Most electrician use the height of an electrician's hammer to mark the bottom of an outlet box. That height is 18 inches.
I believe it to be about 12 inches at the minimum.
For a light switch in the home four foot to centre is a reasonable height. Some contractors set the outlet box at four foot to the bottom of the outlet box and other contractors set the box to four foot to the top of the outlet box. There is no code rule that stipulates the exact height that the outlet box must be set to.
There are no standard heights required for outside receptacles. Usually they are in accordance with the equipment that they are to supply voltage for. In areas that receive a high snow level they are positioned at a height so as to be accessible year round.
