How Big Do Bearded Dragons Get?

If you’re considering a bearded dragon as a pet, you probably have a lot of questions. “How big do bearded dragons get?” is definitely something you should ask before you bring one home. You need to make sure you have enough room for one, of course. And size is one indicator of health, so you should know what to expect. 

In this post, we discuss how fast bearded dragons grow and how big they can get, as well as some factors that affect their size and weight.

Please note we are discussing the Pogona Vitticeps species of bearded dragon, which is the most common when it comes to pets. Various species have various growth expectancies. Taking your dragon to the vet regularly for checkups will help you track your dragon’s growth and address any issues.

How Fast Do Bearded Dragons Grow?

Bearded dragons grow a lot during their first year of life! Here’s what you can typically expect with length: 

  • Hatchlings are about 3 inches long.
  • Babies range from 3 to 9 inches long. As they grow, they primarily need insects for protein in their diet.
  • Juvenile dragons grow 1 to 3 inches per month, typically when they are between 3 and 11 months old. They sprout from 8 or 9 inches up to 24 inches long. This is the time when the most rapid growth occurs. Your juvenile will probably be eating a lot during this stage! 
  • Adult dragons stop growing when they are 12 to 18 months old, although some dragons continue growing until they are 24 months old. This is a big reason why adult dragons need more veggies and greens, and less protein in their diet. Otherwise, they will be at risk for obesity. 

What Is a Healthy Weight for a Bearded Dragon? 

Bearded dragons gain quite a bit of weight as they grow. Here is the range you can expect per age: 

  • Babies weigh 4 to 6 grams, reaching up to 20 grams by 3 months.
  • Juveniles between 3 and 11 months gain a lot of weight as they grow, starting around 20 grams and ending up around 400 grams (roughly 14 ounces).
  • Adults may weigh 400 grams or more.

Pro Tip: Regular vet checkups are important to make sure your dragon is growing at a normal pace.

It is possible for bearded dragons to become obese, especially if they are eating a lot of feeders and getting little exercise. Sadly, this can easily happen for dragons in captivity if their owners are not informed about proper care.

Provide your dragon with a healthy diet, an appropriately sized tank, and exercise to prevent obesity, as this can cause health issues for your dragon. 

If your adult dragon weighs over 500 grams, keep an eye out for any signs of obesity such as very thick tail base or stomach dragging on the ground. 

Factors That Influence How Big a Bearded Dragon Can Get

Every dragon is different, of course, so it’s impossible to pinpoint exactly how big your dragon will get. But there are some factors that can influence growth, for the better or worse. These include:

To state the obvious, it’s important to give your dragon proper care and closely recreate his natural environment. A dragon on a balanced diet in a healthy environment has the best chance of growing to his full potential.
