How many tables for a wedding
Guest tables = round up ((total people − people at the sweetheart or head table) ÷ seats per guest table). For 150 people, a sweetheart of 2, and 8-seat guest tables: 19 guest tables, 20 physical tables, 4 spare seats. This count has no room dimensions, table footprints, or aisle layout. It cannot say whether the tables fit the room.
Other headcounts, same formula
