Where i usually start is measuring the hole size with calipers. Then I look up the drill size for that tap. Now I know the size and sometimes the thread. Finer threads will be larger than coarse threads of the same size. these will hardly ever be the same as what you measure with a caliper. Close is what you get.
The Dunning-Kruger effect is alive and well.
