What Size U-Haul Do You Need? A Room-by-Room Guide

Published: July 16, 2026

Figuring out what size U-Haul you need comes down to one number: total cargo volume in cubic feet. A studio or one-bedroom home fits a 10' or 15' truck, a two-to-three-bedroom home needs a 20', and a four-bedroom-plus house calls for the 26'. Room count is a shortcut, not the real answer — a densely furnished one-bedroom can out-volume a sparse two-bedroom. Undersize the truck and you pay for a second trip, extra mileage, and a lost half-day. This room-by-room guide gives you a repeatable method to size it right the first time.

U-Haul Truck Sizes at a Glance (10' to 26')

U-Haul rents four main box trucks — 10', 15', 20', and 26' — plus a cargo van and pickup for small loads. Each jump adds roughly 250 to 660 cubic feet of usable space. The table below is your working u-haul size chart, built from the interior u-haul cargo dimensions and volumes U-Haul publishes.

Truck	Cargo Volume	Interior L × W × H	Best For
Cargo van	~245 cu ft	9'6" × 5'7" × 4'7"	A dorm room, a few boxes
10' truck	~402 cu ft	9'11" × 6'4" × 6'2"	Studio, 1 bedroom
15' truck	~764 cu ft	15' × 7'8" × 7'2"	Small 2 bedroom
20' truck	~1,016 cu ft	19'6" × 7'8" × 7'2"	2–3 bedrooms
26' truck	~1,682 cu ft	26'5" × 8' × 8'3"	4+ bedrooms

These figures reflect U-Haul truck capacity as listed on the company's rental pages. Note the 15' and 20' share the same width and height — the 20' simply adds four and a half feet of floor length. That extra length is what separates a cramped move from a comfortable one.

Q: How much can a 26-foot U-Haul hold?
A: The 26' truck offers roughly 1,682 cubic feet of cargo space — enough for a fully furnished four-bedroom home per U-Haul's published u-haul truck sizes.

Why Guessing Wrong Costs You Money and a Second Trip

Undersizing is the single most expensive sizing mistake. When the truck fills before the house empties, you either leave belongings behind or drive back — burning fuel, mileage charges, and hours you did not budget. On a long-distance move, a second trip is often impossible.

Oversizing wastes money too, but less dramatically. A too-big truck costs more per day and per mile, and loosely packed furniture shifts and gets damaged in transit. The goal is the smallest truck that fits your load with a modest buffer.

Pro Tip: Before you book, do a fast walkthrough and photograph every room. A 20-minute inventory beats an on-the-day guess and gives any mover a precise basis for a quote.

Q: What happens if my U-Haul is too small?
A: You either abandon items or make a second trip, adding mileage fees and hours — the exact cost this guide helps you avoid by sizing to cubic feet.

Studio and One-Bedroom: What Fits in a 10' or 15'

A studio or lightly furnished one-bedroom fits the 10' truck; add a home office, a full bedroom set, or a sofa sectional and you want the 15'. The debate here is really 10 foot vs 15 foot u-haul, and the deciding factor is bulky furniture, not box count.

The 10-foot truck swallows a queen mattress, a small dresser, a loveseat, and a stack of boxes with room to spare — but no more. The 15-foot truck adds enough length for a king bed, a full-size sofa, a dining set, and appliances if you own them.

Q: Is a 15-foot U-Haul big enough for a 1-bedroom?
A: Yes. A 15' U-Haul (~764 cu ft) comfortably holds a standard one-bedroom, including a king bed, sofa, and 15–20 boxes, with buffer space left over.

Both trucks include a low, wide loading ramp and "Mom's Attic" — the storage nook above the cab that's perfect for lamps, mirrors, and fragile flat items.

Two to Three Bedrooms: Sizing the 20' Truck

The 20' truck is the right call for most two-to-three-bedroom homes. When people ask what size truck for 2 bedroom apartment moves, the honest answer is: the 15' works only for a small, sparsely furnished unit — the 20' is the safe default.

Here's a real-world example. A typical two-bedroom apartment — two beds, a sofa, a dining table, a dresser, a bookshelf, appliances, and 30-plus boxes — runs close to 900 cubic feet loaded. That squeezes into a 15' truck only if you play Tetris and skip the buffer. Load the same apartment into a 20' truck and it fits with a comfortable margin for awkward items and shifting.

The difference between the two shows up on moving day. In the 15', furniture is stacked to the ceiling with no give; in the 20', the load is stable and quick to secure with the tie-down rails.

Four Bedrooms and Up: When You Need the 26'

A four-bedroom house needs the 26' truck — full stop. At roughly 1,682 cubic feet, it holds the contents of a large home in one load, sparing you the second trip that a 20' would force.

The 26' also has the tallest interior at over eight feet, which matters for standing bookcases, wardrobes, and tall appliances. Its longer ramp makes loading heavy pieces less punishing on your back and your movers.

Pro Tip: For a home this size, load in three passes — heaviest and largest items against the cab first, mid-weight furniture next, then boxes and soft goods filling the gaps. This keeps the load balanced and the truck legal to drive.

If you're moving cross-country, review how to pack a truck for a long-distance move before you start — weight distribution matters more the farther you drive.

The Room-by-Room Volume Method

This is the method that beats every generic label. Instead of trusting a "fits a 2-bedroom" tag, add up the cubic feet of your actual belongings, then match the total to a truck. It's the core of any reliable moving truck size guide.

