The Ultimate U-Haul Trailer Size Guide: Master Your Move with Confidence

Why Choose U-Haul Trailers for Your Hauling Needs?

U-Haul has been a household name in moving for decades, and for good reason. Their extensive network of locations makes pickup and drop-off incredibly convenient, often with one-way rental options available. This flexibility is a huge advantage for cross-country moves.

Beyond convenience, U-Haul trailers offer a robust and affordable alternative to hiring full-service movers or purchasing a trailer outright. They are designed for reliability, providing a secure way to transport everything from household goods to vehicles. Plus, with a wide variety of sizes, there’s almost always a perfect fit for any job.

Understanding the U-Haul Trailer Ecosystem: Types Explained

Before diving into specific dimensions, it’s crucial to understand the three main categories of U-Haul trailers. Each type serves a distinct purpose, designed with specific hauling tasks in mind. Knowing these categories is the first step in narrowing down your options.

1. U-Haul Cargo Trailers (Enclosed)

Cargo trailers are fully enclosed, providing maximum protection for your belongings against weather, road debris, and theft. They are ideal for moving furniture, boxes, and other items that need to stay dry and secure. These trailers typically feature a sturdy frame and a secure latching door.

Based on my experience, these are the go-to choice for most household moves, offering peace of mind that your possessions are safe. Their enclosed nature means you won’t have to worry about tying down tarps or constantly checking on items during long drives.

2. U-Haul Utility Trailers (Open)

Utility trailers are open-top trailers, often equipped with a ramp for easy loading and unloading. They are incredibly versatile, perfect for hauling oddly shaped items, landscaping materials, construction debris, or motorcycles. Their open design allows for greater flexibility with item height and width.

Pro tips from us: While versatile, remember that anything you haul in a utility trailer will be exposed to the elements. Always secure your load properly with straps and consider a tarp for weather protection if needed.

3. U-Haul Car Trailers (Auto Transports & Tow Dollies)

If your mission involves moving a vehicle, U-Haul offers specialized solutions. These trailers are specifically designed to transport cars, trucks, and SUVs safely. They come in two primary forms: the Tow Dolly and the Auto Transport.

We’ve seen countless people successfully move their vehicles using these options. It’s important to match the car trailer to your specific vehicle’s make, model, and weight to ensure a secure tow.

In-Depth U-Haul Cargo Trailer Size Guide (Enclosed)

Now, let’s break down the specific dimensions and ideal uses for each U-Haul enclosed cargo trailer. Remember, these trailers are measured by their interior floor dimensions.

1. 4’x8′ Cargo Trailer

This is U-Haul’s smallest enclosed trailer, surprisingly versatile for its compact size. It’s perfect for smaller tasks where you need to protect your items.

• Interior Dimensions: 8′ L x 4′ W x 4′ H
• Door Opening: 3′ W x 3′ H
• Capacity: 142 cu. ft.
• Max Load: 1,600 lbs
• Tare Weight (empty): 850 lbs

Ideal Use Cases:

• Dorm Room Moves: Easily fits a twin bed, mini-fridge, boxes, and personal items.
• Small Apartment Moves: Suitable for studio apartments or very small 1-bedroom units with minimal furniture.
• Extra Storage: Transporting seasonal decorations, gardening equipment, or overflow from a garage.
• Errands & Deliveries: Perfect for picking up large purchases like appliances or furniture from a store.

Expert Insight: Based on my experience, the 4’x8′ is often underestimated. It’s a fantastic choice if you’re just moving boxes and a few smaller pieces of furniture. However, be mindful of the 4-foot height limit for taller items.

2. 5’x8′ Cargo Trailer

A step up in size, the 5’x8′ is one of the most popular choices for general hauling. It offers a good balance of capacity and maneuverability.

• Interior Dimensions: 8′ L x 4’11" W x 5’5" H
• Door Opening: 4′ W x 4’10" H
• Capacity: 200 cu. ft.
• Max Load: 1,800 lbs
• Tare Weight (empty): 900 lbs

Ideal Use Cases:

• Small Apartment Moves: Comfortable for a 1-bedroom apartment or a larger studio.
• Furniture Transport: Can accommodate a queen-size bed, dresser, and several boxes.
• Equipment Hauling: Perfect for band equipment, landscaping tools, or small business inventory.
• Estate Sales & Auctions: Easily transport multiple finds from a day of shopping.

