Quick Reference Tips
- Standard Unit: 10ft Wide x 20ft Deep x 8-12ft High.
- Clearance: Leave at least 1 foot behind the bumper for door opening/access.
- Height Check: Verify ceiling obstacles (lights/pipes) before driving in.
You are standing in the parking lot of a self-storage facility, holding a key to a 10x20 storage unit. You have a mid-size SUV like a Toyota RAV4 or a Honda CR-V. The question is simple but critical: will it actually fit? The short answer is yes, for most standard SUVs, but with very little wiggle room. A 10x20 unit offers exactly 200 square feet of floor space. Most compact and mid-size SUVs measure between 17 and 19 feet in length. That leaves you with 1 to 3 feet of clearance at the front or back. If you drive a full-size SUV like a Chevrolet Tahoe or a Ford Expedition, which often exceed 20 feet in length, you are out of luck unless you remove the spare tire or accept that the door won't close properly.
But fitting isn't just about length. It is about maneuverability, height clearance, and what else you plan to store alongside the vehicle. Let's break down the exact numbers so you don't waste money on a unit your car can't enter, or worse, damage your paintwork trying to squeeze it in.
The Math Behind the Fit
Storage units are measured from wall to wall, including the interior width and depth. A 10x20 unit gives you 10 feet of width and 20 feet of depth. This seems generous until you account for the turning radius and the physical footprint of the vehicle. An average mid-size SUV has a wheelbase of around 105 inches (8.75 feet) and an overall length of roughly 180 inches (15 feet). Wait, that sounds easy, right? Not quite. Many modern SUVs have grown significantly. A Hyundai Palisade, for example, stretches to nearly 19.7 feet. Add in side mirrors, which extend the width by another 6-8 inches per side, and you see why precision matters.
Vehicle Type Average Length Average Width (w/ Mirrors) Fit in 10x20? Compact SUV (e.g., Mazda CX-5) 17.5 ft 7.5 ft Yes, with ample room Mid-Size SUV (e.g., Jeep Grand Cherokee) 19.1 ft 7.8 ft Tight fit, minimal buffer Full-Size SUV (e.g., Chevy Suburban) 22.5 ft 8.2 ft No, exceeds length Luxury Crossover (e.g., BMW X5) 19.4 ft 7.6 ft Very tight, check mirrors
As the table shows, the dividing line is sharp. Anything under 19 feet fits comfortably. Anything over 20 feet simply does not go in. The gray area is between 19 and 20 feet. Here, you need to consider the door swing. Can you open the driver's side door if the unit is pushed against a wall? In many facilities, the aisle width outside the unit restricts how far you can pull forward before turning. If your unit door opens fully, you might get away with it, but you risk dinging the bumper against the roll-up door track.
Height Clearance Matters More Than You Think
Length gets all the attention, but height is the silent killer of good plans. Standard storage units usually have ceilings ranging from 8 to 12 feet. However, the effective height is lower because of sprinkler systems, lighting fixtures, and ventilation ducts hanging from the ceiling. If you have a lifted SUV, such as a Jeep Wrangler with a 4-inch lift kit, or a vehicle with a roof rack loaded with cargo boxes, you need to measure vertically.
A stock SUV is typically 5.5 to 6 feet tall. Add a roof box, and you might hit 6.5 or 7 feet. If the unit has low-hanging lights at 6.8 feet, you cannot park underneath them. Always ask the facility manager for the minimum clear height inside the unit. Do not rely on the advertised "high ceiling" label without verifying where the obstacles start. I once saw a customer try to force a lifted truck into a unit with exposed pipes, only to realize halfway in that the snorkel intake was scraping the metal beam above.
Maneuvering Into the Unit
Fitting the car inside is one thing; getting it there without scratching your rims is another. Storage aisles vary in width. Some older facilities have narrow corridors that make turning a large SUV difficult. Before you rent, visit the site during off-peak hours. Drive through the aisles. Check the turning radius required to enter the specific unit number you want. Is it a corner unit? Corner units often have better access angles than those buried deep in a row.
