Airbus A350 vs. Boeing 777: Which Wide-Body Jet Is Bigger?
When it comes to long-haul travel, few aircraft dominate the skies quite like the Airbus A350 and the Boeing 777. Both are modern, twin-engine, wide-body jets designed for international routes, offering cutting-edge technology, fuel efficiency, and exceptional passenger comfort. But when comparing the two, one question comes up often: Is the Airbus A350 bigger than the Boeing 777?
The short answer is: No, the Boeing 777 is generally larger. But the comparison isn’t as simple as it seems. Both aircraft families have multiple variants, and the difference in size can vary depending on the models being compared. Let’s break it down by key dimensions.
Length
The Airbus A350 comes in two main variants:
-
A350-900: 219 feet (66.8 meters)
-
A350-1000: 242 feet (73.8 meters)
The Boeing 777 has a few variants as well:
-
777-200: 209 feet (63.7 meters)
-
777-300: 242 feet (73.9 meters)
-
777X (777-9): 251 feet (76.7 meters)
The A350-1000 and 777-300 are nearly identical in length, but the new 777X is currently the longest passenger aircraft in the world, surpassing both A350 models.
Wingspan
This is where it gets interesting.
-
A350-1000 wingspan: 212 feet (64.8 meters)
-
777-300ER wingspan: 213 feet (65 meters)
-
777X wingspan: 235 feet (71.8 meters) with extended wingtips
The Boeing 777X again takes the lead here, thanks to its folding wingtips which allow it to fit into standard airport gates while maximizing lift in the air.
Passenger Capacity
Passenger capacity depends on airline configuration, but here are the typical ranges:
-
A350-900: 300–350 passengers
-
A350-1000: 350–410 passengers
-
777-200: 314–396 passengers
-
777-300: 368–451 passengers
-
777X: Up to 426 passengers in a typical layout
The 777 family, especially the 777X, generally offers a higher seating capacity than the A350 series.
Cargo and Payload
The Boeing 777 also leads in cargo space, which is why it’s widely used for both passenger and freight operations. The 777F (freighter version) is one of the most popular cargo aircraft in the world. While Airbus does have the A350F in development, it’s still catching up in that department.
Technology and Efficiency
While the 777 is bigger, the A350 is often praised for its advanced materials and fuel efficiency. Built with over 50% carbon-fiber-reinforced polymer, the A350 is lighter and more efficient than many older aircraft. It also features one of the quietest cabins in the industry and has a slightly higher cruising altitude.
The 777X, however, includes several technological upgrades to close that gap, including improved GE9X engines and a redesigned wing.
Conclusion
So, is the Airbus A350 bigger than the Boeing 777? In most cases, no. The Boeing 777, especially the 777X, edges out the A350 in length, wingspan, and passenger capacity. That said, the A350 holds its own with a sleek design, superior fuel economy, and cutting-edge cabin comfort.
Ultimately, both aircraft represent the best of modern aviation, and airlines often choose between them based on route structure, fuel needs, and passenger preferences. Whether you’re flying in an A350 or a 777, you’re in for a top-tier travel experience.
