A 3″ dial face is a fairly large size, they are about the size of a fist. Most BBQ thermometers are made this way so that they can be read easily from a distance.

These thermometers mount using the 1/2″ NPT threading on the back. NPT is a pipe thread that requires a 7/8″ hole to mount into. Most smokers on the market already have the hole in the door that is covered with a cap. Some of the higher end units are already threaded to fit this type of thermometer.
