Knowing what to expect as your Bearded Dragon matures will help you provide the optimal conditions for them to thrive. In this article, we’ll delve into the different stages of growth, explore the factors influencing their size, and offer tips on how to support their healthy development, ensuring your Bearded Dragon reaches its full potential.

4 Growth Stages of Bearded Dragons

1. Hatchling Stage

Bearded Dragons begin their life’s journey as tiny hatchlings, measuring just about 3 to 4 inches in length. This initial stage is marked by rapid growth, with a significant increase in size occurring within the first few weeks to months of life. Hatchlings grow at a rate of approximately 1 to 2 inches per month, which is astonishing when you consider their small starting size. During this stage, proper nutrition and optimal environmental conditions are vital, as they lay the foundation for the dragon’s future health and development.

2. Juvenile Stage

As Bearded Dragons transition from the hatchling to the juvenile stage, usually around 2 to 3 months of age, they typically reach a length of 6 to 10 inches. The juvenile stage is characterized by a more moderate growth rate compared to hatchlings but remains a crucial period for development. During this phase, dragons are highly active and require a diet rich in protein to support their growing bodies. They can grow approximately 1 to 1.5 inches per month during this stage. Ensuring that their habitat is appropriately sized and that they have access to UVB lighting and proper temperatures will help them thrive during this important growth period.

3. Sub-Adult Stage

The sub-adult stage, generally occurring between 6 to 12 months of age, is when Bearded Dragons begin to approach their adult size. By this stage, most dragons will measure between 10 to 18 inches in length. Growth slows down considerably during the sub-adult stage, but dragons are still developing both physically and behaviorally. It’s important to continue providing a balanced diet and maintain proper husbandry practices to ensure they reach their full potential. The sub-adult stage is also when gender differences in size may become more apparent, with males typically growing slightly larger than females.

4. Adult Stage

When a Bearded Dragon reaches adulthood, usually between 12 to 18 months of age, it will have achieved its full size. Adult Bearded Dragons typically measure between 16 to 24 inches in length, including their tail, with some larger species and morphs reaching up to 26 inches. Males are generally larger and bulkier than females, with more pronounced head structures and broader bodies. Once they reach this stage, growth in length largely stops, but they may continue to fill out and gain weight until they are about 2 years old. Maintaining a healthy weight through proper diet and exercise is essential to prevent obesity and related health issues in adult dragons.

What Are the Factors Influencing The Size Bearded Dragons?

The size of Bearded Dragons is influenced by several key factors, which determine how large they will grow and how healthy they will be throughout their lives. Here’s a breakdown of the main factors:

1. Species and Morph Variations

The specific species of Bearded Dragon plays a significant role in determining its size. The most common species kept as pets, the Central Bearded Dragon (Pogona vitticeps), typically grows between 16 to 24 inches in length. Other species, such as Rankin’s Dragon (Pogona henrylawsoni), are smaller, usually reaching about 10 to 12 inches.

Within each species, there are various morphs—genetic variations that can affect size. Some morphs may be selectively bred for larger or smaller sizes, and the differences can be noticeable even within the same species.

2. Diet and Nutrition

Proper nutrition is crucial for the growth and size of Bearded Dragons. During their early stages, a diet rich in protein, primarily from insects, supports rapid growth. As they mature, their diet should shift to include more vegetables and greens to maintain their health and prevent obesity.

Calcium and vitamin D3 supplements are important, especially in young dragons, to support bone development and prevent metabolic bone disease. The lack of proper supplementation can stunt growth and lead to serious health issues.

3. Habitat and Environment

The size of the enclosure impacts the overall well-being of a Bearded Dragon. A tank that is too small can cause stress and limit the dragon’s ability to move and exercise, which can indirectly affect its growth. An adult Bearded Dragon requires a tank of at least 40 to 75 gallons to thrive.

Adequate UVB lighting is essential for calcium absorption and bone health. The basking spot in the enclosure should be kept at around 95 to 105°F, with a cooler area of 75 to 85°F to mimic their natural environment. Improper lighting and temperatures can lead to health issues, including stunted growth.

