How Big Will a Bearded Dragon Get? [Determined By 3 Factors]

Bearded Dragons grow very quickly in their first year of life, typically gaining 1-3 inches in length and 10-80 grams in weight each month between four and six months of age. After the first three months, growth slows to 1-2 inches a month until they reach their full size between 8 and 18 months of age. This full size is typically 16-24 inches in length and up to one pound in weight.

Growth Rate of Bearded Dragons

11 Inches in First 3 Months

A baby bearded dragon can grow up to 11 inches in their first three months of life. This speedy growth rate is important for the health and development of your pet. It’s also important to note that this growth rate is accelerated in the hatchling (0–2 months) phase, in which they grow at around 2 inches per month and reach 8–11 inches. After this initial growth period, the bearded dragon’s growth rate slows down until it reaches full size between 8 to 18 months.

Full Size After 8-18 Months

When a bearded dragon reaches 2 months old, they enter the juvenile stage and their growth rate will increase rapidly. Depending on the species, they may reach their full size after 8-18 months.

A full-size beardie will measure between 16 and 24 inches long and can weigh up to 1 pound. This length and weight are considered normal for an adult bearded dragon.

However, there are a few factors that can affect their size, including genetics, gender, and species. Understanding these factors can help you better manage your bearded dragon’s growth rate.

Factors Affecting Size


Genetics play a vital role in determining the maximum size a bearded dragon can reach. The size of a bearded dragon is largely determined by its parents’ size, and these inherited characteristics can be passed down from generation to generation.

Males are usually longer than females and will reach a full size between 8-18 months.


One of the key factors in determining how big a bearded dragon will get is its species. The most common bearded dragon kept as a pet is the Pogona vitticeps, more commonly known as the Central or Inland Bearded Dragon. This species grows to be 16-24 inches long.

On the other hand, the Pygmy Bearded Dragon (Pogona henrylawsoni) is much smaller, reaching only 4-6 inches in length as an adult.

Knowing the size of your bearded dragon’s species can help you determine if it is growing at a healthy rate. It will also help you understand how big it will get and whether or not it’s the right pet for you.

Helping Your Bearded Dragon Grow to a Full Size

In order to help your bearded dragon reach their full size, there are a few things you can do.

Proper diet and nutrition, appropriate heating and lighting, and calcium supplementation are all key factors in helping your bearded dragon reach its maximum size.

Providing a balanced diet with a variety of proteins, vegetables, and fruits will ensure that your pet is getting all of the nutrients it needs to reach its full size. Bearded dragons require UVB lighting and a basking spot of 90-110 degrees Fahrenheit in order to absorb the calcium from their food. Finally, providing a calcium supplement will ensure adequate calcium absorption for healthy growth.

By following these steps, you can help ensure that your bearded dragon will reach its full size.

Provide the Proper Diet

Providing the proper diet for your bearded dragon is essential for them to reach their full size potential. Bearded dragons are omnivorous, meaning they eat both plant and animal-based foods. The majority of their diet should consist of veggies and animal-based proteins such as crickets, cockroaches, worms, and other small creatures. You can also give them a small amount of fruit from time to time.

Be sure to properly chop the fruits and vegetables into small pieces to ensure they are able to digest them properly.

It’s important to feed your bearded dragon in moderation. Too much food can lead to health issues, so be sure to monitor your dragon’s diet and stick to a regular feeding schedule.

Proper Heating and Lighting

Proper heating and lighting is also essential for your bearded dragon’s growth. A UVB light bulb should span 2/3 to 3/4 of the enclosure size, and provide 100 watts of heat. This will help your bearded dragon get the necessary UVB rays it needs to thrive.

A basking area should be provided in the tank for your pet, with a temperature between 95 and 110 degrees Fahrenheit. This will provide the warmth needed for your bearded dragon to be comfortable and grow to its full size.

Calcium Supplementation

Calcium supplementation is an essential part of helping your bearded dragon grow to its full size. Hatchlings need to get supplements every day while juveniles should get it in their diet.

Talk to your veterinarian about the right amount of calcium supplementation and how often your bearded dragon needs it.

With all these factors in place, your bearded dragon can grow up to two feet in length and be a healthy, happy pet for many years to come.

How to Measure Your Bearded Dragon

Measuring your bearded dragon is an important part of tracking its growth. To get an accurate measurement, you should measure your dragon from the tip of its head to the tip of its tail. Picking a time when your dragon is less active is recommended as it will make the process easier and more accurate.


When it comes to measuring a bearded dragon’s length, it is relatively easy. Simply pick up the dragon and place them next to a tape measure or ruler. A rule will be fine for the first few months, but eventually you’ll want to switch over to a tape measure. When using a tape measure, pull it out to at least 35 inches before placing your beardie next to it.

Most bearded dragons will weigh between 380 to 510 grams when fully grown. Baby bearded dragons hatch at a tiny four grams and measure just three inches long when they hatch. As they grow, their weight should increase rapidly, and they should reach between 380 to 510 grams once fully grown. If your bearded dragon’s weight is not increasing or fluctuates greatly, consult a veterinarian to ensure they are healthy and properly cared for.

The easiest way to weight your bearded dragon is with a digital food scale that can weigh in grams. Since bearded dragons don’t weight much more than a pound, weighing in grams is a much easier method.
