Bead Cap Sizing
Not sure what size bead cap you need? It really depends on what you expect out of your bead cap. Oftentimes, the bead cap is used to "dress up" a bead, crystal, stone, or other type of bead. It adds a touch of elegance as well. If this is the effect you are looking for, you can choose a bead cap that's a little smaller than your bead.
In the case where you may be trying to cover up part of your bead due to an imperfection, such as a chip near the hole, you would need to choose a bead cap that is larger than your bead.
There is no rule of thumb—it's really just a matter of preference and desired outcome.
