Kids Birthday Party FAQs

How much should I spend on a kids birthday party?

The average kids birthday party costs $200-$400 in 2026. Budget parties can be done for under $150 with DIY decorations and homemade food. Premium venue parties (trampoline parks, etc.) run $400-$800+ including venue fees.

How many guests should I invite to a kids party?

A common rule is 'age plus one' (e.g., 6 guests for a 5-year-old). For toddlers, 4-6 guests is manageable. For school-age kids, 8-12 guests creates good energy without chaos. Always invite a few extra since some will decline.

What time should a kids birthday party start?

Mid-afternoon (2-4 PM) works best for most ages. Toddler parties work well at 10-11 AM when energy is high. Avoid meal times unless you're serving a full meal, and end before bedtime routines start.

How long should a kids birthday party last?

Plan for 2 hours for ages 1-4 and 2-3 hours for ages 5-12. Younger children tire quickly, while older kids can handle longer celebrations. Always have a clear end time on invitations.

What's the best birthday party theme for a 5 year old?

Popular themes for 5-year-olds in 2026 include dinosaurs, unicorns, superheroes, Paw Patrol, princesses, and Frozen. Choose based on your child's current interests — themes they're obsessed with make the most memorable parties.
