The number of people that can typically be seated at a seminar table depends on several factors, including the size and shape of the table, the seating arrangement, and the space available in the seminar room. 
1. **Table Size and Shape**: 
   - **Rectangular Tables**: A standard rectangular seminar table, often measuring around 6 to 8 feet in length, can usually accommodate 6 to 8 people. This assumes seating on both longer sides and possibly one person at each end.
   - **Round Tables**: A round table with a diameter of about 5 feet can typically seat 6 to 8 people comfortably.
   - **Square Tables**: A square table, often used in smaller settings, might seat 4 people, one on each side.
2. **Seating Arrangement**:
   - **Classroom Style**: In a classroom setup, tables are arranged in rows facing the front, and each table might seat 2 to 4 people, depending on its length.
   - **U-Shape or Horseshoe**: This arrangement allows for more interaction and visibility, typically seating 10 to 20 people, depending on the room size and table configuration.
   - **Boardroom Style**: A large, single table setup, often rectangular or oval, can seat anywhere from 10 to 20 people, depending on the table's dimensions.
3. **Space and Comfort**:
   - Adequate space between chairs is crucial for comfort and accessibility. Typically, 24 to 30 inches of table space per person is recommended.
   - The room's overall size and layout will also dictate how many tables and chairs can be accommodated without overcrowding.
In summary, while a standard seminar table might seat 6 to 8 people, the actual number can vary based on the factors mentioned above.
