: When your car is packed full but you still have a few bags left.
• Towing Requirements: Generally requires a vehicle with a Class I or II hitch. It’s light enough for most cars, SUVs, and trucks.
• Pro Tip: This trailer is incredibly easy to maneuver, even for novice towers. However, ensure your vehicle has the correct hitch and wiring.

b. The Versatile Performer: 5’x8′ U-Haul Cargo Trailer

The 5’x8′ trailer is a perennial favorite, striking an excellent balance between capacity and towability. It’s often the go-to for smaller apartments or significant decluttering projects.

• Dimensions: Approximately 5 feet wide by 8 feet long, with an internal height of about 5.5 feet.
• Capacity: Around 200-210 cubic feet, capable of holding up to 1,800 lbs.
• Ideal Use Cases:
  • 1-Bedroom Apartment: Can typically accommodate a queen-size bed, dresser, sofa, and several boxes.
  • Small Office Move: Suitable for desks, filing cabinets, and office supplies.
  • Appliance Transport: Fits most standard refrigerators or washing machines.
  • DIY Projects: Great for picking up lumber, large tools, or construction materials securely.
• Towing Requirements: Usually needs a Class II or III hitch. Most SUVs, pickup trucks, and some larger sedans can tow it comfortably.

  • Estate Clear-Outs: When you need to transport a sizable amount of household goods.
• Towing Requirements: A Class III hitch is generally recommended. Pickup trucks and larger SUVs are ideal towing vehicles.
• Pro Tip: The added length can make backing up slightly more challenging for beginners. Practice in an empty parking lot if you’re new to towing this size.

d. The Spacious Solution: 6’x12′ U-Haul Cargo Trailer

This is U-Haul’s largest enclosed cargo trailer, designed for substantial moves. It offers ample space for larger homes or extensive hauling needs. This trailer is often paired with a pickup truck or a robust SUV.

• Dimensions: Approximately 6 feet wide by 12 feet long, with an internal height of about 6.5 feet.

• Common Mistake: Underestimating the impact of wind resistance on fuel economy and vehicle handling, especially with a trailer this size. Always drive cautiously and maintain a safe speed.

2. U-Haul Open Utility Trailers: For the Bulky and the Dirty

Utility trailers are open-air options, perfect for items that don’t need protection from the elements, are awkwardly shaped, or are simply too dirty for an enclosed space. They are often used for landscaping projects, construction materials, or vehicle parts.

From years of observing various moving scenarios, I’ve seen these trailers save the day for everything from mulch runs to motorcycle transport. Always ensure your load is properly secured and covered if necessary.

a. The Handy Hauler: 4’x7′ U-Haul Utility Trailer

This small, open utility trailer is incredibly practical for quick trips and smaller, rugged items. It’s lightweight and easy to maneuver.

• Dimensions: Approximately 4 feet wide by 7 feet long.
• Capacity: Can typically handle up to 1,620 lbs.
• Ideal Use Cases:

c. The Ramp Advantage: 5’x9′ U-Haul Utility Trailer with Ramp

The integrated ramp is the standout feature of this trailer, making loading and unloading incredibly easy for heavy or wheeled items. This trailer is a lifesaver for specific transport needs.

• Dimensions: Approximately 5 feet wide by 9 feet long, featuring a built-in ramp.
• Capacity: Can hold up to 1,650 lbs.
• Ideal Use Cases:
  • Motorcycles/ATVs: The ramp makes loading these vehicles straightforward and safe.

  • Large Equipment: Moving small tractors, construction machinery, or multiple large appliances.
  • Major Debris Removal: Excellent for clearing out large amounts of construction or yard waste.
• Towing Requirements: Requires a vehicle with a Class III hitch and a high towing capacity. Full-size pickup trucks are essential here.
• Common Mistake: Forgetting that an open trailer’s load is exposed. Plan for weather conditions and secure everything tightly to prevent items from flying out.

