Moving can be one of life’s most challenging yet exciting transitions. Whether you’re relocating across town or embarking on a cross-country adventure, transporting your belongings safely and efficiently is paramount. The right equipment makes all the difference, and for many, a U-Haul cargo trailer is the go-to solution.

However, navigating the various U-Haul trailer sizes and understanding their specific dimensions can feel like a daunting task. Choosing a trailer that’s too small means multiple trips or leaving items behind, while one that’s too large can be difficult to tow and potentially wasteful. This comprehensive guide is designed to be your ultimate resource, breaking down every critical detail about U-Haul cargo trailer dimensions.

The Ultimate Guide to U-Haul Cargo Trailer Dimensions: Choosing Your Perfect Moving Partner

Based on my extensive experience in content creation and understanding user needs in the moving sector, getting these dimensions right is the cornerstone of a stress-free move. We’ll dive deep into each model, offering pro tips, common mistakes to avoid, and everything you need to make an informed decision. Our goal is to empower you to select the perfect enclosed trailer, ensuring your belongings arrive safely and your move is as smooth as possible.

Why Understanding U-Haul Cargo Trailer Dimensions is Crucial for a Smooth Move

Before we delve into the specifics of each U-Haul trailer size, let’s explore why a thorough understanding of these dimensions is not just helpful, but absolutely essential. It’s more than just knowing if your couch will fit; it impacts safety, efficiency, and your wallet.

Avoid Costly Mistakes and Delays:
One of the most common pitfalls movers encounter is underestimating the space needed. A trailer that’s too small means you might have to leave items behind, make multiple trips, or scramble for last-minute solutions, all of which add stress and expense. Conversely, renting a trailer that’s significantly larger than necessary means paying for unused space and potentially dealing with a more challenging towing experience.

Ensure Maximum Safety on the Road:

Proper weight distribution and secure packing are directly tied to the trailer’s interior dimensions and weight capacity. Knowing these limits allows you to load your U-Haul trailer correctly, preventing hazardous shifts in weight during transit. Overloading a trailer or improper weight distribution can lead to dangerous swaying, loss of control, and even accidents, putting your belongings and others at risk.

Optimize Your Packing Strategy:
When you know the exact interior dimensions, including the loading opening dimensions, you can plan your packing strategy meticulously. This foresight helps you decide which items to disassemble, how to stack boxes efficiently, and where to place oddly shaped furniture. It transforms packing from a chaotic scramble into a strategic puzzle, maximizing every cubic foot of space.

Save Time and Money:
Ultimately, understanding U-Haul cargo trailer dimensions translates into significant savings of both time and money. A single, well-planned trip in the perfectly sized trailer eliminates the need for extra fuel, additional rental days, and the potential costs associated with damaged goods or emergency storage. It allows you to move with confidence, knowing you’ve made the smartest choice.

The U-Haul Cargo Trailer Lineup: Your Enclosed Moving Solutions

U-Haul offers a reliable fleet of enclosed cargo trailers designed to protect your belongings from the elements and road debris. These trailers come in distinct sizes, each catering to different moving needs, from small apartment moves to hauling larger household items. They are built for durability and ease of towing, making them a popular choice for DIY movers.

Our focus here is on the primary enclosed cargo trailer options: the 4×8, 5×8, and 6×12 models. While U-Haul also offers utility and car haul trailers, these cargo trailers are specifically designed for secure, weather-protected transport of your household goods. Understanding the nuances of each will guide you to your ideal moving partner.

Let’s break down each model in detail, offering insights that go beyond just the numbers.

Deep Dive: U-Haul 4×8 Cargo Trailer Dimensions

The U-Haul 4×8 cargo trailer is the smallest enclosed option available, often chosen for very compact moves or transporting a few select items. It’s surprisingly versatile for its size, making it a popular choice for dorm room relocations, transporting tools, or clearing out a small storage unit.

This trailer is an excellent solution when you don’t need extensive space but require the security and weather protection an enclosed trailer offers. It’s also one of the easiest U-Haul trailers to tow due to its compact footprint.

Interior Dimensions: Maximizing Your Small Space

Understanding the interior dimensions is key to packing this compact trailer effectively. Every inch counts when space is at a premium.

