Baby Bearded Dragon Size

Baby Bearded Dragons, also called hatchlings, aside from being beautiful, are really fast growers. They can often confuse you with their rapid growth if you are not familiar or a first-time owner. So, understanding their growth pattern and habits are really important. Baby Bearded Dragons can grow from 1 – 3 Inches a week, and within the first two months, they can grow up to 9 – 11 inches in length and 1.23 ounces. As this is a seriously rapidly growing stage, they require consistent feeding and can eat up to 50 crickets a day. So, always keep an eye on those hatchings and keep them feeding consistently to help them satisfy their monstrous appetite.

Juvenile Bearded Dragon Size

A Bearded Dragon in the age group of 4 to 12 months is considered Juvenile. And a Juvenile Lizard is known for its growth and behavior changes. Their growth rate starts consolidating in this stage, but it still shows significant gains. A Juvenile Bearded Dragon can grow up to 1 – 3 Inches in Size and 1.78 Ounces in weight each month. And at a six-month mark, you can analyze and judge if your beardie will grow up to be a humongous beast or will remain in those that are considered average. For example, a 15-inch beardie at 6 months is an indication that it will be a huge adult, and an 11 – 12 inch Juvenile will mean that it will be a slightly smaller adult. The Baby Beardie and early Juvenile stage dragons show astoundingly fast growth. Later on, they start slowing down, and most Bearded Dragons only grow 1 – 2 inches a month after six months. This is totally normal! They require a very high protein and nutrition intake at the early growing stages. That’s why it is important to feed them 80% of insects and 20% plants for 6 months. And once their growth starts slowing, you can balance that percentage to 50/50. Aside from growing, the Juvenile Bearded Dragons also start showing puberty signs at this stage. The jawline and flanks get harder, and the color becomes dull. And at adolescence, 10 – 12 months, they start displaying sexual behavior such as head bobbing, weaving, and unexplained digging.

Adult Bearded Dragon Size

Bearded Dragons reach sexual maturity between 8 to 18 months of age, and they are considered Adults once they achieve this feat. On average, it is observed that a male Bearded Dragon achieve adulthood by the age of 12 months and female bearded dragons are slightly ahead of them. A fully grown bearded dragon is 16 – 24 inches in size, and they reach this length mostly in 12 months. After that, they show very minimal growth in length and only increase their weight and width. It is a thumb rule that Bearded dragons usually stop growing once they achieve sexual maturity. In case they grow, it will be very minimal. A 24-month-old beardie will be the full-grown size, and they usually weigh between 14 – 17 ounces. A point to keep in mind for the new pet owners and lizard fans is in cold months, they often go to brumate, which may last from a few weeks to a few months. Beardies stop eating during the brumation period and normally rely on their stored body fat for survival.

Factors That Influence Bearded Dragon Growth

When it comes to a Bearded Dragon’s growth and size, age and species play a vital role. But, apart from that, other multiple factors may affect its growth and cannot be overshadowed. Here are some of these important factors that can greatly influence your Beardies Growth and should be taken care of in order to provide your beardie an optimal growth chance and environment.


Diet is compulsory for the beardie to grow up to its full potential. In each section of age, you need to consider its requirements and provide him with the best available nutrition so that he can utilize those to maximize its growth. Baby bearded dragons grow at a brisk pace, and that’s why they require a high amount of protein to consume. At the early stages 1 – 3 months, it is important to provide them 80% of insects to feed, and plants should be restricted to 20%. Once they grow bigger and get old, you can balance that percentage in order to help them with digestion and remain healthy. You can also feed your adult beardie some fruits to help bone growth and fight diseases, but it should not exceed 10% of their diet. Adult Beardies and especially pregnant female Bearded dragons will need calcium and a high amount of vitamin D3, so you can feed them supplements and nutrition-rich insects after getting them from a reputed breeder to avoid any mishaps.


When it comes to the discussion of size and growth, gender always plays a vital role. In bearded dragons, the rules are also the same male bearded dragons are slightly bigger and longer than the female bearded dragons. Still, it may differ in some cases, and female dragons can become larger than male ones, but it is not very common. Males are usually dominant, and they have a bigger head and tail base compared to females. However, female beardies do have a larger belly in contrast to their counterparts.

