While you may assume that bigger is better when shopping for a dining room table, you need to take the space into consideration. That gorgeous, extra wide table may look spectacular in the showroom but it will quickly dwarf a small room. Not to mention, you want your guests to be able to comfortably walk behind the chairs (not squeeze), even when they are occupied.
Most dining room tables measure around 30 inches tall with an average width of 36 to 42 inches. While that may not seem like a big difference, six inches can have a positive or negative effect on a room. Unless you absolutely have to, avoid tables that are narrower than 30 inches as things tend to get a little cramped if you have all of the seats filled.
Round or Square?
Although square tables tend to be preferred, if you do a lot of entertaining, round dining room tables are actually ideal because your guests can chat a little easier. Not to mention, since they sit on a pedestal, there are no legs to take up extra space. If you love the look of a traditional square table that seats four people but you know that on occasion you like to invite over an extra couple, consider buying one with a leaf that can be added and invest in two additional chairs that you can store in the spare room.
If you have a rug under your dining room table, it needs to measure at least four feet wider and longer than the table. This will allow room on all sides. No one enjoys sitting in a chair half on and half off of a rug.
Also, if you have a large chandelier, your dining room table needs to be 12 inches wider than the piece. This will balance the room and ensure that no one hits their head when they stand up.