• Interior Length: Approximately 7′ 11" (95 inches). This length is sufficient for a twin mattress, a few dresser drawers, or a stack of moving boxes.
• Interior Width: Approximately 3′ 11" (47 inches). This width allows for standard moving boxes to be placed side-by-side or a narrow piece of furniture.
• Interior Height: Approximately 4′ 5" (53 inches). While you can’t stand upright, this height accommodates stacked boxes, smaller appliances, or a disassembled desk.

Based on my experience… many people underestimate the usable height. Always measure your tallest item when standing, and then consider if it can be tilted or laid flat. Remember, the wheel wells inside the trailer will slightly reduce usable width at the floor level.

Exterior Dimensions: Navigating Roads and Parking

The exterior dimensions are crucial for understanding how the trailer will handle on the road and in tight spaces. Its compact size is a significant advantage here.

• Overall Length (Hitch to Bumper): Approximately 11′ 11" (143 inches). This length, combined with your vehicle, determines your total rig length.
• Overall Width (Fender to Fender): Approximately 5′ 6" (66 inches). This is only slightly wider than most passenger vehicles, making it easy to maneuver.
• Overall Height: Approximately 6′ 3" (75 inches). This relatively low height is generally not an issue for most overpasses or garages.

Pro tips from us… for city driving, the 4×8 is fantastic because it’s agile and doesn’t significantly impact your turning radius. Always factor in the combined length of your vehicle and trailer, especially when parking or changing lanes.

Loading Opening Dimensions: Getting Your Items Inside

The door opening is a critical measurement, especially for bulkier items. Don’t assume an item that fits the interior width will fit through the door.

• Door Width: Approximately 3′ 2" (38 inches).
• Door Height: Approximately 4′ 1" (49 inches).

Common mistakes to avoid are… forgetting to measure the door opening! A common scenario is having a small dresser or appliance that fits perfectly inside the trailer but is just a hair too wide or tall for the door. Always measure your largest items against these door dimensions first.

Volume Capacity, Max Load Weight, and Towing Requirements

• Volume Capacity: Approximately 142 cubic feet. This is roughly equivalent to a small studio apartment or dorm room’s worth of items.
• Max Load Weight: 1,600 lbs. While this sounds substantial, always be mindful of your items’ collective weight.
• Minimum Towing Vehicle Weight: 2,000 lbs. Your towing vehicle must be at least this heavy for safe towing.
• Hitch Ball Size: 1-7/8" or 2".

This trailer is excellent for local moves, small furniture, boxes, and miscellaneous items. It’s often paired with smaller SUVs or sedans, provided they meet the towing requirements.

Deep Dive: U-Haul 5×8 Cargo Trailer Dimensions

Stepping up from the 4×8, the U-Haul 5×8 cargo trailer offers a significant increase in usable space, making it one of the most popular choices for many movers. It strikes a balance between generous capacity and manageable towing, ideal for small apartments, single rooms, or larger storage unit contents.

This size is frequently rented by those moving out of a one-bedroom apartment or needing to transport several pieces of furniture along with numerous boxes. It provides that crucial extra width and height that the 4×8 might lack for certain items.

Interior Dimensions: Ample Space for Small Apartment Moves

The added width and height in the 5×8 trailer make a noticeable difference in what you can transport. It allows for more versatile packing arrangements.

• Interior Length: Approximately 7′ 11" (95 inches). The length remains similar to the 4×8, perfect for longer items.
• Interior Width: Approximately 4′ 8" (56 inches). This extra width is a game-changer, accommodating larger dressers, loveseats, or wider appliances. You can often fit two rows of standard moving boxes side-by-side with more ease.
• Interior Height: Approximately 5′ 5" (65 inches). The increased height allows for taller stacks of boxes or upright items that wouldn’t fit in the smaller trailer.

Pro tips from us… utilize the full height by stacking lighter, uniformly sized boxes towards the top. For larger items, try to position them to minimize wasted space around them. Always consider the wheel wells, which reduce floor width slightly.

Exterior Dimensions: Maintaining Maneuverability

Despite its increased interior volume, the 5×8 trailer remains relatively easy to tow and maneuver. It’s still a good option for those less experienced with towing.

