Short Answer 1: It depends on the scoop. Short Answer 2: It doesn't matter. Consistency matters a lot for a good cup of coffee, but you can adjust number of scoops used per whatever scoop you like to use. So the actual size of the scoop matters less than using a consistent number of scoops once you figure out your sweet spot. How big are the coffee scoops that I make? It varies. I don't use templates and my process isn't automated. Each scoop is made by hand and eye. It tends to average out to around 2 tablespoons, but it can vary from scoop to scoop.
