Kids birthday parties for ages 1-12 typically cost $150-$400 and work best with 8-20 guests for a 2-hour party. The top themes by age group: toddlers (1-3) love sensory themes like bubbles, farm animals, and rainbow parties. Preschoolers (4-5) gravitate toward character themes — dinosaurs, princesses, and superheroes. Elementary kids (6-9) prefer interactive themes like science experiments, Minecraft, and sports tournaments. Pre-teens (10-12) want social experiences: slumber parties, escape rooms, and cooking competitions. Plan 10-15 minutes per activity for kids under 6, and 20-25 minutes for ages 7-12. Every kids party needs a structured flow: 15 min arrival + free play, 20-30 min organized games, 15 min food, 10 min cake, 15-20 min free play, 10 min goodbyes. Food rule of thumb: kids eat 60% of adult portions. Order 1.5 slices of pizza per child (not 2-3 like adults). Budget for 20% more supplies than your guest count — plates get dropped and cups get lost. Where the money goes is remarkably consistent whatever you spend: food and drinks take about a third of a kids party budget, and favors, cake and activities each take another sixth.
