Both the Boeing 777 and Airbus A350 are large wide-body aircraft, but their size comparison depends on the specific variants. Here's a breakdown:
Length:
777-200: 63.7 m (209 ft 1 in)
777-300: 73.9 m (242 ft 4 in)
777X (777-9): 76.7 m (251 ft 9 in)
Wingspan:
777-200/-300: 60.9 m (199 ft 11 in)
777X: 71.8 m (235 ft 5 in) (foldable wingtips)
Capacity: 314–426 passengers (depending on variant and configuration)
Length:
A350-900: 66.8 m (219 ft 2 in)
A350-1000: 73.8 m (242 ft 1 in)
Wingspan:
All variants: 64.8 m (212 ft 7 in)
Capacity: 300–410 passengers (depending on variant and configuration)
Length:
The 777-9 (longest 777 variant) is longer than the A350-1000.
Wingspan:
The A350's wingspan is larger than the classic 777 but smaller than the 777X.
Passenger Capacity:
The 777 generally has a higher maximum passenger capacity compared to the A350.
In summary, the Boeing 777-9 is the largest among these aircraft in terms of length and capacity. However, the A350 offers a slightly larger wingspan than earlier 777 models, but not the 777X.
