The plumage of the house sparrow is mostly different shades of grey and brown.

Younger birds are smaller, males are larger during the winter, and females are larger during the breeding season. The median mass on the European continent for both sexes is about 30 g (1.1 oz), and in more southerly subspecies is around 26 g (0.92 oz). Females usually are slightly smaller than males. In mass, the house sparrow ranges from 24 to 39.5 g (0.85 to 1.39 oz). Wingspan ranges from 19–25 centimetres (7.5–9.8 in). Its bill is stout and conical with a culmen length of 1.1–1.5 cm (0.43–0.59 in), strongly built as an adaptation for eating seeds.
