Standard collet body...3 - 4 times the tungsten diameter. Gas lens collet body...6 - 8 times the tungsten diameter.
Another way to look at is that with a gas lens collet body you can extend the tungsten the same distance as the inside diamter as your gas cup.

Thanks Ernie. I use gas cups at your suggestion and couldn't remember the correct distance.