4. Genetics

Genetics plays a fundamental role in determining the potential size of a Bearded Dragon. Dragons bred from larger parents are more likely to grow larger, while those from smaller lineage may stay on the smaller side. Breeders often select for size and other traits when pairing dragons, influencing the growth potential of their offspring.

5.  Sex

Gender Differences: Typically, male Bearded Dragons are larger than females. Males usually have broader heads and bodies, as well as longer tails. These differences become more pronounced as the dragons reach adulthood.

Common Size Ranges for Bearded Dragons

The Central Bearded Dragon (Pogona vitticeps) is the most commonly kept species and is known for its relatively large size. On average, an adult Central Bearded Dragon measures between 16 to 24 inches in length, with some reaching up to 26 inches in exceptional cases. Males are typically larger than females, often by a few inches. Their robust size and relatively easy care make them a favorite among reptile enthusiasts.

Other Common Species

While the Central Bearded Dragon is the most popular, there are several other species of Bearded Dragons that are kept as pets, each with its own size range:

  1. Rankin’s Dragon (Pogona henrylawsoni): This species is much smaller than the Central Bearded Dragon, typically reaching only 10 to 12 inches in length. They are known for their more docile nature and are a good option for those who prefer a smaller dragon.
  2. Eastern Bearded Dragon (Pogona barbata): Slightly larger than the Central Bearded Dragon, the Eastern Bearded Dragon can grow up to 24 inches, though they are less commonly kept as pets.

Each species has unique characteristics, but their size is a primary consideration for prospective owners.

Tips for Supporting Healthy Growth of Bearded Dragon

Here are six tips for supporting the healthy growth of Bearded Dragons:

Provide a Balanced Diet

Ensure your Bearded Dragon receives a diet rich in proteins (like insects) during early growth stages, gradually introducing more greens and vegetables as they mature.

Maintain Proper Lighting

Use UVB lighting to aid calcium absorption and prevent metabolic bone disease, crucial for healthy growth and bone development.

Ensure Optimal Temperatures

Keep the basking spot at 95-105°F and provide a cooler area of 75-85°F to mimic natural conditions and promote proper digestion and growth.

Regularly Monitor Growth

Track your Bearded Dragon’s weight and length to detect any growth issues early, and adjust their diet and habitat as needed.

Provide Adequate Space

Use a spacious enclosure (at least 40-75 gallons for adults) to allow your dragon to move freely, promoting physical activity and growth.

Minimize Stress

Create a stress-free environment by handling your dragon gently, maintaining a clean habitat, and avoiding sudden changes in their surroundings.

Common Myths About Bearded Dragon Size

There are several myths surrounding the size of Bearded Dragons, some of which can lead to misconceptions about their care:

Myth 1: Bearded Dragons Will Only Grow as Large as Their Tank Allows.

This is a common myth that is entirely false. While the size of the tank can impact the dragon’s comfort and stress levels, it does not determine their ultimate size. Genetics, diet, and overall health are the primary factors that influence growth.

Myth 2: All Bearded Dragons Reach the Same Size.

Not all Bearded Dragons will grow to the same size. Factors such as species, morph, diet, and genetics all play a role in determining the final size of a dragon. Some will naturally be larger or smaller than others.

Myth 3: Overfeeding Leads to Larger Dragons.

While providing a nutritious diet is important, overfeeding can lead to obesity, not increased length or height. Obesity can cause numerous health issues, including a shorter lifespan and reduced mobility. 

The Bottom Line

Understanding how big Bearded Dragons get is essential for providing the right care throughout their lives. From their rapid growth as hatchlings to their more measured development into adulthood, each stage of a Bearded Dragon’s life requires careful attention to diet, habitat, and health. By following the tips outlined in this article, you can ensure that your Bearded Dragon grows to its full potential, living a healthy and fulfilling life as a beloved pet.
