How Big Are Crested Geckos?

Crested geckos are small reptiles native to New Caledonia, an archipelago located east of Australia in the South Pacific. They have become popular pets due to their friendly nature and need for minimal care.

Average Size

On average, crested geckos can grow up to 8-10 inches in length, with males typically reaching the larger end of this range. However, the size of the gecko can change depending on the age, sex, and breeding.


An adult crested gecko typically weighs around 40-50 grams, or 1.5-2 ounces. Juveniles, on the other hand, usually weigh anywhere between 15-20 grams.

Factors That Affect Size and Weight

There are several factors that can affect the size and weight of crested geckos, including:

  • Age: Younger geckos tend to be smaller and weigh less than older geckos.
  • Sex: Males are typically larger and heavier than females.
  • Breeding: Breeding can affect the size and weight of crested geckos by increasing hormones and other bodily functions related to growth.

It’s important to note that despite their small size, crested geckos can become overweight and obese if they are overfed. To ensure your gecko is healthy, keep a watchful eye on their diet and activity level.

Overall, crested geckos can range in size and weight depending on their age, sex, and breeding. But on average, they are 8-10 inches long and 40-50 grams in weight.
