The facility manager at the Jones Rd. location is everything! I signed up to rent a 10x20 storage online and she returned my call in less than 15 minutes. She walked me through the rest of the rental agreement. I’ve never had so much fun or laughter completing a contract. Before I knew it, I had and access code in my email inbox and we were good to go. Whole process took about 15 minutes or less. Whoever reads these…she is top notch!

While similar, sizing up from a 10x20 to a 10x25 storage unit adds 50 square feet and 400 cubic feet of additional space for around $40 more per month, which helps accommodate larger storage needs. The extra room means a 10x25 unit can accommodate larger vehicles like full-size trucks or cargo vans, as well as leave space for walkways that make it easier to access items.

The difference between a 10x25 and a 10x30 storage unit is an additional 50 square feet and 400 cubic feet for around $40 more per month. A 10x30 unit provides additional space for 4-5 bedrooms, as well as walking room around a vehicle or additional storage items. Our 10x25 units resemble a large one-car garage, while a 10x30 unit is more comparable to a 1.5-car garage.
The monthly pricing difference referenced above reflects national averages and is subject to change based on location, availability, and current promotions. For accurate, real-time pricing, please navigate to the facility page or call your nearest Extra Space Storage location.
What Typically Fits in a 10x20 vs 10x25 vs 10x30 Storage Unit?
While all three unit sizes can offer storage for large items, the larger your storage unit, the more items you'll be able to store. However, there are some common items that only a 10x30 storage unit can fit—like trucks and other large vehicles. Check out these examples of what kinds of items fit in each large storage unit size.
Item compatibility is based on standard dimensions and is intended as a general guide only. Whether your items fit will depend on their actual measurements, quantity, and how they are arranged within the unit. We recommend measuring your items before selecting a unit size.

Which Is Best for You: A 10x20, 10x25, or 10x30 Storage Unit?
A 10x20 or 10x25 unit may be best for you if you have fewer items and a small or medium-sized vehicle to store, while a 10x30 will better suit those with a high volume of items and who need to store full-size trucks, vans, or small RVs and boats. Explore more benefits and use cases of each size below.

How to Choose the Right Storage Unit Size
Tips for Choosing:
Take Inventory: Document everything you need to store.
Measure Your Items: Measure larger belongings like sofas, beds, dining tables, appliances, boxes, and any oversized items to make sure you rent a big enough unit.
Test the Space: Use painter's tape to map out spaces with each unit size's dimensions to see if your items will fit.
Remember to Stack: Most storage units offer 8-foot ceilings, though select locations may offer higher ceilings—stack items and boxes to see how you can maximize vertical space.
Create Walkways: While planning your layout, include walking space inside the unit so you can easily access your belongings.
Upgrade if Unsure: It's usually better to choose the next size up if you're unsure about unit sizes—especially with large storage units used for full household moves or vehicles.
Additional Considerations:
Accessibility: If you expect to make frequent visits to your units, a 10x25 or 10x30 may be better since they allow for wider walkways and easier access to stored items.
Climate Control: For temperature-sensitive belongings, storage units with climate control can help protect against extreme temperatures and humidity.
Drive-Up Access: If you're storing heavy furniture, equipment, or vehicles, drive-up units streamline the loading and unloading process.
Vehicle, RV, & Boat Storage: Make sure to measure the dimensions of your recreational vehicle, camper, or boat beforehand to select the right unit or parking space for it.

Getting everything set up for our 10x25 unit was really easy. The person at the front desk who helped us out was really friendly about it and fast. He showed us where the unit was, even helped us visualize it on a map for us to find the unit if we needed. Very clean and quiet, and it seemed like security was good.

The largest standard storage unit size is typically a 10x30, offering 300 square feet of space—roughly equivalent to 1.5 car garage. Some facilities may also offer oversized or specialty units, but 10x20, 10x25, and 10x30 are the most common large storage unit sizes used for full household moves, vehicles, and business storage.
Which unit size is best for storing the contents of my home?
While a 10x20, 10x25, and 10x30 storage unit can hold the contents of multiple bedrooms, the best option will depend on the amount of furniture, appliances, and household items you have. Generally, we recommend a 10x20 unit for a two-bedroom home, a 10x25 unit for a three-bedroom home, and a 10x30 unit for a home with four or more bedrooms.
Which unit size is best for vehicle storage?
A 10x20, 10x25, and 10x30 can all accommodate vehicles, but the best option for you will depend on what kind of vehicle you need to store. A 10x20 storage unit is best for compact cars and sedans, while a 10x25 storage unit can hold trucks and vans. 10x30 storage units offer the most flexibility, as they can accommodate cars, trucks, SUVs, and some RVs and boats.
What are the most popular large storage unit sizes?
10x20, 10x25, and 10x30 are the most popular large storage unit sizes, with the 10x20 consistently ranking among the most rented nationwide due to its versatility. These larger units are commonly used for household moves, renovations, vehicle storage, and business inventory. Larger unit sizes able to accommodate multiple vehicles, extra large contractor equipment, or high-volume business storage may be available at select locations.
What size moving truck do I need for a 10x20, 10x25, or a 10x30 storage unit?
10x20, 10x25, and 10x30 storage units typically hold the contents of homes between 3 and 5 bedrooms, which will typically require a moving truck ranging from 17 to 26 feet, depending on your specific situation. Take into consideration how much large or bulky furniture you have and if you'll be able to stack moving boxes.
