A reptile enclosure needs a hot basking spot and a genuinely cooler side so the animal can regulate its own body temperature. Enter the basking and cool side ranges from the care reference you are using along with your actual readings, and this tool shows whether each zone sits inside the range, how far outside it is and the gradient between the two.
This tool does not publish recommended temperatures. Basking and cool side figures differ completely between species and ages, no body publishes a table covering all of them, and a wrong temperature harms the animal immediately. So there is no species list here: the figures from your reference go in and the tool only compares. Judgments include the end values, so a reading exactly on the limit counts as inside (as of October 2026).
The same enclosure reads very differently depending on the spot and the instrument you use, whether a surface thermometer, an infrared gun or a probe, so only consistent measurement makes the comparison meaningful. This tool is for reference only and does not replace veterinary care. Contact a veterinarian who treats reptiles right away if your animal gapes and breathes hard or refuses to bask and stays hidden.
Frequently Asked Questions
No. Figures differ completely by species and age and a wrong one harms the animal, so enter the range from your care reference or your veterinarian and let the tool compare.
This tool does not judge method. Read the basking surface where the animal rests and the cool side at floor level, the same way every time, and the comparison stays consistent.
A reading equal to the low or high end from your reference counts as inside the range, and the results say the ends are included.
