What kind of waffles are you making?
Some of the true Belgian waffle (the rich dense version you get from a street vendor in the Grand Plaza) recipes have a soft dough instead of a batter. My favourite recipe uses a dough which cooks wonderfully in an old fashioned belgian waffle maker but doesn't do well in a standard waffle maker.
If so, it depends on your presentation preferences. Use a walnut sized piece of dough for buffets or desserts, or a clementine sized piece of dough for the traditional single Belgian waffle maker.
Hope this helps-