Common Mistakes to Avoid: Many people try to squeeze a full 2-bedroom apartment into this trailer. While it has decent capacity, it’s generally not enough for larger furniture sets from multiple rooms. Always measure your largest items!

3. 5’x10′ Cargo Trailer

Offering additional length, the 5’x10′ trailer is excellent for slightly larger moves or when you have longer items to transport. It provides more floor space than the 5’x8′.

• Interior Dimensions: 9’10" L x 4’11" W x 5’5" H
• Door Opening: 4′ W x 4’10" H
• Capacity: 268 cu. ft.
• Max Load: 1,860 lbs
• Tare Weight (empty): 1,210 lbs

Ideal Use Cases:

• Medium Apartment Moves: Suitable for a 1-bedroom apartment with a moderate amount of furniture.
• Larger Furniture: Can easily fit longer couches, dining tables, or multiple mattresses.
• Motorcycle Transport: Some smaller motorcycles can be transported securely in this enclosed space.
• Small Business Inventory: Ideal for transporting goods for trade shows or market stalls.

Pro Tip: The extra length makes loading easier for items that might feel cramped in the 5’x8′. However, be mindful that the width and height remain the same as the 5’x8′, so wide or tall items still pose a challenge.

4. 6’x12′ Cargo Trailer

This is U-Haul’s largest enclosed trailer, a powerhouse for more substantial moves. It offers significant capacity, making it a favorite for 1-2 bedroom apartment or small house moves.

• Interior Dimensions: 11’11" L x 5’8" W x 5’6" H
• Door Opening: 5′ W x 5′ H
• Capacity: 396 cu. ft.
• Max Load: 2,500 lbs
• Tare Weight (empty): 1,280 lbs

Ideal Use Cases:

• 1-2 Bedroom Apartment/Small House Moves: Can accommodate most furniture from these types of dwellings.
• Larger Furniture Sets: Easily fits sectionals, king-size beds, multiple dressers, and appliances.
• Business Equipment: Transporting heavy machinery, tools, or extensive inventory.
• Cross-Country Moves: Offers ample space for a significant amount of personal belongings.

Expert Insight: From years of helping people choose the right equipment, the 6’x12′ is often the sweet spot for many residential moves. It provides excellent protection and capacity without requiring an overly large tow vehicle. Always ensure your tow vehicle can handle the combined weight of the trailer and its maximum load.

In-Depth U-Haul Utility Trailer Size Guide (Open)

Utility trailers offer flexibility for open-air hauling, especially for items that are too large, dirty, or oddly shaped for enclosed trailers. They are incredibly useful for DIY projects and yard work.

1. 4’x7′ Utility Trailer

The smallest utility trailer, perfect for quick trips and compact loads. It’s easy to maneuver and suitable for light-duty hauling.

• Deck Dimensions: 7′ L x 4′ W
• Max Load: 1,770 lbs
• Tare Weight (empty): 450 lbs

Ideal Use Cases:

• Yard Waste: Hauling branches, leaves, or bagged clippings to the dump.
• Small Home Improvement Projects: Transporting lumber, bags of concrete, or a few sheets of drywall.
• Motorcycle Transport: Suitable for smaller motorcycles or dirt bikes (ensure proper tie-downs).
• ATV/Quad Transport: Can fit one smaller ATV or quad.

Pro Tip: While small, this trailer requires proper weight distribution. Load heavier items over the axle to maintain stability.

2. 5’x8′ Utility Trailer

A popular mid-sized option, the 5’x8′ utility trailer balances capacity with ease of towing. It’s a workhorse for many homeowners and DIY enthusiasts.

• Deck Dimensions: 8′ L x 5′ W
• Max Load: 1,890 lbs
• Tare Weight (empty): 600 lbs

Ideal Use Cases:

Expert Insight: We’ve seen this trailer used for everything from moving an entire shed’s contents to hauling a riding lawnmower. Its open nature makes loading oversized items surprisingly simple.

3. 5’x9′ Utility Trailer with Ramp

The added ramp feature on this utility trailer makes it exceptionally convenient for rolling items on and off. This is a game-changer for anything with wheels or heavy equipment.