Movers commonly estimate furniture volume like this:

Item	Approx. Volume
Queen mattress + box spring	~65 cu ft
Three-seat sofa	~50 cu ft
Refrigerator	~45 cu ft
Dresser or armoire	~30 cu ft
Dining table	~30 cu ft
Bookshelf	~20 cu ft
Standard medium box	~3–4 cu ft

Walk each room, list the big pieces, and count your boxes. Add the totals, then add 15% for buffer. Match the final number to the size chart above: under 400 cu ft picks the 10', under 764 the 15', under 1,016 the 20', and beyond that the 26'.

Pro Tip: Count boxes in packing units, not guesses. Fifty medium boxes is roughly 175–200 cubic feet on its own — enough to bump you up a truck size before a single piece of furniture is loaded.

Special Items That Change the Math (Pianos, Appliances, Gym Gear)

Certain items break the room-by-room rules. An upright piano, a full weight rack, a treadmill, or a chest freezer each eats disproportionate space and demands careful placement — usually against the cab wall, loaded first.

Appliances and oversized furniture also need prep. Refrigerators must be defrosted and secured; pianos need specialized moving equipment and, sometimes, hoisting. GoBorn's specialty crews handle piano moving, safes, and white-glove pieces that a standard rental setup isn't built for.

Before any of it goes up the ramp, spend time preparing your furniture before loading — disassembled bed frames and wrapped surfaces both save space and prevent damage.

If you own two or more of these heavy specialty items, size up a level. The math for a two-bedroom with a piano and a home gym looks more like a three-bedroom.

When to Size Up vs. Make Two Trips

When your estimate lands within about 10% of a truck's ceiling, size up. The extra day rate on the next truck almost always costs less than a return trip's fuel, mileage, and lost time — and it protects your furniture from over-packing.

Make two trips only when the move is short and local, the overflow is small, and a larger truck genuinely isn't available. For any long-distance or one-way move, a second trip is off the table, so build in the buffer from the start.

The practical rule from movers: leave roughly 10–15% of the box empty when you think you're done. That margin absorbs the closet you forgot, the garage you underestimated, and the natural shifting of a loaded truck. Driving a fully packed rental also demands care — review the Federal Motor Carrier Safety Administration's guidance on operating larger vehicles before you hit the highway. With more than 8% of Americans relocating in a typical year per the U.S. Census Bureau, sizing your truck right is one of the most repeatable ways to keep a move on budget.

Frequently Asked Questions

What size U-Haul do I need for a 2-bedroom apartment?

Most two-bedroom apartments need a 20' U-Haul, which offers about 1,016 cubic feet. A 15' truck (~764 cu ft) works only for a small, sparsely furnished two-bedroom with minimal appliances. The deciding factor is bulky furniture and box count, not room number alone — a two-bedroom with a piano or home gym pushes you toward the 20' or even the 26'. Use the room-by-room volume method: add the cubic feet of your beds, sofa, tables, dressers, and boxes, then add a 15% buffer. If the total tops 760 cubic feet, book the 20' rather than gambling on a 15' and risking a second trip.

Is a 15-foot U-Haul big enough for a 1-bedroom?

Yes. A 15-foot U-Haul provides roughly 764 cubic feet — comfortably enough for a standard one-bedroom home, including a king bed, a full-size sofa, a dresser, a dining set, and 15 to 20 boxes, with buffer space to spare. If your one-bedroom is lightly furnished, you can often drop to the 10' truck (~402 cu ft) and save on the rental. Choose the 15' when you own larger appliances, a sectional sofa, or a home office setup. The 15' also includes Mom's Attic above the cab, which adds handy space for lamps, mirrors, and fragile flat items.

How many rooms fit in a 26-foot U-Haul?

A 26-foot U-Haul holds a fully furnished four-bedroom home — generally four to five rooms plus a living room, dining room, kitchen, and garage overflow. With about 1,682 cubic feet of cargo volume and an interior over eight feet tall, it's U-Haul's largest box truck and the only rental sized for large houses in a single load. Two- and three-bedroom homes fit the 20', so reserve the 26' for genuinely large moves or homes with heavy specialty items like pianos, safes, or gym equipment. Loading in three weight-balanced passes keeps a truck this size stable and safe to drive.

What happens if my U-Haul is too small?

If your truck is too small, you face two bad options: leave belongings behind or make a second trip. A second trip adds fuel, extra mileage charges, and several lost hours — and on a one-way or long-distance move, it's usually impossible, meaning items get abandoned or shipped separately at added cost. Overloading a too-small truck also forces ceiling-high stacking, which shifts in transit and damages furniture. The fix is prevention: estimate your total cubic feet with a room-by-room inventory, add a 15% buffer, and size up when your total lands within 10% of a truck's ceiling.

How do I estimate the truck size I need?

Use the room-by-room volume method. Walk each room and list the large furniture, using standard estimates — about 65 cubic feet for a queen mattress set, 50 for a sofa, 45 for a refrigerator, and 3 to 4 per box. Add up every piece and every box, then add 15% for buffer and shifting. Match the total to U-Haul's capacities: under 400 cubic feet fits the 10', under 764 the 15', under 1,016 the 20', and beyond that the 26'.
