I'm getting itchy to buy a new HDTV monitor. My question is: If I know how far I plan to sit from the set, how big a 16x9 widescreen TV do I need to purchase? Is there a formula to calculate the optimum size (in diagonal inches) based on the distance between my eye and the screen?


I don't want to buy a monster that makes me feel like I'm sitting on the first row in a movie theater. But then, I want to buy the largest set where I still feel comfortable watching it.


I currently have a 27 inch traditional monitor that I watch from 6 or 7 feet away. While it is okay, I would like something larger now for movies.

I think I read in an earlier post that you take the distance in Feet from the TV and multiply by 6 for the inch screen you need. at 6 feet away you would want a 36 inch tv. I hope I remember that right.

I do not know any formula but 36 is way too small to me. I have a 56 rptv. The distance is about 6 or something. I hope I had a bigger one. But for non HD program, 56 is big enough.

I believe this has been talked about a number of times. You might want to do a search and see what you find. THere is actually some rule of thumbs but I can't remember what they are and little swamped to go searching for them. However, there is no right rule. 60" at 7 feet might feel wrong for most people but some people think it is ideal.


Having said that.. I am 11' from my 60" and have a cheap seat at 7' with a bad angle and I dont feel it is horriable.

Do your search for past discussions as suggested. We have experienced the "shrinking" phenomenon that you will see has been discussed. Our 65" looked HUGE for about a week but has slowly started "shrinking". It is amazing how adaptive the brain is.


BTW, we sit 12' - 14' away from ours.

Anything over 50" is too big, unless you have some sort of falic complex.


A toshiba 42hdx82 would be near perfect at 7'.

Much of thie size issue has to be balanced with what you are used to. I am replacing my 26" with a 50" as this gives a MUCH larger picture but will be no way close to the home theater impact that many go for - my viewing distance is about 13 feet. For my wife, the 60" or larger was just too much to take - it would dominate a wall. It also depends upon what you are planning to view. In my case, there will still be a lot of regular television and I really do not need to see Dan Rather life size! There is also a possible picture quality trade off if you view a lot of cable or satellite. With the lower quality inputs, a larger screen tends to emphasize the defects. While I would love a 70" screen for DVDs, I have to bend to the wife on this issue.

This is almost a guarantee rather than a possibility. Do yourself a favor and condsider this very carefully when weighing all of the info. This is really my only major complaint with my 65" and I knew it going in. Sitting less than 10' away while watching a garbage source on sets as big as you are considering is likely to make you sick.
