  • Cake and gift table: add about 40 sq ft

What changes at 25 guests

An intimate group like this fits in a house, a private dining room or a small venue. With only 4 tables, one delivery and a two-person crew can usually set the room quickly, and a statement chair style is affordable because the total quantity is small.

Planning a birthday party

Birthday parties rarely need a seat for everyone at once. Mix a few dining tables with lounge-style chairs so guests can circulate.

Milestone birthdays (30, 40, 50) often borrow wedding-style decor on a smaller scale. A statement chair is an easy way to make the room feel special.

For backyard or rooftop parties, choose chairs that tolerate sun and uneven ground.

Mistakes to avoid

  • Over-ordering for a mingling event.
  • Skipping a comfortable chair for the guest of honor.
  • Forgetting kids' seating at family parties.
