A bigger ceiling fan is not necessarily better. It is important to choose a fan that is the correct size for the space. A fan that is too small will not be effective, and a fan that is too big will waste energy. When choosing a ceiling fan, it is important to consider the height of the ceiling and the size of the room. The fan should be at least seven feet above the floor and should have blades that are at least six inches shorter than the width of the room.
