The standard size for a salad bowl is about 12” in diameter. A bowl this size typically serves 3-4 people. If you’re just looking for you and your partner, a 10” bowl would do nicely, and it would take up less space on the table. If you’re looking for something for larger gatherings and events, you can find bowls as big as 15” (serves 6-8), 17” (serves 10-12), or even 20” (serves up to 18).
