Visualizing Lizard Age vs. Human Years
The chart below helps you compare your lizard’s age to its human age equivalent. Since lizards mature rapidly in their first year, the line graph highlights how their early development corresponds to humans. Use this chart to plan age-appropriate care.
How to Calculate Lizard Age in Human Years
The general formula:
Human Age = First Year Value + (Lizard Age - 1) × Annual Increment
For example, a 4-year-old Leopard Gecko:
- First year = 18 human years
- 3 additional years × 2.5 = 7.5
- Total = 25.5 human years
