Default master cylinder size?

Hey i need a little help. I am changing my master cylinder and not sure of the bore size. My options are 9/16 and 5/8. I tried to measure but I am not exactly sure how the measure. If it helps I used a 7/16 to take the banjo bolt out.

Single disk uses the smaller bore.

It says that the dual disc has a 11/16 and mine is either a 9/16 or 5/8. I tried to measure but nothing looks right to me.
