For a single-tier or two-tier wedding cake, a 10-inch to 12-inch diameter pedestal stand works for most sizes. For three tiers or more, use a stand rated for 30 pounds or above and confirm the base is at least 10 inches wide for stability. For cupcake towers or cake pop stands, choose by count: most 24-cupcake towers are 3 tiers at 8, 10, and 12 inches wide.
