Capacities vary widely. Small tasting bowls are often 2–12 ounces, some disposable bowls are about 34 oz, and larger chip-and-dip pieces can be much bigger (examples include a 4-gallon chip-and-dip bowl).
Common shapes include round, oval, and square. Specialty items and tortilla-forming supports may also appear in round or triangular shapes for creating tortilla bowls.
Look for dedicated small guacamole or dip bowls, chip-and-dip designs with a central dip well, and novelty shapes (for example, avocado-shaped bowls) that may include lids and spoons for tidier presentation.
