How Long Does It Take a Bearded Dragon to Grow?

Bearded dragons are popular pets for many reasons, including their docile nature, unique appearance, and relatively easy care requirements. One question that many new bearded dragon owners ask is, “how long does it take a bearded dragon to grow?” In this article, we will explore the growth stages of bearded dragons, including the factors that can influence their growth rate.

Growth Stages of Bearded Dragons

Like many reptiles, bearded dragons go through several growth stages as they mature. These stages are characterized by changes in their size, appearance, and behavior. The growth stages of a bearded dragon are as follows:

Hatchling Stage

Bearded dragon hatchlings are typically around 3-4 inches in length and weigh only a few grams. They are born with a full set of teeth, sharp claws, and a distinctive pattern of dark stripes and bands. During the hatchling stage, bearded dragons are highly active and spend much of their time exploring their surroundings.

Juvenile Stage

As bearded dragons grow, they enter the juvenile stage, which typically lasts from 3 to 12 months of age. During this stage, bearded dragons undergo significant growth and development. They may double or triple in size and develop a more muted coloration with less distinct banding. Juvenile bearded dragons are still highly active but may begin to show signs of a more docile nature.

Sub-Adult Stage

The sub-adult stage of bearded dragon growth typically lasts from 12 to 18 months of age. During this stage, bearded dragons continue to grow and develop, although at a slower rate than during the juvenile stage. They may begin to show signs of their adult coloration, which is typically more vibrant and distinct than their juvenile coloration.

Adult Stage

Bearded dragons reach their full adult size at around 2 years of age. Adult bearded dragons can range in size from 16 to 24 inches in length, with males typically being larger than females. They have a distinctive appearance, with vibrant coloration, prominent spikes, and a beard-like flap of skin under their chin.

Factors That Can Influence Bearded Dragon Growth

While the growth stages of bearded dragons are relatively consistent, the rate at which individual bearded dragons grow can vary depending on a range of factors. Some of the most significant factors that can influence bearded dragon growth include:


Like any living creature, bearded dragons inherit certain traits from their parents that can influence their growth and development. Some bearded dragons may be genetically predisposed to grow more quickly or slowly than others.


A bearded dragon’s diet is a crucial factor in their growth and development. A diet that is deficient in essential nutrients can lead to stunted growth or other health problems. It’s important to provide bearded dragons with a balanced diet that includes a mix of insects, vegetables, and fruits.

Environmental Conditions

The temperature, humidity, and lighting conditions in a bearded dragon’s enclosure can also impact their growth rate. Bearded dragons require a specific temperature range and UV lighting to thrive. Failure to provide these conditions can lead to a slower growth rate or other health problems.


In conclusion, the length of time it takes a bearded dragon to grow depends on several factors, including genetics, nutrition, and environmental conditions. While the growth stages of bearded dragons are relatively consistent, the rate at which individual bearded dragons grow can vary widely. By providing proper nutrition, lighting, and environmental conditions, bearded dragon owners can help ensure that their pets grow and develop at a healthy rate.
