The domestic goose is significantly larger than the greylag goose (1.5–3 times in mass). Body length 750–1100 mm, wingspan 1500–1900 mm. Head large, massive, often with a knob at the base of the beak (in Chinese and African breeds). Beak 55–85 mm, straight or slightly convex. Neck long (280–450 mm), powerful, with a dewlap in heavy breeds. Body deep, broad, barrel-shaped in meat breeds. Wings 380–520 mm, relatively short, most birds do not fly. Legs with tarsus length 90–130 mm, with well-developed webs. Tail 140–190 mm, broad, raised. Plumage dense with abundant down. Main colorations: white, gray (wild type with scaly pattern), pied, bean goose type, brown. Acceptable proportions: body length 1.6–2.0 times neck length, breast width ≥45% of body length. Not acceptable: narrow build, absence of dewlap in obligatory breeds, black beak and legs in white European breeds.