If you are storing the car alone, you can position it centrally. But if you plan to stack boxes along the sides, remember that a 10-foot width minus two 2-foot stacks leaves only 6 feet for the car. That is barely enough for the body plus mirrors. You lose the ability to open doors easily. If you need to access the trunk frequently, leave at least 3 feet of clearance behind the rear bumper. This allows you to walk around the back and load groceries or camping gear without climbing over tires.
What Else Fits With an SUV?
People rarely store just a car. They use the space as a secondary garage. With a mid-size SUV taking up most of the 10x20 footprint, your remaining space is limited. You might fit a small motorcycle sideways behind the SUV if there is 4 feet of depth left. Alternatively, you could stack pallets of household goods on the passenger side if you keep the driver's side clear for entry and exit.
Consider vertical storage. Use the walls to hang bicycles, lawnmowers, or tools. This frees up floor space. However, do not overload the shelves near the ceiling if the unit is prone to temperature fluctuations. Metal parts can rust, and cardboard boxes can soften in humidity. For long-term vehicle storage, especially in London's damp climate, moisture control is vital. Ensure the unit is dry and consider using a dehumidifier if the facility allows electrical outlets.
Alternatives When an SUV Doesn't Fit
If your SUV is too large for a 10x20, do not force it. Renting a larger unit saves headaches. A 10x30 unit provides 300 square feet, offering comfortable room for a full-size SUV plus several rows of shelving. The cost difference is usually marginal compared to the risk of damaging your vehicle or struggling to move items in and out.
Another option is indoor versus outdoor storage. Outdoor units often have higher ceilings and wider doors, making them easier to navigate for taller vehicles. However, they expose your car to weather elements. Indoor units offer protection but tighter constraints. Weigh the value of your vehicle against the convenience of the space. If you own a classic car or a luxury SUV, the extra cost for a 10x30 indoor unit is a worthwhile insurance policy against dents and dust.
Practical Checklist Before You Sign
- Measure Your Vehicle: Include mirrors and any aftermarket additions like bike racks or lift kits.
- Check Door Swing: Can you open the doors if the car is centered? Or do you need offset parking?
- Verify Ceiling Height: Ask specifically about the lowest obstruction point inside the unit.
- Test the Approach: Drive through the aisle to ensure you can turn into the unit without hitting adjacent walls.
- Plan Access Routes: Decide if you need to reach the trunk regularly. Leave clearance accordingly.
Can I fit a pickup truck in a 10x20 unit?
Generally, no. Most pickup trucks, even compact ones like the Ford Ranger, are longer than 20 feet when considering the bed and cab combined. Mid-size and full-size trucks definitely require a 10x30 or larger unit. Only very small mini-trucks might fit, but they would take up almost the entire space.
Do I need insurance for my car in a storage unit?
Yes, most storage facilities require proof of insurance for vehicles stored on-site. Standard home contents insurance often excludes vehicles parked in external storage units. You may need comprehensive auto insurance or a specialized storage insurance policy to cover theft, fire, or accidental damage while the car is in the unit.
How much does it cost to store an SUV in London?
Prices vary widely based on location and security features. As of late 2026, expect to pay between £150 and £250 per month for a 10x20 unit in Greater London. Central locations command higher prices, while outer boroughs may be cheaper. Always check for admin fees and whether VAT is included in the quoted price.
Should I put a tarp over my SUV in storage?
It depends on the unit type. In an indoor, climate-controlled unit, a breathable car cover is sufficient to protect against dust. In an outdoor unit, a heavy-duty, waterproof tarp is essential to shield against rain, bird droppings, and UV rays. Avoid plastic tarps that trap moisture against the paint, which can cause mold or water spots.
Can I work on my car in the storage unit?
Most facilities prohibit mechanical work involving fluids like oil changes or brake bleeding due to spill risks. Light maintenance, such as changing wipers or checking tire pressure, is usually allowed. Always check the facility's specific rules regarding repairs and fluid disposal to avoid fines.
