To choose the right size of drill bit, you’ll need to know what size screw, and therefore rawl plug, you’re going to use. If you buy a set of drill bits of varying sizes, you should be able to hold them up to your rawl plug to get an estimate of the size. You’ll need to use a drill bit at least as large as your rawl plug, or else you won’t be able to insert it into the wall.
