Want to learn more about Leopard geckos?

Maybe you’re trying to decide if they’re the right pet for you?

If so, you’ve probably wondered, “How big does a Leopard gecko get?”

Today, we’re going to answer that question and give you some extra info on these fun and colorful lizards. 

Adult female Leopard geckos are typically around 7″ to 8″ inches from snout to tail and weigh between 45 and 70 grams. Adult male Leopard geckos usually grow to be about 8″ to 10″ inches from snout to tail and weigh anywhere between 60 to 90 grams.

How Big Are Hatchling Leopard Geckos

Leopard gecko hatchlings are tiny, typically measuring about 2.5″ – 3″ inches long from snout to tail tip, and weighing around 3-5 grams.

Since they start so small, they need to receive special care and attention. 

Hatchling Leopard geckos should be housed in a small container measuring around 10″ inches long by 8″ inches wide by 6″ inches high.

This little space (compared to a large, full-sized tank) ensures they won’t get lost or have problems finding their food and water. 

Another thing to keep in mind if you have a small, hatchling Leopard gecko is only to use paper towels as a substrate.

Their small size puts them at a much higher risk of substrate impaction (experiencing intestinal blockage after accidentally consuming substrate particles).

Lining their container with paper towels helps prevent impaction problems.

Due to their small size, hatchling Leopard geckos require a very shallow water dish.

You may try using a plastic milk bottle top or something similar.

Just make sure whatever you use is shallow enough to prevent them from drowning. 

How Long Does it Take For a Leopard Gecko to Grow Full Size

Although hatchling Leopard geckos are tiny, they grow relatively quickly, reaching full size around the one year mark.

Although technically full-grown at one year of age, leopard geckos, like all reptiles, continue to grow their entire lives.

This is why they regularly shed their skin, even once they’ve reached adulthood. 

Are Male Leopard Geckos Bigger than Females

Male Leopard geckos are typically bigger than their female counterparts.

They will generally grow about 2″ – 4″ inches longer, have broader heads, thicker necks, a wider tail base, and bulkier bodies.

These size differences will most likely not be noticeable until they reach adulthood. 

Male Leopard geckos also have post-anal swellings and a V-shaped row of pre-anal pores.

While both sexes have cloacal spurs, the males are typically larger. 

How Big Does a Leopard Gecko Get

As we already learned, when Leopard Geckos hatch from their eggs, they are quite small, measuring about 2″ – 3″ inches in length and weighing only around 4 grams.

But Leopard geckos, the largest of the gecko species, grow quickly, reaching their adult size in about a year. 

Adult females are usually around 7″ to 8″ inches long from snout to tail tip and weigh between 45 to 70 grams.

Adult males are typically 8 to 10″ inches long from snout to tail tip and weigh anywhere between 60 to 90 grams. 

Why is my Leopard Gecko Not Growing

If your Leopard Gecko isn’t growing and appears much smaller than the average size and weight we mentioned above, there are four different possible reasons. 

Bullying

Yes, you read that right! Bullying is a common problem among Leopard geckos, especially between males.

If your Leopard gecko is housed in the same enclosure with other geckos, it may be getting bullied.

This means they may be fighting over food, water, or hiding spots, leaving the loser of the fight (usually the smallest or weakest of the bunch) without access to these necessities. 

The best solution to this problem is to house your geckos in separate enclosures.

Another possible solution is to only house males with females, never with other males. 

Nutritional Problems

Another reason why your Leopard gecko may not be growing correctly is because of a poor diet.

Your gecko may be eating regularly and getting enough quantity, but if the quality of its food doesn’t meet its nutritional needs, it will have a hard time growing and maintaining weight. 

Leopard geckos are insectivores and should be given a diet full of variety.

In other words, don’t make the mistake of only feeding it one or two different insects as this can lead to nutritional deficiencies.

Instead, give them a varied diet full of crickets, waxworms, silkworms, beetles, cockroaches, butter worms, and tomato hornworms.

Mealworms, waxworms, and superworms, though popular with Leopard geckos, should only be fed in moderation. 

It is also essential to gut load the feeder insects for a minimum of 24 hours before feeding them to your gecko.

Why? Since gut-loaded insects are well-fed themselves, they provide excellent nutritional value to your Leopard gecko.

If your gecko is young, you may consider coating the feeders with a calcium or Vitamin D3 plus Calcium supplement.

Tail Healing

Another common reason why Leopard geckos experience stunted growth is due to tail dropping.

If your Leo recently dropped its tail and since then you’ve noticed a decline or stunting in its growth or size, it may be because most of its nutrients are going towards repairing the tail. 

This is a natural process, and once the tail is healed, your gecko should continue to grow or regain the lost weight.

Just make sure you continue to offer it plenty of nutrient-rich food during this time. 

Health Issues

Finally, if your gecko looks thin and hasn’t been growing correctly, there may be a more significant health issue.

If you’ve made any necessary adjustments to your husbandry (separating geckos, offering a varied, nutrient-rich diet) and still your Leopard gecko is thin or not growing, it may be time to take it to the vet. 

Weight loss and stunted growth are sometimes an indication of more severe health problems going on, so it’s best to let an experienced reptile vet examine your Leo to ensure no other health problems are going on.
