Section 01
What a 10x30 Storage Unit Actually Is
When you need serious space, the 10x30 is the largest standard size we rent. It is essentially a long garage you do not have to attach to a house: roomy enough to hold a large family home, or a vehicle and household goods together, or a small business's entire inventory.
A 10x30 measures 10 feet wide by 30 feet deep: 300 square feet of floor, or a rectangle 120 inches by 360 inches. With 8-foot ceilings that gives you 2,400 cubic feet, three times a 10x10 and half again a 10x20.
The Unit in Three Dimensions
Square footage undersells a storage unit, because what you are renting is volume. Both cutaways below show the same 10x30 at the same scale. The only difference between them is how the boxes are stacked.
Stacked five layers high
One layer on the floor
That is the whole argument for packing vertically. The two drawings are the same rented space at the same price, and the one on the left holds five times as much. Most people use about 40 inches of a 96-inch ceiling, and pay for the rest either way.
The Floor, Drawn to Scale
Looking straight down, here is the floor of a 10x30 at true proportion, drawn with the depth running left to right and the door on the left wall, with one layer of 18-inch medium moving boxes across it. Six fit across the 120-inch width and twenty run down the 360-inch depth, giving you a hundred and twenty per layer.
360 in / 30 ft deep · door on left wall
A hundred and twenty medium boxes per layer. Five safe layers gives you about 600 boxes, if the unit holds nothing else.
Long, Not Wide
Note the proportion. A 10x30 has three times the floor of a 10x10 but exactly the same width. Every extra square foot arrives as length, which matters more than the headline number suggests.
It means a 10x30 is excellent for a vehicle plus a household stored behind it, and poor for anything that needs to be wide. It also means the back of the unit is thirty feet from the door, so how you load it determines whether you can use it.
Bigger Than the Biggest Truck
A 26-foot moving truck, the largest most companies rent, holds roughly 1,680 cubic feet. A 10x30 holds 2,400. There is no single truck that fills this unit, which is a useful thing to know before moving day: if you are filling a 10x30 from a house, plan on more than one load or more than one vehicle.
Our moving truck size guide covers capacities.
Why You Will Never Get All 2,400 Cubic Feet
A 10x30 packed with uniform boxes reaches roughly 75 to 80 percent of its theoretical volume. One packed with mixed household furniture lands closer to 55 to 65 percent, and leaving a full-length aisle, which at this depth you should, costs roughly another 30 percent.
Section 02
What Fits in a 10x30 Storage Unit
Moving boxes are fairly consistent across manufacturers. A small book box is 16 by 12 by 12 inches (about 1.5 cubic feet), a medium is 18 by 18 by 16 inches (about 3 cubic feet), and a large is 18 by 18 by 24 inches (about 4.5 cubic feet).
Each medium box is 16 inches tall against a 96-inch ceiling. Six layers would reach it exactly, but stacking to the full 8 feet is neither safe nor practical for one person working alone. Five layers puts your top box at 80 inches, which is realistic.
A Four to Five Bedroom Home
- The complete contents of a four to five bedroom house
- Multiple living room sets: sofas, sectionals, recliners and tables
- Several bedroom sets including king mattresses, dressers and armoires
- Full dining room sets with table, chairs and china cabinet
- Major appliances: refrigerators, freezers, washers, dryers, dishwashers and ovens
- A full garage of tools, workbenches, lawn equipment and yard furniture
- 150 to 200 medium boxes on top of all of it
A Vehicle and a Household Together
This is the combination that makes a 10x30 worth its price, and the reason to choose it over a 10x20. Park a car in the front 16 to 18 feet and you still have 12 to 14 feet of depth behind it for a full household, stacked to the ceiling.
Load the household first, at the back, then drive the vehicle in last. Doing it the other way round means unloading the car every time you need a box.
Which Vehicles Fit
- Any passenger car, including full-size sedans at 200 to 210 inches, with 12 feet to spare.
- Full-size pickups, including crew-cab and extended-bed models up to about 250 inches.
- Full-size SUVs and passenger vans, subject to door opening height.
- Boats on trailers up to about 26 to 28 feet overall, measured including the trailer tongue.
- Travel trailers and pop-ups under about 28 feet, subject to height.
- Two motorcycles or ATVs plus a household, easily.
Height Is the Constraint, Not Length
At 30 feet of depth, very few vehicles are defeated by length. What defeats them is the roll-up door opening, which is lower and narrower than the 8-foot ceiling. Tall SUVs, vans with roof equipment, boats on trailers and anything with a tower or radar arch all need the door height confirmed at the specific facility before booking.
