View Full Version : Suggested Minimum Viewing Widths for Your Home

Here's a quick guide for any of you looking to get a new TV. There are 2 competing standards which specify the ideal viewing angle for a good cinematic experience.

Basic Criteria (http://www.thx.com/professional_services/sound_criteria.html)

THX states that the ideal minimum viewing angle is 36 degrees to the farthest seat, with 26 degrees being a minimum.

SMPTE standard EG-18-1994 recommends a minimum angle of 30 degrees.

Here's a good calculator for us to use:

Let's say my room has a 12' viewing distance. It's a pretty standard sized room, not too big.

From this, we see that to meet the minimum SMPTE standard, we need a 75.6" wide screen, which means a 94.5" diagonal for a 4:3 TV screen, or an 86.7" diagonal for a widescreen 16:9 TV.

To meet the ideal minimum 36 degrees for THX, we need a 90.8" wide screen, which translates to a 113.5" diagonal 4:3 TV Screen, or a 104.2" diagonal 16:9 screen.

Let's look at from the standpoint of a TV.

If you have a 30" widescreen (16:9) TV, you should sit no more than 3.5 feet from it for the recommended 36 degree viewing angle.

If you have a 34" widescreen (16:9) TV, you should sit no more than 3.9 feet from it for the recommended 36 degree viewing angle, with 5.4 feet being an absolute max at 26 degrees.

If you have a 36" standard 4:3 TV, you should sit no more than 3.8 feet from it for the recommended 36 degrees, with 5.3 feet being an absolute max at 26 degrees.

For a widescreen 53" projection TV (16:9), you should sit no more than 6.1 feet from it for 36 degree angle, and no more than 8.5 feet as an absolute maximum for a 26 degree viewing angle.

One thing to note is these guidelines are simply a baseline for a good cinematic viewing experience. A wider viewing angle will give you a more immersive experience and lend to the "suspension of disbelief" that we want to accomplish when watching a video. Larger angles will also reduce eyestrain (though this can also be accomplished with D65 bias lighting).

"Suspension of disbelief"...Is that like a double negative?

1.4 feet recommended distance from a 13" TV!! :heh:

I'd be more interested in seeing the MAXIMUM viewing width for my home!

Man, I wish I had a DLP. :(

so basically, this told me what i already knew -- my tv (25") is too small :bawl:

but i'll do with it for now, because i don't think santa is going to be bringing the recommended 60" tv anytime soon :heh:

nah, my apt is too small for anything big, maybe a 32" will be the max.

shoot, any bigger, and it wont fit thru the door!

yes, my apt IS small!

You need one of those Samsung DLP sets then. The 50" one is 17.6" thick.

Heck, at 77lbs, it's probaby lighter than a 32" as well (at a cost that will lighten your wallet too).
