The Standards don’t specifically define a compliant room; they allow you to define the compliant viewing area as being within closest and farthest viewer distances and the horizontal viewing limits.

In real life floor space is expensive and sector-wide space metrics are applied to create construction budgets and inform the architect. It is rare for every seat in every space to be within the compliant viewing area.

Each institution should document the criteria within which designers must operate, defining:

  • Institution-specific Element Height or other parameters
  • What proportion of viewing positions must be within the compliant area for the design to be accepted?
    You will need two numbers, for those spaces with just one image and those where multiple discrete images are displayed.
  • Which boundaries are negotiable by the design team? Some institutions
    • define the farthest viewer distance as sacrosanct but will allow some seats closer than the standard allows; or
    • require 100% of seats to be within the horizontal limits

When defining or updating your internal design guide, remember those closest to the image may get a sore neck.

Anything affecting the budgeting or allocation of floor space or construction technique can only be specified and managed by your facilities management team. You must work closely with Facilities to agree physical environment standards that meet technical and budgetary constraints, and to have those principles mandated by your institution’s design standards.
