What size storage unit for a three-bedroom home?
Last updated: November 12, 2026.
A three-bedroom household usually looks at a 10×20 storage unit, and sometimes a 10×30, depending on how much of the house is going in and whether the garage comes too. This page unpacks that rule of thumb, uses Omaha's published average home size carefully, and explains the October 2026 prices we can source — including the 20×20 average we cannot.
The rule of thumb, sized to the house you actually have
The usual industry shorthand:
- A 10×15 (150 square feet) for a small three-bedroom, or a larger one that is only partly stored (some furniture stays, or goes to a new house immediately).
- A 10×20 (200 square feet) for a typical three-bedroom packed densely: appliances, sofa and chairs, dining set, bedroom furniture, and many boxes, with or without a narrow aisle.
- A 10×30 (300 square feet) if the garage, a shed, or bulky outdoor equipment is included, if furniture is oversized, or if you need a walkway you can actually use.
Three bedrooms is a room count, not a volume. A ranch and a two-story house with a basement do not produce the same pile. The basement and the garage are the usual surprises: holiday decorations, tools, and "we'll sort it later" boxes that were invisible in the floor plan. Walk every room, including those, and measure the largest pieces (sofas, mattresses, appliances, a workbench) before you rent. The parent table is the size guide. A one-bedroom is a different conversation: size for a one-bedroom apartment.
Omaha's average home, and what it doesn't tell you
StorageCafe's October 2026 Omaha housing table put the average home at 1,361 square feet, the average apartment at 905, with 204,135 households. We cite 1,361 because it is a published Omaha figure. We do not treat it as the size of a three-bedroom, and we do not convert 1,361 square feet into a storage-unit recommendation. You will not rent 1,361 square feet of storage; you will rent enough floor to stack furniture and boxes, often 200 to 300 square feet if the whole household is going in.
West Omaha and Millard searches often come from house-scale moves. Those pages (West Omaha, Millard) do not have neighborhood 10×20 averages, and we don't invent them. Citywide, a standard 10×20 averaged $128 in both October 2026 surveys; a standard 10×30 averaged $188 to $198. Climate-controlled 10×20 units diverged: $166 on StorageCafe, $247 on UnitSight. Get quotes, and see the 10×20 deep-dive.
We have not found a published Omaha average for a 20×20. If a facility offers one, compare the quote on its own, including door height. Don't ask us to fill in a city average we don't have; we already said this on the cost guide.
Packing a house-scale unit, and the cost of guessing wrong
A 20- or 30-foot-deep unit buries whatever you load first. Leave an aisle, label toward it, and keep an "open first" cluster at the door — tools, a vacuum, a change of clothes, school or work items you may need mid-lease. How to pack and organization tips are worth reading before the truck, not after. Climate control for a whole house of wood furniture through an Omaha summer or winter is a serious monthly premium; see the climate-controlled guide.
Guessing wrong is expensive in both directions. A 10×20 you only half-fill still costs a 10×20 (standard $128 advertised average in October 2026). A 10×15 that's too small can force a second unit, which on 5×10 averages ($59–$68) can exceed the step up to a 10×20. Measure once. For the move around the unit, use the moving checklist.
Vehicles are a separate decision. A three-bedroom move sometimes includes a car, a boat, or an RV that will not live at the new address right away. Those don't belong in the same quote as the 10×20 without a facility rule that allows it, and they don't belong in the same average. Use the car, RV, or boat guides, and don't treat $128 as a vehicle-space price. Drive-up access, on the other hand, is often worth asking for on a house-scale load: appliances and long furniture are easier at a unit door than in a corridor. That feature is independent of climate control, as the climate-controlled vs. drive-up page explains.
If the three-bedroom move is military and you are arriving at Offutt, official Storage In-Transit may already cover household goods for a period. Check that first: military storage near Offutt and Bellevue. A commercial 10×20 is for what the entitlement does not cover, not an automatic first step.
Frequently asked questions
What size storage unit do I need for a three-bedroom house?
The usual rule of thumb is a 10×20 (200 square feet) for a typical three-bedroom household packed densely, or a 10×30 (300 square feet) if the house is large, the garage is coming too, or you want an aisle. A 10×15 can work for a small three-bedroom that is only partly stored. Measure the large pieces. This is a rule of thumb, not a promise, and a three-bedroom in a 1,800-square-foot house is not the same load as a three-bedroom in a 1,200-square-foot one.
Is the Omaha average home a three-bedroom?
We don't have a published "average three-bedroom" size for Omaha. StorageCafe's October 2026 Omaha housing table put the average home at 1,361 square feet. That is an average home, not specifically a three-bedroom, and not a storage-unit size. We cite it as context and we don't treat 1,361 as a 10×20 recommendation. You are storing belongings, stacked, not reproducing the house.
How much does a 10×20 cost in Omaha?
In October 2026 a standard 10×20 averaged $128 a month in both StorageCafe and UnitSight. Climate-controlled 10×20 units averaged $166 (StorageCafe) to $247 (UnitSight) — a wide gap we discuss on the 10×20 guide. A standard 10×30 averaged $188 to $198. Those are advertised averages, not quotes.
What about a 20×20 for a three-bedroom house?
A 20×20 would be 400 square feet, larger than a 10×30. We have not found a published Omaha average for a 20×20, and we will not invent one. If a facility offers that size, compare it as a quote against 10×20 and 10×30 quotes, including door height and month-two rent.
