all beardies are different. it just depends on their body type just liek people. some people are fat, and some are skinny. some are tall, others are short. same goes for a lot of animals and beardies are a good example. I have 4 beardies right now and they range from 16" and 315g to 19" 455g. But then i have one huge female that is close to 18" and 520g. So it just depends on their body type. From my experience, as long as they have their fat deposits built up which is best seen when the area around their tail is built up and not sunken in with divits or bumps to where you can see their hips, then they should be at a healthy weight. hope that helps!
