Choosing Dining Room DesignOne of the biggest things to consider in dining room design are all the other functions that go on in the dining room. Is it a formal dining room that is only used for a couple of times a year? Does it double as a home office when people aren't around? Could the buffet double as a computer station? Selecting furnishings and materials has to do with the amount of traffic in it. What about the chandelier though? What kind of chandelier do you hang over a dining room table that is round, square, or oval?You should hang a round chandelier over a dining room table like that. If the dining room table is rectangular, you should hang a series of pendants or a long, linear chandelier. The chandelier should be 28-32 inches over the dining room table. The apron of the dining room table should be about 7 inches from the arm of the chair. There should be about 24 inches in between dining room chairs though. You don't want to bump elbows with your neighbor next to you. If you keep these tips in mind, you should have the best dining room of all your peers. Dining room design is a speciality of interior design, and it can quickly go sour if you don't have the specialists' tips at your use. First, consider the use of the dining room. Then, design it according to how people are actually going to use it.
