Adult Size Chart — Popular Snakes & Lizards

Typical adult lengths for commonly kept species. Ranges vary by sex, genetics, and quality of care — use these as general guidelines, not guarantees.

📏 Why size matters: Knowing your animal's adult size before you buy is essential for planning the right enclosure. A species that seems manageable as a juvenile can require a very different setup — and a very different level of experience — at full size.