• Deck Dimensions: 9′ L x 5′ W
• Max Load: 1,650 lbs
• Tare Weight (empty): 830 lbs
• Features: Integrated loading ramp

Ideal Use Cases:

• Heavy Equipment: Moving lawnmowers, tillers, pressure washers, or small construction machinery.
• Furniture with Casters: Easier to roll dollies loaded with heavy furniture directly into the trailer.
• Appliance Transport: Simplifying the loading of refrigerators, washers, and dryers.

Common Mistakes to Avoid: While the ramp is a huge benefit, always ensure it’s properly secured before and after use. Also, be mindful of the maximum load capacity, as the ramp itself adds to the trailer’s tare weight.

4. 6’x12′ Utility Trailer

This is U-Haul’s largest open utility trailer, designed for substantial loads. It offers maximum deck space for those big projects.

• Deck Dimensions: 12′ L x 6′ W
• Max Load: 2,110 lbs
• Tare Weight (empty): 1,240 lbs

Ideal Use Cases:

• Large Construction Materials: Hauling long lumber, multiple sheets of plywood, or bulky building supplies.

• Multiple Vehicles: Can often accommodate two motorcycles, multiple ATVs, or a side-by-side UTV.
• Moving Oversized Items: Perfect for hot tubs, large sheds (disassembled), or bulky outdoor equipment.

Pro Tip: This trailer offers significant capacity, but its size also means it requires a capable tow vehicle. Always check your vehicle’s towing specifications carefully before renting.

5. 6’x12′ Utility Trailer with Ramp

Combining the largest utility trailer dimensions with the convenience of a ramp, this is the ultimate choice for heavy and oversized items that need to be rolled on.

• Deck Dimensions: 12′ L x 6′ W
• Max Load: 2,050 lbs
• Tare Weight (empty): 1,300 lbs
• Features: Integrated loading ramp

Ideal Use Cases:

• Large Vehicle Transport: Ideal for multiple motorcycles, larger ATVs, or even small tractors.

• Construction Site Logistics: Efficiently moving materials and equipment on and off a job site.
• Event Planning: Hauling staging, sound equipment, or large props for events.

Expert Insight: From years of handling diverse hauling challenges, I can attest that the 6’x12′ with ramp is an invaluable tool for anyone regularly moving heavy or wheeled items. It significantly reduces physical strain and improves safety during loading.

In-Depth U-Haul Car Trailer Size Guide

Moving a vehicle requires specialized equipment to ensure safety and prevent damage. U-Haul offers two primary options for car transport.

1. U-Haul Tow Dolly

A tow dolly lifts the front two wheels of your towed vehicle off the ground, allowing the rear wheels to remain on the road. It’s a more economical and lighter option compared to an auto transport.

• Max Towing Capacity: 3,000 lbs (vehicle weight)
• Max Tire Width: 79"
• Minimum Tread Width: 40"
• Tare Weight (empty): 590 lbs

Ideal Use Cases:

• Front-Wheel Drive Vehicles: Most suitable for FWD cars where the drive wheels are lifted.
• Short to Medium Distances: Great for moving a car across town or to a nearby state.
• Budget-Conscious Moves: Generally less expensive to rent than an auto transport.
• Compact & Mid-Size Cars: Best for smaller sedans and coupes.

Common Mistakes to Avoid: Many people mistakenly try to tow a rear-wheel drive (RWD) or all-wheel drive (AWD) vehicle with a tow dolly without disconnecting the driveshaft. This can cause severe transmission damage. Always consult your vehicle’s owner’s manual or a mechanic for specific towing instructions for RWD/AWD vehicles.

2. U-Haul Auto Transport Trailer

An auto transport trailer is a full-platform trailer that lifts all four wheels of your towed vehicle off the ground. This provides maximum protection and is suitable for almost any vehicle type.

• Max Towing Capacity: 5,290 lbs (vehicle weight)
• Max Vehicle Width: 79.5" (outside tire to outside tire)
• Max Vehicle Wheelbase: 133"
• Tare Weight (empty): 2,210 lbs

Ideal Use Cases:

• All Vehicle Types: Safely transports FWD, RWD, AWD, and 4×4 vehicles without modification.
• Long-Distance Moves: Ideal for cross-country towing, offering peace of mind that your vehicle is fully off the road.
• Larger Vehicles: Can accommodate larger sedans, small trucks, and SUVs.
• Classic or Valuable Cars: Offers superior protection from road debris and wear on tires/drivetrain.

