Hi Geeks & Geekesses

Well it looks like I'm finally going to relegate my 29" Panasonic CRT with its high-tech composite terminals to the back bedroom and replacing it with the latest 'V' series Panasonic Plasma. The problem is size! The room is only 3.6mtrs across. So to try and maximize the feeling of space I'll mount the TV on the wall which means my eye to screen distance would be about 2.9 - 3.0 mtrs.. But what size? According to fellow Home Theater fans to get the optimum size to distance of 1.5 my TV would have diagonal size of 2.0mtrs !! WAF just went out the window! I was thinking of a compromise size of 55", whats that, about 1.4mtrs. The wife though will only go as big as 50" (1.27mtrs).

So what do you think the optimal size in actual every day use should be. Does sitting 1.5 from your large TV just seem a little daft to get the 'cinema' experience or does practicality take over. What size did you want and what size did you end up feeling most comfortable with.

Thanks

I think you have been given a bum calculation, your optimal viewing distance according to THX is the set size (diag) divided by .82 ( or multiplied by ~1.2, )

Thus your 1.5 m viesing distance works out as a set size of 1.3m- so if you go for 50" you should be sweet.

http://www.thx.com/consumer/home-entertainment/home-theater/hdtv-set-up/

How do you calculate the best seat-to-screen distance for a plasma, LCD TV or projection screen? Divide the size of your screen by .84 (screen size is measured diagonally). For example, a 65-inch TV divided by .84 equals a 77-inch viewing distance (6.5 feet).

Seat-to-screen Viewing Distance Calculations

If your HDTV is going in a living room with limited space, THX recommends the following:

35 inch class TV = 3.5-5 feet away

40 inch class TV = 4-6 feet away

50 inch class TV = 5-7.5 feet away

60 inch class TV = 6-9 feet way

It might seem that THX is recommending a very large screen size for your room. But, it’s important to note two things: 1) THX screen size recommendations are based on recreating an immersive cinematic experience, and 2) the biggest complaint among TV buyers is that they wish they had bought a bigger set.

I work on the calculation that there is no such thing as to big and whatever size you go for will look big for a week and then you will wish you got the next size up!

I went for 100" projector and sit about 3.5m back :-)

Forget the techno stuff. My rule is to buy the biggest baddest screen that:

1. You can afford
2. That the wife will let you
3. That will fit on the wall
4. That won't give you a sun-tan or heat-rash

TV's always look big when you get em because of the "wow" factor. But that soon subsides and as stated above that's when you will wish you had gone just that little bit bigger.

Good luck

Lazy is such an ugly word, I prefer to call it selective participation

Since we moved, we're now sitting about 1.5 to 2 metres from our 52 inch.. Looks far better than previous house where we were about 4 to 5 metres away from it.

One thing to be aware of is that while great content will look really good when you're sitting close, bad content may well be unwatchable if you have good eyes.

We run a two stage system - 46" TV a good 5m away from the sofa allowing a "socialable" and open room setting, with beanbags we can simply drop in up close for a "better than cinema" experience. The only downside to this is getting the speaker distances synch'd with the viewing position, but a halfway solution seems to suit both scenarios fine.

If you are mounting on the wall, do you also mean you are mounting higher than 'ideal'? If so you need to factor that in, and may want to be further back than you otherwise would.

Humans are kinda dumb when it comes to adaptability, in that we're too good at it. You will adjust to pretty much any set up.

Gotta say there's just about as much crap published about viewing distance and angles as there is about cables. By all accounts our sound system and viewing distance/angle should be rubbish.....but it's great, for US. Do what works for you.

As earlier stated - forget about opyimal distance. Just buy the biggest badest screen you can afford and then in 6 months time wish you had had more $$$ to have brought an even bigger one. There is no such thing as to big.

the reason for asking, my friend has 50 inches tv with similar distance as mine. when i watch from couch it looks good but if i step a bit back (about 1m) it was looking even better.
