The spectacled owl can range from 41 to 52.3 cm (16.1 to 20.6 in) in length. Mass in males can range from 453 to 1,075 g (1.00 to 2.37 lb), whereas females can weigh from 680 to 1,250 g (1.50 to 2.76 lb). 10 males from the nominate subspecies (P. p. perspicillata) were found to average 767 g (1.69 lb) while 8 females averaged 908 g (2.00 lb).
