Wingspan is the distance from the tip of one wing to the tip of the other, measured with the wings stretched right out. It is used for birds, bats, insects, and for . It is the standard measurement people give when they want to say how big a flying thing is: 'an albatross with a wingspan of three metres', 'the plane has a wingspan of sixty metres'. The word is neutral and slightly technical-sounding but perfectly ordinary — you will meet it constantly in nature documentaries, museum labels, and articles about planes. It is a countable noun, and the usual patterns are 'a wingspan of X' or 'an X wingspan'. People also stretch it to human arms: a basketball commentator may say a player 'has a huge wingspan', meaning his arms are long from fingertip to fingertip. That use is informal but common in sports talk.
組成wing + span. 'Span' on its own means the distance from one side of something to the other — it also gives us the span of a bridge, and 'lifespan' (the stretch of time a life covers). So wingspan = the stretch across the wings.
