Is there a site where i can put the dimensions of a room e.g. bedroom and suggest me a decoration for the room

Answer 1

Some things you just have to do for yourself. Room decor is a highly personal statement so to expect a generic web site to be able to do it is stretching things to quite a degree I would say.

Pick up a few home magazines and get ideas from them. Almost any issue is full of all kinds of examples for any room.
