Size brings a design problem the plans don’t show. Thousands of cars want to enter in the morning and leave at closing time, and every one passes a control point. The largest car parks tackle that in four places:
- Entry: many lanes working side by side, with prepaid or booked parking and number plate recognition to cut the stop at the barrier.
- Payment: pay stations on foot, payment at the exit lane, or advance booking, so nobody holds up the queue fumbling for a card.
- Finding a space: level-by-level signs that count free bays and send drivers to the emptiest decks.
- Finding the car again: themed zones, colours and numbered rows. Universal Orlando’s garages use themed sections so visitors can remember where they parked.
Behind the barriers, one system ties the entry record, the payment and the exit together, and that system decides how fast the car park empties at closing. For the operator’s view of a car park of any size, see how it works.
The 10 biggest parking lots and car parks in the world
Capacities are rounded, because counts shift as owners add decks and overflow areas.
1. West Edmonton Mall, Edmonton, Canada
About 20,000 spaces, plus an overflow lot for roughly 10,000 more. The mall has held the Guinness World Record for the largest car park since 1981.
2. Universal Orlando Resort, Florida, USA
More than 19,000 cars across two linked garages, a five-level North Garage and a six-level South Garage, covering about 3.3 million square feet. The garages serve Universal Studios, Islands of Adventure, Volcano Bay and CityWalk. Moving walkways carry visitors to a central security hub.
3. Disneyland Resort, Anaheim, USA
The Mickey and Friends structure opened in 2000 with 10,281 spaces. The Pixar Pals structure added roughly 6,000 more in 2019, taking the combined total past 16,000.
4. Seattle-Tacoma International Airport, USA
About 13,000 cars, all in a single garage under one roof.
5. Walt Disney World Magic Kingdom, Florida, USA
About 12,000 spaces in the main surface lot. Visitors park well away from the park itself and reach the gates by tram, ferry or monorail.
6. Detroit Metropolitan Airport, McNamara Terminal, USA
About 11,500 spaces stacked across ten levels, built to serve one terminal.
7. Chicago O’Hare International Airport Main Garage, USA
9,266 spaces in the main garage, set in the middle of the airport’s terminal core.
8. Toronto Pearson Airport Terminal 1, Canada
Roughly 8,400 to 9,000 spaces, depending on the count, serving Terminal 1 at Canada’s busiest airport.
9. Baltimore/Washington International Airport Daily Garage, USA
Around 8,400 spaces in a single daily parking garage.
10. Dallas Fort Worth Airport Terminal D Garage, USA
About 8,100 spaces in the garage beside Terminal D.
What the biggest car parks teach designers
The list covers malls, theme parks and airports, and the same design questions come up at each.
- Stack or spread. Airports stack parking in levels beside the terminal to keep walks short. Malls and resorts with cheap land spread outward, then deal with the distance.
- The walk is part of the design. Moving walkways, trams and monorails turn a long walk into part of the visit. Without them, a 20,000-space lot leaves some visitors a long trek from the door.
- Wayfinding is architecture. Themed zones, colours, level names and row numbers do the work that a map can’t. A good scheme helps people find their car at the end of a long day.
- Exits set the pace. The number of exit lanes and the way people pay decide how quickly the site empties, and that matters more than the bay count when everyone leaves at once.
FAQs
What is the biggest parking lot in the world? West Edmonton Mall in Edmonton, Canada. It holds about 20,000 vehicles, with an overflow lot for roughly 10,000 more, and has held the Guinness World Record for the largest car park since 1981.
What is the biggest parking garage in the world? Universal Orlando Resort’s two linked garages hold more than 19,000 cars, the largest multi-level total on this list. Seattle-Tacoma International Airport’s single garage holds about 13,000 cars under one roof.
What is the biggest parking lot in the US? Universal Orlando’s garages, with more than 19,000 spaces, followed by the Disneyland Resort’s two structures at more than 16,000.
Why are the biggest car parks at airports and theme parks? Both draw huge numbers of visitors who arrive by car, stay for hours and leave at similar times, so they need parking on a scale few other building types do.
The bigger the car park, the more design matters
The world’s biggest car parks are feats of logistics as much as construction. Their bay counts make the headlines, but each one depends on the same everyday design choices as a small one: where cars enter, how they pay, how drivers find a space and how quickly everyone gets out again. At 20,000 spaces, every one of those choices gets multiplied.
