Full Size Bearded Dragon

One of the friendliest, most engaging reptiles you can keep in captivity is the bearded dragon. Because of their peculiarities, cool appearance, and curiosity, owners are drawn to them. When you know just how to keep up their cage and supply a wholesome meal, these lizards are pretty simple to care for.

If you’re a new beardie owner, you’re undoubtedly reviewing all the information you can find. The ability to grow is crucial for bearded dragons. Your young dragon will grow big and strong—just as they should—with the right environmental conditions and a healthy food.

Facts About Bearded Dragons

Native to Australia’s hot environment, bearded dragons are desert lizards. In the 1990s, bearded dragon domestication really took off in the United States.

However, the gregarious aspect of these amazing desert inhabitants has won over many reptile enthusiasts.

These cute creatures with rough skin have the following interesting facts:

They can move at speeds of up to 9 mph. Even while humans can run considerably more quickly, once your tiny beardie picks up the pace, it might be challenging to catch them.

They adore swimming utterly. Your bearded dragon will enjoy taking a bath. They are adept swimmers that can move through the water quickly and precisely using their body composition and motions.

Their sex can be changed. Even though it’s uncommon, it may happen—typically when they’re still in the egg.

To communicate, they bob their heads and wave. You may have seen videos of cuddly bears. Although head bobbing is a form of communication, it may also be an aggressive gesture.

Bearded dragons come in several varieties. Breeders have sought to diversify the species’ breeds.

Trees are climbable by them. Beardies are exceptional tree climbers due to their general structure and sticky claws. They may thus scale many different surfaces within your house.

They are laying hens. Bearded dragons deposit eggs to reproduce since they are cold-blooded animals.

They like being alone. Although you might be able to maintain female bearded dragons together, most of them prefer to live alone.

If you mix males, they could even engage in a battle to the death.

They release a little poison. Due to the fact that humans are not affected by the poison beardies release, this fact is not as well recognized. Beardies do, however, possess a minor poison to kill their victim.

Their tails cannot grow back. Bearded dragons, unlike certain other lizards, are unable to regrow their severed tails to their original shape.

How Big Do Bearded Dragons Get?

When a bearded dragon reaches sexual maturity, it reaches its maximum size. Every lizard develops sexually at a different age, but most do so between the ages of 8 and 18.

Your Beardie’s growth will dramatically slow down after a year. A healthy adult at this age will have a full belly and a robust tail base.

If it exceeds 24 inches in height, it most likely belongs to the rare German Giant morph. German giants may reach a maximum size of 32 inches and 1,000 kilos.

If a Beardie is under 16 inches in height or weighs less than 300 grams after a year, they are deemed unhealthy.

If your pet is more than 12 months old and still hasn’t grown to the minimal size mentioned above, it’s possible that their growth has been impeded. Numerous reasons can lead to stunted growth, which can have an impact on a child’s physical or intellectual development.

Baby Bearded Dragon Size

When they hatch, baby bearded dragons are only four grams and three inches long.

They will grow to be between 8 and 11 inches long in three months due to their incredibly rapid development rate.

The usual lifespan of a wild bearded dragon is only five years, therefore this rapid development is crucial. However, pet animals can live up to 15 years when maintained for correctly. Wild species have a higher success rate in reproducing because they reach sexual maturity and full size sooner.

A newborn should develop 1 to 2″ and gain 10 to 50 grams per month.

Do not become alarmed if it does not continue to increase at this precise rate.

Depending on their genetic makeup and tank configuration, individuals frequently develop at somewhat different speeds. Additionally, females are typically lighter and shorter than males and tend to grow at a slower rate.

If you observe that your lizard is growing much more slowly than this predicted rate, it may be a symptom of an underlying health issue or an inadequate tank design.

It’s crucial to monitor your baby’s growth rate.

When a newborn beardie is four months old, it will have entered the juvenile stage.

They most likely have smooth skin, little spines, and quite pronounced black stripes across their bodies as infants. During the juvenile period, the texture and color of their skin should start to harden.

Bearded Dragon Growth Rate

The growth phase of young bearded dragons is significantly fast. Their size will expand swiftly from three to eleven inches within their first three months of existence.

They should gain between 10 and 50 grams per month and grow two inches each month.

They will grow a little more slowly after three months of age.

Juveniles gain 50 grams per month and grow 1 to 1.5 inches each month.

