Leopard geckos are around 7-9 inches (17.8-22.9 cm avg female)& (20-28 avg male) long, with large heads, big eyes with oval-shaped pupils, thin toes, and, unlike other reptiles, they have eyelids. They have thick tails that narrow to a point and, like their bodies and heads, are slightly flattened from top to bottom. Most of their scales are small and rough. Spaced rows of larger, bumpy scales give them a knobby, rough look, but they are actually soft when touched.
