1 Year Old Bearded Dragon Size: Comprehensive Guide

Are you wondering how big your one year old bearded dragon should be?

Well, the average size of a one year old bearded dragon is 16-18 inches long!

It’s amazing to think that in just one short year, these little reptiles can grow so much.

But, while some dragons may reach this size quickly, others may take longer or even remain smaller.

That’s why it’s important to understand all the factors that influence a dragon’s growth rate and size.

In this comprehensive guide, we’ll cover everything from measuring your dragon to common health issues associated with their size.

So let’s get started on learning about the incredible world of bearded dragons!

What is the Average Size of a One Year Old Bearded Dragon?

Wondering how big your pet will be at a year? Check out this guide to get a better idea of the average size for one-yr-old bearded dragons!

Bearded dragons typically fall in the range of 16 to 20 inches in length when they are one year old. As bearded dragons grow, their housing requirements and exercise needs change as well. Therefore, it’s important to understand their size before purchasing or creating an appropriate habitat for them.

Bearded dragons have distinct life stages that are characterized by both physical changes and behavioral changes. As they reach maturity, they’ll start to display signs of aggression such as hissing and bobbing of the head.

It’s also important to note that female bearded dragons tend to be larger than males when reaching one year old. Although it can vary from dragon to dragon, females may grow up to 24 inches while males may stay around 18 inches long.

Knowing these averages can help you determine what type of enclosure your beardie will need throughout its life.

Factors That Influence Bearded Dragon Size

When it comes to understanding how factors influence the size of a bearded dragon, there are three key areas to consider: genetics, diet and nutrition, and sex.

Genetics play an important role in determining a bearded dragon’s eventual size; however, proper nutrition and diet can also affect their growth rate.

Moreover, male dragons tend to be larger than females due to differences in hormone production and other biological processes.


Genetics play a key role in determining the final adult size of a reptile, making it an important factor to consider when selecting a pet. Bearded dragons are no exception. Their size is largely influenced by genetics, as they are products of their parents’ hereditary traits and genetic diversity.

When looking at two bearded dragons that appear identical in coloration and patterning, it is possible for one to be larger than the other due to differences in their respective genetic makeup. Generally speaking, offspring will inherit half of their gene from each parent; therefore, two siblings may have very different sizes depending on which particular genes they inherited.

For example, if one parent carries genes for larger size while the other carries genes for smaller size then both offspring may display mixed characteristics from both parents with varying sizes resulting in greater or lesser than average adult size. Ultimately, this makes understanding the genetics of your dragon’s parents an essential component to predicting its potential adult size.

Diet and Nutrition

Nutrition is key to a reptile’s health and growth, so it’s important to ensure your pet gets the proper dietary requirements for its species.

When it comes to bearded dragons, their diet consists of a variety of live insects and vegetables. Providing them with plenty of fresh food is crucial for maintaining their healthy growth and hibernation needs.

Vegetables such as kale, butternut squash, collard greens, endive lettuce, sweet potatoes, and bell peppers are all good choices that provide essential vitamins and minerals. Furthermore, they should be supplemented with calcium-rich foods like mealworms or crickets dusted with calcium powder.

Temperature control also plays an important role in dietary needs for bearded dragons; warm temperatures help stimulate appetite while cooler temperatures can cause loss of appetite or even hibernation if taken too far. During colder months you may need to increase the amount of higher calorie foods like small wax worms or super worms in order to maintain healthy body weight.

Additionally, it’s important not to overfeed your dragon as this could lead to obesity which can have serious health implications down the road. It’s best practice to consult with a veterinarian if you’re ever unsure about what type of nutrition plan would work best for your dragon.


Knowing the sex of your bearded dragon can help you provide more tailored care and ensure its wellbeing. There are various methods for sexing these reptiles, which include looking for physical cues like femoral pores in males, visualiating the hemipenal bulge in males, observing behavior patterns that differ between the genders, and by using a DNA test.

Understanding gender differences is important for providing an optimal environment for your pet. Here’s a deeper look at each way to determine your dragon’s gender:

  • Looking For Physical Cues – Female dragons usually have smooth scales around their vents while male dragons will have two rows of femoral pores along either side. Also, male dragons may have larger heads than female dragons and they tend to be larger overall.

  • Visualizing The Hemipenal Bulge – With gentle pressure from behind the vent area of the dragon, you may see a projection on either side which indicates that it is a male as only they possess this feature.

  • Observing Behavior Patterns – Male bearded dragons typically display territorial behaviors such as head bobbing or arm waving when competing with other males while females are not as likely to demonstrate these behaviors. Females also tend to become more aggressive during breeding season while males may become more docile in comparison.

  • Using A DNA Test – This is another surefire way to determine gender without any guesswork involved but it does require some additional cost and time so consider whether or not this option is right for you depending on what you need to know about your dragon’s sex.

Understanding how to accurately identify your reptile’s gender can help support its health and wellbeing long-term since different sexes require different levels of care depending on their age and size. Taking proactive steps now will pay off later as you get better acquainted with your pet!

How to Measure a Bearded Dragon

Measuring a bearded dragon is an important part of understanding its growth. Did you know that they can grow up to 24 inches in length? Knowing the size of your bearded dragon will help you make sure their enclosure setup is adequate and suitable for temperature regulation.

You can measure your bearded dragon by using either a flexible ruler or measuring tape, but it’s important to be careful when doing so because you don’t want to stress out the dragon. To ensure accuracy, you should measure from the top of their head to the tip of their tail while they are standing on all fours. You should also take into account any additional body parts like spikes or crests when making measurements. Once done, record your results so that you can track how your reptile grows over time.