During their fast development period they shed once or twice a month. After a year, the rate of their size growth stops growing, and they only shed once or twice a year.

Your bearded dragon will weigh about 350 grams after a year and add weight steadily over the next 12 months.

Juvenile Bearded Dragon Size

Your lizard will be developing more quickly than ever as a youngster. A young bearded dragon should gain between 60 and 80 grams and grow 1 to 3 inches per month.

Their size at six months of age is a good indication of how large they will be when fully grown. For instance, a bearded dragon will grow into a very large adult if it is 15″ or longer at six months old. A person who is 11 inches tall will also be on the smaller side as an adult.

You should also notice a slowdown in their growth rate around the halfway point. About 50–70 grams and 1–2″ should be lost each month. This is quite typical.

As your juvenile approaches full size, its growth rate is likely to continue to decline.

Your lizard should be fed on around 80% insects and 20% plant matter while it is a newborn or an early juvenile. This will ensure that they receive enough protein to promote healthy growth. This diet should be lowered to 50% insects and 50% plant material at roughly six to eight months of age.

Your bearded dragon will instinctively desire to consume new plants and veggies when their pace of development slows down.

During late adolescence, juveniles will grow to a length of around 12″. (10-12 months). They will be approaching sexual development and adulthood at this age. They may even exhibit sexual gestures like head bobbing, arm waving, and digging.

Although it is uncommon, several owners have stated that their bearded dragon was fully grown at eight months old.

Is this the period when owners start to inquire about the bearded dragon’s size?

A juvenile can be between 16 and 24 inches in length, depending on the individual. Though they are frequently lighter and shorter by nature, most girls develop slightly more quickly than men.

As a youngster, you could observe your lizard progressively shedding some of its darker stripes and altering its color. It may also start to grow larger and harden the lumps and spines on its jaws and sides.

How Big Do Bearded Dragons Get When Fully Grown?

You must first determine how large your bearded dragon will be when it is completely grown in order to provide it with the correct care. This is crucial since it will enable you to choose the ideal cage and establish a feeding strategy.

For the first three months of their lives, these reptiles develop swiftly. After then, throughout the remainder of the year, bearded dragons grow an additional 1 to 2 inches every month. Later, during their whole second year of life, these reptiles can still grow an additional 1 to 2 inches.

Bearded dragons may reach a maximum length of 12 to 24 inches once they have finished growing (this measurement includes the tail). No matter how big your home is, they are an excellent pet due to their easily managed size.

Expert Advice: A bearded dragon is often regarded as fully grown if it is 11 to 12 months old. Some people, however, may not even be considered adults for another 18 months.

As you can undoubtedly imagine, it’s difficult to forecast with absolute certainty how big your bearded dragon will grow.

This is due to the fact that a variety of elements pertaining to a bearded dragon’s growth processes must be taken into account. Some will achieve their maximum size by the time they are 8 to 10 months old, while others won’t until later in their second year of life.

How Fast Do Bearded Dragons Grow?

As young animals, bearded dragons may grow up to 11 inches long and up to 1.23 ounces in just two to three months. After that, the growth rate decreases to 1-2 inches, and throughout their first year as juveniles, they acquire 1.76 ounces every month. In their second year as adults, they may add an additional inch or two to their height.

How long does a bearded dragon take to reach its maximum size?
Bearded dragons mature sexually and develop to full size between 8 to 18 months. Bearded dragons in full size may grow to be between 22 and 24 inches long.

Bearded dragons cease developing at what age?
While most bearded dragons cease growing at the age of 11 to 12 months, some can continue to grow up to 18 months or even two years old! Senior bearded dragons may still grow, but more often than not, they only put on weight rather than lengthening.

Factors That Influence A Bearded Dragon’s Size

When you first hold your little dragon, you can’t not but make an educated guess as to how much bigger it will eventually get. You would be correct to picture a size increase of two, three, or four times.

Their growth will likely be rather dramatic.

During the first year of life, babies and adolescents develop quite quickly, but what variables affect how quickly they grow?

Genetics. Your dragon can grow to a maximum size that is mostly determined by genetics. These characteristics are inherited from the size of their parents.

Gender. Their size is also influenced by gender. The sexual dimorphism of bearded dragons is more modest than that of other pet lizards. Femoral pores, lumps on the ventral portion of the tail, and morphological differences between males and females may all be detected.

Females commonly range in length from 16 to 19 inches. In terms of length and head size, they are often on the lesser end of the spectrum.

