How To Tell The Age Of A Bearded Dragon

Bearded dragons are fascinating reptiles that have become popular pets in recent years. Whether you are a new owner or a seasoned reptile enthusiast, knowing the age of your bearded dragon is essential for providing proper care and understanding its behavior. In this article, we will explore different methods and indicators that can help you determine the age of your bearded dragon.

1. The Size and Growth Rate

Understanding the growth rate of bearded dragons can provide valuable insights into their age. Like most reptiles, bearded dragons grow rapidly during their early years, and their growth starts to slow down as they reach maturity.

1.1 Hatchling Stage

During the first few months of their lives, bearded dragons are considered hatchlings. They are typically around 4-6 inches long and have a much more slender appearance compared to adult bearded dragons. Hatchlings grow quickly, and within their first year, they can reach a length of 12-14 inches.

1.2 Juvenile Stage

After the hatchling stage, bearded dragons enter the juvenile stage. This stage usually lasts until they are around 18 months old. Juvenile bearded dragons grow at a slightly slower rate compared to hatchlings but still experience significant growth. During this stage, they undergo a noticeable increase in body size, and their tail becomes thicker and longer.

1.3 Sub-Adult and Adult Stage

Once bearded dragons reach around 18 months old, they are considered sub-adults. At this stage, their growth rate significantly slows down, and they start to fill out their body structure. It is common for sub-adults to display some sexual dimorphism, with males having larger heads and femoral pores compared to females. By the time they reach 2-3 years old, bearded dragons are considered adults, and their growth rate essentially stops.

2. The Development of Physical Characteristics

There are specific physical characteristics that can give you an idea of your bearded dragon's age. These characteristics, such as the color of their scales and the presence of certain markings, gradually change as the bearded dragon matures.

2.1 Coloration

Bearded dragons undergo color changes as they age. Younger bearded dragons tend to have brighter and more vibrant colors, while older individuals may develop a more muted hue. The presence of bold patterns and markings is also more prominent in younger dragons but tends to fade as they age. However, it is important to note that coloration can also be influenced by factors such as genetics, health, and environmental conditions.

2.2 Hemipenal Bulges

In male bearded dragons, the development of hemipenal bulges can be a good indicator of age. Hemipenal bulges are small swellings located just above the vent on either side of the tail base. They become more prominent as the bearded dragon matures. Younger males may have small or barely visible bulges, while older males have larger and more defined ones.

2.3 Femoral Pores

Femoral pores are tiny openings on the underside of a bearded dragon's hind legs. These pores secrete a waxy substance called preen gland secretion. While both males and females have femoral pores, they tend to be more prominent in males. The size and visibility of femoral pores increase with age, making them useful for estimating a bearded dragon's maturity.

2.4 Head Shape

The shape of a bearded dragon's head can also provide valuable clues about its age. Younger dragons typically have smaller heads in proportion to their bodies, while older dragons have larger and more well-developed heads. Additionally, males often have larger heads compared to females, especially once they reach sexual maturity.

3. Shedding Patterns and Frequency

Bearded dragons shed their skin periodically as they grow. Tracking their shedding patterns and frequency can offer insights into their age and overall health.

3.1 Hatchlings and Juveniles

Younger bearded dragons typically shed more frequently compared to adults. Hatchlings and juveniles shed their skin every few weeks as they experience rapid growth. The shed skin may appear more transparent or whitish in color and often comes off in small, fragmented pieces.

3.2 Sub-Adults and Adults

As bearded dragons mature, their shedding patterns change. Sub-adults shed less frequently, with shedding occurring approximately every 4-6 weeks. The shed skin becomes more intact and can often be peeled off in larger pieces. Adult bearded dragons shed even less frequently, with shedding occurring every few months.

4. Teeth and Jaw Structure

Examining a bearded dragon's teeth and jaw structure can provide clues about its age. Like humans, bearded dragons have teeth that continuously grow throughout their lives. The appearance and condition of their teeth can indicate their age and overall health.

4.1 Hatchlings and Juveniles

Younger bearded dragons have smaller and sharper teeth compared to adults. Their teeth are more uniformly white and exhibit less wear. As they grow, their teeth gradually become larger and may start to show signs of use.

4.2 Sub-Adults and Adults

Sub-adult and adult bearded dragons have larger teeth with more visible wear and tear. Their teeth may appear slightly yellowish or discolored due to the accumulation of plaque. However, it is important to note that dental health can vary depending on diet and oral hygiene practices.


Determining the age of a bearded dragon can be an exciting and rewarding experience for reptile enthusiasts. By assessing factors such as size and growth rate, physical characteristics, shedding patterns, and teeth structure, you can gain valuable insights into your bearded dragon's age and better understand its specific care requirements. Remember to take into account individual variations and consult with a reptile veterinarian for a more accurate assessment of your bearded dragon's age. With this knowledge, you can provide optimal care and build a stronger bond with your scaly companion.
