If you’ve never had a bearded dragon before, now’s the best time to learn as much as you can about the reptile before purchasing it

One of the first aspects to learn is the animal’s diet; what it should eat, how much, how often, etc

As you will soon see, there’s a fine line between feeding your dragon properly and overfeeding or underfeeding it, both of which come with different health problems

Average Weight for Bearded Dragon

The average weight for a bearded dragon revolves around 450-500 grams

We’re talking about an adult dragon, 18 months of age or older

This is also the average weight for a male, but females fall lower on the spectrum, typically below 400 grams

Here’s a chart of the different stages of a bearded dragon’s life with the respective body weight for each phase:

Bearded Dragon Age

This chart exemplifies the standard weight gain for a bearded dragon regardless of sex, so these values can vary depending on a variety of factors

Some dragons can reach 650 grams or more, especially larger males, while others remain below the 500-gram mark

It all depends on your dragon’s profile, diet, genetic background, etc

Signs of Overweighted Bearded Dragon

Bearded dragons can get overweight with ease, primarily because they have no self-control when it comes to eating

As juveniles, they eat several times per day and require one meal per day or every other day as adults

The signs suggesting that your bearded dragon is overweight include:

Fat deposits – These should be visible right away, informing you that your dragon’s diet is more calorie-rich than it should be

Bearded dragons store fat in their legs, tail, bellies, and under the chin, so check those areas first

In case of visible fat deposits, tweak the dragon’s diet to force the body to consume them

If that’s the case, your dragon may be overweight

The reptile may still be alert and healthy-looking, it’s just that it prefers to rest more

This is because the extra weight makes moving more strenuous, eventually discouraging the dragon from moving completely

This being said, you should always rely on the presence of fat deposits to diagnose your dragon’s health state

The following 2 points are only indicators of a weight problem if fat deposits are present

Signs of Underweighted Bearded Dragon

An underweight dragon is at more serious health risks than an overweight one

The clearest sign of an underweight problem is the dragon’s skinny appearance

You shouldn’t be able to see your dragon’s ribs and bones through the skin

Also, look for signs of saggy skin and lack of movement, as underfed dragons have very little energy to spend

However, as I’ve already mentioned, being underweight isn’t the real problem

The real problem is nutrient deficiency

If your dragon isn’t getting sufficient food, it will experience nutrient deficiency first and only after the signs of malnutrition will begin to appear

The problem is that nutrient deficiency is often deadly, because bearded dragons are prone to calcium deficiency

Severe calcium deficiency due to insufficient food or improper nutrition as a whole can degenerate into Metabolic Bone Disease which is lethal in advanced phases

Weighing Your Bearded Dragon

You ideally want to weigh your bearded dragon at different phases of its life to make sure it’s growing properly

You only need a kitchen scale for that, so long as you remember that some kitchen scales are capped at 500 grams

When preparing to weigh your bearded dragon for the first time, remember the following tips:

Baby and juvenile dragons are jumpier and more energetic; handle them with care to prevent them from escaping

Don’t hold your dragon’s tail during the handling, as the animal can freak out and lose it in the process

Use a tall container when weighing the dragon to prevent the reptile from running; most dragons take time to get used to the weighing process

You want to weigh your dragon more often when young because that’s when they grow faster

The dragon’s growth rate drops as the reptile matures, around 18 months of age

Keeping Your Bearded Dragon in Shape

The idea is to keep your dragon in shape so you won’t have to deal with any weight-related issues

Adjust the Meal Size and Frequency

First, you need to adapt to your dragon’s nutritional requirements

Baby and juvenile dragons eat far more often than the adults

A typical juvenile dragon may require 2-3 meals per day, while adults only eat once per day

As the dragon ages beyond the 18-month mark, it may even eat once every 2 days

Learn your dragon’s physiological needs and adjust the meal plan based on that

Only feed your dragon small portions each time, sufficient for the animal to consume with excitement

Once its eating excitement drops, you know the reptile has had its full

As a general idea, bearded dragons eat around 3-4 food items in one sitting whether that’s insects or fruit pieces

Meal size and frequency matters greatly in this sense

It’s also critical to learn your dragon’s nutritional requirements

Bearded dragons need more animal protein and fats when young and more fruits, veggies, and greens as they grow old

To consider some general values, the diet of baby and juvenile dragons consists of 80% insects and 20% fruits and veggies

The diet of a typical adult bearded dragon consists of 30% insects and 70% fruits and veggies

You should adapt to your dragon’s nutritional requirements and tweak its diet as it grows older

Bearded dragons also require commercial food, nutritionally optimized for them

So, consider gut-loading and dusting your feeder insects before serving them to your lizard

I recommend setting up an insect feeder tank to provide you with sufficient high-quality food daily

