Boeing widens 777X cabin by four inches compared with 777‑300ER

Boeing has increased the cabin width of the 777X to 235 inches, up from 231 inches on the 777‑300ER, by using thinner fuselage sidewalls and advanced materials.

The wider cabin features an arched ceiling that eliminates centre overhead bins in premium zones, larger windows without pull‑down blinds, and a lower‑altitude pressurisation with more humid air, while offering airlines extensive customization options for sidewalls, stowage bins and ceiling treatments.