Our vehicle storage page covers requirements: proof of current registration and proof of insurance. Motorised vehicles must be operable; towable trailers, including travel trailers, fifth wheels, pop-ups and utility trailers, need not be.
Shelving Capacity
A 10x30 has 80 linear feet of wall, minus the door opening, leaving roughly 74 usable feet. Shelving along both long walls and the back gives you 70 linear feet of run, and at five shelves high that is about 350 linear feet of shelf with a full-length aisle. Our business storage page covers commercial use in more depth.
Section 03
What Does Not Fit in a 10x30 Storage Unit
This is the largest standard size we rent, so the limits that remain are specific ones.
Still Beyond This Size
- Full-size Class A motorhomes, and any RV longer than about 28 to 30 feet. Height usually rules them out before length does.
- Two vehicles side by side. The unit is 10 feet wide. Two cars will not sit beside each other at any depth, though two can sit nose to tail.
- Box trucks, large commercial vehicles and semi cabs.
- Anything taller than the door opening, which is lower than the 8-foot ceiling.
- Anything wider than about 9 feet, since the door is narrower than the unit.
- A large estate with multiple oversized collections. Two units are sometimes the honest answer.
Vehicles and Prohibited Items
- Vehicles without documentation. Storing a vehicle requires proof of current registration and proof of insurance. Motorised vehicles must be operable; towable trailers need not be.
- Flammable, combustible or hazardous materials: gasoline, propane tanks, paint, solvents, fireworks, ammunition.
- Perishable food, or anything that attracts pests.
- Living things, including plants and animals.
- Anything illegal or stolen.
- Anything you cannot afford to be without. A storage unit is not a safe deposit box.
When a Parking Space Beats a Unit
If the only thing you are storing is a large vehicle, an enclosed unit is often the wrong product. Dedicated RV, boat and vehicle spaces are sized by length rather than by unit footprint, they have no door opening to squeeze through, and they cost less than a 10x30. We offer them at many locations, including covered parking at select sites.
Rent a 10x30 when you need to store a vehicle and belongings, or when enclosure genuinely matters. See our RV storage and boat storage pages.
Our full storage FAQs cover prohibited items in detail, and your rental agreement is the controlling document. If you are storing anything unusual or high in value, read the agreement rather than relying on a general guide, including this one.
Section 04
Who a 10x30 Storage Unit Is Right For
Families Storing a Whole Large Home
A four or five bedroom house, including the garage, the patio and the loft. This is the size that takes everything in one place rather than splitting a household across two units.
Cross-Country Movers Staging Belongings
Long-distance moves rarely complete in one step. A 10x30 holds a full household while you find a permanent place at the other end, on month-to-month terms so you are not committed to a timeline you do not control yet.
Anyone Storing a Vehicle and a Household
The combination case, and the clearest reason to choose this size over a 10x20. Car at the front, household behind it, one rental, one gate code.
Military Families on Extended Deployment
A long posting or an overseas assignment often means storing an entire household and one or more vehicles for a year or more. We follow the Servicemembers Civil Relief Act, with active duty verification at signup, and we have facilities near military installations in Texas, Arkansas, North Carolina and South Carolina.
Businesses Operating Out of Storage
Twelve to fifteen pallet positions, 350 linear feet of shelf, a work vehicle and 24/7 access. For contractors, event companies, distributors and growing online retailers this is frequently the alternative to a first commercial lease, without the term commitment.
Estate Clearances and Probate
When a large family home has to be emptied under time pressure, a 10x30 takes the contents in one move so the property can be listed while decisions are made. Our storage scenarios pages cover these situations in more depth.
Section 05
How to Know If You Should Size Up or Down
There Is No Standard Size Above This One
The 10x30 is the largest standard unit we rent, so sizing up means either a second unit or a different product. That makes getting this decision right worth a little more effort than usual.
The Truck Test Does Not Work Here
A 26-foot truck holds about 1,680 cubic feet and a 10x30 holds 2,400, so no single rental truck fills this unit. Count rooms instead: four to five bedrooms including a garage, or a vehicle plus a household, is a 10x30.
You Need Something Else If Any of These Are True
- You are storing a full-size RV or a boat over about 28 feet, which wants a dedicated space sized by length
- You need two vehicles stored with access to both
- Your inventory needs more than 15 pallet positions
- You are storing a large estate with multiple oversized collections
- The item is taller or wider than the door opening, whatever its length
Size Down to a 10x20 If Any of These Are True
- You are storing a household or a vehicle, but not both
- You have three to four bedrooms rather than five
- The garage contents are staying where they are
- A single 26-foot truck load would cover it
- You are currently in a 10x30 with a third of it empty
Two Units Are Sometimes Better Than One
At this size it is worth checking whether two smaller units cost less than one large one at the facilities near you, because the per-square-foot curve does not always run in the obvious direction at the top of the range.
