For a 3 bedroom home, you typically need a 10×20 storage unit (200 sq ft). If you have bulky furniture, a garage, or are storing a full household during a move, a 10×30 unit (300 sq ft) is the better choice. Most families find that a 10×20 covers all standard bedroom furniture, appliances, and boxes comfortably.
Key Takeaways
- A 10×20 storage unit is the most recommended size for a standard 3 bedroom home
- A 10×30 unit is ideal if you have a garage, basement, or large furniture pieces
- A 10×15 unit may work only if you are storing select items, not a full house
- Climate controlled storage is recommended for wood furniture, electronics, and clothing
- Always inventory your items before renting to avoid paying for too much or too little space
- Stacking items vertically and using shelving can maximize any unit size
- Prices and availability vary by location, so booking early saves money
What Size Storage Unit Is Best for a 3 Bedroom Home?
The best storage unit size for a 3 bedroom home is a 10×20. This unit gives you 200 square feet of floor space with ceiling heights typically ranging from 8 to 10 feet. That translates to roughly 1,600 to 2,000 cubic feet of usable storage space.
For most families, this size fits:
- 3 full bedroom sets including bed frames, mattresses, and dressers
- A living room sofa, coffee table, and entertainment center
- A dining table with chairs
- Kitchen appliances like a refrigerator and washing machine
- Roughly 20 to 30 medium moving boxes
If your home has a lot of outdoor equipment, a large garage, or oversized sectional furniture, you should consider going up to a 10×30. Browse our available storage unit sizes at Self Storage IA to find the right fit for your household.
How Much Space Do You Need for Furniture and Appliances?
Understanding how much space each item takes helps you choose the right storage unit size for a 3 bedroom house. Here is a rough breakdown of common furniture and appliance sizes:
Bedroom Items
- King size mattress and frame: approximately 30 to 40 sq ft
- Queen bed set: approximately 25 to 35 sq ft
- Dresser and nightstands: approximately 10 to 15 sq ft
Living Room Items
- 3 seat sofa: approximately 15 to 20 sq ft
- Coffee table and side tables: approximately 10 sq ft
- TV stand and entertainment unit: approximately 10 to 15 sq ft
Kitchen and Laundry
- Refrigerator: approximately 5 to 8 sq ft
- Washer and dryer: approximately 8 to 12 sq ft
When you add it all together for three bedrooms plus common areas, you are looking at a minimum of 150 to 200 square feet. That is exactly why a 10×20 unit is the standard recommendation for a storage unit size for a 3 bedroom home.
Can a 10×20 Storage Unit Fit a 3 Bedroom House?
Yes, a 10×20 storage unit can comfortably fit the contents of most 3 bedroom homes. The key is smart packing.
Tips to Maximize a 10×20 Unit
- Disassemble large furniture like bed frames and tables to save floor space
- Stack items vertically and use tall shelving units
- Place heavy and large items like appliances and sofas at the back first
- Use mattress bags and furniture covers to protect items and stack more efficiently
- Fill dresser drawers with smaller items like linens and clothes to save box space
Real life example: A family of four moving from a 3 bedroom house to a smaller apartment used a 10×20 unit to store their full dining set, three bedroom sets, a sectional sofa, and over 40 boxes. They fit everything in with room to walk through the middle for easy access.
According to the U.S. Census Bureau’s American Housing Survey, the average American home contains a significant amount of household goods, which is why correctly sizing your storage unit before moving is so important.
When Should You Choose a 10×30 Unit Instead?
A 10×30 unit gives you 300 square feet and is essentially the size of a one car garage. You should consider upgrading to a 10×30 when:
- You are storing items from a garage or basement in addition to bedroom furniture
- You have a large sectional sofa or oversized dining furniture
- You want a center walkway for easy access throughout the storage period
- You are running a small business and storing inventory alongside household items
- You are doing a full home renovation and need to clear out the entire house
The extra 100 square feet in a 10×30 does not cost dramatically more than a 10×20 in most markets. If you are on the fence, the larger unit gives you peace of mind and easier organization.
Is a 10×15 Storage Unit Enough for a 3 Bedroom Home?
A 10×15 storage unit gives you 150 square feet of space. For a full 3 bedroom home, this is generally not enough unless you are being very selective about what you store.
When a 10×15 Works
- 2 bedroom apartments with minimal furniture
- A 3 bedroom home where you are only storing select items, not everything
- Seasonal items, boxes, and small furniture pieces
When a 10×15 Falls Short
- Moving your entire 3 bedroom house into storage
- Storing large appliances, sofas, and multiple bed sets
- Expecting to store items long term and need easy access
If budget is a concern and you cannot fit a 10×20, consider decluttering before storing. Donate or sell items you no longer need. This approach saves you money on monthly rental fees while keeping only what truly matters.
How Do I Estimate the Right Storage Space for My Home?
Estimating the right storage unit size for your house does not have to be complicated. Follow these three steps:
Step 1: Make a Full Inventory
Walk through every room and write down every large item you plan to store. Include furniture, appliances, boxes, bicycles, and outdoor equipment. Do not guess. A written list prevents you from underestimating.
Step 2: Use a Storage Calculator
Many storage companies offer free online size calculators. You input your furniture list and the calculator suggests the right unit size. These tools are especially useful when you are unsure whether to go with a 10×20 or 10×30. If you are located in Iowa, you can contact our team at Self Storage IA for personalized help choosing the right unit size.
