Die size question?

I am turning a piece of 16mm stainless bar down to put a 12mm thread on the end using a 12mm die, am I right in saying I need to turn it down to 12mm or do I need it a bit chunkier? I have tapped lots of holes before but funnily enough I have never needed to use a die hence the question!
