Introduction
A 10x20 storage unit gives you 200 square feet of floor space, enough to hold the furniture and boxes from a three to four bedroom home, or a smaller home plus a car. It typically costs $195 to $220 a month for a standard unit, or $240 to $340 with climate control added. It sits right between the 10x15, built for a two to three bedroom home, and the 10x30, built for a whole house or multiple vehicles. Below you will find the exact dimensions, what actually fits inside, current pricing, and how it compares to the sizes on either side so you book the right one the first time.
How big is a 10x20 storage unit?
A 10x20 storage unit measures 10 feet wide by 20 feet deep, for 200 square feet of floor space. With a typical 8-foot ceiling, that works out to roughly 1,600 cubic feet of storage volume, and facilities with 9 to 10-foot ceilings offer closer to 1,800 to 2,000 cubic feet.
To put that in perspective, 200 square feet is about the footprint of a two-car garage, or double the floor space of a 10x10 unit. It gives you 50 more square feet than a 10x15 and 100 less than a 10x30, which is the next size up at most facilities.
| Dimension | Measurement |
| Width | 10 feet |
| Depth | 20 feet |
| Floor space | 200 square feet |
| Volume (8-ft ceiling) | ~1,600 cubic feet |
| Volume (9 to 10-ft ceiling) | ~1,800 to 2,000 cubic feet |
| Comparable space | A two-car garage, or double a 10x10 unit |
What fits in a 10x20 storage unit?
A well-packed 10x20 unit holds the entire contents of a three to four bedroom home, with enough room left over for a car or a few oversized items. If you stack carefully and use the full ceiling height, you can typically fit:
-
Furniture from three to four bedrooms: beds, dressers, nightstands, and mirrors
-
A full living room set: a sofa, loveseat, coffee table, bookshelf, and a TV
-
A dining set that seats 4 to 6 people
-
Two major appliances, such as a washer, dryer, or refrigerator
-
50 to 60 medium moving boxes
-
Patio furniture, bikes, and seasonal gear along the walls
-
A car, motorcycle, or small vehicle, if you leave out some of the furniture above
Most people use a 10x20 for one of three reasons: moving a three or four bedroom home, storing a full household alongside a vehicle, or keeping business inventory and equipment that has outgrown a 10x10 or 10x15. If you only need to fit a car or motorcycle without much else, see our Car Storage Size Guide for size-specific options. Our storage unit size guide walks through every size from a 5x5 up to a 10x30 so you can confirm you have the right one.
How much does a 10x20 storage unit cost?
A 10x20 storage unit typically costs $195 to $220 a month for a standard, non-climate-controlled unit, and $240 to $340 a month with climate control added. In expensive metro markets like Los Angeles or New York, the same unit can run well above those figures.
| Unit size | Typical monthly cost | With climate control |
| 10x15 | $150 to $165 | $185 to $260 |
| 10x20 | $195 to $220 | $240 to $340 |
| 10x25 | $225 to $270 | $280 to $400 |
| 10x30 | $260 to $320 | $320 to $470 |
A few things move the price up or down:
-
Climate control. Keeping the unit between about 55 and 80 degrees adds roughly 20% to 40% to the base rent on a unit this size, which is worth it for wood furniture, electronics, and anything sensitive to humidity.
-
Location and season. Rates in large coastal metros run well above these figures, while smaller inland markets run below them. Prices also climb in late spring and summer, the busiest moving months.
-
Access type. A 10x20 is almost always a drive-up unit, since indoor hallways and elevators rarely accommodate a unit this large, and drive-up access makes loading furniture or a vehicle much easier.

10x20 vs. other storage unit sizes
The 10x20 is a popular step-up size for renters who have outgrown a 10x15 but do not need the full 300 square feet of a 10x30. Here is how it compares to the sizes most people cross-shop against it.
| Size | Floor space | Best for | Truck equivalent |
| 10x15 | 150 sq ft | Two to three bedroom home, big furniture and appliances | 15 to 20-foot truck, mostly full |
| 10x20 | 200 sq ft | Three to four bedroom home, or a home plus one vehicle | 20 to 26-foot truck |
| 10x25 | 250 sq ft | Four bedroom home with extra overflow or a vehicle | 26-foot truck, partly full |
| 10x30 | 300 sq ft | Four to five bedroom home, multiple vehicles, or business stock | 26-foot truck, fully loaded |
If your move or inventory does not quite fill a 10x20, a 10x15 unit can save you real money each month. If you are storing a full house plus more than one vehicle, size up to a 10x30 instead.
Is a 10x20 storage unit big enough for a car?
Yes. A 10x20 is the smallest standard size that comfortably fits most sedans and small SUVs with the doors able to open, which makes it the go-to choice for renters combining a vehicle with household storage.
-
Car or small SUV: fits comfortably, usually with enough room along the sides for boxes or smaller furniture.
-
Midsize or full-size truck or SUV: fits, though it leaves little extra space, so a 10x25 or 10x30 is more comfortable.
-
Boat or RV: generally needs an outdoor parking spot or a dedicated vehicle storage lot instead, since length matters more than square footage.
-
Motorcycle or ATV: fits easily, with plenty of room left over for furniture and boxes.
Our Drive-Up vs. Indoor Storage Units guide explains how access type affects both price and how easily you can load a vehicle, and the Car Storage Size Guide breaks down exact dimensions by vehicle type.
Who actually needs a 10x20 storage unit?
A 10x20 fits a specific set of situations better than any other size, which is why it is one of the most requested sizes for larger moves:
-
Families moving a three or four bedroom home between leases or during a renovation.
-
Renters combining household storage with a vehicle, such as a car, motorcycle, or small trailer.
-
Homeowners mid-renovation who need to clear several rooms of furniture at once.
-
Small business owners who need room for inventory, tools, or seasonal stock that has outgrown a smaller unit.
-
Downsizers moving from a house into a smaller home or apartment who are not ready to part with everything at once.
If your situation is smaller, a 10x15 will usually cost you less for the same peace of mind. If you are moving a full house plus more than one vehicle, a 10x25 or 10x30 gives you the room to do it without a second unit.
Tips for packing a 10x20 storage unit efficiently
Getting full value out of 200 square feet comes down to how you load it, not just what you bring.
-
Build a center aisle. A unit this size benefits from a walkway down the middle so you can reach items in the back without unloading everything in front of them.
-
Use the full height. Stack boxes to the ceiling and store furniture like mattresses and tabletops vertically along the walls.
-
Disassemble what you can. Bed frames, tables, and shelving units take up far less room broken down than left whole.
-
Load heavy items first and low. Appliances and boxed items go on the bottom, lighter and more fragile items go on top.
-
Park the vehicle last, if you are storing one. Load furniture and boxes around the edges first, then pull the car or motorcycle in last so it is also the easiest thing to take back out.
-
Protect against moisture. Use pallets or a plastic sheet under anything touching the floor if the unit is not climate controlled.
-
Make an inventory as you load. Our guide on how to create a self storage inventory walks through a simple system, and how to organize a storage unit covers layout tips for units of every size.
