Screen Placement, Why Lower One-Third of the Screen Rule?
 
This may be a wrong thread to post on this topic, but I found many articles stating I should be using bottom 1/3 rule, but I'm abit confused about that rule. Wouldn't that cause you having to lookup?
In an office space, I'm always told that my eye level should be on the top of the screen. So I'm abit confused...What's the reason behind this rule, and why the difference?

I did the same 1/3 but found myself looking up. So I lowered it down. Now I am at 40pct instead of 33pct. Its a personal choice.

That height is a starting point to try and accomplish many goals, some of which include:
  • high enough so your feet don't obscure your view when you recline
  • high enough for a second row to see over a first row
  • shouldn't require you to look "up" at your screen
  • top is far enough below an 8' ceiling to help with reflections
  • speakers can be placed behind the screen to easily land at ear level
  • looks natural on the wall

It's not a requirement, it's just a really good reference starting point. Tweak from there depending on your room and preferences.

Yeah i would take reclining into account - that usually results in tilting your head back, looking up.

If sitting upright, it would seem intuitive that eyes centered on the screen would be optimal.



But for a larger screen, and for setups where a center speaker or sub needs to find space below the screen, and for multiple rows of seating without dramatic height differentials, that seems infeasible.



And reclining that involves resting the back of the head raises the angle of vision. I'd be curious how many people here prefer to watch movies with a relatively vertical cervical spine versus resting their head. Personally, while I like the option to recline, I prefer to have my head upright during a movie.
