The thing about "Shirou is 20cms smaller than Archer because of Avalon" is bullshit.
Kirei is a grown-up man but after 10 years he is 10cm taller. Wtf?
Simply, using magic improves your body in many ways.
Avalon does also hide your being tanned? No, Archer's skin is a result of his intense usage of magic. In those years Shirou abused his magic and his body changed dramatically.
