You’re staring at a mountain of cardboard boxes, a sectional that definitely doesn't come apart, and a king-sized mattress that feels more like a lead weight. Panic sets in. Moving is inherently stressful, but the specific dread of standing in your driveway at 8:00 AM wondering what size u haul do i need is a special kind of torture. Get it wrong, and you’re either making three trips across town or paying for a massive 26-foot beast to haul a single studio apartment's worth of IKEA furniture.
Most people guess. They look at a picture of a 10-foot truck and think, "Yeah, that looks big enough." It usually isn't.
The reality of truck rentals is less about the square footage and more about the Tetris-like geometry of your specific life. U-Haul has been the industry standard since 1945, and they’ve refined their fleet into specific tiers, but those "1-2 bedroom" labels they put on the side of the trucks are... let’s call them optimistic. They assume you don't have a hoarding problem or a massive collection of heavy oak furniture. If you’re questioning your choices, you’re already ahead of the curve.
The Smallest Options: When a Van is Actually Enough
If you’re just moving out of a dorm or a small studio, you might be looking at the 8-foot pickup or the cargo van. Honestly, the cargo van is the unsung hero of local moves. It’s way easier to park than a truck, and it handles like a regular SUV. You can fit a queen-sized mattress in there if you’re creative, though it’ll be tight.
For anything larger than a studio, you move into the actual box trucks. The 10-foot U-Haul truck is the smallest of the "real" trucks. It’s perfect for a studio or a very lean one-bedroom apartment. But here is the catch: it doesn't have a ramp.

If you have a heavy dresser or a washing machine, you and a friend are going to be dead-lifting that weight three feet off the ground. It’s a literal back-breaker. I’ve seen people regret the 10-footer solely because of the ramp situation. If you have anything heavy, skip the 10 and go straight to the 15-foot model.
The Mid-Range Sweet Spot: 15 to 20 Feet
The 15-foot truck is the most popular size for a reason. It’s the smallest one that includes a pull-out loading ramp. U-Haul markets this for a "1-2 bedroom home or apartment." This is usually accurate for a one-bedroom, but if you have a two-bedroom place with a kitchen table, a couch, and two full bedroom sets, you are going to be packing that thing to the ceiling.
Then there’s the 17-footer. It’s a bit of an odd duck. It’s slightly longer, giving you that extra breathing room for a large sectional or a bike collection.
When you hit the 20-foot U-Haul, you’re entering the "growing family" territory. This is designed for two-to-three-bedroom homes. It has a larger cab, often with a middle seat, so three people can actually ride in the truck. This is a big deal if you’re doing a long-distance move and don't want to drive two separate cars. The 20-footer is also significantly wider and taller. You can stand up straight inside without hitting your head, which makes the actual labor of moving significantly less claustrophobic.

Going Big: The 26-Foot Monster
The 26-foot truck is the largest DIY rental U-Haul offers. It is a massive vehicle. If you aren't used to driving something that big, the first five minutes behind the wheel will be terrifying. You have to account for "tail swing"—when you turn right, the back left of the truck swings out wide.
But if you have a 3-4 bedroom house, this is your only real choice. It can hold upwards of 500 medium boxes. According to moving experts at sites like Move.org, the 26-foot truck is the only one that truly accommodates a large family home in a single trip. It’s also the most likely to have a "Mom’s Attic," that little compartment that hangs over the cab of the truck. It’s the perfect spot for fragile items or electronics that you don't want getting crushed by a stray wardrobe.
Why "What Size U-Haul Do I Need" Is Often the Wrong Question
The question shouldn't just be about the size of the truck, but the volume of your stuff.
We tend to underestimate how much space "small" things take up. A stack of 20 boxes takes up way more room than a sofa. Professionals often use a cubic foot calculation. For instance, a 15-foot truck has about 764 cubic feet of space. A standard queen bed set is about 65 cubic feet. A sofa is 50. Do the math, and it adds up fast.
- The "One Size Up" Rule: Almost every professional mover will tell you to rent one size larger than you think you need. Why? Because a half-empty 20-foot truck is a minor annoyance, but a 15-foot truck that’s full while you still have a dining room table sitting on the sidewalk is a disaster.
- Weight Limits: It’s not just about space; it’s about GVWR (Gross Vehicle Weight Rating). If you are moving a library’s worth of books or a garage full of power tools, you might hit the weight limit of a smaller truck before you fill the space.
- Fuel Costs: The bigger the truck, the worse the gas mileage. The 26-footer gets about 7-10 miles per gallon. If you’re moving across the country, that fuel bill might actually rival the rental cost.
Real World Examples: Which One Are You?
Let’s look at a few scenarios that play out every weekend across the country.
The College Grad: Moving from a dorm to a first apartment. You’ve got a desk, a bed, and a few dozen boxes. You don't need a truck. Get the Cargo Van. It’s cheaper on gas and fits into standard parking spots.

