In the novels, Amelia is the same age as Lina. In the anime, she is believed to be one year younger. This would make her 15 when the novels started, and 14 when the anime started. In Slayers NEXT, she would be 15, in Slayers TRY she would be 16 and in Slayers Revolution and Slayers Evolution-R, 17 years old. Her height is said to be 155cm (5'1"), although it is not clear on which point of the story this measurement is based on. (Other characters have commented on her getting taller throughout the series.)