• Overall Length (Hitch to Bumper): Approximately 12′ 10" (154 inches). Still manageable, but you’ll notice the extra length compared to the 4×8.
• Overall Width (Fender to Fender): Approximately 6′ 8" (80 inches). This is wider than most cars, so be mindful of lane positioning and narrow passages.
• Overall Height: Approximately 7′ 0" (84 inches). This height is generally fine for most standard clearances.

Based on my experience… the 5×8 is often the sweet spot for first-time trailer towers. It’s large enough to be genuinely useful but not so large that it feels unwieldy. Take wider turns than you normally would, and always check your mirrors.

Loading Opening Dimensions: Wider Access

The wider door opening is a significant advantage for loading larger pieces of furniture, such as a queen-size mattress or a small sofa.

• Door Width: Approximately 4′ 1" (49 inches).
• Door Height: Approximately 4′ 9" (57 inches).

Common mistakes to avoid are… trying to force items through the door. If it’s a tight squeeze, you risk damaging both your item and the trailer. Measure twice, and if it’s still too tight, consider disassembling or looking at the next size up.

Volume Capacity, Max Load Weight, and Towing Requirements

• Volume Capacity: Approximately 200 cubic feet. This is typically enough for a studio or small one-bedroom apartment.
• Max Load Weight: 1,800 lbs. The increased capacity allows for more items or heavier ones.
• Minimum Towing Vehicle Weight: 2,500 lbs. Ensure your vehicle can safely handle this weight.
• Hitch Ball Size: 1-7/8" or 2".

The 5×8 cargo trailer is an excellent general-purpose option, providing a good balance of size, capacity, and ease of towing for a wide range of moving needs.

Deep Dive: U-Haul 6×12 Cargo Trailer Dimensions

The U-Haul 6×12 cargo trailer is the largest enclosed trailer in their standard fleet and is by far the most popular choice for substantial residential moves. It’s the go-to option for one to two-bedroom apartment moves, larger furniture pieces, and comprehensive household goods.

This trailer offers generous space, making it ideal for those who need to transport beds, sofas, appliances, and a significant number of boxes in one go. Its capacity can drastically reduce the number of trips required for your move.

Interior Dimensions: Your Spacious Moving Solution

The interior of the 6×12 provides ample room, allowing for more strategic packing and fitting larger items without extensive disassembly.

• Interior Length: Approximately 11′ 11" (143 inches). This length can easily accommodate a king-size mattress, a full-length sofa, or several large appliances.
• Interior Width: Approximately 6′ 0" (72 inches). The full 6-foot width is incredibly versatile, allowing for multiple items side-by-side or even turning larger furniture sideways.
• Interior Height: Approximately 5′ 5" (65 inches). While you still can’t stand upright, this height is sufficient for stacking numerous boxes and taller furniture items.

Pro tips from us… when loading, place heavier items over the trailer’s axle for optimal weight distribution. Utilize moving blankets and tie-downs to secure items, preventing shifting during transit. For a deeper dive into U-Haul’s rental policies and packing strategies, check out our guide on .

Exterior Dimensions: A Larger Presence on the Road

The 6×12 is a substantial trailer, and its exterior dimensions reflect that. While still towable by many vehicles, it requires more attention and experience.

• Overall Length (Hitch to Bumper): Approximately 15′ 11" (191 inches). This significantly increases your total vehicle length, requiring extra caution.
• Overall Width (Fender to Fender): Approximately 8′ 0" (96 inches). This width will be considerably wider than your towing vehicle, necessitating wider turns and careful lane changes.
• Overall Height: Approximately 7′ 0" (84 inches). Similar to the 5×8, this height is generally acceptable for most clearances.

Based on my experience… towing a 6×12 requires a confident driver and a capable vehicle. Always practice turning and backing up in an empty parking lot before hitting the road. The increased width means you’ll need to pay close attention to side mirrors.

Loading Opening Dimensions: Unrestricted Access

The large door opening is a major advantage, making it easier to load bulky and oversized items that would struggle to fit into smaller trailers.

• Door Width: Approximately 5′ 0" (60 inches).
• Door Height: Approximately 4′ 9" (57 inches).

