How big a vivarium does a bearded dragon need? Measure your setup

A bearded dragon warms up by walking to a hot spot and cools down by walking away, so the length of its viv matters more than most people think.

Type in your dragon's length and your viv's measurements and get a green, yellow or red check on length, depth, height and lamp distance. The RSPCA's adult minimum is 120 x 60 x 60 cm. Always ask a reptile vet about health worries.
