Crested Gecko Growth Chart and Development Stages

Crested geckos are dashing little lizards that can come in a variety of colors. These lizards live long lives and they are considered as one of the animals to keep as pets. Crested geckos have a moderate size, an adult is about 0-8 inches long which includes the tail i.e: up to 4 inches long. Smaller geckos are reached only 6-7 inches long.

Various Sizes

The size of crested geckos is also different according to their sex. Male crested geckos are a little bigger that weigh about 30 to 35 grams than female, which weighs about 25 grams in weight. If you want a bigger crested gecko then some breeds may help them to grow bigger but for a smaller crested gecko, the feeding is little.

With proper care, habitat, and maintenance your crested geckos may grow very quickly. They may reach up to 40-50 grams in weight, 8-10 inches in length once they got proper feeding as adults. Cresties are smaller species and they are lighter in weight, with proper care they may grow bigger.

Characteristics of crested geckos

  • The crested geckos, like other lizards, drop their tails if they feel threatened around their surroundings. However, the tail never grows back once falls off.
  • These lizards are nocturnal during the daytime. It means they are inactive and hiding during the day.
  • They are better known for their jumping abilities, so proper care should be taken when handling them to make sure that they don’t escape.
  • They keep their eye moistened by licking their eyeballs.
  • They require tall enclosures because they like to jump and climb.
  • For crested geckos, eating their shed is normal.

How long do crested geckos take to grow

It takes 14- 19 months for a baby to fully grow into an adult. Baby crested geckos weigh 3- 5 grams and measure 3-4 inches in length whereas it takes almost 12 months when they grow into an adult and weighs 35-50 grams and 9-16 inches in length. However, in different environments, the fluctuation in humidity and temperature shows different growth rates.

The ideal diet for most favorable growth among crested geckos

Crested geckos that eat gut-loaded insects reach adulthood faster than other crested geckos. 

Calcium and protein deficiencies in crested geckos may stop their growth. So make sure that their diet must be enriched with calcium and proteins:

Baby crested gecko diet:

Daily: Pangea crested gecko diet (A crested gecko powder food that is used mixing with water)

Every other day: insects, rotten fruits

Juvenile crested gecko diet:

Daily: Gut-loaded crickets, dobia roaches, or soldier fly larvae

2-3 times/ week: Calcium powder

Weekly: Reptile multivitamin if recommended by a veterinarian

Adult crested gecko diet:

Daily: Fruits like raspberries, oranges, Papaya, figs

2-3 times/week: Berries, grapes, watermelons, cherries, vegetables like okra, carrots, butternut squash, calcium+ vitamin D3, gut-loaded insects ( if the gecko is healthy weight)

Weekly: Fruits like pomegranate, bananas, plums, pumpkins, and cantaloupe

Biweekly: Reptile multivitamins if recommended by a veterinarian.

All ages:

Daily: Pangea gecko diet or high-quality food pre-mix like Repashy crested gecko.

 Supplemental: Apricots, peaches, bananas, pears, or squash foods can be given or can be mixed into pre-mix foods.

Factors that help in crested gecko growth faster

Few factors that help in crested gecko’s grow faster are mentioned below as:


The temperature of the crested gecko tank should be 75-78 degrees Fahrenheit with proper humidity. This suitable temperature may help in crested gecko growth faster.


According to experts, genetics plays an important role in the growth of crested geckos. Crested geckos from larger parents are expected to grow large in adulthood, while small parents are expected to produce small adult offspring.


Geckos’ growth is largely affected by dehydration. In dehydration, they eat less, weigh less, and grows slowly. Proper humidity in the enclosure helps to maintain an accurate level of moisture. Also, it may prevent dehydration and help your crested gecko to easily access clean water.

Incubation period:

Geckos who have an incubation period of 80-100 days tend to grow faster than those with shorter incubation periods. This is because the lower the hatching weight, the more difficult for a hatchling to eat or chew food. The larger the hatching weight., the easier for a hatchling to eat an adequate amount of food.

Reasons that your crested gecko is not growing

Several reasons may stop the growth of your crested gecko:

Nutritional deficiencies:

If your crested gecko is not receiving an adequate amount of calcium and proteins, then it may stunt its growth and may lead to health problems as well. Make sure that you are giving a well-balanced diet to your gecko to ensure faster growth and to save him from health problems.

Incorrect temperature:

Crested geckos are cold-blooded animals and they need environmental warmth for energy. If the temperature of the enclosure is too cold, then their body will not have much energy to eat and to perform all functions, so it may stop their body growth.

Incorrect humidity:

The humidity levels for crested geckos should be 50% but try to keep the humidity level inside the enclosure up to 70%. It may help your crested gecko hydrated and keep your gecko more comfortable. Dehydration may stunt the growth of crested geckos.

Tail dropping:

The tail of an adult crested gecko is usually 4-5 inches long. If your gecko becomes stressed and his tail drops off, then there will be a noticeable change in his weight and size.

Inadequate space in the enclosure:

If your crested gecko has a small enclosure then it may be difficult for him to climb, jump and hide. The too-small crested gecko enclosure may stunt the growth of crested geckos.


If you are concerned about the slow growth of your crested gecko, then it may be a sign of illness. If your crested gecko is not eating an insufficient amount and showing signs of weakness, then it may affect your crested gecko’s growth.

Bullying by other cage mates:

When your crested gecko is stressed by his cage mates and do not like their presence in room, he will stop eating. The behavior of your gecko may be aggressive and it greatly affects the growth and mental health of your gecko. Read more on crested gecko care.


When you made up your mind to keep crested geckos as your pet, so ask yourself if you have enough space and an appropriate size enclosure to keep them in your home. Remember that, crested geckos may live up to 10-20 years in captivity, so it requires a time commitment.

Crested geckos make great pets, but it is necessary to have full knowledge of their care before bringing the new family into a home. Pay attention to their diet and keep tracking their length after every 2 to 3 weeks. It may help you to keep a close eye on your gecko that whether he is growing healthy or not.
