The size of a table in a barbecue plaza is not a fixed value; it can be determined by the number of people to be accommodated and the design of the table. Generally speaking, tables in BBQ plazas are usually rectangular or round shaped to make it easier for more than one person to dine at the same time.

Usually, the size of a rectangular table can be determined based on the maximum number of people to be accommodated at each table. Typically, a rectangular table can accommodate 4-8 people for dining. The size of the table may be customized as needed, usually in a few feet or meters. For example, a 6-foot rectangular table can accommodate 6-8 people for dining.

As for the size of round tables, they are usually measured by diameter. A common round table is one meter in diameter and can accommodate 4-6 people for a meal. If a larger capacity is needed, the diameter can be increased accordingly.

The size of a table in a barbecue plaza therefore depends on the design and needs of the barbecue plaza, and there is no single standard size.
