Most 3-bedroom houses need a 10x25 storage unit, a lightly furnished 3-bedroom can fit in a 10x15, and a full 3-bedroom house with a garage, appliances, and yard gear usually needs a 14x20 or 15x20. At AA Personal Storage in Parowan, Utah, a 10x15 rents for $75 a month, a 10x25 for $125, a 14x20 for $145, and a 15x20 for $155 (as listed in November 2026).
Picking the right storage unit size for a 3 bedroom house is mostly about how much stuff you own, not the bedroom count. This guide gives you a quick size chart, a room-by-room checklist, the real door and ceiling sizes at our Parowan facility, and a packing plan that keeps a big unit usable. If you want to compare every size we rent first, start with our full storage unit size guide.
For most families, a 10x25 is the right storage unit size for a 3-bedroom house. It has 250 square feet of floor space and a 9-foot ceiling, which covers three bedroom sets, a living room, a dining set, major appliances, and a good stack of boxes.
Use this chart as a starting point. Rates are from our Rent page on November 1, 2026.
| Your 3-bedroom | Suggested size | Floor space | Monthly rate at AAPS |
|---|---|---|---|
| Light: kids' rooms with twin beds, no appliances, few boxes | 10x15 | 150 sq ft | $75 |
| Average house: three bedroom sets, sofa, dining set, washer and dryer, 50 to 75 boxes | 10x25 | 250 sq ft | $125 |
| Full house: everything above plus a fridge, sectional, garage and yard items | 14x20 | 280 sq ft | $145 |
| Full house with bulky pieces: piano, large sectional, workshop tools | 15x20 | 300 sq ft | $155 |
| 3-bedroom plus a basement, big garage, or lots of extras | 20x26 | 520 sq ft | $210 |
These are estimates. A king bed and a twin bed take very different amounts of room, and so do a loveseat and a sectional. Box counts are general rules of thumb, not measured figures.
Only if it is lightly furnished. Our Rent page describes the 10x15 as fitting "the contents of three full bedrooms and larger items such as a piano, couches, tables, or large-screen TVs," but that means bedroom furniture, not a whole house with a kitchen, garage, and appliances.
A 10x15 is a good fit for a 3-bedroom when:
We have two 10x15 versions in Parowan, both $75 a month: one with a 9-foot ceiling and a door 8.7 feet wide and 8 feet tall, and one with a 10-foot ceiling and a door 7 feet 10 inches wide and 8 feet tall. See what fits in a 10x15 storage unit for a detailed packing list.
A 10x25 gives you 250 square feet, two-thirds more floor space than a 10x15, for $50 more a month. Our Rent page says it 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."
The long, narrow shape works well for a whole house. You can line the back with appliances and mattresses, run furniture down both sides, and keep a walkway down the middle to reach boxes later. The door at AA Personal Storage is 8 feet wide and 7 feet 10 inches tall, so a queen mattress, a fridge, or a sofa on end goes straight in.
The 10x25 is popular, and it showed "Only 1 left!" on our Rent page in late October 2026, so check availability before moving day. For a full packing plan, read what fits in a 10x25 storage unit.
Step up to a 14x20 ($145 a month) or 15x20 ($155 a month) when your 3-bedroom comes with a full garage, a big sectional, a piano, or more than about 75 boxes. These units are wider, so you can stack furniture in two rows instead of one long line.
| 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 |
The 15x20 has the widest door we offer on an enclosed unit at 11.5 feet, which makes it the easiest to load with a sectional, a dining table, or a large gun safe on a dolly. The 14x20 comes in a version with an 11.5-foot ceiling, which helps if you stack boxes high.
For a 3-bedroom with a basement or a packed garage, our 20x26 ($210 a month) is described on the Rent page as fitting "the contents of a four-bedroom house with some major appliances" and holding "the contents of about a 40 ft. moving van." Our 20x25 ($200) was on a waiting list when we checked.
Walk through the house and count big items first, since furniture fills a unit faster than boxes. Here is a typical 3-bedroom checklist.
If your count lands near the top of each range and you are keeping appliances, plan on a 14x20 or 15x20. If you skip appliances and the garage, a 10x25 is usually plenty.
All of our units are drive-up, ground-level units with roll-up doors, and the facility is paved with asphalt up to every unit, so you can back a moving truck right to the door. None of our 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 |
| 20x26 | 9 ft 11 in x 8 ft | 12 ft | $210 |
Measure your largest piece, usually a sectional, a refrigerator, or a tall armoire, before you choose. Anything under 7 feet 10 inches tall fits through every door on this list.
Load the heaviest and least-needed items first, at the back, and keep a walkway so you can reach boxes later. A good plan for a 10x25 or larger:
Use same-size boxes so stacks stay stable, keep heavy boxes under 50 pounds, and put pallets or plastic sheeting under anything that could pick up moisture from a concrete floor. Prop refrigerator and washer doors slightly open to prevent odors. Our guide on how to pack your storage unit for easy use has more tips.