Two units also let you separate things you need from things you do not, which on a long rental can be worth more than the price difference. For a business serving a wide area, two units in different places will usually beat one in the middle.
Our storage size calculator builds a recommendation from an item-by-item inventory, and the size guide shows every size side by side.
Section 06
How to Pack a 10x30 Storage Unit Efficiently
Thirty feet is a long way from the door. More than at any other size, what you can use of a 10x30 is decided by the order you load it in rather than how tightly you pack.
-
Write the Load Order Down Before Moving Day
At this depth an unplanned load will bury something you need within the first hour. Decide what goes at the back, the middle and the front before the truck arrives, and tell whoever is helping.
-
If a Vehicle Is Going In, It Goes In Last
Load the household at the back first, then drive the vehicle in. Reversing that order means moving the car every time you want a box, which nobody keeps doing for long.
-
Keep a Full-Length Aisle, Without Exception
A 24 to 30 inch aisle from door to back wall costs roughly 30 percent of capacity and is the difference between a usable unit and a wall of boxes with thirty feet of unreachable space behind it.
-
Build in Zones and Keep a Map
Divide the unit into thirds and treat each as a zone: never needed, occasionally needed, and current. Photograph each zone as you finish it. On a rental this size, running for a year or more, a phone photo saves hours.
-
Appliances and Heavy Furniture at the Very Back
They are the least likely things to be needed and the sturdiest platforms to stack against. Defrost and dry refrigerators and freezers first and leave the doors ajar.
-
Flat Things Vertical Along the Long Walls
Mattresses, sofas on end, table tops, headboards, mirrors and artwork on edge against the 30-foot walls. At this length that is a great deal of storage that costs almost no floor depth.
-
Disassemble Everything and Fill Every Hollow
Five bedrooms of assembled furniture does not fit in a space that five bedrooms of flat-packed furniture fills comfortably. Drawers, suitcases, coolers, appliances and cabinets are volume you have already paid for.
-
Prepare Fuel-Powered Equipment Before It Goes In
Drain mowers, generators, trimmers and chainsaws. Fuel, propane and other flammable liquids are not permitted in a unit at any size.
-
Cover Everything and Raise the Bottom Layer
Furniture pads over wood and upholstery. Pallets or plastic risers under the bottom layer protect against incidental moisture on a concrete slab, which matters more on a long rental than a short one.
Our full storage tips guide goes further on protecting furniture and preparing appliances for storage.
Section 07
Climate-Controlled or Standard: Which 10x30 to Choose
We offer 10x30 units in both standard and climate-controlled configurations, though availability varies by location.
Standard Unit
Enclosed and secure, keeping weather and direct sun off your belongings. Interior temperature tracks the outside temperature, which across much of our footprint means summer highs well above 100 degrees inside and winter lows below freezing.
Fine for:
- Hand tools, yard equipment and hardware
- Plastic totes of household goods and holiday decorations
- Camping, sports and outdoor gear
- Metal shelving, patio furniture and durable goods
- Short-term storage over a mild season
Climate-Controlled Unit
Temperature-regulated, holding an interior temperature range year round. That protects belongings from the extreme heat and hard freezes that warp wood, crack vinyl, degrade adhesives and damage electronics.
Worth it for:
- Electronics, computers and anything with a battery or screen
- Wood furniture, especially antiques and veneered pieces
- Mattresses and upholstered furniture in long-term storage
- Vinyl records, film, photographs and artwork
- Leather goods and musical instruments
An Honest Limitation Worth Knowing About
Climate control at our facilities means temperature regulation. It does not mean moisture management, and we do not want anyone assuming otherwise on the strength of the name.
This matters because temperature and moisture are two different threats. If you are storing something genuinely moisture-sensitive, such as photographs, paper records, leather, instruments or textiles, a temperature-regulated unit addresses one of those threats and not the other. Take your own precautions for the second: seal items in airtight plastic bins rather than cardboard, add desiccant packs inside the containers, and keep everything off the concrete floor on a pallet or riser. Those steps cost very little and do more for moisture-sensitive items than any unit type will.
We would rather tell you this now than have you discover it later.
More detail on how our temperature-regulated units work is on the climate-controlled storage page.
Section 08
What a 10x30 Storage Unit Costs and How to Think About Value
What a 10x30 costs depends on your market, the specific facility, whether the unit is climate-controlled, and what is available when you book. Rather than publish a range that goes stale, we point you at live pricing for the locations near you.
The Cost Logic That Does Not Change
Prices move. The underlying economics do not, and they are worth understanding before you choose.
