Question for the mathematically oriented (archery)!

[Virilis]

I remember a roman historian (Vegetius?) requiring a soldier to hit with an arrow a human size target from 100 metres / yards. So here is the problem:

-What size of a rectangular target would a human make (yes, I shoot cardboard boxes :wink: )? Something like a surface of 50cm x 70cm perhaps?

-How about the distances? If I am shooting for example from a distance of 30 metres what size of rectangular box would represent this size of a "human target"? Is there perhaps a pattern to calculate the size of a target to use with different distances?

I hope you understood what I mean and thanx in advance :wink: !