Step 3: Think About Access
If you plan to visit your unit regularly to retrieve or swap items, leave a walkway. A 10×20 unit packed to the ceiling with no aisle is frustrating to use. If regular access is important, either rent a larger unit or plan your layout carefully.
The FMCSA (Federal Motor Carrier Safety Administration) guide on moving recommends making a detailed inventory of your belongings before choosing a storage or moving solution, which helps you avoid paying for more space than you actually need.
Should You Choose Climate Controlled Storage for a 3 Bedroom Home?
Climate controlled storage maintains a consistent temperature and humidity level inside the unit. For a 3 bedroom household, this option is highly recommended if you are storing:
- Wooden furniture, which can warp or crack with humidity changes
- Electronics like TVs, computers, and gaming systems
- Clothing, especially leather, wool, or formal wear
- Artwork, photographs, or important documents
- Musical instruments
Standard units without climate control are typically fine for short term storage of metal furniture, tools, outdoor gear, and plastic items.
If you are storing items for more than 3 months, spending a few extra dollars per month on climate controlled storage options is well worth it. Temperature fluctuations can cause thousands of dollars in damage to wood furniture and electronics.
What Are the Most Common Storage Unit Sizes for Houses?
Here is a quick reference guide for how each unit size matches up to home sizes:
5×10 (50 sq ft)
Best for studio or small 1 bedroom apartments, seasonal items, or a single room of furniture.
10×10 (100 sq ft)
Best for 1 bedroom apartments or small 2 bedroom homes with minimal furniture.
10×15 (150 sq ft)
Best for 2 bedroom homes or selective items from a 3 bedroom house.
10×20 (200 sq ft)
Best for 3 bedroom homes, standard household moves, and full furniture with appliances.
10×30 (300 sq ft)
Best for large 3 bedroom or 4 bedroom homes, homes with a garage or basement, and full household relocations.
How Long Should You Rent a Storage Unit?
The length of your rental affects both your budget and the type of unit you choose.
Short Term (1 to 3 Months)
This is typical for people in the middle of a move or home renovation. A standard 10×20 without climate control is usually fine for this period.
Medium Term (3 to 12 Months)
This is common for military relocations, extended travel, or waiting on a new home purchase. Climate control becomes more important here, especially for wood furniture and electronics.
Long Term (Over 12 Months)
For long term storage, invest in quality packing materials, climate control, and organization. Use shelving, label every box, and create an inventory sheet that you keep outside the unit.
How Should You Pack a 10×20 Storage Unit for a 3 Bedroom Home?
Packing your unit efficiently is just as important as choosing the right size. A poorly packed 10×20 can feel cramped, while a well packed one can hold more than you expect.
Best Packing Practices
- Load large and heavy items first: appliances, sofas, and bed frames go against the back wall
- Stack boxes from floor to ceiling in uniform sizes for stability
- Place items you may need to access more frequently near the front
- Use furniture pads and stretch wrap to prevent scratches
- Store mattresses on their side or use a mattress bag and lay flat on top of other items
- Keep a detailed inventory list with a copy stored at home
What to Store Near the Door
- Seasonal decorations
- Boxes of items you may need within the first few weeks
- Tools or small appliances you might need access to
Labeling the top and sides of every box is a habit that saves hours of searching later.

Frequently Asked Questions
What Fits in a 10×20 Storage Unit?
A 10×20 storage unit fits the full contents of a 3 bedroom home including bedroom furniture, a sofa, dining table, kitchen appliances, and 20 to 30 boxes. It is the most popular choice for household moves and home renovations.
Is a 10×15 Enough for a 3 Bedroom Home?
In most cases, a 10×15 is not enough for a full 3 bedroom home. It works well if you are only storing select furniture or boxes rather than a complete household. For a full move, a 10×20 is the recommended minimum.
How Big a Storage Unit Do I Need for a 3 Bedroom House With a Garage?
If you are storing items from both the main living areas and a garage, you should choose a 10×30 unit. This gives you the extra 100 square feet needed for tools, outdoor equipment, bicycles, and seasonal items from the garage.
How Do I Estimate Storage Space for My Home?
Create a written inventory of every item you plan to store. Focus on large items first such as sofas, beds, and appliances. Then use an online storage calculator or call a local facility to help match your inventory to the right unit size.
Should I Choose Climate Controlled Storage?
Yes, climate controlled storage is recommended if you are storing wood furniture, electronics, clothing, artwork, or documents. If you are only storing metal tools, plastic bins, or outdoor gear for a short period, a standard unit may be sufficient.
What Is the Average Cost of a 10×20 Storage Unit?
The average cost of a 10×20 storage unit in the United States depending on location, facility quality, and whether climate control is included. Urban areas tend to be more expensive than rural or suburban markets.
Can I Store a Car in a 10×20 Unit?
A standard vehicle can technically fit in a 10×20 unit, but it will leave very little room for other items. If you need to store both a car and household belongings, a 10×30 unit is a much better fit.
Conclusion
Choosing the right storage unit size for a 3 bedroom home comes down to how much you are storing and how long you need it. For most families, a 10×20 storage unit is the ideal choice covering bedroom furniture, appliances, sofas, and boxes with room to spare. If you have a garage, basement, or oversized furniture, stepping up to a 10×30 unit gives you the extra breathing room you need.
Always start with a clear inventory, think about access and organization, and consider climate control if you are storing wood furniture or electronics. Planning ahead saves you money, reduces stress, and protects your belongings.