- Larger units cost less per square foot. Consistently, across the industry. A 10x30 costs more per month than a 10x20 and less per square foot.
- The gap between adjacent sizes is smaller than the gap in capacity. Stepping up to a second unit buys considerably more space than it costs. If you are genuinely uncertain about your inventory, that arithmetic favors sizing up.
- Oversizing is a real cost too. Half-empty units are common, and the fix is easy under month-to-month terms. If you have been paying for space you do not use, change it.
- The expensive mistake is undersizing. A mid-rental swap means renting a truck twice, moving everything twice, and losing a day. That cost dwarfs several months of the difference between two unit sizes.
At This Size, Check Two Units Against One
The per-square-foot curve does not always keep falling at the top of the range, and availability at this size is more limited than at smaller ones. Before booking, price a 10x30 against two 10x15s at the locations near you.
One unit is simpler. Two are sometimes cheaper, and let you keep what you need separate from what you do not. Neither answer is always right, which is why it is worth ten minutes.
What Is Included
Every rental includes a free lock, month-to-month terms with no long-term contract, and 24/7 gate access at nearly all of our locations. A protection plan is required at checkout at all of our facilities. Before you select one, check whether your existing homeowner's or renter's policy already extends coverage to belongings stored off premises, and read your rental agreement for what the plan does and does not cover.
One Thing We Cannot Do
Our facilities are fully automated and unstaffed. You rent online, receive your gate code by email and text, and go straight to your unit. There is no office visit and no appointment.
That model is also why we cannot accept deliveries on your behalf. There is nobody on site to receive them. If your storage plan depends on someone accepting a shipment, a 10x30 with us is not the right fit, and it is better to know that before you book. More on how our facilities operate is on the why choose 10 Federal Storage page.
10x30 Storage Unit, Frequently Asked Questions
A 10x30 storage unit is 10 feet wide by 30 feet deep, for 300 square feet of floor space. With 8-foot ceilings that comes to 2,400 cubic feet of total volume. It is the largest standard unit size we rent.
About 600 medium moving boxes stacked wall to wall, five layers high, with nothing else in the unit. Leave a full-length aisle and the figure is 415 to 425. Alongside a five-bedroom home's furniture, plan on 150 to 200 boxes.
Usually yes, including the garage contents. A 10x30 takes several bedroom sets, multiple living room sets, a dining room, major appliances, tools and yard equipment, plus 150 to 200 boxes.
Yes, and this is the main reason to choose a 10x30 over a 10x20. Park the vehicle in the front 16 to 18 feet and you still have 12 to 14 feet of depth behind it. Load the household first at the back, then drive the vehicle in last.
Only smaller ones. Travel trailers and pop-ups under about 28 feet may fit, but full-size Class A motorhomes will not, and height is usually the constraint before length because the door opening is lower than the ceiling. For RVs, a dedicated space sized by length is the better product.
A boat on a trailer up to about 26 to 28 feet overall will fit, measured including the trailer tongue rather than just the hull. Confirm the door opening height for anything with a tower, radar arch or tall console.
Not side by side, since the unit is only 10 feet wide. Two vehicles can sit nose to tail within 30 feet of depth, but you will not be able to move the one at the back without moving the one in front.
Yes. Even crew-cab, extended-bed pickups at around 250 inches fit within 360 inches of depth with room to spare. Confirm the door opening height, which is the usual constraint for tall vehicles.
Our 10x30 units have 8-foot ceilings, which is where the 2,400 cubic foot figure comes from. The roll-up door opening is lower than the ceiling, so confirm door dimensions for tall items.
More than one load. A 26-foot truck, the largest most companies rent, holds roughly 1,680 cubic feet against a 10x30's 2,400. Plan on two trips or two vehicles if you are filling the unit.
Twelve to fifteen standard pallets on the floor with room to move between them, and considerably more if racked. A standard pallet is 48 by 40 inches against a 120 by 360 inch floor.
It depends on price and availability at the locations near you, and it is worth checking rather than assuming. One unit is simpler; two can be cheaper and let you separate what you need from what you do not. For a business covering a wide area, two units in different places usually beats one in the middle.
It depends what is going in it. Choose a temperature-regulated unit for electronics, wood furniture, upholstery and mattresses in long-term storage, photographs, artwork, documents, leather and instruments. A standard unit is fine for tools, lawn equipment, plastic bins and outdoor gear. Our climate-controlled units regulate temperature only, so pack moisture-sensitive items in sealed containers either way.
Nearly all of our locations offer 24/7 gate access. Your gate code is sent by email and text when your rental is confirmed. Our facilities are unstaffed and fully contactless, so there is no office to visit and no appointment needed.
Reserve a 10x30 Storage Unit Near You
