Yes, if you have a huge living room then a giant TV is great. So, what size is right for you? You can figure out pretty quickly by deciding where you plan on sitting to watch it and measuring the distance between there and where you plan on placing the TV. According to Samsungthe right TV size is the viewing distance in inches divided by three. When you divide by 3, you get That means that the right TV size for your room is 40 inches.
Viewing angles are also something to consider once you make that purchase. If you are seated at a sharp angle to the TV, you may see negative images on the screen. Most major manufacturers will tell you the maximum viewing angles at which you can watch the TV without seeing negative images.

HDTV is designed to provide an experience more realistic than the television system it is designed to replace. A larger display increases the visual angle at which content is viewed, both of which contribute to an increased feeling of presence.
Lechner did an early analysis of viewing distance under various conditions, deriving the so-called Lechner distance. It was later established that television viewers could also experience a feeling of presence. The ideal optimum viewing distance is affected by the horizontal angle of the camera capturing the image. One concept of an ideal optimal viewing distance places the viewer where the horizontal angle subtended by the screen is the same as the horizontal angle captured by the camera.
If this is the case, the angular relationships perceived by the viewer would be identical to those recorded by the camera. A mismatch in this regard is traditionally disregarded, but some rotating motions can make these distortions very noticeable as a pincushion effect.
This is likely in 3d video games, so gamers are likely to adopt close viewing positions matched to a game's fixed field of view.
If the camera's angle were always the same, an optimal viewing distance could be easily calculated. However the camera's horizontal angle varies as the focal length of its lens changes.
If the camera's sensor has fixed dimensions, a shorter focal length wide angle lens captures a wider angle of view, requiring the viewer to sit closer to the screen. Conversely, a longer focal length telephoto lens captures a narrower angle of view, demanding a more distant viewer position. Such opposing viewing distances would not only be impractical, but would negate the very purposes of telephoto shots for example, to see a distant object in more detail, or minimize distortion in facial images and wide-angle shots causing the viewer to sit too close to the screen, where undesirable image artifacts would be visible.
One compromise assumes the lens is "standard" a 50mm focal length, for a standard 35mm format. A "standard" lens preserves the same spatial relationships perceived by a spectator at the camera location. For a "standard" lens image, viewing distance should be equal to the diagonal length of the screen. It has been demonstrated that viewing a display that occupies a greater visual angle also referred to as field-of-view increases the feeling of presence.
With printed graphicsresolution refers to the number of pixels usually referred to as "dots" in a fixed linear measurement. For a HDTV's image to noticeably improve, its resolution per degree of arc or angular resolution must increase as well as the pixel count of the display. To maximize the feeling of presence and thus provide a better viewing experience, the viewer would need to be situated at the theoretical spot where the HDTV occupies the widest view angle for that viewer [ dubious — discuss ].
It is also important that the resolution of the display per degree of arc remain at a high quality level. Recommendations on HDTV viewing distances fall into two general classes; a fixed distance based on HDTV display size, or a range of distances based on the display size. The most common recommendations from reasonably authoritative sources are presented below. Fixed distance recommendations are the more common of the two types.
For the most part, the majority of the fixed distance recommendations were issued before the end ofwhen arguably HDTV displays were still in the early adoption phase. One of the more popular recommendations on the proper HDTV viewing distance is multiply the diagonal measurement of the display screen by 2. This recommendation is cited by television manufacturers,  retailers,  respected publications   and websites though the popular electronics review website CNET suggests that high-resolution content can be watched at a closer distance — 1.
This recommendation is very popular with the home theater enthusiast community,   appears in books on home theater design,  and is also supported by a white paper produced by Fujitsu. For consumer application of their recommendations, THX recommends dividing the diagonal screen measurement by.
This equates to multiplying the diagonal measurement by about 1. Stating optimum viewing distance as a range rather than as fixed distance is on the rise; possibly because of changes in the profile of the typical HDTV purchaser. Early adopters of HDTV were typically videophiles the technically adventurous  and the sports enthusiast  looking to have the ultimate viewing experience.
