Final answer:
Tablecloths should overhang the table edge by either 6 inches or 8 inches, depending on the shape of the table.
Step-by-step explanation:
In order to determine how many inches a tablecloth should overhang the table edge, it is important to consider the size and shape of the table. A general rule of thumb is to have a 6-inch overhang, which provides enough coverage while still allowing the tablecloth to stay in place. However, for rectangular tables, a 8-inch overhang is often preferred to ensure the entire table is fully covered.
