Albatrosses vary in size, but the largest species is the wandering albatross (Diomedea exulans). With a wingspan of up to 3.63 metres (11 ft 11 in), it is one of the largest flying birds in the world, if not the largest.
The wandering albatross's wingspan exceeds that of any other living bird. Its body length can reach up to 1.35 metres (4 ft 5 in), making it the heaviest flying bird, with an average weight of 11.5 kilograms (25 lb). Some males can reach weights of up to 16.1 kilograms (35 lb).
