Bearded Dragon Vivarium Size: Facts & Figures

As a proud owner of a bearded dragon, I’ve come to learn that providing a proper living space is essential for their health and well-being. With this in mind, I’d like to discuss the importance of bearded dragon vivarium size, offering insights and recommendations in ensuring your scaly friend has the ideal space to thrive.

So, let’s delve into the exciting world of bearded dragon habitats and learn about creating the perfect home for these fascinating reptiles.

Bearded Dragon Vivarium: What Is It?

A vivarium, in general, is an enclosed space designed to mimic the natural habitat of a specific animal, promoting its well-being and proper development. Precisely, a bearded dragon vivarium is an enclosure tailored to meet the unique requirements of these fantastic reptiles, native to the arid environments of Australia.

Essentially, a bearded dragon vivarium should cater to their specific needs, such as temperature, humidity, space for basking, and ample room for movement. Understanding these requirements and designing a suitable living space is crucial for ensuring the health, happiness, and longevity of your bearded dragon companion.

Why Does Size Matter for Bearded Dragons?

The size of a bearded dragon vivarium has a significant impact on their overall health and happiness. Reptiles, like bearded dragons, need ample space to move, explore, and express their natural behaviors. A cramped living space can lead to various issues, such as undue stress, limited exercise, improper body temperature regulation, and even stunted growth.

Moreover, an adequately sized vivarium allows you to set up proper temperature gradients, essential for bearded dragons to help them thermoregulate their body temperature. It also makes it easier to maintain a clean, hygienic environment, significantly reducing the risk of potential health issues.

Ideal Vivarium Size for Baby Bearded Dragons

When it comes to baby bearded dragons, choosing the right vivarium size is crucial to ensure their well-being and optimal growth. It is generally a good idea to start with a smaller-sized vivarium for easier monitoring and maintaining a secure environment for your young bearded dragon.

For baby bearded dragons (0-5 months old), an enclosure measuring 20-40 gallons, approximately 30 x 12 x 12 inches, should be sufficient. This size provides enough space for easy movement, proper temperature gradients, and simple maintenance.

However, keep in mind that baby bearded dragons grow quickly, and you’ll probably have to upgrade to a larger vivarium within a few months. Thus, planning or investing in a bigger enclosure might be a wise choice to save time and resources if you can ensure proper monitoring during their early stages. This way, you’ll provide a habitat that can accommodate your bearded dragon as it matures.

Ideal Vivarium Size for Juvenile Bearded Dragons

As your bearded dragon progresses from its baby stage to a juvenile, it’s crucial to revisit its vivarium size and provide suitable living space for this next phase of growth. Juvenile bearded dragons typically range from 5 months to 18 months of age, and they continue to grow rapidly during this period, demanding a larger habitat that allows them more room to move and explore.

For juvenile bearded dragons, a vivarium measuring 40-75 gallons, with dimensions around 36 x 18 x 18 inches, is preferable. This size ensures there’s enough room not only for the dragon’s growth but also for the necessary accessories such as basking spots, UVB lighting, and hideouts.

A crucial factor to keep in mind is that due to their rapid growth, a juvenile bearded dragon may quickly outgrow this vivarium size. As they approach adulthood, consider gradually upgrading its enclosure to accommodate its increasing spatial demands. Remember, providing an appropriately sized habitat for every stage of your bearded dragon’s life contributes to its overall health and quality of life.

Ideal Vivarium Size for Adult Bearded Dragons

Reaching adulthood, your bearded dragon will have grown considerably, necessitating a substantial living space tailored to meet their increased spatial needs. Adult bearded dragons are typically above 18 months old and can reach up to 24 inches in length, emphasizing the importance of giving them plenty of room to roam, bask, and exhibit their natural behaviors.

For adult bearded dragons, a vivarium of at least 75-120 gallons, with dimensions approximately 48 x 18 x 18 inches or larger, is ideal. Remember that bigger is often better when it comes to adult bearded dragon enclosures. Providing ample room for movement not only reduces stress but also mitigates the risk of injuries or accidents involving enclosure accessories.

Additionally, a larger vivarium for your adult bearded dragon makes it easier to maintain proper temperature gradients, accommodate basking areas, and keep the environment clean and healthy. In summary, investing in a spacious vivarium for your adult bearded dragon is vital to ensure its well-being and a happy, thriving life.

Factors to Consider When Choosing a Vivarium Size

As we’ve discussed, a bearded dragon’s vivarium size plays an essential role in its overall health and quality of life. Keeping that in mind, here are a few factors to consider when choosing the right size vivarium for your scaly friend:

  • Bearded dragon’s age and size: Consider the age and size of your bearded dragon to determine the appropriate living space. Keep in mind their rapid growth, especially during the juvenile phase, and be prepared to upgrade the enclosure size accordingly.
  • Budget and space availability: Ensure that you have the financial resources and available room at home to accommodate a large vivarium, particularly for adult bearded dragons.
  • Ease of maintenance: A larger vivarium can make it easier to clean and maintain, allowing separate areas for basking, hiding, and feeding. Proper hygiene is crucial for your bearded dragon’s health.
  • Temperature gradient and accessories: Make sure the vivarium size you choose allows for a proper temperature gradient between the basking and cool zones. Also, ensure there’s enough room for accessories like basking spots, UVB lighting, and hideouts.
  • Unique needs of your bearded dragon: While we’ve covered general guidelines for vivarium sizes, it’s worth noting that individual bearded dragons may have different requirements based on their unique needs, activity levels, and preferences.

Common Mistakes When Selecting a Vivarium Size

Being a dedicated bearded dragon owner, you may be well-versed in the basics of vivarium sizes. However, there are some common mistakes you might want to avoid when selecting an enclosure for your beloved reptile companion. Let’s discuss a few of these common pitfalls to help you make the best decision for your bearded dragon:

  • Choosing an overly small vivarium: It’s essential to give your bearded dragon ample space to move, explore, and thermoregulate. An undersized vivarium can lead to a range of health problems, as well as contributing to stress and discomfort.
  • Not accounting for future growth: Bearded dragons grow rapidly, especially during their juvenile stage. Failing to anticipate their growth can lead to quickly outgrowing their enclosure and necessitating multiple size upgrades in a short span of time.
  • Neglecting the importance of height: While length and width are crucial factors in vivarium sizing, don’t overlook the importance of height. Bearded dragons love to climb and bask, so making sure there’s enough vertical space is essential to their well-being.
  • Inadequate temperature gradient: A common mistake when choosing a vivarium size is failing to ensure that it allows for a proper temperature gradient. Both the basking and cool zones should be easily distinguishable and maintain optimal temperature ranges for your bearded dragon.
  • Skipping on essential accessories: An oversized vivarium with insufficient accessories or hiding places can create a stressful environment for your bearded dragon. Make sure you fill the space with the necessary accessories to enrich their habitat and foster natural behaviors.

By being mindful of these common mistakes, you’ll be well-equipped to select the most suitable vivarium size for your bearded dragon, ensuring their health, happiness, and overall well-being.


In this article, we’ve explored the importance of bearded dragon vivarium size, diving into the ideal dimensions and factors to consider at various life stages. By understanding the unique needs of your bearded dragon and making well-informed decisions regarding their living space, you can significantly enhance their quality of life and ensure their health and happiness for years to come.

Avoiding common mistakes and considering the right factors will undoubtedly help you provide the best possible environment for your beloved reptilian companion. Your bearded dragon deserves the perfect home, so let’s ensure we create a suitable and comfortable habitat for our fascinating scaly friends.
