How big do crested geckos get?
Adult crested geckos usually grow to about 8 inches long from head to tail, though some reach up to 9 or 10 inches. Their body without the tail is roughly 4 to 5 inches, about the size of an adult’s hand.
Over the past two years, I’ve gone to several reptile expos, including the Tinley Park Reptile Expo three times, and the Goshen Reptile Expo. Crested geckos are a very common reptile to see at these events, and vendors who bring them will often get one out to show people or have them sitting on a perch just hanging out. They’re so chill that they don’t try to take off or escape.
In all of these instances, the geckos I’ve seen are usually palm-sized. When they still have their tail, it can extend past an average man’s hand, but their head and body fit comfortably within an adult’s palm. The gecko in the first image was a young one, probably a juvenile, seen at the Tinley Park Reptile Expo.
