A 20x20 storage unit is 400 square feet — 20 feet wide by 20 feet deep. With an 8-foot ceiling that's 3,200 cubic feet. It's roughly the size of a standard two-car garage, and it's the first size on the chart that's wide enough to park two cars side by side.

20x20 units are less common than the 10-foot-wide sizes most facilities build, so it's worth knowing exactly what you get before you go looking for one.

How many square feet is a 20x20?

400 square feet: 20 times 20. That's double a 10x20 and a third more than a 10x30. It's a common two-car garage size too, though many newer garages run a bit larger, around 22x22 or 24x24.

How many cubic feet is a 20x20 storage unit?

Ceiling height	Cubic feet
8 feet	3,200 cubic feet
10 feet	4,000 cubic feet
12 feet	4,800 cubic feet
16 feet (Elite's ceiling height)	6,400 cubic feet

Can two cars fit in a 20x20 storage unit?

Usually, yes. Two average cars side by side take up about 13 to 15 feet of width with mirrors, which leaves a few feet to open doors. Most sedans and SUVs are 15 to 17 feet long, so they fit the 20-foot depth with room at the front or back.

Three things can stop it:

• The door. A single 10-foot door means you'll be angling the second car in around the first. Ask for the door width before you sign.
• Long trucks. A full-size crew-cab pickup can run 19 to 20 feet or more. In a 20-foot-deep unit you may not be able to close the door.
• Wanting anything else in there. Two cars fill a 20x20. If you also want tools, a workbench, or boxes, you need more depth.

For single-vehicle sizing, see what size storage unit you need for a car.

What else fits in a 20x20?

• A five-bedroom house or more — a large home's furniture, appliances, and boxes, with a walking aisle left in. See what size unit a 5-bedroom house needs.
• One car plus a household — the car on one side, the furniture and boxes on the other.
• A workshop or hobby space — where the facility allows it, a 20x20 is big enough for a bench and real working room.
• Business inventory — roughly 16 to 20 pallets on the floor, more with racking.

How a 20x20 compares to other sizes

Unit size	Square feet	Roughly holds
10x20	200 sq ft	A three- to four-bedroom home, or one car
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, or a small camper or boat
20x40	800 sq ft	Two cars plus a boat, or an RV in the mid-30-foot range

Same width, more depth: where Elite fits

Elite doesn't rent 20x20s. Every one of our units is the same 20 feet wide as a 20x20, but they start at 30 feet deep and run much longer — from about 600 to 2,220 square feet, enclosed and drive-up, with 16-foot ceilings and 12- to 14-foot roll-up doors. Two cars fit side by side in every unit, with the extra depth left over for tools, boxes, a boat, or simply room to walk around.

If you're looking at a 20x20 because you want to store two vehicles and still be able to use them, a 20x30 is the size that stops it from feeling packed.

Frequently asked questions about 20x20 storage units

How big is a 20x20 storage unit?

20 feet wide by 20 feet deep, or 400 square feet. With an 8-foot ceiling that's 3,200 cubic feet, about the size of a two-car garage.

Is a 20x20 the same as a two-car garage?

Close. 20x20 is the small end of two-car garage sizes. Many garages are 22x22 or 24x24, which gives you more room to open doors.

How many square feet is 20 by 20?

400 square feet.

Can a truck fit in a 20x20 storage unit?

Most mid-size pickups, yes. A full-size crew-cab with a long bed can be 20 feet or longer, which won't fit with the door closed. Measure bumper to bumper before you rent.

Is a 20x20 bigger than a 10x30?

Yes, by 100 square feet. A 20x20 is 400 square feet; a 10x30 is 300.

Does Elite rent 20x20 units?

No. Our units are all 20 feet wide and start at 30 feet deep (about 600 square feet). Contact us if you'd like to know which unit fits what you're storing.
