What Size Tank For Bearded Dragon


Are you considering getting a bearded dragon as a pet? If so, one of the most important decisions you will need to make is choosing the right tank size for your new reptile companion. Bearded dragons require specific environmental conditions to thrive, and providing them with a suitable enclosure is crucial for their health and well-being. In this article, we will explore the factors to consider when determining the ideal tank size for a bearded dragon and provide practical tips to help you make the best decision.

Benefits of a Properly Sized Tank

Before delving into the specifics, it is essential to understand the benefits of providing a bearded dragon with a properly sized tank. A suitable enclosure offers several advantages, including:

1. Comfort and Freedom of Movement: Bearded dragons are active reptiles that require ample space to move around, explore, and exercise. A spacious tank allows them to stretch their limbs, climb on branches, and exhibit their natural behaviors.

2. Stress Reduction: Providing a bearded dragon with a tank that meets their needs helps reduce stress levels. A cramped or restrictive environment can lead to anxiety and behavioral issues, such as aggression or self-harm.

3. Improved Health: The right tank size promotes good health in bearded dragons. Sufficient space allows for proper thermoregulation, which is crucial for their digestion, metabolism, and overall well-being.

4. Enhanced Quality of Life: A properly sized tank enables you to create a diverse and stimulating habitat. You can incorporate various decor elements, such as hiding spots, basking areas, and climbing structures, that contribute to the bearded dragon's enrichment and overall quality of life.

Now that we understand the importance of a well-sized tank, let's explore the factors to consider when determining the appropriate enclosure size for a bearded dragon.

Factors to Consider

1. Adult Size of the Bearded Dragon

One of the primary considerations when selecting a tank size for a bearded dragon is their adult size. Bearded dragons can vary in size depending on their age, sex, and genetic factors. On average, male bearded dragons reach a length of 18-24 inches, while females tend to be slightly smaller, measuring around 16-20 inches.

When determining the tank size, it is crucial to consider the maximum size the bearded dragon will attain. Providing a tank that accommodates their adult size from the beginning will prevent the need for frequent upgrades and potential stress associated with tank relocations.

2. Length and Width of the Tank

The length and width of the tank are crucial factors to consider. Bearded dragons require horizontal space to move around and explore their environment. A long and wide tank allows them to engage in natural behaviors, such as running, basking, and hunting.

A general rule of thumb is to provide a tank that is at least 1.5 times the length of the bearded dragon. For example, if you have a bearded dragon that will reach a length of 18 inches, the tank should be a minimum of 27 inches long. Additionally, the width of the tank should allow for comfortable movement and accommodate accessories such as branches and hiding spots.

3. Height of the Tank

While bearded dragons primarily inhabit the ground, they also enjoy climbing and basking in elevated areas. Therefore, the height of the tank is an important consideration. A taller tank allows for the inclusion of branches and elevated platforms, providing the bearded dragon with the opportunity to display their natural behaviors and explore their habitat vertically.

A tank height of 18-24 inches is generally recommended. This allows for the addition of climbing structures and ensures that the bearded dragon can't easily escape from the enclosure.

4. Activity Level and Behavioral Needs

Consider the activity level and specific behavioral needs of your bearded dragon when determining the tank size. Some bearded dragons are more active than others and require additional space to satisfy their energy levels. Similarly, if you plan to create a more elaborate habitat with plenty of hiding spots, basking areas, and climbing structures, a larger tank may be necessary to accommodate these elements.

Assess your bearded dragon's individual personality and preferences to ensure you provide them with a tank that meets their activity level and behavioral needs.


Choosing the right tank size for your bearded dragon is a crucial aspect of responsible pet ownership. A properly sized tank promotes comfort, reduces stress, improves health, and enhances the overall quality of life for your reptile companion. By considering factors such as adult size, length and width, height, and activity level, you can ensure that your bearded dragon has an optimal living environment.

Remember, providing a spacious and stimulating enclosure not only benefits your bearded dragon but also allows you to observe and enjoy their natural behaviors. So, when setting up a habitat for your new bearded dragon, make sure to prioritize their needs by selecting a tank size that provides them with the space and freedom they require to thrive.
