What are the sizes of dining tables?

The standard width of a kitchen table is 1 meter or 100 centimeters.
The length of the dining table is 2.0 meters, 2.2 meters, 2.4 meters, 2.6 meters, 2.8 meters, and 3.0 meters. The longest dining table at home can exceed 3 meters, but such a dining table is custom-made, and dining tables longer than 3 meters are not available in stores.
The most popular sizes for buying dining tables of this length are from 2.4 to 3 meters. But if the kitchen space is small, then buyers will choose a 2-meter-long dining table.
