10x20 storage unit
Researched and written by Ashley Davis · Reviewed by Emily Johnson · Last reviewed August 2026
A ten by twenty unit is 200 square feet, the footprint of a standard single garage, and with an eight-foot ceiling it holds roughly 1,600 cubic feet. That takes a three or four bedroom house: several mattress sets, a full living room, a dining set, major appliances, garden equipment and well over a hundred boxes. It is also the smallest unit most people can comfortably store a car in, where the facility permits vehicles at all.
What fits in a 10x20 storage unit?
Three or four bedrooms, which in practice is a whole family house minus the garage. Three or four mattress sets, a sectional or two sofas, a dining table with six chairs, several dressers and wardrobes, a refrigerator, a washer and dryer, bicycles, garden tools, and a hundred to a hundred and fifty boxes. A house with a workshop or a large garage usually needs a ten by thirty instead.
How big is a 10x20 in feet and square feet?
Ten feet wide by twenty feet deep, which is 200 square feet, and an eight-foot ceiling gives roughly 1,600 cubic feet. That is the same footprint as a standard single garage, which is the most useful mental picture: if the contents would fit in a garage with the door closed, they fit here.
Can you store a car in a 10x20?
Physically yes for most saloons and small trucks, contractually only sometimes. Facilities that allow vehicles usually require proof of registration and current insurance in the renter's name and a vehicle in running condition, and many bar vehicles from interior units entirely for fire reasons. Ask before you book rather than on the day, because a refused vehicle on move-in day has nowhere to go.
Is an aisle worth the space in a 10x20?
In a unit this deep, yes. Twenty feet of depth means the back wall is unreachable without unloading the front, so a two-foot centre aisle costs roughly a fifth of the floor and buys access to everything. Load one side with what you will never touch and the other with what you might, and label every box on the side that faces the aisle rather than on the top.