3. U-Haul Car Trailers: Transporting Your Vehicle

U-Haul also provides specialized trailers for transporting vehicles, which are indispensable for long-distance moves or when a vehicle is non-operable. These fall into two main categories: auto transports and tow dollies. Having helped countless movers, I can confirm these are invaluable for specific situations.

a. The Full Solution: U-Haul Auto Transport

The auto transport trailer is a full-sized car hauler, designed to carry your entire vehicle off the ground. It’s the safest option for long distances or valuable vehicles.

• Dimensions: Large enough to accommodate most cars, SUVs, and light trucks. The ramps and platforms are adjustable.
• Capacity: Can typically handle vehicles weighing up to 5,290 lbs.
• Ideal Use Cases:
  • Long-Distance Vehicle Relocation: Provides maximum protection for your car.
  • Non-Operable Vehicles: Safely moves cars that cannot be driven.
  • Classic or Luxury Cars: Keeps mileage off the vehicle and protects it from road wear.
• Towing Requirements: Requires a heavy-duty towing vehicle (often a full-size pickup truck or large SUV) with a Class III or IV hitch and significant towing capacity (typically over 6,000 lbs). The towing vehicle must be substantially heavier than the vehicle being transported on the trailer.
• Pro Tip: Always double-check your vehicle’s tie-down points and ensure the car is perfectly centered and secured before driving.

b. The Economical Choice: U-Haul Tow Dolly

A tow dolly lifts only the front wheels of your vehicle off the ground, allowing the rear wheels to roll freely. It’s a more economical and lighter option than an auto transport.

• Dimensions: Compact, designed to fit the front wheels of most cars and small SUVs.
• Capacity: Can transport vehicles weighing up to 3,900 lbs.
• Ideal Use Cases:
  • Shorter-Distance Moves: Good for moves where driving the towed vehicle for long distances is not ideal.
  • Front-Wheel Drive Vehicles: Most suitable for FWD vehicles.
  • Budget-Conscious Movers: Generally less expensive to rent than an auto transport.
• Towing Requirements: Requires a towing vehicle with a Class II or III hitch. The towing vehicle must weigh at least 750 lbs more than the vehicle being towed.
• Common Mistake: Using a tow dolly for rear-wheel drive (RWD) or all-wheel drive (AWD) vehicles without disconnecting the driveshaft. This can cause severe transmission damage. Always consult your vehicle’s owner’s manual!

Choosing the Right U-Haul Trailer: A Step-by-Step Guide

Now that you’re familiar with the various U-Haul trailer sizes, let’s put that knowledge into action. Making an informed decision involves more than just guessing. Here’s a structured approach:

1. Inventory Your Belongings and Estimate Volume/Weight

• List Everything: Go room by room and list every item you plan to move. Don’t forget garage, attic, and basement items.
• Categorize: Group items into boxes, furniture, appliances, and unique items.
• Estimate Space: Based on your list, visualize how much space these items would take up. For a more precise estimate, you can use online cubic foot calculators or U-Haul’s own sizing guides (e.g., a studio often needs a 5×8, a 1-bedroom a 5×10, etc.). Remember that the actual usable space in a trailer is less than its stated dimensions due to irregular shapes and loading challenges.
• Estimate Weight: While U-Haul trailers are designed for specific weight capacities, it’s wise to consider the heaviest items (e.g., appliances, safes, heavy furniture) to ensure you don’t exceed limits.

2. Assess Your Towing Vehicle’s Capabilities

This is arguably the most critical step for safety. Common mistakes here lead to dangerous situations.

• Check Your Owner’s Manual: Locate your vehicle’s Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR), and most importantly, its maximum towing capacity.
• Hitch Class: Determine the class of hitch installed on your vehicle (Class I, II, III, IV). U-Haul will match the trailer to your hitch class.
• Transmission Type: Automatic transmissions typically handle towing better, but manual transmissions can tow if properly geared.
• Vehicle Weight: For car trailers, your towing vehicle must often be significantly heavier than the vehicle being towed.

