The A350 features new composite wings with a wingspan that is common to the three proposed variants.[104] With an area of 443 m2 (4,770 sq ft)[105] the A350 features the largest wing of a single-deck widebody aircraft in production;[95] this is to be surpassed by the in-development Boeing 777X which is planned to have a wing area of 466.8 m2 (5,025 sq ft).[106] The wingspan of 64.8 m (213 ft)[105] is 4.5 m (15 ft) greater than that of the A330. This is the same span as that of the longer-range variants of the Boeing 777, which have slightly less area.[107] The A350's new wing has a 31.9° sweep angle,[105] helping to increase typical cruise speed to Mach 0.85 and maximum operating speed to Mach 0.89. The A350-1000 have a wing design with about a 4% increase in surface area.
