Leopard gecko care guide

Eublepharis macularius

A ground-dwelling, crepuscular gecko from arid grassland. The old 10-gallon recommendation is obsolete — they need floor space, a real gradient and enrichment.

Leopard gecko enclosure size

Terrestrial — floor space first. An adult leopard gecko should live in at least 36" L × 18" W × 18" H; we build toward 48" L × 24" W × 18" H (4 × 2 × 1.5 ft, roughly 8 sq ft of floor and about a 90-gallon glass equivalent).

Hatchling / baby
24" L × 18" W × 12" H recommended · min 20" L × 12" W × 12" H
Juvenile
36" L × 18" W × 18" H recommended · min 24" L × 18" W × 12" H
Adult
48" L × 24" W × 18" H recommended · min 36" L × 18" W × 18" H

Temperature and heating

Overhead halogen creating a warm surface, on a dimming thermostat. Heat mats alone don't warm the body properly.

Basking / warm surface
94–97°F surface on the warm end
Warm side (ambient)
85–90°F ambient
Cool side (ambient)
70–77°F ambient
Night
67–74°F

Lighting and UVB

UVB: T5 UVB 5–6% over the warm end (UVI 2–3 at basking). Run lights on a 12–14 hours photoperiod, on a timer, and replace UVB bulbs on the manufacturer's schedule even while they still emit visible light.

Humidity

Target 30–40% ambient. Dry overall with a permanently moist humid hide.

Substrate and depth

Topsoil / play sand mix (no loose calcium sand). Depth: 3–4 in.

Enclosure tips and furnishing

  • Three hides: warm, cool and humid
  • Rocks and low climbing structures
  • Shallow water dish
  • Clutter and sight breaks

Build list

  • 36–48in front-opening enclosure — Space for a genuine warm-to-cool gradient.
  • Halogen basking bulb + T5 UVB — Surface heat plus UVB is the current standard of care.
  • Digital thermostat — Every heat source must run through a thermostat — unregulated heat burns animals.
  • Two digital probe thermometers + hygrometer — Read the warm side, cool side and humidity directly — stick-on dials are inaccurate.
  • Topsoil/sand substrate mix — Diggable, dust-free, and safe versus calcium sand.
  • Three hides + moss for the humid hide — Shedding problems trace straight back to a missing humid hide.

Leopard gecko FAQ

How big should an adult Leopard gecko enclosure be?

At least 36" L × 18" W × 18" H, and we recommend building to 48" L × 24" W × 18" H — about 4 × 2 × 1.5 ft, or a 90-gallon glass equivalent. Terrestrial — floor space first.

What temperatures does a Leopard gecko need?

Basking or warm surface 94–97°F surface on the warm end, warm side 85–90°F ambient, cool side 70–77°F ambient, night 67–74°F. Overhead halogen creating a warm surface, on a dimming thermostat. Heat mats alone don't warm the body properly.

Does a Leopard gecko need UVB?

T5 UVB 5–6% over the warm end (UVI 2–3 at basking). Photoperiod: 12–14 hours.

What humidity does a Leopard gecko need?

30–40% ambient. Dry overall with a permanently moist humid hide.

What substrate is best for a Leopard gecko?

Topsoil / play sand mix (no loose calcium sand), at a depth of 3–4 in.

How big does a Leopard gecko enclosure need to be for a hatchling?

Hatchling / baby: 24" L × 18" W × 12" H recommended, minimum 20" L × 12" W × 12" H. Scale up to the adult footprint as the animal grows.

How often should I clean leopard gecko enclosures?

Spot-clean daily and deep clean on a schedule that depends on your substrate. Get a cleaning schedule.
