Bearded Dragon vs Leopard Gecko: Which Should You Get?
| Enclosure size | Beardie: 4ft+ | Leo: 20-gal long |
| UVB | Beardie: mandatory | Leo: traditionally optional |
| Diet | Beardie: omnivore | Leo: strict insectivore |
Space and setup
Bearded dragons need a minimum 4ft x 2ft x 2ft enclosure as adults; leopard geckos are comfortable in a 20-gallon long. Bearded dragons also require UVB as close to mandatory husbandry, where leopard geckos have traditionally been kept without it, though low-level UVB is increasingly recommended for them too.
Diet complexity
A bearded dragon's diet is meaningfully more involved — daily fresh produce alongside insects, with the ratio flipping as they age. Leopard geckos are strict insectivores with a simpler, more consistent feeding routine throughout life.
Temperament and handling
Both are generally considered docile and tolerate handling reasonably well once settled, though bearded dragons are more visibly active and interactive during the day, while leopard geckos are more secretive and nocturnal/crepuscular.
Which suits a first-timer better
Leopard geckos are generally the easier, lower-cost first reptile given the simpler diet and smaller footprint. Bearded dragons make excellent pets too, but the larger enclosure, mandatory UVB, and more complex diet mean slightly more upfront cost and ongoing effort.

A single adult bearded dragon needs a minimum 4ft x 2ft x 2ft enclosure, with 6ft x 2ft x 2ft increasingly recommended as best practice — plus a linear T5 HO UVB tube, an overhead basking bulb on a thermostat, a real thermal gradient, a sturdy basking platform, and a shallow water dish.
A complete bearded dragon setup needs a 4ft+ enclosure, a linear T5 HO UVB tube, an overhead basking bulb on a thermostat, two thermometers, a basking platform, a hide, a shallow water dish, and age-appropriate substrate — all running and stable for at least 48 hours before the dragon arrives.
Hatchlings can start in a 20-gallon long tub, juveniles need to move to roughly a 40-gallon breeder footprint by a few months old, and adults need a minimum 4ft x 2ft x 2ft enclosure, with 6ft x 2ft x 2ft recommended.
Basking surface temperature should run 95–110°F depending on age (hotter for hatchlings, cooler for adults), with a cool side around 75–85°F, all provided by an overhead basking bulb on a thermostat — not a heat mat or heat rock.
Bearded dragons need a linear T5 HO UVB tube at 10.0 or 12% output, running the length of the basking third of the enclosure with nothing between bulb and dragon, replaced every 6–12 months regardless of whether it still produces visible light.
Bearded dragons should be kept at roughly 30–40% ambient humidity. Sustained humidity above 50% significantly raises the risk of respiratory infection in this dry-climate species — brief daily misting or a shallow soak handles hydration and shedding needs without pushing ambient humidity up long-term.