It’s also important to note that male bearded dragons tend to be larger than females, with males reaching lengths up to 24 inches and females up to 18 inches long. This means that if you have a female beardie, her enclosure setup doesn’t need to be as large as one for a male since she won’t require as much space.

By properly measuring and tracking your beardie’s growth, not only will this help you provide them with an ideal environment in terms of temperature regulation and enclosure setup, but it will also give you peace of mind knowing that your pet is healthy and thriving!

Health Concerns for Smaller Bearded Dragons

Paying close attention to your bearded dragon’s health is essential for ensuring they stay happy and healthy, especially if they’re a smaller size. Age-related health concerns are more common in smaller dragons due to their short lifespan and rapid growth.

It’s important to be aware of the signs that indicate when something is wrong, such as changes in behavior or appetite, weight loss or gain, skin discoloration or lesions, and respiratory problems.

By being attentive to these issues, you can ensure your dragon stays healthy as it grows older and prevent stress-related illnesses from developing. Stress management is also important for small bearded dragons since their delicate systems can be easily affected by changes in environment or diet.

Creating an optimal habitat with appropriate temperature and humidity levels, providing nutritious food sources regularly, and avoiding any sudden changes will help keep your pet relaxed and content.

Common Health Issues for Larger Bearded Dragons

As your bearded dragon grows bigger, it’s important to be aware of common health issues that may arise.

Temperature regulation and stress levels are two key factors that can affect larger dragons since their size means they can’t regulate temperature as easily as smaller ones. This could lead to overheating or even hypothermia in extreme cases.

If your dragon is exposed to temperatures outside its ideal range for long periods, it can cause serious health concerns such as respiratory infections or metabolic bone disease (MBD).

In addition to temperature regulation, increased stress levels due to being handled too often or housed in an unsuitable enclosure can also adversely affect the health of your bearded dragon.

Stress can manifest itself through behavioural changes such as reduced appetite, aggressive behaviour or excessive hiding. It’s therefore important to make sure that both the environment and handling practices are suitable for your larger-sized pet.

Regular vet visits are also recommended so any potential health issues can be identified and addressed early on before they become more serious problems down the line.

How to Help Your Bearded Dragon Grow

You want your bearded dragon to grow up strong and healthy, so it’s important to understand the basics of proper diet and nutrition, as well as providing the right environment.

A balanced diet that includes a variety of live insects and vegetables is essential for supporting your pet’s growth.

And remember, the size of their habitat should reflect their age—baby dragons need smaller tanks that provide plenty of hiding spaces!

Proper Diet and Nutrition

Ensuring your pet dragon is eating the right food will keep them healthy and happy. For example, a well-balanced diet for an adult dragon should include a variety of insect proteins, leafy greens, and vegetables:

  • Insect Proteins: crickets, mealworms, wax worms (occasionally). Ensure you’re feeding your dragon insects that are appropriately sized for their size.

  • Leafy Greens: kale, collard greens, endive. Offer to your dragon no more than once per week as part of its diet.

  • Vegetables: squash, bell peppers, sweet potatoes. Peel off any skin before feeding it to your dragon as this can cause indigestion.

Your pet bearded dragon’s diet should also be supplemented with calcium powder and multivitamins regularly. Additionally, they require proper lighting requirements in order to digest their food properly. This means ensuring the habitat size has ample space for UVB bulbs or other natural light sources to reach them.

With the right combination of proteins, vegetables, and minerals in its diet along with proper lighting and habitat size requirements, your bearded dragon will remain happy and healthy!

The Right Environment

Now that you understand the diet and nutrition for your bearded dragon, it’s time to discuss the importance of creating the right environment. Maintaining a healthy habitat is essential for their well-being and happiness.

Creating an environment which mimics their natural habitat will help them to thrive and live longer. Temperature control and lighting setup are two key components of any bearded dragon’s enclosure.

It is important to have a temperature gradient in order to provide both hot and cool spots in the enclosure. This can be achieved with a bulb or ceramic heating element at one end of the tank and a UVB light over all areas so they can bask in sunlight as they would naturally do in the wild.

Additionally, it’s important to keep humidity levels low; too much humidity can cause respiratory issues for your little reptilian friend. Be sure to also create hiding places for your bearded dragon, such as plants or rocks, so they feel secure while exploring their new home!

Tips for Keeping Your Bearded Dragon Healthy

Maintaining your pet’s health should be a top priority, and this section will provide you with some helpful tips to do just that.

The key to keeping a healthy bearded dragon is providing it with the right environment. This includes following lighting regulations for the enclosure size and making sure the temperature stays between 85-90°F during the day and 75-80°F at night.

Additionally, it’s important to provide a balanced diet of insects, greens, vegetables, and calcium supplements. Make sure to dust their meals at least three times per week with calcium powder or other multivitamins specifically formulated for reptiles such as bearded dragons.

It’s also important to make sure your dragon has plenty of clean water available in its enclosure every day. Change out any dirty water daily and use a shallow dish so that your pet won’t accidentally drown while drinking from it.

Lastly, keep an eye on your dragon’s behavior – if they seem sluggish or off balance then take them in for a checkup right away! A regular vet visit can help detect any potential issues before they become more serious problems.

With these simple tips in mind, you can ensure that your year old bearded dragon remains happy and healthy!
