Carefully drill the head off and then measure the diameter of the hole.
Drill bits make a very handy diameter gauge to figure out the size of a small round hole.
As to the length, that can vary depending on what the accumulated thicknesses of materials it is fastening together. You can make a little tool to check that. Take a piece of stiff wire and bend a tiny L shape into one end of it. Then poke that into the hole and pull back until the L hits the inside surface of the stack of materials. Put some masking tape or a mark of some type around the wire on the outside right against the surface. The distance between the inside of the L and the mark from the outside is the "grip length" you need. The package of pop rivets will state what the grip range for the contents is.
