Sightlines can be solved in a complex equation:

       D (N+R)
 C = -----------  - R
         D+T

where:

C = the 'C' value

D = the horizontal distance from the spectator's eye to the focal point on the field

N = the riser height

R = the vertical height of the point of focus

T = the seating row depth

Sightlines: Before & After

See the slides above illustrating what adding tiered seating to an event can do for the spectator.

We know event sightlines.

SGA takes sightlines seriously, and computes the values of each seat where necessary to ensure that even in the back row the view is unobstructed.

A little difference in the design and implementation of a seating or riser system can make or break your event.
