To determine the right size deadbolt, measure the thickness of your door (most standard doors are 1-3/8" or 1-3/4" thick) and the backset, which is the distance from the edge of the door to the center of the hole (usually 2-3/8" or 2-3/4"). Choose a deadbolt that matches these measurements for proper fit and security.