Today, the typical HDTV consumer's aims may be a little more modest; total immersion takes a back seat to room integration. Range recommendations from manufacturers are the most modest of the groupings. For the minimum or nearest viewing distance, they recommend a view angle of approximately 31 degrees; and for the maximum, a view angle as low as 10 degrees. The recommendations currently posted on the websites of retailers Best Buy and Crutchfield take more of a middle ground.
Both retailers post a minimum viewing distance that accommodates a view angle of just a little over 32 degrees on average.With so many shows targeted to very young children, it might not seem like a big deal to let your toddler watch an episode or two of a favorite cartoon.
But your child is growing up in a media-saturated world, and now is the time to start teaching her healthy habits for managing screen use. A little TV or other screen time is fine as long as she's watching age-appropriate, high-quality shows along with an adult.
But too much or inappropriate TV can interfere with healthy mental and physical development and lead to long-lasting problems. Below are tips for managing your toddler's viewing time.
Limit TV or screen time. The AAP recommends no screens at all for children younger than 18 months. To keep your child's brain from going on autopilot as he watches, break up viewing into to minute increments.
Keep screens out of the bedroom and turned off during meals.
Set the rules right away. Setting up rules from day one makes it easier to keep viewing time under control as your child grows older. It's a lot easier to relax your standards later than to wean an month-old from a habit of watching whenever he likes. Make watching a privilege. Don't let screen time become an expectation.
This is counterintuitive, but it's surprisingly effective. You may have a number in your head, but if your child knows what it is, he might view it as the amount he "should" be watching. Make screens inconvenient. Consider keeping the TV and other screens in a small, out-of-the-way room in the house or in a cabinet that remains closed when it's off.
Turn off the TV when no one is watching: Background shows are distracting, and they reduce interaction between parents and young children. Stick with simple programming. Slow-paced programs give small children time to think and absorb.
Choose straightforward, age-appropriate shows that emphasize interactivity.
Ideal shows inspire your child to makes sounds, say words, sing, and dance. And some research suggests that kids who watch violence on TV are more likely to display aggressive behavior. Watch specific shows. Rather than allowing your child to watch whatever happens to be on, carefully select shows. Check reviews from trusted sources like Common Sense Mediaand preview shows before watching with your toddler.
When the show is over, turn off the screen. A two-minute warning with a second countdown that screen time is about to end will help your toddler transition to the next activity. Watch with your child. Try not to use videos or television as a babysitter. Research shows kids do better if an adult is around to reinforce learning. That aside, just being there says to your child, "What you do is important to me.
Help your child watch critically. Even young children can learn to watch without "tuning out. Encourage your child to ask questions and relate what's happening in the show to her own life. If you're watching a video or recorded show, pause the show to discuss what's going on. Connect the show to the real world. By joining your child during screen time, you can help her make connections between what she viewed and the real world around her.A bigger TV can actually detract from your home viewing experience.
Keep reading to see how you can calculate how big of a TV you need for an optimal viewing experience. Simply use the slider to set your viewing distance and select your resolution. The calculator will then present the optimal TV screen size for the given variables. By using this calculator as a guide, you can optimize your home theater experience.
To use the chart, pick your anticipated viewing distance from the y-axis and then match it to a resolution and size on the x-axis.
The Ideal Distance for TV Viewing
Before you spend hundreds of extra dollars on a 4K TV, you might want to think about downgrading to p instead. Ultimately, while all this math can help you determine the optimal TV size, resolution, and viewing distance, the most important factor is comfort. In general, most people prefer to sit pretty far away from their TV. At a distance of around 10 feet, the resolution becomes less of a factor. Most people interested in this type of information are already working with a fixed room and are looking for the best TV to fit the space.
This is a great way to optimize your viewing experience without sacrificing your comfort. Lastly, you need to take your budget into account when using the above calculator to determine the best TV size and resolution for you.

How to Calculate the Optimal TV Screen Size Based on Resolution and Distance
I have a 60" in my family room that I sit about 8' away from, so I'm having a hard time judging what will be decent for the bedroom Aug 22, 6, 7 Use this viewing-distance calculator to determine your viewing angle given a certain screen size and viewing distance. For example, a 32" TV at 12' has an A 60" TV has that same viewing angle at 22'. So, if you can read subtitles on your 60" from 22' away, then you'll be able to read them on a 32" from 12' away, because they'll be the same size.