The Urban Couple: Moving from a 1-bedroom apartment in the city to a suburban 2-bedroom. You have a couch, a bed, a table, and maybe a guest bed. You think you need the 10-foot truck, but you actually need the 15-foot truck. You’ll want that ramp, trust me. Your knees will thank you.
The Full House: A 3-bedroom suburban home with a garage and a shed. Don't even look at the 20-footer. You need the 26-foot truck. People always forget the stuff in the garage—the lawnmower, the bikes, the plastic bins of holiday decorations. That stuff takes up an incredible amount of volume.
Managing the Logistics of a Large Rental
Once you decide on the size, the logistics change. Driving a 26-foot truck requires checking clearances for every gas station and fast-food drive-thru (don't even try the drive-thru). You also need to think about the "low clearance" signs on old bridges. Google Maps has a bad habit of sending trucks under bridges that are only 10 feet tall. A 26-foot U-Haul is about 12 feet high. You do the math.
Also, consider the "towing" factor. If you need to move your car as well, U-Haul offers tow dollies and auto transports. Attaching an auto transport to a 20-foot or 26-foot truck makes you a "road train." It’s manageable, but it adds another 15-20 feet to your total length.
How to Pack to Save Space (And Sanity)
If you end up with a truck that’s a little too small, how you pack becomes everything. Start with the heaviest items at the front (near the cab). This keeps the center of gravity stable. Stand mattresses up against the walls. Use "fillers" like pillows and bags of clothes to plug the gaps between furniture. This stops things from shifting and breaking during the drive.
Secure everything with tie-down straps. U-Haul trucks have rails along the inside for this exact reason. If you leave gaps, the first time you hit the brakes, your grandmother's china is going to become a projectile.
Actionable Steps for a Successful Move
- Inventory your "Big Five": List your bed, couch, dining table, fridge (if moving appliances), and any large desks. These dictate the minimum truck size regardless of how many boxes you have.
- Measure the largest item: If you have an oversized sectional or a massive armoire, measure its longest dimension. Ensure it can actually fit through the door of a 10-foot or 15-foot truck, which have narrower openings than the larger models.
- Check the ramp status: If you are moving alone or with just one other person, prioritize a truck with a ramp (15' and up). It turns a four-hour loading process into a two-hour one.
- Reserve early: In the moving world, June and July are peak season. If you wait until the week of your move to decide what size you need, you might be stuck with whatever is left on the lot—which is usually the 26-footer that costs double the fuel.
- Be honest about your "stuff": We all think we have less than we do. If you’re torn between two sizes, go up. The peace of mind is worth the extra $20-$40 in rental fees.
Choosing the right size is the difference between a long day and a nightmare. Most people find that the 15-foot truck is the safest bet for the average apartment dweller, while the 26-foot truck is non-negotiable for anyone with a yard and a mortgage. Take a walk through your house right now with a critical eye. If you see more than one room of furniture, stop looking at the vans. You need a real truck.
Check your local U-Haul inventory at least two weeks before your move date. Get the insurance—it’s cheap and covers the overhead damage that your regular car insurance definitely won't. Load the heavy stuff first, drive slower than you think you need to, and remember to swing wide on those right turns.
