Emily Post's website offers place setting rules for the dinner table. The Table Settings Guide page has links to instructions and illustrations for basic, formal and informal place settings.
The basic place setting has a plate, glass, napkin, fork, knife and spoon. A bread plate and butter knife remain optional. The informal setting calls for an additional salad fork and soup spoon. A drinking glass for water, wine, juice or iced tea is often added. Other optional pieces include a salad plate, desert spoon and fork, and coffee cup and saucer.
The formal place setting calls for additional pieces of silverware, such as a fish fork, fish knife, salad knife, fruit spoon and oyster fork. Several glasses are typically required, including those for water, red or white wine, and sherry or champagne. A service plate, or charger, remains on the table under all plates that precede the entrée.
