A 20x30 storage unit is 600 square feet — 20 feet wide by 30 feet deep. That's about the size of a three-car garage, and twice the floor of a 10x30, the biggest size most self-storage facilities carry. Cubic feet depends on the ceiling: 4,800 with an 8-foot ceiling, or 9,600 cubic feet with the 16-foot ceilings at Elite.

Most self-storage sites don't build 20x30s, so this size usually shows up at facilities designed for vehicles and larger loads. Here's what the space actually gives you.

How many square feet is a 20x30?

600 square feet: 20 times 30. For a sense of scale, that's three 10x20 units, or a small one-bedroom apartment.

How many cubic feet is a 20x30 storage unit?

Ceiling height	Cubic feet
8 feet	4,800 cubic feet
10 feet	6,000 cubic feet
12 feet	7,200 cubic feet
16 feet (Elite)	9,600 cubic feet

The ceiling matters more than people expect. A 16-foot ceiling doubles what an 8-foot one holds on the same floor, which is the difference between storing a house and storing a house plus everything in its garage.

What fits in a 20x30 storage unit?

• Two cars side by side, plus gear — both cars fit across the 20-foot width with room to open doors, and you still have 10 to 15 feet of depth behind them for tools, tires, and shelving.
• A camper or travel trailer — up to roughly 26 to 27 feet overall, hitch included, as long as it clears the door. A 12-foot door handles most travel trailers and many Class C motorhomes; taller rigs need one of the 14-foot doors.
• A boat on its trailer — most boats up to about 20 to 22 feet, since the trailer tongue and motor add several feet to the overall length. See boat storage in Bakersfield.
• A whole house, with room to walk — even a five-bedroom home, with aisles left in so you can reach things. See what size unit a 5-bedroom house needs.
• A house plus a vehicle — the move-and-renovate combination that usually means renting two standard units.
• Small-business stock — pallets, shelving, or pallet racking, with a drive-up door you can back a truck to.

What a 20x30 at Elite comes with

At Elite, the 20x30 is our smallest unit, and it's built the same as our largest:

• Fully enclosed and drive-up — four walls, a roof, and a roll-up door you pull straight up to.
• 16-foot ceilings — room to stack high or install shelving and racking (floor- or wall-mounted racking needs owner approval first).
• Concrete floors and concrete drive aisles.
• 120-volt outlets and lighting inside the unit.
• Insulated — R30 ceiling and R19 walls. That cuts the Bakersfield heat a lot, but it isn't climate control.
• A separate 3 x 7 man door, so you don't have to raise the big door to grab something.
• A gated, fenced site with 34 cameras recording and your own four-digit gate code.

How a 20x30 compares to other sizes

Unit size	Square feet	Roughly holds
10x30	300 sq ft	A four- to five-bedroom home, or a car plus boxes
20x20	400 sq ft	Two cars side by side, or a large house
20x30	600 sq ft	Two cars plus gear, a camper or boat, or a whole house with aisles
20x40	800 sq ft	Two cars plus a boat, or an RV in the mid-30-foot range
20x50	1,000 sq ft	A large RV, or several vehicles

When you need more than a 20x30

If you're storing a motorhome or fifth wheel over about 27 feet, or more than two vehicles, size up. Elite's units run from 600 to 2,220 square feet, all 20 feet wide, and can take RVs up to 45 feet in the longer units. See how big a 20x40 is or large storage units in Bakersfield.

Frequently asked questions about 20x30 storage units

How big is a 20x30 storage unit?

20 feet wide by 30 feet deep, or 600 square feet. With Elite's 16-foot ceilings, that's 9,600 cubic feet.

How many cars fit in a 20x30?

Two, side by side, with space behind them for gear. Three standard cars won't fit comfortably, because the 30-foot depth isn't enough to park two in a row.

Can an RV fit in a 20x30 storage unit?

A smaller one can. Travel trailers and Class B or C motorhomes up to roughly 26 to 27 feet overall fit, provided they clear the door height. Measure the full length including the hitch, and the height including the A/C unit on the roof.

Is a 20x30 the same as a three-car garage?

It's in the same range. Three-car garages usually run 600 to 900 square feet; a 20x30 is the compact end of that.

Is a 20x30 storage unit climate controlled?

At Elite, no. The units are insulated (R30 ceiling, R19 walls), which keeps them much cooler than an uninsulated metal unit in a Bakersfield summer, but there's no heating or cooling system.

Can I work in a 20x30 unit?

Minor work inside the unit is allowed at Elite, but no work on vehicles of any kind, no fluids, and no retail sales to the public.
