Size of Auditoriums

The most important thing in the design of the Auditorium is sizing to facilitate Audience and performers avoiding all possible problems.

1- Size of sitting area in Curvy rows

The seating capacity for 1 person should be 6 Sft to 7 Sft which includes a minimum passage area of 5 Sft for 1 person.

2- Size of sitting area in Straight rows

The seating capacity for 1 person should be 6 Sft to 7 Sft and the minimum area of    5 Sft for a person should be added for passages.

3- Volume Capacity for 1 Person and Height of Auditorium.

volume required for each person in the auditorium should be 124 Cft to 160 Cft with a minimum height of 20 Feet and Maximum Height can be calculated using nominal volume and area required for one Individual.

 4- Seating Alignment.

Seating alignment should be staggered in a way so that spectator in any line is not sighting over the head of an individual sitting in front of him.

5- Head Room

Minimum head rooms under the landings and cantilever portions should not be less than 7 ft.

The position of the screen should be fitted in a way that the angle eyesight of the person sitting in a front line from the top of the screen may not be more than 34 degrees.
