A completely-developed goose feather has a round and blunt shape. The feather is strongly curved and its shape appears to be rather compact. At the lower end, the vane which is the whole of feather barbs intimately connected among them by means of barbules, looks as if it has been cropped.
In comparison to duck feathers, goose feathers are often bigger and stronger which comes from the size and the physique of the birds the material derived from.
A goose feather with 2.36. inches (6 cm) in length weighs about 0.0241 g. A goose feather with 3.94 inches (10 cm) in length weighs about 0.0436 g.