Common mistakes to avoid are… thinking that because the door is wide, you don’t need to measure your items. Always confirm that your largest pieces of furniture, like a refrigerator or a large armoire, will clear the height and width of the door opening.

Volume Capacity, Max Load Weight, and Towing Requirements

• Volume Capacity: Approximately 396 cubic feet. This capacity is typically suitable for a 1-2 bedroom apartment or small house.
• Max Load Weight: 2,470 lbs. This substantial weight capacity allows for heavy furniture and numerous boxes.
• Minimum Towing Vehicle Weight: 3,500 lbs. A robust SUV or light truck is usually required for safe towing.
• Hitch Ball Size: 2".

The 6×12 cargo trailer is the workhorse of U-Haul’s enclosed trailer fleet, providing the most space and weight capacity for those with significant moving needs.

Beyond Dimensions: Crucial Considerations for Your U-Haul Trailer Rental

While knowing the exact U-Haul cargo trailer dimensions is paramount, your successful rental and move depend on several other critical factors. These considerations ensure safety, compliance, and a smooth experience from start to finish.

Towing Vehicle Requirements: Don’t Overlook Your Ride

Your towing vehicle is just as important as the trailer itself. U-Haul has strict requirements to ensure safety, and you must adhere to them.

• Minimum Vehicle Weight: Each trailer size has a minimum curb weight requirement for the towing vehicle. This isn’t arbitrary; it’s about stability and control. Your vehicle must be heavier than the loaded trailer to prevent sway and maintain control.
• Hitch Ball Size: U-Haul trailers use either a 1-7/8" or 2" hitch ball. Ensure your hitch ball matches the trailer’s coupler size.
• Wiring Harness: Your vehicle must have a functional 4-way flat light connector to power the trailer’s brake lights, turn signals, and running lights. This is a non-negotiable safety feature.
• Towing Capacity of Your Vehicle: Critically, your vehicle’s manufacturer-specified towing capacity must exceed the gross weight of the loaded trailer. This is often found in your vehicle’s owner’s manual.
• Pro tips: Always consult your vehicle’s owner’s manual for its specific towing capacity and requirements. Never guess. If you’re unsure about your vehicle’s towing capabilities, our article on can help.

Loading and Packing Strategies: The Art of Maximizing Space and Safety

Proper loading is essential for both maximizing the utility of your U-Haul trailer and ensuring a safe journey.

• Weight Distribution: Always load about 60% of the weight in the front half of the trailer, closer to the hitch. This creates "tongue weight," which is crucial for preventing dangerous trailer sway.
• Secure Items: Use moving blankets to protect furniture and secure everything with tie-down straps. U-Haul trailers have interior tie-down points for this purpose.
• Heaviest Items First: Place your heaviest, largest items on the floor, over the axle, and centered. Build lighter items around and on top.
• Common mistakes to avoid are… packing too much weight in the back of the trailer (causing fishtailing) or not securing items, which can lead to shifting and damage during turns or braking.

Safety While Towing: Drive Smart, Arrive Safe

Towing a trailer significantly changes your vehicle’s dynamics. Awareness and caution are paramount.

• Pre-Trip Inspection: Before every departure, check tire pressure on both your vehicle and the trailer, ensure lights are working, and confirm the hitch connection is secure.
• Drive Slower: Reduce your speed, especially on highways and winding roads. High speeds increase the risk of sway.
• Wider Turns: Trailers cut corners. Make wider turns than usual to avoid hitting curbs, parked cars, or other obstacles.
• Increased Braking Distance: Your stopping distance will be much longer with a loaded trailer. Maintain extra space between your vehicle and the one in front of you.
• Mirrors: Constantly check your side mirrors to monitor the trailer and surrounding traffic.
• Based on my experience… patience is your best friend when towing. Don’t rush, anticipate traffic, and give yourself plenty of room. If the trailer starts to sway, gently take your foot off the accelerator and hold the steering wheel straight; do not slam on the brakes or swerve.

Understanding U-Haul’s Rental Process: What to Expect

Knowing the logistics of the rental process can prevent last-minute surprises.

