Standard SMPTE 196M specifies:"Review room viewing conditions All observers in a review room shall be located within a standard observing area which shall be: a) within the limits of a 15-degree angle on either side of a perpendicular to the center of the screen, in both the horizontal and vertical planes; and b) at a distance of 3 picture heights +/- 1 picture height from the screen." Of course in a theatre, where you sit is a matter of personal preference. I personally prefer to sit rather close, usually on the centerline of the auditorium at about 2 screen heights. "Film Done Right" easily supports even closer viewing distances for 35mm prints, and large format 70mm films allow an "immersive" experience with prime seating often closer than 1 screen height. ------------------ John P.

I'm also a close sitter. In the smaller screens (all stadium) at my local i tend to sit on the 2nd or 3rd row. Just off center. Often in an empty auditorium i see people head to the back row. Or even worst, the extreme left or right of the back row seems a popular choice.
In the larger screens that have 3 or 4 rows of sloped seating at the front before the stadium seating, i sit on the 1st row of stadium seating.
If there are a lot of rows of sloped seating before the stadim seating begins, i sit on one of the back few rows of the sloped seating. These are my least preferable auditoria. I find that even the 1st row of stadium seating is too far from the screen. I find that the sloped seating is too vertically low down but i sit their anyway. On a couple of occasions i have found myself alone in an auditorium. I usually have a walk about. I noticed that the screen volume level can change noticably if you sit far back. Would sitting on the back row also affect how you would hear the surrounds? I think that some people dont understand that "the closer you sit the bigger the screen appears to be". They sit on the back row and complain that the screen is small in this auditorium

In a theater with common-width screens (most of the Cinemark 17 rooms here, all with stadium seating), I tend to sit closer for scope than I do for flat. In flat configuration, the added image height seems a little problematic to me (and of course the width is always the same). For scope I like to sit about 1/3 of the way back, no more than 1/2 if possible. For flat it's 1/2 to 2/3 of the way back. The screens here range from about 35 to 40 feet in width.For common-height screens (I think all of Regal Cinema World 8 rooms here are common-height, all with conventional seating), in the 2 flagship auditoriums I tend to sit no more than 1/3 from the front for scope, and closer for flat. The screens in these rooms are slightly smallish. Scope is about 34' wide, flat proportionately less. Their smaller rooms are a different story, since most of them have large screens and short-throws. I tend to sit near the back in them regardless of format. If I'm with other people who absolutely won't sit as close as I like to, I defer to their seating preference.
