These terms are commonly used in architectural manuals. The seating arrangement of an auditorium follows specific spacing, size and exit ways. A multiple-aisle seating arrangement of auditorium has 14-16 chairs in a row. The exit ways are at both ends of the row. It will have only one 7-8 chairs if it has one exit way.
A continental seating arrangement of an auditorium has a central section. The limit for chairs in a row exceeds in comparison to multiple-aisle arrangement. It has wider spacing, aisles and exit doors are also located strategically. A continental seating arrangement can accommodate more chairs if planned carefully.

Seat widths in an auditorium seating
The comfort of the spectators’ seating depends solely on the width of the chair. The general spacing ranges from 18 to 24. However, in some cases the sizing may even fall out of the specified range. Seat widths are important while planning the layout as it helps to estimate the potential number of seats that can be accommodated in the available space.
