Boeing’s new 777X set to surpass Airbus A350 in cabin width

Since its launch, the Airbus A350 XWB (Xtra Wide Body) has been recognized for its wide twin-aisle cabin. However, Boeing’s upcoming 777X is set to surpass the A350 in internal cabin width, which may change how airlines and passengers view widebody comfort.

Widebody aircraft are often compared by their internal cabin width rather than just length or wingspan. This measurement affects seat arrangements, aisle size, and overall passenger comfort. The A350 was designed with a focus on maximizing usable space inside the fuselage, providing about 5.61 meters (approximately 18.4 feet) of internal width at armrest level. Most airlines use a 3-3-3 seating layout in economy class on the A350.

Boeing has focused on increasing cabin width for the 777X by redesigning sidewalls and insulation without significantly changing the external fuselage dimensions. The company states that the new design provides an internal cabin width of about 5.97 meters (about 19.6 feet), according to Runway Girl Network. This makes it wider than both previous versions of the Boeing 777 and the Airbus A350.

The extra width achieved in the 777X comes from thinner wall structures and insulation as well as modified sidewall framing, according to Aircraft Interiors International. This allows airlines flexibility in how they use additional space—whether for wider aisles, larger seats, or more seats per row.

How much passengers benefit from these changes will depend largely on airline choices regarding seating configuration. For example, while both aircraft can support a 10-abreast layout in economy class, seat widths on the 777X can be around 18 inches even at maximum density—slightly wider than some tight layouts possible on the A350.

Cabin width is only one factor influencing passenger experience; other aspects include ceiling height, lighting design, window size and placement, air quality features such as humidity and pressurization levels, and noise reduction measures. Both manufacturers have made improvements in these areas over time.

Airbus has responded to market trends by introducing updates to its A350 cabins under what it calls the New Passenger Standard variant. These changes involve tweaks to layout and weight that may allow for tighter seating configurations if required by airlines but do not match the overall internal width gain seen in Boeing’s new model.

Aircraft performance depends on multiple factors beyond just interior space; increases in cabin width add structural complexity and weight that can affect fuel efficiency or soundproofing needs. The composite fuselage of Airbus’s A350 remains a strength for operational costs and reliability.

In terms of fleet planning, airlines will have to weigh whether added comfort or higher capacity aligns better with their business models as they consider future purchases between these two widebody types.

As Boeing markets its 777X as "wider than the competition," this could influence airline branding strategies focused on comfort features like seat size or aisle space rather than simply total capacity figures.

"The true test will come once the 777X enters service and airlines reveal how they configure it, and how passengers respond in practice."
