What size drill bit to use for wall mount?

To get the right-size hole, measure the shank of the drill bit against the front of the anchor -- its diameter should be the same size or 1/16 inch more than that to make the opening for the screw. If the diameter of the anchor is displayed on the packaging, drill the hole with a bit of the same diameter.

How can you tell if a drill bit is for masonry or wood?
