The stretched penile lengths (spl) were measured by a single observer in a standing position. The average stretched penile length at birth is about 4 cm (1.6 in), and 90% of newborn boys will be between 2.4 and 5.5 cm (0.94 and 2.17 in). The penis was stretched as much as comfortably possible and length was measured up to the accuracy of 1 mm from pubic symphysis to the tip of the glans using a transparent, rigid ruler placed along the dorsal side of the penis.
