What is a common size for a standard cocktail glass?

The correct choice is based on the typical capacity of standard cocktail glasses, which usually range between 4 to 6 ounces. This size is ideal for serving classic cocktails, allowing enough space for the drink while providing room for garnishes and ice, if applicable. Common cocktail glasses include the martini and coupe glasses, both designed to enhance the drinking experience by showcasing the drink's appearance and facilitating the enjoyment of its aromas.

Options outside this range either represent sizes that are too small, limiting the drink volume and presentation, or too large, which can dilute the drink experience and lead to an unbalanced serving. The 4 to 6-ounce range strikes the right balance for most cocktails, aligning with conventional standards used in the bartending industry.
