If there is an existing small dining table in a home, it is possible to get another table to accommodate more people. If a homeowner does not want to buy such a large dining table for the home, an option is to get a smaller table that has leaves. To accommodate more people, the leaves can be added to the table. Until the leaves are needed, they can be stored.
The table size should provide enough room for place setting. The usual width distance needed for a place setting is approximately 24 inches.