You should always watch your dragon’s food fiber content

These are generally present in fruits and veggies, which adult dragons need to eat plenty of

Fibers are great for preventing constipation and keeping the lizard’s digestive system in good condition

Bearded dragons need to remain physically active to stay in good shape

Also, make sure that your bearded dragons have sufficient moving space

You don’t want to keep your dragon in a small and claustrophobic setup

This will not only stress the animal, but limit its physical activity as well

The ideal tank size for an adult bearded dragon revolves around 55-75 gallons, depending on the reptile’s size and activity level

This allows you to vary your dragon’s layout the way you want it and according to your reptile’s needs

Finally, this is a pet you have here, so, feel free to engage in fun activities together once in a while

Not much, just enough to touch the dragon’s belly

This is an especially fun activity in sunny and hot days when dragons could use some bathing

Ball time – A ping-pong ball is often exactly what your dragon needs for some variation and physical activity

Don’t expect to teach your bearded dragon to fetch anytime soon, though

Handling – Sometimes, even handling your bearded dragon can help your reptile workout a bit

Just learn the difference between handling a baby vs

They will vary in size and weight significantly

You don’t need to do anything special during these handling sessions

Don’t hold your reptile pet if it squirms or seems reluctant to let you touch it

That means that the dragon may prefer solitude for the time being, needs more time to know you better, or maybe there’s something bothering it

You should always weigh and assess your bearded dragon’s health status frequently

Keep track of the reptile’s overall physical and mental health, assess its activity level, and check its overall behavior

By doing so, you will learn the difference between a healthy and an unhealthy specimen which often gives you the upper hand in case your reptile in unwell

Timely measures in case of sickness, nutrient deficiency, and other health-related problems are critical for avoiding more severe situations

You rarely get to see overweight or underweight bearded dragons in the wild

Food availability is also an important factor that keeps dragons in shape; it’s unlikely for a bearded dragon to find sufficient food to allow it to become overweight

Try to understand your reptile’s metabolic and nutritional requirements and stick to what fits their profile best

It is important to note, that whenever you measure your bearded dragon you must include their tail

A full-size bearded dragon will most often measure between 16 and 24 inches

These full grown bearded dragons will also most often weigh between 300 and 550 grams, with the average weight being around 400 grams

A bearded dragon grows to its full size by 18 months of age, at which point they are considered an adult and sexually mature

However, it is not uncommon for bearded dragons to be done growing by 12 months of age

Most bearded dragon owners will agree there are 3-4 primary age groups for a bearded dragon

Expect your bearded dragon’s growth rate to mirror the amounts in each category below… 

Baby Bearded Dragon Size

A new born baby bearded dragon will typically measure around 3 inches long and will weigh as little as 4 grams

Bearded dragons are regarded as “hatchling” from the moment they’re born through 2 months of age

Once they reach 2 months of age, hatchlings will typically have doubled or even tripled their length, and gained anywhere from 4 to over 30 grams

Juvenile Bearded Dragon Size 

A juvenile bearded dragon can range in size anywhere from 8 to 23 inches long and weigh between 20 and 400 grams

Juvenile bearded dragons are those that are between 3 and 11 months of age

These bearded dragons experience the MOST dramatic growth rate, with most having nearly reached their final size by month 11

This dramatic size range is due to the long 8 months of growing juveniles undergo

Sub Adult Bearded Dragon Size

Expect the average sub adult bearded dragon to measure between 15 and 24 inches and weigh between 300 and 500 grams

Sub adult bearded dragons are those that are between the ages of 12 and 17 months

During these months, a healthy bearded dragon’s size will change very little, if at all

For example, a sub adult bearded dragon may only grow an additional inch between 12 and 17 months of age

On top of this, they may only gain 20 grams

Adult/Full Grown Bearded Dragon Size

Although much bigger than their baby bearded dragon counterparts, adult bearded dragons are still a really manageable size compared to many other lizards

Not as small and frail as lizards like geckos, but smaller than iguanas and monitor lizards, their medium size makes them attractive to many pet owners who want a hardy yet small reptile

A full grown bearded dragon will typically be anywhere from 16 to 24 inches in length and will weigh on average between 300 and 550 grams

However, full grown bearded dragons can reach longer lengths, with some growing to be as long as 26 inches

As aforementioned, a beardie will be considered an adult bearded dragon at 18 months of age

It is at this point that 999% of owners will have their bearded dragon full size

Full grown bearded dragons that are male will almost always be a bigger size (longer) than full grown female bearded dragons

Males will typically measure 20 to 24 inches in size, whilst females will often measure 16 to 20 inches in size

As you may have already picked up on, full grown bearded dragons can vary amongst each other in size (weight and length) somewhat depending on a few factors

Because of this, there is no ONE size that is regarded as “normal”

An adult bearded dragon’s size is MOST determined by…

Enclosure quality & size

If you have adopted or are thinking of adopting a baby bearded dragon, be sure to cherish their baby size while it lasts!

