Most full 4-bedroom houses need a 20x25 or 20x26 storage unit, a lightly furnished or partially emptied 4-bedroom can fit in a 10x25 or 14x20, and a full 4-bedroom with garage and basement gear usually needs the 20x26. At AA Personal Storage in Parowan, Utah, a 10x25 rents for $125 a month, a 14x20 for $145, a 15x20 for $155, a 20x25 for $200 (waiting list), and a 20x26 for $210 (as listed in November 2026).
Picking the right storage unit size for a 4 bedroom house is mostly about how much stuff you own, not the bedroom count alone. This guide covers a size chart, a room-by-room checklist, door and ceiling sizes at our Parowan facility, and a packing plan. Compare every size we rent in our full storage unit size guide.
For most families emptying a full 4-bedroom house, a 20x25 or 20x26 is the right size. Our Rent page describes those units as fitting "the contents of a four-bedroom house with some major appliances" and holding "the contents of about a 40 ft. moving van." A remodel or lightly furnished home can work in a 10x25 or 14x20. Rates below are from our Rent page on November 5, 2026.
| Your 4-bedroom | Suggested size | Floor space | Monthly rate at AAPS |
|---|---|---|---|
| Light / remodel: clearing furniture only, few appliances, under about 60 boxes | 10x25 | 250 sq ft | $125 |
| Partial empty: three to four bedroom sets, sofa, dining set, washer and dryer | 14x20 | 280 sq ft | $145 |
| Average full house leaning compact: four bedrooms, living room, kitchen, some garage gear | 15x20 | 300 sq ft | $155 |
| Average full 4-bedroom house with appliances | 20x25 or 20x26 | 500 or 520 sq ft | $200 waitlist / $210 |
| Full house with garage, basement, bulky furniture, or a piano | 20x26 | 520 sq ft | $210 |
These are estimates, and box counts are general rules of thumb. AA Personal Storage does not offer a 10x20; our ladder jumps from 10x15 to 10x25, then to 14x20 and larger.
Sometimes, but only if you are not storing the whole house. Our Rent page says the 10x25 fits "the contents of a multi-bedroom house, including several oversized items like a couch, a refrigerator, a washer/dryer and a dining room set." That works for a light 4-bedroom or a remodel; a full house with garage and basement gear usually outgrows 250 square feet.
A 10x25 fits when you are clearing furniture during a remodel, kids' rooms use twin beds, you leave appliances behind, and you pack tightly with mattresses on end. It has a 9-foot ceiling and a door 8 feet wide by 7 feet 10 inches tall, and it showed "Only 1 left!" in early November 2026. See what fits in a 10x25 storage unit or what fits in a 10x15 storage unit.
Step up to a 14x20 ($145 a month) or 15x20 ($155 a month) when a 10x25 feels tight but you do not yet need a 20x26. These sizes fit a 4-bedroom that is mostly furniture and appliances without a packed basement.
| Feature | 10x25 | 14x20 | 15x20 |
|---|---|---|---|
| Floor space | 250 sq ft | 280 sq ft | 300 sq ft |
| Ceiling height | 9 ft | 10 or 11.5 ft | 10 ft |
| Door width | 8 ft | 7 ft 11 in | 11.5 ft |
| Door height | 7 ft 10 in | 8 ft | 8 ft |
| Monthly rate (Nov 2026) | $125 | $145 | $155 |
These units are wider than a 10x25, so you can stack furniture in two rows. Our Rent page says they fit "the contents of a multi-bedroom house, including several oversized items like a couch, a refrigerator, a washer/dryer and a dining room set." The 15x20 has the widest enclosed door we offer at 11.5 feet; the 14x20 offers an 11.5-foot ceiling option for taller stacks.
Because the rent page sizes those units for a four-bedroom house. Word for word: "It fits the contents of a four-bedroom house with some major appliances. Will hold the contents of about a 40 ft. moving van."
The 20x26 is 520 square feet with a 12-foot ceiling and a door 9 feet 11 inches wide by 8 feet tall, at $210 a month. The 20x25 is 500 square feet with the same door width at $200 a month; it was on a waiting list on November 5, 2026, while the 20x26 showed "Only 1 left!" Plan on this size for four bedroom sets, a sectional, dining set, appliances, and garage or basement overflow, or roughly 100 or more boxes (a general estimate). If your inventory looks closer to a 3-bedroom, see our storage unit size for a 3-bedroom guide first.
Count big items first; furniture fills a unit faster than boxes. Here is a typical 4-bedroom checklist.
Near the top of each range with appliances plus garage and basement gear, plan on a 20x26. Skip the basement and leave appliances behind, and a 14x20 or 15x20 may be enough.
All units are drive-up and ground level with roll-up doors, and asphalt runs up to every unit so you can back a truck to the door. None of these enclosed units have inside lighting, so plan daylight moves or bring a battery lantern.
| Unit | Door (width x height) | Ceiling | Rate |
|---|---|---|---|
| 10x15 (9 ft) | 8.7 ft x 8 ft | 9 ft | $75 |
| 10x15 (10 ft) | 7 ft 10 in x 8 ft | 10 ft | $75 |
| 10x25 | 8 ft x 7 ft 10 in | 9 ft | $125 |
| 14x20 | 7 ft 11 in x 8 ft | 10 or 11.5 ft | $145 |
| 15x20 | 11.5 ft x 8 ft | 10 ft | $155 |
| 20x25 | 9 ft 11 in x 8 ft | 9 ft | $200 waitlist |
| 20x26 | 9 ft 11 in x 8 ft | 12 ft | $210 |
Measure your largest piece before you choose. Anything under 7 feet 10 inches tall fits every door on this list.
Load the heaviest, least-needed items at the back and keep a walkway. A good plan for a 15x20 or 20x26:
Use same-size boxes, keep heavy boxes under 50 pounds, and put pallets or plastic sheeting under items on the concrete floor. Prop refrigerator and washer doors slightly open. More tips: how to pack your storage unit for easy use.
