How Long Do Bearded Dragons Grow


Bearded dragons, scientifically known as Pogona, are fascinating reptiles that have become popular pets worldwide. These unique creatures are native to the arid regions of Australia and are known for their distinctive appearance, including spiky scales and a beard-like projection under their chin. As with any pet, it's important for owners to understand the growth and development of their bearded dragon. In this article, we will explore the factors that influence the growth of bearded dragons and answer the common question: "How long do bearded dragons grow?"

Factors Affecting Bearded Dragon Growth


Genetics play a significant role in determining the size and growth rate of bearded dragons. Just like humans, bearded dragons inherit certain traits from their parents. These traits can include size, coloration, and growth potential. If a bearded dragon comes from parents who were larger and healthier, it's likely that the offspring will also grow to be a substantial size.


Proper nutrition is crucial for the healthy growth of bearded dragons. Young bearded dragons, in particular, have higher growth rates and require a diet rich in protein, calcium, and vitamins. Inadequate nutrition can lead to stunted growth and various health problems. It's important for owners to provide a balanced diet that includes a variety of live insects, vegetables, and fruits to ensure optimal growth.

Environmental Factors

The environment in which a bearded dragon is raised can also have an impact on its growth. Factors such as temperature, humidity, lighting, and cage size can influence the rate at which a bearded dragon grows. Bearded dragons require proper temperature gradients within their enclosure to regulate their body temperature and metabolism. Additionally, exposure to natural sunlight or the use of UVB lighting is essential for vitamin D production, which is important for calcium absorption and overall growth.

Health and Care

The overall health and care provided to a bearded dragon greatly influence its growth and development. Regular veterinary check-ups, proper hygiene, and appropriate handling techniques are essential for maintaining the health and well-being of these reptiles. Any underlying health issues, such as metabolic bone disease or parasites, can hinder growth and should be promptly addressed by a qualified veterinarian.

Growth Stages of Bearded Dragons

Hatchling Stage

When bearded dragons hatch from their eggs, they are typically around 3 to 4 inches in length and weigh just a few grams. At this stage, they are extremely fragile and require extra care and attention. It's essential to provide them with a suitable enclosure, proper heating, and a diet consisting of small insects such as pinhead crickets and small mealworms. Hatchlings grow rapidly during their first few months of life, and their size can double or even triple by the time they reach the juvenile stage.

Juvenile Stage

During the juvenile stage, which typically lasts up to one year, bearded dragons experience significant growth. They go through several shedding cycles, during which they shed their old skin to accommodate their expanding bodies. At this stage, their diet should consist of a variety of small insects, such as crickets and roaches, as well as a mix of leafy greens and vegetables. Juvenile bearded dragons can reach an average length of 10 to 12 inches and weigh around 100 to 150 grams.

Sub-Adult Stage

The sub-adult stage is a transitional phase between juveniles and adults. At this stage, bearded dragons undergo further growth and sexual maturation. The length and weight of sub-adult bearded dragons can vary greatly depending on genetic factors and the care provided. On average, sub-adult bearded dragons reach a length of 16 to 20 inches and weigh between 200 to 400 grams. Their diet should consist of a mixture of insects, vegetables, and fruits to support their growth and overall health.

Adult Stage

Bearded dragons typically reach their adult size by the age of 18 months to two years. The length and weight of adult bearded dragons can vary depending on several factors, including genetics and sex. Male bearded dragons are generally larger than females and can reach lengths of 20 to 24 inches, while females tend to be slightly smaller, averaging around 18 to 22 inches. The weight of adult bearded dragons can range from 300 to 600 grams or more, again depending on various factors.


In conclusion, the growth of bearded dragons is influenced by a combination of genetic factors, nutrition, environmental conditions, and overall care. By understanding the various stages of growth and providing the necessary resources and attention, owners can ensure the healthy development of their bearded dragons. From hatchlings to adults, these captivating reptiles captivate us with their unique appearance and captivating personalities. So, if you are considering getting a bearded dragon as a pet, remember to be prepared for their growth journey and provide them with the care they need to thrive.
