Minimum Iguana Enclosure Dimensions

By Melissa Kaplan, William K. Hayes

Part of Iguanas For Dummies Cheat Sheet

Don’t make the mistake of starting with an iguana enclosure that’s too small – iguanas grow quickly. The following table shows you the minimum enclosure dimensions needed based on the average size in snout-vent length (SVL) and snout-tail length (STL) for the first seven years. So, unless your iguana is full grown, when its STL is more than two-thirds the enclosure width, it’s time for a new enclosure.

SVL (in inches)) STL (in inches) Minimum Dimensions (in feet)
2.5–7 9–18 3 x 1 x 1.5
8–10 20–28 3.5 x 1 x 2.3
11–12 28–36 4.5 x 1.5 x 3
12–14 30–42 5.25 x 1.75 x 3.5
14–16 35–54 6.75 x 2.25 x 4.5
18–20 45–60 7.5 x 2.5 x 5
20–22 50–66 8.25 x 2.75 x 5.5
20–24 50–72 9 x 3 x 6
