How do I size wood plugs for the hole in my cabinet door?

Creating wood plugs to fix a hole in a wooden cabinet door is not an exact science. The easiest way to create a plug for your cabinet door is to measure the size of the hole you have and find the plug cutter that is closest to the hole size, but larger. You can use a regular ruler to measure the diameter of the hole in your door. Drill the hole in your door to the size of your plug cutter, and then create a plug in a separate piece of wood with a similar grain as the cabinet door.
