Moving from one home to another or simply trying to make more space can be stressful. One of the biggest questions families with larger homes face is: What size storage unit for a 3-bedroom house?
A three-bedroom home usually comes with more than just furniture. There are kitchen appliances, clothes, kids’ toys, outdoor equipment, and sometimes even garage tools. Picking the right storage size is not just about square feet; it’s about making sure everything fits safely without paying for space you don’t need.
This blog will guide you through the best storage unit size for a 3-bedroom house, explain costs, compare unit options, and share tips on choosing the right space.
Why Storage Size Matters?
When you’re moving or downsizing, you want your belongings to stay safe and easy to access. Choosing the wrong size can be costly. A unit that’s too small may mean stacking things unsafely or making multiple rentals. A unit that’s too big means paying for space you don’t use.
For families in a three-bedroom house or apartment, the sweet spot usually falls between a 10×10 storage unit and a 10×15 storage unit. The choice depends on how much you’re storing and how bulky your items are.
Breaking Down the Options
10×10 Storage Unit
A 10×10 storage unit is about the size of a small bedroom. It can fit furniture from two rooms, a few appliances, and around 15–20 medium boxes.
This size works well if you’re storing part of your home while renovating or if you’re moving from a 3-bedroom apartment but keeping large items in your new place.
How much does a 10×10 storage unit cost per month?
On average, you can expect to pay between $90 and $150, depending on location and whether you choose climate control.
10×15 Storage Unit
A 10×15 storage unit is larger and can hold the contents of a standard three-bedroom home. Think multiple bedroom sets, couches, dining furniture, and larger appliances. It’s often the go-to choice for families moving from a house to a smaller apartment.
This is the most recommended 3-bedroom house storage unit size for families who want one space for everything.
How much does a 10×15 storage unit cost per month?
The price typically ranges from $120 to $200 per month, again depending on location and amenities.
Storage Unit Size Guide
If you’re not sure what fits where, here’s a simple way to picture it:
- 5×5 unit: Fits small items or a closet’s worth of belongings.
- 10×10 unit: Fits two rooms. Works for small apartments or partial storage.
- 10×15 unit: Fits three to four rooms. Perfect for most three-bedroom homes.
- 10×20 unit: Fits a full house plus extras like a garage or outdoor items.
This storage unit size guide makes it easier to decide based on the number of rooms and how much furniture you have.
Cost of Renting a Storage Unit
The cost of renting a storage unit can vary depending on the unit’s size, location, and additional features such as climate control or enhanced security. On average, you can expect the following price ranges:
- A 10×10 unit typically costs between $90 and $150 per month.
- A 10×15 unit usually ranges from $120 to $200 per month.
- A 10×20 unit often falls between $150 and $250 per month.

Benefits of Renting a Storage Unit
Many families choose self-storage because it provides practical solutions to everyday space challenges. Here are some of the most common benefits:
- Flexibility during moves: A storage unit gives you the freedom to keep your belongings safe while you are in between homes or waiting to settle into your new place. This makes moving far less stressful.
- Decluttering made easy: Instead of crowding your home with items you don’t use every day, you can store them away and enjoy a more open, organized living space without having to part with the things you still value.
- Enhanced safety and protection: Most storage facilities are equipped with features such as surveillance cameras, secure locks, and controlled access, so you can feel confident that your belongings are kept in a safe environment.
- Seasonal storage solutions: A unit is the perfect place to keep holiday decorations, winter clothing, or outdoor furniture tucked away until you need them again, helping your home stay neat and clutter-free year-round.
- Extra space for larger households: For bigger families, where every square foot of the home matters, a storage unit can make daily life more comfortable by providing additional space and reducing the feeling of overcrowding.

Storage Units for Small Apartments
Not everyone needs a large unit. For smaller spaces, there are storage units for small apartments as well. A 5×5 or 5×10 is often enough to store clothes, décor, or a single bedroom’s worth of furniture.
Final Thoughts
So, what size storage unit do you need for a 3-bedroom house? For most families, the 10×15 storage unit is the perfect fit. It’s big enough for furniture and appliances, yet affordable. If you’re only storing part of your belongings, a 10×10 unit may be enough. If you need more space for outdoor or garage items, go with a 10×20 unit.