Expert Insight: Having personally guided countless individuals through their moving journeys, I always recommend the auto transport for anything other than a short FWD car tow. The added safety and protection, especially for long distances or valuable vehicles, are well worth the slightly higher cost.

Key Considerations Before Renting Any U-Haul Trailer

Choosing the right size is only half the battle. Several other critical factors must be considered to ensure a safe and successful towing experience. Overlooking these can lead to serious problems.

1. Your Tow Vehicle: The Foundation of Safe Towing

This is arguably the most crucial factor. Your tow vehicle must be capable of safely handling the weight of the trailer and its maximum load.

• Towing Capacity: Check your vehicle’s owner’s manual for its maximum towing capacity. Never exceed this limit. It’s the single most important number to know.
• Hitch Type: You’ll need a hitch receiver, often Class I, II, III, or IV, and a compatible hitch ball (usually 1-7/8" or 2" for U-Haul trailers). Ensure the hitch ball’s weight rating meets or exceeds your loaded trailer’s gross weight.
• Electrical Connection: U-Haul trailers require a working 4-pin flat electrical connector for tail lights, brake lights, and turn signals. If your vehicle doesn’t have one, U-Haul can often install one.
• Transmission Type: While not a deal-breaker, towing with an automatic transmission often requires using a lower gear (like ‘D’ with overdrive off) to prevent overheating. Manual transmissions handle towing well but require more driver skill.

Pro Tip from Us: Always factor in the trailer’s empty (tare) weight plus the maximum load weight when comparing against your vehicle’s towing capacity. Don’t just consider what you think you’re hauling.

2. What You’re Moving: Details Matter

The items you plan to transport dictate the trailer type and size. Don’t just guess; measure and weigh.

• Volume: Estimate the cubic feet needed for boxes and furniture. For an apartment, a good rule of thumb is 150-200 cubic feet per fully furnished room.
• Weight: Heaviest items should go in the trailer first, positioned over the axle. Know the approximate weight of your major appliances and furniture.
• Dimensions of Largest Items: Measure your longest, widest, and tallest pieces of furniture or equipment. This will confirm if they fit through the trailer door and within its interior.
• Fragility: Enclosed trailers offer better protection for delicate items. If using an open utility trailer, secure fragile items properly and protect them from weather.

3. Distance of Travel: Short Haul vs. Long Haul

The distance you’re traveling can influence your choice and preparation.

• Local Moves: For short distances, you might tolerate a slightly less-than-perfect fit, or opt for multiple trips with a smaller trailer.
• Long-Distance Moves: For cross-country hauls, invest in the right-sized enclosed trailer for protection and efficiency. An auto transport is almost always preferred over a tow dolly for long vehicle moves.

4. Your Budget: Balancing Cost and Value

U-Haul trailer rental costs vary by size, duration, and whether it’s a one-way or in-town rental.

• Rental Fees: Factor in the daily or weekly rental rate.
• Fuel Consumption: Towing significantly impacts fuel economy. Larger trailers and heavier loads mean more trips to the gas station.
• Insurance: U-Haul offers optional coverage plans (Safemove®, Safetow®). Based on my experience, investing in one of these is often a wise decision for peace of mind, especially for valuable cargo or long trips. Your personal auto insurance may not cover rental trailers.

5. Safety First: Loading and Driving

Safety should be your absolute top priority when towing. A properly loaded and driven trailer prevents accidents.

• Weight Distribution: Load about 60% of the weight in the front half of the trailer (closest to the tow vehicle) and 40% in the rear. This creates tongue weight, crucial for stability. Too much weight in the back can cause dangerous swaying.
• Securing the Load: Use moving pads, tie-down straps, and ropes to secure all items inside the trailer, preventing shifting during transit.
• Driving Habits: Drive slower, allow more stopping distance, take wider turns, and be mindful of crosswinds. Check your mirrors frequently.
• Tire Pressure: Always check the tire pressure on both your tow vehicle and the trailer before departure.

