The Wedding Seating Calculator estimates the number of tables and unused seats from guest count, seats per table, and optional buffer tables.
Formula
Base tables = ceiling(guests / seats per table). Total tables = base tables + buffer tables. Empty seats = total tables × seats per table − guests.
Example
For 95 guests at tables of 8, 12 tables are required, providing 96 seats and one empty seat before buffers.
Limitations
This is a capacity calculation. It does not create a seating chart or account for table shapes, accessibility, family groups, venue layout, vendors, or children.