Bearded dragons pretty much embody the old adage of “growing up too fast” with an astronomical growth rate witnessed in the first few months

Naturally, any new or prospective pet owner will want to know how long their pet will be growing for

Knowing such will allow for proper planning and strategy to ensure you have the time, energy, and resources to properly care for a baby for a specific amount of time

After all, what could be more overwhelming than to have your baby bearded dragon transform into an adult bearded dragon seemingly overnight?

So, just how long does it take a bearded dragon to grow?

And when do bearded dragons stop growing?

Although some dragons can continue growing a little bit into their second year of age, many dragons seem to dramatically slow down around 11 to 12 months, typically having reached their full size in length of anywhere from 15 to 18 inches!

Now, this isn’t to say that your dragon doesn’t have more growing ahead of them into their second year, but chances are, it is very little, as in an inch or two

Also, the speed at which your dragon will continue to grow will be so gradual you may not even notice it

So, don’t be surprised if their size doesn’t appear to change much aft 12 months

You can expect most bearded dragons to be 95% done growing by 12 months of age and 99-100% done by 18 months

Bearded Dragon Growth Rate

Obviously, this is in direct contrast to the growing boom witnessed within the first 6 months, with bearded dragons growing as quickly as an additional inch per week!

It should also be noted that around the year mark, give or take a few months, is when your dragon should start putting on some weight and bulking up

Expect your adult bearded dragon to begin filling out some and looking less lanky around the 12 month mark

Bearded Dragon Size Chart

Size (Length)

The bearded dragon size chart above will help give you a more specific idea of bearded dragon size by age

By consulting the chart, you will be able to better gauge by how long bearded dragons grow for and at what point this growth dramatically slows down

However, it is important to note that these lengths are all estimates and averages

So, if your bearded dragon’s size is shorter than the sizes listed below, it doesn’t necessarily mean they’re unhealthy or that their growth is stunted

Bearded Dragon Weight

Bearded Dragon Weight

Big, small, medium… there truly is no ONE accepted size for a bearded dragon to be

Just like with people, some bearded dragons are simply genetically inclined to be bigger

The important thing is you ensure your bearded dragon is not underweight or overweight and that if they are under 12 months of age, they are growing progressively and gaining weight each month

When they’re born, baby bearded dragons are tiny, weighing about the same as a single sheet of paper!

Yet, their size doesn’t stay small for long…

You see, these itty bitty babies can gain as much as 400x (or more!) their birth weight by the time they reach adulthood

And many of them will double their birth size within a week or less

On top of closely monitoring your bearded dragon’s length, you should also pay attention to their weight

How to Tell If a Bearded Dragon Is Overweight

An overweight bearded dragon will look especially round, with a belly that can be seen from above, fat legs, and a very full chest

If you believe your bearded dragon to be overweight, you should first check their tank’s temperatures to make sure they are where they need to be

If the temperatures get too high, this can lead to a bigger size bearded dragon, as the temps will trigger their appetite and cause them to eat more food than they would normally

As a reminder, you’ll want to aim for a basking spot between 95 and 100 degrees Fahrenheit for bearded dragons a year and older

To help your bearded dragon lose weight you can…

Only offer low fat feeders, such as crickets and hornworms

Feed more vegetables and less feeders

How to Tell If a Bearded Dragon Is Underweight

An underweight bearded dragon will have skin that looks wrinkly and hangs from their body

They will also have a torso that appears flat in size

A normal bearded dragon’s fat pads will be slightly raised

If you believe your bearded dragon is underweight and they are under a year old, start monitoring their weight immediately!

You’ll want to ensure they are gaining weight week after week and are not experiencing a plateau in their size

One of the most common causes for an underweight bearded dragon is a cold cage

If your bearded dragon isn’t able to warm him or herself, then they will likely experience a decrease in appetite

Make sure your bearded dragon’s lighting and temperature setup is appropriate for their specific age

To help your bearded dragon grow in size and gain weight you can…

Offer feeders high in fat, such as superworms, waxworms, and butterworms

Supplement their feedings with a homemade bearded dragon slurry

These estimations in this bearded dragon growth chart are just approximations

However, they represent the majority of bearded dragons within these categories, and as such, depict healthy lengths for each specific age range

At one year old, your dragon should be anywhere from 16 to 18 inches long on average

It is at this age that your dragon will also begin to significantly slow down in their growing process

However, by 24 months of age they can grow to be as long as 24, 25, or even 26 inches!

