Best enclosure size for an adult crested gecko

For a single adult crested gecko, you’ll want a space that’s at least 18 inches long, 18 inches wide, and 24 inches tall.

This is the minimum size they should have.

Why Does Size Matter?

  • Arboreal: Crested geckos primarily live in trees. They need vertical space to climb, jump, and explore.
  • Activity: A larger enclosure allows your gecko to exercise, keeping them healthy and stimulated.
  • Enrichment: More space means more room for hides, plants (live or fake), branches, and decorations which provide enrichment and security.

However, bigger is always better.

If you have the space, consider an enclosure 18″ x 18″ x 36″. This will provide increased room for activity and environmental complexity.

Popular brands like Exo Terra and Zoo Med offer great terrariums.

You can also look into custom options if you want something special.

Hope this helps…