Diet. A bearded dragon has to be fed a balanced diet in order to develop and grow appropriately. Low-nutrient meals, such iceberg lettuce, should be avoided since they might hinder an animal’s growth.

Additionally, avoid providing insects heavy in fat with an unbalanced diet of nutrients (e.g. grubs).

Reasons Why They Might Not Grow Properly

Healthy growth of bearded dragons depends on a balanced diet. A bearded dragon’s first year should be spent on a high-quality, protein-rich diet.

A diet consisting of 80% insects and 20% plant materials is recommended for infants between the ages of 0 and 6 months. Small meals should be given to them several times each day.

You should start progressively reducing the amount of dietary protein to 50% at six months of age. At twelve months of age, a diet consisting of 80% fruits and vegetables and 20% protein is recommended.

During this time of rapid growth, inadequate protein and calcium intake can result in health problems like stunted growth, poor bone and muscle development, and metabolic bone disease.

Low-nutrient meals like iceberg lettuce should be avoided at all stages of growth. They nearly entirely lack the vitamins and minerals required for proper development.

Poor Tank Configuration
A bearded dragon needs to be able to roam around its tank without restriction. Strength and good bone formation are promoted by exercise.

Inactivity, stress, and obesity can all be caused by improper tank setup. Bearded dragon obesity may cause slowed development or weight loss.

The Max Size Of Each Common Species

There are several bearded dragon species, and each species has a unique maximum size and pace of growth.

To assist owners in predicting how large their bearded dragon will grow, the differences in size and growth for each of the popular species are discussed here.

The most frequent and well-known bearded dragon is Pogona Vitticeps, which is located in the center. Natural habitats for these bigger reptiles include woods, deserts, and dry shrub regions.

The majority of Pogona Vitticeps owners indicate that this species is normally docile and enjoys climbing. As a general rule, these lizards stay awake during the daytime.

When fully grown, this bearded dragon may reach a length of 24 inches.

One of the largest bearded dragon species, Pogona Barbata, may grow to a length of 24 inches.

Coastal Bearded Dragon or Eastern Bearded Dragon are other names for Pogona barbata. Bearded dragon owners-to-be should be informed that this species is renowned for being aggressive when around other people. Additionally, owners may anticipate that these lizards will be active during the day.

The Pogona barbata enjoys climbing and sauntering around, just like the majority of other species. These lizards can be found in dry, forested places in the wild.

These Pogona Minor Mitchelli, sometimes known as Mitchelli Bearded Dragons, may reach lengths of up to 18 inches. This species is often relatively scarce. Both semi-tropical wooded areas and desert areas are likely to harbor these lizards.

Pogona Minor – The Pogona minor, often known as a dwarf bearded dragon, can reach a maximum length of 14 to 18 inches. This species of lizard, which is also uncommon, prefers rocky terrain as well as forested places that are sheltered by trees.

Another uncommon species, the Pogona Nullabor or Nullabor Bearded Dragon, may reach a maximum length of 14 inches when completely grown. These medium-sized lizards live in dry, primarily flat, brush habitats.

Pogona Minor Minima, also known as the Western Bearded Dragon, is another name for this species.

These rare lizards, which only reach a maximum length of 12 inches, prefer dry, forested habitats.

These smaller dragons are known as Pogona Henrylasoni, or Lawsons Bearded Dragons. Owners may anticipate that these lizards will remain tiny, only growing to a maximum length of 12 inches.

These reptiles enjoy dry, rocky areas where they may spend their days contentedly climbing in their natural habitats.

Drysdale River Bearded Dragon is the popular name for the Pogona microlepidota species. This lizard is relatively uncommon and usually inhabits coastal or wooded environments.

The tiniest beardie, only reaching a height of 4 to 6 inches during its lives!

The Pogona vitticeps is the bearded dragon species that is kept the most frequently, as was previously noted. At the age of one year, these well-known bearded dragons should reach 15 to 18 inches long.

Some could be a little bit smaller, while others might gain a few more inches over the second year. By the time they are between 12 and 18 months old, these beardies are typically regarded as adults.


Monitoring your beardie’s development will only comfort you that everything is going according to plan. Being uncertain of your actions might be nerve-wracking, especially if you’re a novice owner.

Keep a feeding plan so you can be sure they are receiving the proper amount of food for their age. Additionally, UV light is crucial since they actually require the vitamin D.
