How to set up a home for a leopard gecko
Most problems new owners hit with a leopard gecko trace back to the setup, not the animal. Get the space, the temperature and the hiding places right before the animal comes home, and the rest of the care gets dramatically easier.
What a leopard gecko actually needs from its enclosure
- A 20 gallon long is the accepted minimum for one adult; a 40 gallon breeder gives a much better temperature gradient.
- Three hides are the standard: warm, cool, and a humid hide in the middle kept damp with moss or paper towel for shedding.
- Heat from below (heat mat on a thermostat) works well because this species absorbs warmth through its belly.
- Avoid loose sand — impaction risk. Paper towel, tile or a compacted soil/clay mix is safer.
Environment target: Warm side 88–92°F (31–33°C), cool side 75–80°F (24–27°C); humidity 30–40% ambient, 70–80% inside the humid hide; Low-level UVB beneficial; no bright lighting needed.
Set it up in this order
- Choose the space. Big enough for the adult animal, not the one you bring home — leopard geckos grow faster than most people expect.
- Get the environment stable. Heat, UVB and ventilation and a clear day/night cycle, all measured with real equipment rather than guessed.
- Add cover and hiding places. An animal with nowhere to hide is a stressed animal, even in a large enclosure.
- Add the essentials. Food, water and the specific items from the checklist below.
- Run it empty for a day or two. Verify your numbers before the animal arrives — this is the step people skip and later regret.
Setup checklist
- 20 gallon long (or larger) enclosure
- Thermostat-controlled heat mat
- Three hides including a humid hide
- Digital thermometers at both ends
- Safe substrate (tile, paper towel, or soil/clay mix)
- Shallow water dish
- Calcium powder and a feeder insect tub
The setup mistakes that cause most problems
- Buying for the baby. Size the enclosure for the adult.
- Skipping the measurement tools. A thermometer you don't have is a guess you can't check.
- No cover. Open, bare space reads as exposure to a prey animal.
- Placing it badly. Drafts, direct sun, high-traffic doors and kitchens with fumes are all poor spots.
Related questions
Do leopard geckos need UVB?
They can survive without it if you dust food with D3, but low-level UVB is increasingly recommended and improves activity and appetite. If you use it, keep it low-output — this is a shade-dwelling species.
How often should I feed an adult leopard gecko?
Two to three times a week, offering as many correctly sized insects as it eats in 10–15 minutes. Feed in the evening.
Why is my leopard gecko not shedding properly?
Most often the humid hide has dried out or the humidity is too low. Keep a damp hide available at all times rather than only when you notice a shed starting.
