Does anyone know how JKR picked the wand length in relation to the wizard/witch's height? I think I remember a mathematical equation, but I can't remember it.

I don't believe there is a mathematical equation, since JK admits that maths are not her strong point. I think the general rule of thumb was that the taller the wizard/ witch, the longer the wand. - Cavalier One^{(Wizarding Wireless Network)} 15:37, 12 December 2007 (UTC)