What Is the Best Viewing Distance to Watch a TV From?
In other words, you'll likely need a bigger TV than 32" at that long of a viewing distance if you want to be able to read the subtitles. You could also go to a store, turn subtitles on for different TV sizes, measure a distance of 12', and see if you can read them. Edit: Oops, forgot the calculator link. YOyoYO's post reminded me though. Last edited: Feb 22, Aug 6, 31, 29 You'd have to be 28 feet away from a 60" TV for it to look the same size as a 26" TV from 12 feet away.
A 26" TV from 3.Dear EarthTalk: Years ago I read that children should be kept at least two feet from the television because of harmful electronic emissions. Is this still relevant? Is there a difference regarding this between older and new flat-screen models? Mehring, Oconomowoc, Wisc.
This myth prevails because back in the s General Electric sold some new-fangled color TV sets that emitted excessive amounts of radiation—as much astimes more than federal health officials considered safe. GE quickly recalled and repaired the faulty TVs, but the stigma lingers to this day. But there is an easy cure for eye strain and fatigue: turning off the TV and getting some rest. There has also been much debate in recent years on the effects of TV viewing on infants.
While it may be inevitable that your kids will watch TV, the key, experts say, is moderation. BoxWestport, CT ; earthtalk emagazine. Read past columns at: www. EarthTalk is now a book!

These modern flat panel screens do not emit radiation. However, many people still worry that they may injure their eyes by sitting too close to the TV.
So how close is too close? What is the ideal distance for watching television? The answer may be surprising to some, but there really is no magic formula for calculating the precise distance. Some eye care professionals recommend sitting approximately eight to ten feet away from the TV screen. The general rule of thumb is to be at least 5 times the distance from the screen as the screen is wide.
For example, if your television is 32 inches wide, the optimal viewing distance is inches or about 13 feet. However, most optometrists and ophthalmologists agree that the best distance for television viewing is the distance that feels most comfortable for you. As long as you can see the screen clearly without experiencing discomfort, the distance is probably correct. Whether you hang your TV on the wall or set it on a tabletop, try to position it at eye level or lower to prevent straining your vertical eye muscles or your neck.
Constantly forcing your eyes to look up will eventually cause the eye muscles to fatigue. Lastly, as different types of screens have become more common in homes, the American Optometric Association promotes the rule. They suggest that you take a 20 second break every 20 minutes to view a distant object that is 20 feet away.
So, for example, if you watch your favorite movie or tv show on your laptop, take regular breaks to avoid eye strain. Attempting to focus on a close object for an extended period of time causes the ciliary muscle to tighten, producing the symptoms of eye strain. Symptoms include:. The average person blinks around 18 times a minute, naturally refreshing and lubricating the eye. But some studies have shown that people may only blink half as often or less while looking at a television or computer screen.
Besides sitting too close, watching too much television can also cause eye strain due to constant focusing on a small, bright object in a dark room. Eye doctors recommend a simple technique for preventing eye strain. If you are staring at a screen for an extended amount of time, shift your focus from near to far on a regular basis. Shift focus from up close to at least 20 feet away, for example. If you experience the symptoms of eye strain after watching television or looking at your smart device, here are a few things you can do to help alleviate your discomfort.How Far Should You Sit From Your Screen?
With this condition, a person doesn't have enough quality tears to lubricate and nourish the eye. Tears are necessary for maintaining the health of the front surface of the eye and for providing clear vision. Staring at a screen for long periods of time can dry out the eyes. Dry eye syndrome is often treated by frequently instilling quality eye drops and other therapies. It seems that many kids today tend to watch their iPads and smartphones more than they watch television.
Should parents monitor how close their kids hold their screens away from their eyes? Most eye care professionals agree that tablets, phones, and laptops are harmless to eye health and vision. However, these devices can cause eye strain, much like watching a television.
Symptoms can develop due to focusing on a much smaller screen at a very close distance to your eyes. Handheld digital devices such as smartphones should be held below eye level.
If your child seems to have difficulty holding his devices at this distance, he might try enlarging the text on the screen. Adjusting text size can sometimes make viewing more comfortable.
