The average wingspan of a golden eagle is 6 to 7.5 feet (182cm-229cm). Wingspan of an eagle depends on overall size. Eagles in northern parts of their range tend to be larger overall, including a larger wingspan.
Eagles are generally differentiated by size. The bald eagle has a wingspread of about 6 feet, the golden eagle is larger (sorry, not familiar with eagles outside the U.S.) Most eagles are quite large and their diet can be varied (bald eagles are fishers and scavangers, goldens take small game - and sometimes the babies of larger game).
