The Eurasian wren is a plump, sturdy bird with rounded wings and a short tail, which is usually held cocked up. It is 9 to 10 cm (3.5 to 3.9 in) in length and has a wingspan of 13–17 cm (5.1–6.7 in). It weighs around 10 g (0.35 oz). It is rufous brown above, greyer beneath, and indistinctly barred with darker brown and grey, even on the wings and tail. The bill is dark brown and the legs are pale brown, the feet having strong claws and a large hind toe. Young birds are less distinctly barred and have mottled underparts.