• Reservations: Always make a reservation in advance, especially during peak moving seasons. While U-Haul tries to accommodate walk-ins, popular trailer sizes might be unavailable.
• Insurance Options: U-Haul offers various coverage plans for the trailer and your belongings. Review these options carefully to decide what level of protection you need.
• Drop-off Flexibility: U-Haul is known for its convenient one-way rental options, allowing you to pick up a trailer in one location and drop it off at another. Confirm your drop-off location and time when renting.

How to Accurately Measure Your Belongings for a U-Haul Trailer

One of the biggest keys to choosing the right U-Haul cargo trailer is knowing what you’re actually moving. This means more than just a rough estimate; it requires accurate measurements.

1. Inventory Everything: Make a detailed list of every item you plan to put in the trailer. Don’t forget smaller items that can quickly add up in volume.
2. Measure the Largest Items: Focus on the biggest and bulkiest items first – sofas, beds, dressers, appliances, large boxes. Measure their length, width, and height. Note any items that can be disassembled to reduce their footprint.
3. Account for Irregular Shapes: For items that aren’t perfectly rectangular, estimate their maximum dimensions. For example, a uniquely shaped chair should be measured at its widest and tallest points.
4. Visualize Packing: Once you have your measurements, try to visualize how these items will fit together. You can even draw a simple floor plan of the trailer and arrange your items mentally or on paper. This helps you identify potential conflicts or wasted space.
5. Add Buffer Room: Always factor in a little extra space. It’s better to have a slightly larger trailer than one that’s too small. Real-world packing rarely achieves 100% efficiency.

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

With all this information, let’s consolidate it into a clear, actionable plan for selecting your ideal U-Haul trailer.

1. Step 1: Create a Detailed Inventory of Your Belongings. List every single item you intend to move. Don’t forget boxes, plants, and smaller items.
2. Step 2: Measure Your Largest and Bulkiest Items. Pay close attention to sofas, mattresses, appliances, and large furniture. Record their length, width, and height. Also, note their weight if possible.
3. Step 3: Estimate Total Volume and Weight. Based on your inventory and measurements, make an educated guess about the total cubic feet and overall weight of your load. Remember, heavy items add up quickly!
4. Step 4: Match Your Needs to U-Haul Cargo Trailer Dimensions.
   • Small Moves (dorm, studio, few items): Consider the 4×8 trailer (142 cu. ft., 1,600 lbs capacity).
   • Mid-Size Moves (small 1-bedroom, larger furniture): The 5×8 trailer is often perfect (200 cu. ft., 1,800 lbs capacity).
   • Larger Moves (1-2 bedroom apartment, significant furniture): The 6×12 trailer is your best bet (396 cu. ft., 2,470 lbs capacity).
   • Always ensure your largest items will fit through the trailer’s door opening.
5. Step 5: Verify Your Towing Vehicle’s Capability. Confirm your vehicle meets the minimum weight requirements, has the correct hitch ball size, a functional wiring harness, and a towing capacity that exceeds the loaded trailer’s weight. Never compromise on this step for safety.

Frequently Asked Questions (FAQs) About U-Haul Cargo Trailers

Here are answers to some common questions that arise when renting U-Haul cargo trailers.

Q: Can I stand up inside a U-Haul cargo trailer?
A: No, none of the standard U-Haul cargo trailers (4×8, 5×8, 6×12) are tall enough for an average adult to stand upright inside. Their interior heights range from approximately 4′ 5" to 5′ 5".

Q: Do U-Haul cargo trailers have ramps?
A: Typically, no. U-Haul’s enclosed cargo trailers are designed for hand-loading or using a hand truck. Ramps are usually found on U-Haul’s utility trailers (open trailers) or their moving trucks, not the enclosed cargo trailers.

Q: What’s the difference between a U-Haul cargo trailer and a utility trailer?

Q: Are U-Haul trailers safe to tow?
A: Yes, U-Haul trailers are designed and maintained for safety. However, their safety ultimately depends on proper loading, using a capable towing vehicle that meets U-Haul’s requirements, and responsible driving practices by the renter. Always follow all guidelines and safe towing tips.

Q: Can I rent a U-Haul cargo trailer one-way?
A: Yes, U-Haul is renowned for its convenient one-way rental options for all its equipment, including cargo trailers. This allows you to pick up a trailer in one city and drop it off at a different U-Haul location in your destination city.
