Hatchlings are roughly 1 inch (2.5 cm) in length. After the first year, a hatchling, now referred to as a yearling, should be around 2-3.5" inches long. Male yearlings become sexually mature around 4 inches in length, females about 5 inches. The average length of an adult RES can vary between 7 to 12 inches. Adult males range between 7-9 inches (17.8 cm - 22.8 cm) while adult females fall between 10-12 inches (25 cm - 30.5 cm).Note: Size cannot reliably indicate age; however, captive turtles usually grow at a much faster rate. This is usually a result of overfeeding and a lack of hibernation periods. Overfeeding causes dangerous health (physical and intestinal) issues and captive RES do not need hibernation.
