Selecting Point Diameters

[Leo L.]

I'm looking to fill my inventory with a selection of field points so I can be ready to tune any arrow to any bow.  While looking at several places online to buy them I found they're offered in different diameter sizes. I knew this but I wasn't prepared for it.

Question is, how do I know what diameter I'll need according to arrow size?  Is there a chart somewhere that will help?

9/32" (18/64")
5/16" (20/64")
21/64"
11/32"(22/64")

For woods you buy them to match the shaft diameter.  Most carbons use a 5/16" point.  Aluminums are sized with the first two digits being the OD.  A 2016 is 20/64 in outside diameter or 5/16.  The newer aluminums are different, and you may need to refer to a spec sheet.

Thanks AP!
