Reptile Habitat Calculator

How It Works

Reptiles are ectotherms — they regulate body temperature by moving between warm and cool zones, so a proper temperature gradient is essential. The basking spot should be the hottest area, with the cool side 10-25°F lower. UVB lighting is critical for species like bearded dragons that need it to synthesize vitamin D3 and metabolize calcium; without it, they develop metabolic bone disease. Humidity requirements vary dramatically: desert species (leopard geckos) need 30-40% while tropical species (crested geckos) need 60-80%. Never house multiple reptiles together unless the species is specifically social — most are solitary and will stress each other.