Pro Tips for a Smooth U-Haul Trailer Rental Experience

Having successfully navigated countless moves, I’ve gathered some invaluable tips to make your U-Haul experience as smooth as possible. These insights come directly from years of practical application.

1. Reserve Early, Especially for Peak Season: U-Haul trailers are in high demand during weekends, holidays, and summer months. Book your desired trailer size well in advance to avoid disappointment.
2. Inspect Thoroughly Before Leaving: Before you drive away from the U-Haul location, do a complete walk-around. Check the tires, lights, ramp (if applicable), and ensure the hitch is securely connected. Report any damage or issues immediately.
3. Load Correctly – It’s Crucial: As mentioned, proper weight distribution is paramount for safety. Heavy items low and centered, lighter items on top. Secure everything tightly to prevent shifting.
4. Practice Driving with the Trailer: If you’re new to towing, find an empty parking lot and practice turning, backing up, and braking. It feels different, and familiarity builds confidence.
5. Return on Time (or Communicate): U-Haul has strict return policies. Avoid late fees by returning the trailer on schedule. If you anticipate a delay, call the return location immediately.
6. Understand Your Hitch and Ball: Ensure you have the correct size hitch ball (U-Haul typically uses 1-7/8" or 2") and that it’s properly torqued to your hitch. A loose hitch ball is a significant safety risk.

Common Mistakes to Avoid When Renting a U-Haul Trailer

Even with the best intentions, mistakes can happen. Here are some of the most common pitfalls we’ve observed over the years, and how to steer clear of them:

• Underestimating Size and Weight: This is the #1 mistake. People often think they can fit more than they actually can, leading to overloaded trailers or multiple unnecessary trips. Always err on the side of slightly larger rather than too small.
• Incorrect Loading: Improper weight distribution (too much weight in the back) can cause severe trailer sway, making it incredibly dangerous to drive. Load heavy items first, over the axle, and secure everything.
• Not Checking Tow Vehicle Specs: Assuming your SUV or truck "can probably tow it" is a recipe for disaster. Always verify your vehicle’s specific towing capacity and ensure your hitch and wiring are compatible.
• Forgetting About Insurance: Don’t assume your personal auto insurance covers rental trailers. Often, it doesn’t. U-Haul’s optional Safemove® or Safetow® plans offer vital protection against damage and liability.
• Driving Too Fast: Trailers add significant weight and change your vehicle’s dynamics. Driving at highway speeds, especially in windy conditions or on uneven roads, can lead to loss of control. Slow down, especially on turns.
• Ignoring Pre-Trip Checks: Skipping the inspection of tires, lights, and hitch connection can lead to breakdowns or accidents on the road. A few minutes of checks can save hours of trouble.

Frequently Asked Questions About U-Haul Trailer Sizes

Q: Can I rent a U-Haul trailer if I don’t have a hitch?
A: No, you must have a proper hitch receiver and ball installed on your tow vehicle. U-Haul can often install hitches at their corporate locations if you need one.

Q: Do U-Haul trailers have brakes?
A: Most U-Haul trailers do not have independent braking systems. The braking is handled by your tow vehicle. Auto transport trailers do have surge brakes, which engage as your tow vehicle slows down.

Q: What if I need to change my trailer size after booking?
A: It’s best to call U-Haul as soon as possible. While they will try to accommodate changes, availability is not guaranteed, especially during peak seasons.

Q: Can I use a U-Haul trailer for international travel (e.g., Canada or Mexico)?
A: Generally, U-Haul trailers are only permitted for use within the contiguous United States and Canada. Cross-border travel into Mexico is usually prohibited. Always confirm with U-Haul directly.

Q: How do I calculate the tongue weight of my loaded trailer?
A: While U-Haul doesn’t typically provide a specific tool, the general rule of thumb is that the tongue weight (downward force on your hitch) should be 10-15% of the total loaded trailer weight. Proper loading, with heavier items towards the front, helps achieve this.

Conclusion: Your Confident Move Starts Here

Choosing the right U-Haul trailer size is a critical step in any successful hauling or moving project. It’s not just about fitting your items; it’s about safety, efficiency, and peace of mind. By thoroughly understanding the different trailer types, their specific dimensions, and the crucial considerations for towing, you can approach your rental with confidence.

Remember to assess your needs accurately, prioritize your tow vehicle’s capabilities, and always put safety first.