Male Bearded Dragons and Female Bearded Dragons Gender Identification

Gender Identification can be a core issue in most reptiles, but it’s pretty simple when it comes to bearded dragons. There are several ways to identify your beardies gender without taking it to the nearest vet for examination. You may have heard about the behavioral signs and how their actions can determine whether a beardie is a male or a female. It is a common misconception that male bearded dragons turn their beard black, and females always dig to keep their eggs hidden. But all of it isn’t true both the bearded dragon, a male or female, can turn their beard black, and both like digging and arm waving.

So, if all the methods are not perfectly accurate, what can be done to determine the gender at home?
Female Bearded Dragon
Looking at their hemi penal bulges or bumps is the most accurate and easy way for anyone to identify a beardies gender. Here’s how you can check it yourself and identify your bearded dragon’s gender. Pick them up, gently lift their tail from the backside, and use a flashlight to get a closer and clearer look. Males will have two bulges running parallel to the tail, and in the case of females, there will only be a single bump near the vent. The tail base of males will also be thicker than the females, and this method works 100% to identify the gender of bearded dragons correctly. However, if you are still not sure, pay a visit to your nearest vet for an x-ray to identify the bulges inside and get a crystal clear idea about the gender of your lizard.


Genetics always plays an important role when it comes to size, color, and certain traits. Everything is inherited from the parents, and as in most reptile pet cases, breeding is done in captivity, and you can choose certain traits as per your likings. In the case of bearded dragons, morph species are highly common, and if your beardie has a German Giant morph parent, it can grow up to 32 inches in size with a huge 35 ounces weight. But morphs always require special care, and it is hard to keep them healthy, so always get full insights before getting any of those as a pet.


Another highly important factor affecting a bearded dragon’s size is its environment. A small-sized tank or improper housing can lead to stunted growth, and you would never want that. You should always make sure that there is enough room and proper lighting is available. A Juvenile bearded dragon will need a 40 – 50 gallon enclosure and a fully grown adult should have a 120+ gallon tank to survive and live happily.

Bearded Dragon Weight

In Lizards and Reptiles, it is important always to keep an eye on their growth as health and growth go hand in hand for these species. Always keep measuring the length and weight of your lizard so that you have an idea if they are growing as per the normal standards or there is an anomaly. You may have to consider certain precautions if you find out that your beardie is either over or underweight.

If your bearded dragon is overweight

Suppose it seems that your bearded dragon looks bulky or has fat limbs, and its weight is growing rapidly. In that case, you should worry and always consider taking measures to ensure it remains healthy and fully fit. Lower the tank temperature it is living in as heat usually prompts them to eat and start giving them fewer insects to eat, this will lower their protein intake, and they will not get fatty. In some cases, you can also consider adding some exercises like walking in your lizard’s routine to keep it fit.

If your bearded dragon is underweight?

A lean beardie is a dead beardie! Suppose you see that your bearded dragon has saggy and wrinkly skin along with sinking fat pads at the back of the head. In that case, it is probably underweight, and worrying signs are there. In the early stages of growth, 1 – 3 months of having enough nutrition are mandatory; otherwise, they may go for early brumation, leading to stunted growth and illness. It becomes hard for them to recover from this stage; that’s why always keep an eye on their growth and diet in early life and keep a check if their ribs and spine are properly covered or protruding from the body. The growth chart above is the best way for you to keep track of your beardie’s weight and keep it healthy. The common cases at this stage for the loss of appetite and weight are temperature, food quality, and lack of nutrition. The cold temperature slows their metabolism, and they start eating less food; similarly, if you make them consume fewer proteins, it can hinder their growth process and cost them their health. Always check the temperature and give them enough supplements to gain weight and remain healthy.


Bearded dragons make a great pet for reptile lovers, first-time lizard fans, or pros alike due to their mellow, friendly, and irk nature. And How Big a Bearded Dragon can grow? It might seem to be a simple question, but it has a lot of hidden learning inside for both the pro reptilians and brand new lizard owners.

From providing them proper nutrition and a healthy diet to optimal tank size and flashy environment, it is key for you always to be a step ahead and let your bearded dragons grow up to their ultimate potential and live up to the name dragons.
