Steve's original design was much geekier and gawky and he was voiced by Ricky Blitt. Halfway through production, Grimes replaced Blitt and Steve's design was made to be more attractive, so he would be less comparable to Neil Goldman from Family Guy. Steve Smith is the baby of the family, Stan and Francine's high-school aged son. Steve is 85 pounds (39 kg) and around 4 ft 8 in (142 cm) which is really short even for his age.
Steve is portrayed as an enthusiastic, ambitious, and wimpy nerd. Steve was 13 years old at the beginning of the show and is now 14 (technically should be 15 by timeline), placing Steve's year of birth around 1992, as the show first aired in 2005. In the official series, he is not presented as nerdy as he is in the show's unaired precursory pilot when his appearance, voice and manner greatly contrasted from what they would eventually become. In the precursory pilot, Steve was also gawkier, scrawnier and voiced by Ricky Blitt (as opposed to Scott Grimes). In the official series, he's become emphasized as soft, emotional, cute and endearing. As part of his emotional and sensitive character, Steve is combined with a screechy wail.
