You want to buy a new dining table and there's the question of the ideal dimensions to show up quickly. The dimensions are determined by the size of the Room, where the table to stand. You should be able to go in the ideal case, still on the table, even if people are sitting in it, except if you want to put the table into a corner with corner bench.

It has enough space and is not limited by the size of the Room, so you should ask yourself, how many people are regularly eat at the table, and for how many persons you want to easily have space, if you load guests.

Per Person, you should expect a minimum of 60 cm space requirement. You want to prefer to really comfortable and a little more luxurious, so you can expect 70 to 80 centimeters per Person. You want to place on the short sides (ends), also a Person, so you can expect additional 40 centimeters per page.
