It is recorded that such affected beardies only grow to 16 inches, and their weight is approximately 0.62 pounds. Such defects can happen due to several factors, such as insufficient light exposure, unhealthy feeding, or harmful parasitic attack.

Growing Phase

During the growing phase, any animal grows according to its inherited genes and the nutrition they get from food. However, sometimes it is found that the genes tend to have a good height, but the lack of proper nutrition may hinder the growth. The growth rate for any healthy baby bearded dragon is faster than the other phase of life. 

  • In the first 3 months after birth, beardies grow 3 to 11 inches, which is perfect for them. They gain around 4-6 inches in length every month.

It makes them suitable to reproduce and become sexually active without lagging. Also, the offspring from a healthy beardie is usually free from parasitic attack, and they gain a tendency to stay fit. 

Speedy growth is crucial since their physical appearance makes them rave. If they are small, they will be considered less potent than the other bearded dragons, making them less active and less interested in reproduction. 

The growth rate of a beardie is tremendous. You will see them smaller today and later find them as a giant in just a few months. During their rapid growth phase, beardie shred twice or thrice a month.

The growth of a bearded dragon tells a lot about the health of a beardie. However, sometimes just looking at the length grown will be insufficient for the owner or breeder since it doesn’t justify the overall health of a beardie.

4 Factors that Affect the Size of A Bearded Dragon

Multiple factors can affect the growth of a bearded dragon. Any new beardie owner who doesn’t know about a beardie’s growth patterns must consider these factors for an easy understanding of the body and growth patterns of a bearded dragon. These factors can influence the growth of a bearded dragon either positively or negatively. Let’s consider some of the factors.

1: UV Lightening

UV lighting is one of the most crucial factors when looking for bearded dragon growth. UVB from the sun or a special kind of UV light helps prevent stunted growth among bearded dragons.

UV consists of nutritional values required for a bearded dragon to grow properly. The deficiency of UV lighting exposure can cause stunted growth in bearded dragons. Exposure to UV lighting helps in the rejuvenation of skin cells and also makes the bone stronger since it activates the formation of vitamin d in the body.

2: Genetics

Genetics plays a crucial role in the growth of an organism; it aids in deciding the characteristics and body of an organism. Similar to humans, genetics have a major influence on a beardie’s height. The largest bearded dragon ever recorded is a German bearded dragon. If the genes carry good height characteristics, they will surely be visible in the offspring beardie.

Genetics also work together with the nutrition an animal consumes. If the nutritional value is low, genetics will fail to some extent, and this failure will cause retarded growth in the bearded dragon.

3: Nutrition

Besides genetics, nutrition also plays a significant role in deciding an animal’s final height and growth. Different stages in the lifecycle of a beardie require different kinds of meals to sustain their growth. For a baby bearded dragon, highly proteinous food is required, and it gradually changes as it reaches different growth stages.

For every individual and their growth, nutrition is crucial. It acts as a building block of the body, helps fight against diseases, and acts as a strong shield to fight against any harmful impact.

4: Gender

Like humans, gender also makes the final height of a bearded dragon. Gender plays vital in determining the final height of a beardie. Male bearded dragons are tall and thick, while females are slightly slim and comparatively smaller than males.

It helps in judging whether a beardie is male or female. Such differences in appearance are sufficient to justify whether a beardie is a male or a female, as it is quite challenging to identify if it is a male or a female at first sight.
