How big does a leopard gecko get?


When deciding on a pet, size matters.  How big your pet may get and how much space it will need factor into the decision (especially for pet owners in apartments or smaller living spaces.)  Leopard geckos are great pets for a number of reasons, and their size makes them an option for almost anyone looking for a small pet or reptile.

Adult leopard geckos may grow on average to 7-10 inches from nose to tail and weigh 50-80 grams.  Female leopard geckos average 7 to 8 inches in length at 50-70 grams, while males will be slightly larger at 8 to 10 inches long weighing 60-80 grams.  Hatchling leopard geckos average 3 to 4 inches in length and weigh only a few grams.

Giant and Super Giant Leopard Geckos

Giant and Super Giant leopard geckos are morphs genetically bred specifically to maximize their size. These leopard geckos may reach nearly 12 inches in length and weigh around 130-150 Grams. (The largest on record weighed in around 170 grams.)

The super giant gene is recessive, and these leopard gecko morphs may command a high price.

How fast do leopard geckos grow?

Leopard geckos have their fastest period of growth when they are young, where they are feeding every day and shedding often. Healthy leopard geckos typically reach their full adult size within their first year.

Does tanks size affect the growth of my leopard gecko?

Tank size does not have a big impact on the size of your leopard gecko, though it may greatly affect its quality of life.

Keeping a pet in an enclosure too small will limit its ability to move around, get exercise, find places to hide or sleep, hunt for food, or regulate its body temperature.

A juvenile leopard gecko will do fine in a 10 gallon tank. Once they’re full size, consider a 20 gallon or larger enclosure. For leopard geckos, floor space is better than height since they are not avid climbers.

Factors that affect the size of a leopard gecko

Leopard Gecko Genetics

The genes inherited from a leopard gecko’s parents play a major role in its size as well as other factors such its pattern and color. You can read more in our post about leopard gecko genetics.

Sex and Leopard Gecko Size

Males leopard geckos are typically larger than females, as outlined in the chart above.


Proper Feeding and Nutrition

Having access to a a supply of quality food not only affects the general health of your leopard gecko, but allows it to grow to a natural size.

Malnourished geckos will tend to be smaller and underweight. Improper diet, not gut loading feeder insects, or being bullied by a more dominant gecko may all contribute to not getting enough food.

Wrap Up: How big do leopard geckos get?

Leopard geckos are fairly small reptiles, which make them a great option as a pet. They can range from 7-10 inches long and around 70 grams on average. Special super giant morphs may be a few inches longer and nearly twice the weight.
