Tables
You need two types: seating tables for guests and utility tables for food, drinks, cake, and gifts.
Seating tables (6-foot banquet tables seat 6–8 guests):
- 50 guests open house → 6 seating tables
- 75 guests open house → 10 seating tables
- 100 guests open house → 12 seating tables
Utility tables — add these on top of your seating count:
- 1–2 tables for food and drinks
- 1 table for cake and desserts
- 1 table for gifts and cards
Don't underestimate the utility tables. A full graduation party spread needs more surface area than most families plan for.
Extra Tables for the Buffet Line
If you're doing a self-serve buffet, one table is almost never enough. Two 8-foot tables end to end gives guests room to move through the line without everyone piling up at the same spot.
A Signing Table
Many graduation parties include a signing board, memory book, or display of photos. That needs a dedicated table — not a corner of the gift table, its own space where guests will actually stop and use it.