Pro Tip: Never guess your towing capacity. An overloaded vehicle or trailer can lead to loss of control, brake failure, and severe accidents. If in doubt, contact your vehicle manufacturer or a certified mechanic. You can also refer to external resources like this comprehensive guide on understanding towing capacity: .

3. Match Your Needs to U-Haul’s Offerings

With your inventory and towing capacity in hand, cross-reference with the detailed trailer information provided above.

• Household Goods: For most moves, an enclosed cargo trailer is best. Choose the size that comfortably fits your estimated volume.
• Bulky/Outdoor Items: Utility trailers are ideal for items like lawnmowers, building materials, or even ATVs. Consider a ramped trailer for easy loading.
• Vehicle Transport: If you’re moving a car, decide between an auto transport for maximum safety and convenience, or a tow dolly for shorter distances and specific vehicle types (FWD).

4. Consider the Distance and Your Driving Experience

• Long Distances: For cross-country moves, an enclosed trailer offers superior protection. For car transport, an auto transport is generally safer and causes less wear on the towed vehicle.
• Driving Experience: If you’re new to towing, start with a smaller trailer. Larger trailers, especially car transports, require more experience, wider turns, and longer braking distances.

5. Don’t Forget Accessories and Safety Checks

• Tie-Downs: Essential for securing any load, especially in utility trailers.
• Moving Blankets/Pads: Protect furniture and fragile items.
• Locks: Secure your enclosed trailer.
• Pre-Trip Inspection: Before you leave, check tire pressure (trailer and tow vehicle), lights, turn signals, brake lights, and hitch connection. This is a non-negotiable step based on my experience.

Safety Tips for Towing U-Haul Trailers

Towing a trailer introduces new dynamics to driving. Safety should always be your top priority.

1. Load Distribution: Always load heavier items first, over the trailer’s axle or slightly forward of it. Never put too much weight in the rear, as this can cause dangerous "trailer sway."
2. Secure Your Load: Use appropriate tie-downs, straps, or ropes. For open trailers, a tarp can protect items and prevent anything from flying out.
3. Hitch and Safety Chains: Ensure the trailer is correctly hitched and the safety chains are crossed under the tongue, providing backup if the hitch fails.
4. Pre-Trip Inspection: Before every leg of your journey, check tire pressure (including the spare), lights, brakes, and all connections.
5. Adjust Your Driving:
   • Slower Speeds: Drive below the posted speed limit, especially on highways or winding roads. U-Haul trailers often have a maximum recommended speed.
   • Wider Turns: Trailers cut corners. Take wider turns to avoid hitting curbs or other obstacles.
   • Increased Braking Distance: Your stopping distance will be significantly longer. Maintain extra space between your vehicle and others.
   • Mirror Adjustment: Adjust your side mirrors to get a clear view of the trailer and the lanes beside you.
   • Avoid Sudden Movements: Smooth acceleration, braking, and steering are crucial to prevent trailer sway.
6. Be Mindful of Weather: High winds, heavy rain, or icy conditions dramatically increase the risk when towing. If conditions are severe, pull over and wait it out.

Cost Considerations

While this article focuses on sizes, it’s worth briefly mentioning that rental costs vary by trailer size, rental duration, and distance. Larger trailers typically cost more. Don’t forget to factor in potential insurance options and the impact on your fuel efficiency, as towing always consumes more gas.

Conclusion: Your Smart Move Starts Here

Choosing the right U-Haul trailer size is a foundational step toward a successful and stress-free move. By carefully assessing your belongings, understanding your towing vehicle’s capabilities, and familiarizing yourself with the various U-Haul trailer options, you can make an informed decision that ensures safety, efficiency, and peace of mind.

Remember, common mistakes are easily avoided with a little planning and attention to detail. Don’t rush the selection process. Take the time to measure, calculate, and verify. With this comprehensive guide in hand, you are now equipped to choose the perfect U-Haul trailer for your next adventure. Happy moving!
