Most decorating themes are dependent on the size and shape of the room and what it is going to be used for. Living room decorating ideas are no different in that the type of decor chosen is going to be largely dependent upon the room's size and how that room features in the overall utility of the house generally. Some people's living rooms remain completely empty for much of the day and are only used during the evening when the family is at home. Other living rooms are in use constantly with a continuous procession of small children and pet animals surging through the place. It is totally inappropriate to decorate the first kind of living room in the same way as the second kind: the adults would not appreciate small children and muddy pups clambering over an off-white three-piece suite and a home where adults live wouldn't really appreciate living in a room categorized as nursery-orientated. As with anything else, utility is the prime decider when it comes to decor - and that includes living room decorating ideas.
