How Big Do Bearded Dragons Get? Don´t Be Shocked

a couple of years ago

How Big do bearded dragons getHow big do bearded dragons get? This is a very important question. Bearded dragons are one of the most popular pet reptiles you can find. Most of them are very calm and get used to you quickly. Adult bearded dragons should eat vedgetables most of the time and only 2 or 3 times crickets for example, which makes them even more appealing for people who do not have a thing for crawlies.

However bearded dragons might be very popular, but you can´t just set up a small tank for them and forget about it. There are a lot of preparations to make and there is a lot to know about bearded dragons before you actually buy one.

How big will your beardie get?

So this is the actual question in this post: How big will your beardie get? It is so important to know that, because you need to get the right tank size for your beardie and you need to know how much space you are going to need for your bearded dragon in your house.

Bearded dragons normally are 12 to 24 inches in length, the tail included. However the length of your bearded dragons depends on a lot of factors.

  • The bearded dragon species
  • The state of health of your pet
  • The diet: How many times do you feed your pet / what do you feed?
  • The sex of your bearded dragon

This makes the difference

The sex or your bearded dragon
If you get a male bearded dragon, you should know that your beardie most probably is going to be a big boy, since male beardies are always bigger then the females.

The species
The most popular bearded dragon, the Pogona Vitticeps (that´s the common bearded dragon) is not even the biggest species of the bearded dragons. The species Pogona Barbata lives in the east in Australia. You can find the biggest beardies there and this species can get up to 29 inches long (75cm) although this length is very rare.bearded dragon size

Here are the other species:

  • Pogona Minor Mitchelli size 18 inches
  • Pogona Minor Minor size: 14 to 18 inches
  • Pogona Nullabor size: 14 inches
  • Pogona Henrylawsoni size: 12 inches
  • Pogona Minor Minima size: 12 inches
  • Pogona Microlepidota size: 4 to 6 inches

The food

How much and what you feed your bearded dragon has a big impact on the growth of your dragon.

However do not get me wrong here. You can´t play Frankenstein and create a monster by feeding your pet tons of crickets. It does not work that way.

If you feed your bearded dragons tons of insects it won´t grow as big as you want. It will make your bearded dragon sick and it will become fat. Most probably your bearded dragon will suffer from health issues in the future if you do that.

On the other side, if you feed your bearded dragon less, it will most probably stay smaller. I would not do that, but it won´t kill your beardie. Think about that: Bearded dragons won´t find food every day in the wild of Australia. Some will find more and get bigger, some will find less and stay smaller, that´s nature.

However I do recommend to always offer a normal amount of food.

The state of health

Bearded dragons who are sick won´t grow fast and they most probably won´t get as big as a normal beardie. So make sure that your bearded dragon is always a healthy little boy … or girl 🙂

It is a myth that bearded dragons grow to the size that their environment allows!

bearded dragon bigA lot of people think that most reptiles and similar creatures would only grow as big as the size of their environment allows. If you believed that till now, don´t feel bad about it. There was a time when I believed that as well.

When I was a kid, my parents got me and my sister two turtles. They bought a small tank for them, because they thought that they would stay small then. However that was not the truth. The turtles felt great and became bigger and bigger. Eventually they became so big that my parents had to give them away since we had no space for them in our house.

That was a sad moment and I do not want you to experience the same, that´s why I am telling you this.

If your bearded dragon won´t grow in a smaller tank, it probably has something to do with other factors. (Food, Lighting etc.)

Further they need space and they won´t feel good in a small tank. That can have an impact on the growth of your beardie and of course it has an impact on the health of your bearded dragon.

Don´t be shocked, but don´t be afraid either

Big bearded dragons can get up to 24inches long, however there are a few who can get even bigger. Especially in the last time I´ve seen very big beardies in pet shops. So don´t be shocked if your dragon grows like hell.

On the otherside, don´t worry! Most bearded dragons stay smaller than that. Only a few get really, really big.

If you need a complete habitat for your bearded dragon, have a look at this article here. I compile complete terrariums which are ready for your dragon. Simply choose your budget and get the best tank for your money: Create a habitat for $140. Or Create a habitat for $360.

All in all I have to say, that if you do your research and prepare for your bearded dragon in the right way, you can´t do anything wrong, so don´t be afraid of the size of your beardie. Make sure that you have enough space and everything is going to be allright.
