How Big Do Bearded Dragons Get


Bearded dragons, also known as Pogona vitticeps, are one of the most popular pet reptiles around the world. Their friendly and docile nature, along with their unique appearance and manageable size, make them an ideal choice for both beginner and experienced reptile enthusiasts. One of the most frequently asked questions by potential bearded dragon owners is: "How big do bearded dragons get?" In this article, we will explore the various factors that influence the size of bearded dragons, their growth patterns, and some tips on how to ensure optimal growth and development for these amazing creatures.

Factors Affecting Bearded Dragon Size


Just like any other living organism, bearded dragons' size is influenced by their genetics. Each individual has a unique set of genes that determine their physical attributes, including size. If the parents of a bearded dragon were both large, it is likely that the offspring will also grow to be large. On the other hand, if the parents were small, the offspring will likely be small as well. However, it is important to remember that genetics is not the only determining factor when it comes to the size of bearded dragons, as other factors also come into play.


The diet of a bearded dragon plays a crucial role in its growth and overall size. In the wild, bearded dragons are omnivorous, meaning they eat both plant matter and small insects. A well-balanced diet consisting of a variety of vegetables, fruits, and protein sources such as crickets or mealworms is essential for their growth. Providing a diverse range of nutrients will ensure that they receive the necessary vitamins and minerals needed for healthy development. However, overfeeding or feeding an imbalanced diet can lead to obesity and other health issues, so it is important to monitor their food intake and adjust accordingly.

Environmental Factors

The environment in which a bearded dragon is kept also has a significant impact on its size. Temperature, humidity, and lighting are crucial factors that influence their growth and development. Bearded dragons require a warm basking area with a temperature around 95-100°F (35-38°C) to aid in digestion and metabolism. A UVB light source is also essential to provide them with the necessary UV rays for calcium metabolism and overall health. Inadequate temperature or lighting can hinder their growth, whereas optimal conditions will promote healthy growth and development.

The gender of a bearded dragon can also affect its size. Male bearded dragons tend to be larger than their female counterparts. This sexual dimorphism is a natural characteristic of the species, with males typically having larger heads, broader bodies, and longer tails. On average, adult male bearded dragons can reach a length of 18-24 inches (46-61 cm), while females usually measure around 16-20 inches (41-51 cm). However, it is worth noting that there can be variations within each gender, and individual growth rates may differ.

Growth Patterns of Bearded Dragons

Bearded dragons, like most reptiles, have a unique growth pattern. They are born as small hatchlings and gradually grow in size over the course of several months and years. Understanding their growth patterns can provide valuable insights into their development and help owners assess whether their bearded dragon is growing at a healthy rate.

Hatchling Stage

When bearded dragons hatch from their eggs, they are typically around 4-5 inches (10-13 cm) in length. At this stage, they are fragile and require a controlled and secure environment to ensure their safety. Hatchlings grow rapidly during their first year and can double or even triple their size within a few months if provided with proper care and nutrition.

Juvenile Stage

During the juvenile stage, which typically lasts from around 6 months to 1 year, bearded dragons experience significant growth. They continue to gain length and body mass, and their colors become more vibrant. A well-balanced diet, appropriate temperature, and the right amount of UVB light are crucial during this stage to support their growth and development. Juvenile bearded dragons are generally more active and curious, exploring their surroundings and displaying their unique behaviors.

Sub-Adult Stage

The sub-adult stage begins around 1-1.5 years of age, depending on the individual. At this stage, bearded dragons have reached a substantial size and are nearing their full adult size. They may still experience some growth during this stage, but it will be at a slower rate compared to the juvenile stage. It is important to continue providing them with a nutritious diet and proper environmental conditions to ensure they reach their full potential.

Adult Stage

The adult stage of a bearded dragon's life begins around 2 years of age. By this time, they have reached their full size and have matured both physically and sexually. Adult bearded dragons have a stable size and are generally less active compared to juveniles. However, it is important to note that even though they have reached their adult size, it is crucial to continue providing them with proper care and monitor their health to ensure they remain in optimal condition.

Tips for Optimal Growth

To ensure the optimal growth and development of your bearded dragon, there are several key factors to consider:

1. Proper Nutrition: Providing a well-balanced diet consisting of a variety of vegetables, fruits, and protein sources is essential for their growth. Consult with a reptile veterinarian or do thorough research to determine the appropriate diet for your bearded dragon based on its age and size.

2. UVB Lighting: Bearded dragons require access to UVB light to properly metabolize calcium, which is crucial for their bone health and overall well-being. Invest in a high-quality UVB light source and make sure it covers the entire habitat.

3. Temperature Control: Maintaining the appropriate temperature gradient in their enclosure is crucial for digestion and metabolism. Use a combination of heat lamps and temperature regulators to ensure the basking area is at the optimal temperature while providing a cooler area for them to retreat to.

4. Regular Veterinary Check-ups: Regular visits to a reptile veterinarian can help monitor your bearded dragon's growth, assess their overall health, and address any potential issues early on.


Bearded dragons can grow to varying sizes depending on several factors such as genetics, diet, environment, and gender. While genetics and gender play a significant role in determining their size, providing them with proper nutrition, UVB lighting, temperature control, and regular veterinary care are crucial for their optimal growth and development. Understanding their growth patterns and monitoring their size can help owners ensure the well-being of their bearded dragons and provide them with a fulfilling and healthy life. Remember, responsible ownership and care are key to raising happy and thriving bearded dragons.
