We investigated sexual size dimorphism in the tree frog, Hyla savignyi using 33 males and 22 females from the western and northwestern regions of Kermanshah Province, western Iran. Out of sixteen measured morphometric characters, four were significantly larger in females than in males. These characters were nostrileye length, brachium length, elbowlongest finger length and hind limb length.
