How much water to use in making a yeast dough can depend on your altitude. At higher altitudes (above 4000 ft), flour takes more water, usually 2 or 3 tablespoons more than what the recipe calls for. It can also depend on the type of flour you are using. Without specifics from a recipe, you may simply have to experiment. When I make a yeast-raised pizza dough, I use about 3/4 cup of warm water to 2 cups of unbleached white flour.
