Bearded dragons are popular pets for many reasons, including their relatively easy care requirements and their friendly personalities.
However, before getting a bearded dragon, it’s important to know how big they get so you can provide them with the proper enclosure and diet.

Bearded Dragon Growth Stages
1. Newborns (1-2 months): Bearded dragons hatch from eggs at around 3-4 inches in size and weigh 4-6 grams. They’re tiny, fragile creatures during this stage.
2. Juvenile (3-4 months): At 3 months, they’ve grown to 8-11 inches long and weigh between 22-110 grams. Rapid growth is evident.
3. Sub-Adult (5-7 months): By month 5, they measure 11-16 inches and usually weigh between 102-115 grams.
4. Early Adulthood (8-10 months): They reach 11-18 inches in length and typically weigh 183-188 grams.
5. Late Adulthood (11-12 months): Bearded dragons are nearly fully grown, ranging from 13-24 inches in size and weighing between 350-465 grams.
6. Adult (12-18 months and beyond): Once they hit the one-year mark and beyond, their growth slows down.
Adult bearded dragons can measure anywhere from 16-22 inches and weigh between 380-510 grams.
As a rule of thumb, males grow larger than females.
Factors affecting bearded dragon size
There are a few factors that can affect how big a bearded dragon gets, including:
- Genetics: Some bearded dragon morphs, such as the German Giant, are known to be larger than others.
- Diet: Bearded dragons that are fed a healthy diet with plenty of insects and vegetables will tend to grow larger than those that are fed a low-quality diet.
- Lighting: Bearded dragons need exposure to UVB light to help them metabolize calcium and grow properly.
- Health: Bearded dragons that are healthy and free from parasites will tend to grow larger than those that are sick.
If you want to ensure your bearded dragon grows to a healthy size, there are a few things you can do:
- Feed your bearded dragon a high-quality diet that includes plenty of insects and vegetables.
- Provide your bearded dragon with access to UVB light for at least 12 hours per day.
