It is 25 to 29 cm (9.8 to 11 in) long. Males weigh 53 to 72 g (1.9 to 2.5 oz) and females 54 to 83 g (1.9 to 2.9 oz). The sexes have the same plumage.

Voice: The northern barred woodcreeper mostly sings at dawn and dusk but also intermittently during the day. The song of the "western" three subspecies is a series of loud whistles that rise at the end. It is variously put in words as "téw-wee, téw-wee, téw-weea", a "slightly nasal pwee-PWEE-PWEE-PWEE-peeeurr", "a penetrating doh-wee, doh-wee, doh-wee, do-wee", and "oowít, oowít, oowít, OOWIT, OOWIT!".