However, more times than not, your dragon will reach it’s full length by around 18 months

Please note the Bearded Dragon Growth Chart above to get an idea of where the average bearded dragon falls in terms of length through the first 18 months of their life

If your bearded dragon is below average size and weight (see the bearded dragon size chart and bearded dragon weight chart above for reference)…

Chances are there’s either something wrong with their diet, their habitat isn’t set up correctly, or you’ve let them go through brumation at too young of any age

Read below to discover how each of these issues can lead to a small and underdeveloped bearded dragon!

Bearded Dragon Growth Problem #1: Inadequate UVB Exposure

If your dragon’s habitat doesn’t have a proper UVB bulb, then this can definitely lead to slower or stifled growth

Bearded dragons who don’t get adequate levels of UVB are not able to appropriately absorb calcium from their diet

This can lead to a bounty of serious health problems

Without calcium, bearded dragons can…

Experience stunted growth

Develop Metabolic Bone Disease

Also, without the right UVB setup, your bearded dragon can also have a suppressed appetite, leading to stunted growth

🤓 Expert Tip: To ensure your bearded dragon is absorbing optimal amounts of UVB, you’ll need to change their bulb(s) every 6 months

Now, if your bearded dragon has a high quality mercury vapor bulb, you can typically wait a little longer, say 6-10 months before changing it out

Just be sure to watch your pet’s energy levels, as they can become lethargic as bulbs weaken

Bearded Dragon Growth Problem #2: Insufficient Diet

Unlike more mature bearded dragons, babies need virtually as much protein as they will eat to grow up both big and strong

If your baby bearded dragon is under 3 months, you should be feeding them crickets 5 times a day for 5-10 minute intervals, allowing them to eat as much as they like

And although greens and salad are a staple in a bearded dragon’s diet, they don’t really become important until around 12 months of age

It is at this point that your bearded dragon will have most likely reached or nearly reached their full size, and as such, they will not be needing nearly as much protein

Bearded Dragon Growth Problem #3: Brumation

Although brumation is a perfectly normal bearded dragon behavior, allowing it to happen when your bearded dragon is still growing can irreversibly stunt their growth and lead to them being a smaller size

Brumation, which is essentially the reptile version of hibernation, is when a bearded dragon hunkers down and sleeps for long periods of time as they anticipate winter

When a dragon goes through brumation, they tend to lose quite a bit of weight as they spend a good deal of time sleeping and therefore, not needing food

Brumation can significantly stunt the growth of a younger dragon and as such, should be avoided if possible

Avoid brumation by ensuring the temperatures in the dragon’s cage stay where they should be year-round (both during night and day) and by also making sure the lighting cycle is normal as well (10 – 12 hours of light a day, every day! )

Bearded Dragon Growth Problem #4: Disease or illness

If your bearded dragon happens to become sick whilst they’re still growing, then the can experience stunted growth

Often times, sickly bearded dragons experience a loss of appetite

And if a growing bearded dragon is not consuming the food their body needs, then they can become weak and stop growing

Additionally, internal parasites can also lead to slower or stunted growth as they will rob your bearded dragon of the nutrients they consume

If your bearded dragon is experiencing diarrhea or their waste is abnormally smelly – yet their diet hasn’t changed – they may have parasites

Knowing what healthy bearded dragon poop looks like, can help you better recognize the potential presence of parasites

You can almost always prevent an illness by ensuring your bearded dragon’s diet and habitat are on point

To Keep Your Bearded Dragon Healthy And Help Them Grow… 

Ensure temperatures are where they should be

Offer calcium and multi vitamin supplements

Feed a proper, well-rounded diet

If you manage to do all of the things listed above, your bearded dragon should enjoy the best possible chances of growing up big and strong!

🤓 Expert Tip: Knowing the signs of a sick bearded dragon can make all the difference in not only their recovery BUT also how much (or how little) you need to spend to get them feeling better

Brush up on the most common signs of sick bearded dragon to ensure you’re prepared in the event your pet becomes ill

Wrapping Up How Big Do Bearded Dragons Get

All bearded dragons come into the world the same way, tiny, fragile, and weighing no more than a handful of grams

However, with the right diet and care, their growth rate skyrockets as they double, triple, and quadruple in size over a few short months!

And while there is no one size that is the standard for bearded dragons, all owners should monitor the growth of their pet to ensure they don’t become underweight or overweight

Additionally, those that own babies or juveniles should regularly weigh and measure their pets to ensure their growth rate is not being stifled

And should they find their bearded dragon to have stopped growing before a year’s time?

Immediate action should be taken to ensure that the lighting and temperature setup is appropriate, their diet sufficient, and their pet healthy and free from parasites

Now, make sure you know all there is about how long bearded dragons (should) live!
