About this calculator
Species-specific starting ranges only. Temperatures depend on species, life stage, measurement location and setup; this short list is not a husbandry prescription. Use a thermostat on every heat source, measure the basking surface and cool area with suitable thermometers, and ask an exotics veterinarian or specialist guide about your animal.
Worked example
calculated with the default values below
Species group Bearded dragon Basking surface (°F) 100–108 °F · Warm area (°F) 90–95 °F · Cool area (°F) 72–79 °F · Night ambient (°F) 65–75 °F · Humidity (%) 30–40%
General background references
Disclaimer
These calculators offer general guidance and do not replace veterinary advice. Individual animals vary with breed, weight, health status and medication. Suspected poisoning from chocolate, medication, plants or chemicals is an emergency — contact your veterinarian or a pet poison control service immediately rather than relying on a calculator.
Implementation source
This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
Species care reference → basking, warm-side, cool-side, night and humidity ranges
- species
- selected reptile species
- temperature
- approximate target range in °F
- humidity
- approximate relative humidity range
These are husbandry starting references, not a thermostat setting for every enclosure. Measure actual basking surface and cool-side temperatures with suitable thermometers, use a thermostat, and follow a species-specific veterinary care guide.
Frequently asked questions
Why should I measure both warm and cool areas?
Reptiles need a thermal gradient so they can move between warmer and cooler areas. The listed ranges are starting references in °F and vary by species and measurement point. Use thermostats and measure the actual surface and ambient temperatures; consult a species-specific care guide or exotics veterinarian.
