The hole size for the soap dispenser is 1 1/16". The holes size for the spout is 1 3/8". There really isn't a recommended distance from the holes to the edge of the sink. It depends on how much space you have to work with and how big the sink is. Please keep in mind that the reach of the spout is 9 5/16".
