TV
sizes and viewing distance
How to choose the right screen size for your room
The expression "bigger is better" actually makes a pretty
reasonable guideline when you're trying to decide on TV screen size. Our
experience has been that in most situations — and especially when choosing a TV
for your main room — you should go with the largest screen your room, viewing
distance, and budget will accommodate. That's because we occasionally hear
people wishing their TV's screen was bigger, but rarely hear them wishing their
screen was smaller.
Viewing distance and picture quality: two parts of the screen size
equation
Sitting the right
distance from your TV is also an important part of optimizing the viewing
experience. If this will be your first big HDTV, you may end up re-thinking
your setup and viewing distance. Old-school tube TVs typically had screens
36" or less, and you didn't want to sit too close because if you did you'd
notice the screen's scan lines. But with current TV models, sitting too far away
may mean you miss some of the high-def detail you paid for.
But you also want to
avoid sitting too close to your TV. A good indication that you're sitting too
close to a screen is if you find yourself distracted by the screen's
"structure" — those rows and columns of pixels that look like tiny dots.
If you're not sure
which screen size is best for your room size and viewing distance, use our
charts as a guideline. It might also tip you off to how your current
viewing distance lines up with industry recommendations. You'll notice that we
provided a range for
each screen size, rather than a hard and fast number. That's because the
viewing distance you prefer will depend on your personal tastes, as well as
what kind of material you'll most often watch.
If you watch lots of
high-quality video — like Blu-rays and high-def cable, satellite, or
over-the-air programming — you can sit at the closer end of the range to see all
the detail your HDTV can provide. On the other hand, if you'll still be
watching lots of lower-quality sources, like analog cable, we recommend sitting
at the higher end so that you'll notice less of the image's flaws.
You'll notice that
the chart on the left applies to HDTVs, which usually have "1080p"
screen resolution. The chart on the right applies to 4K Ultra High Definition TVs, which
have much higher resolution screens, with the ability to show four times the
detail of a 1080p screen. The pixels on Ultra HD screens are incredibly small —
even standing right next to the screen it's hard to discern individual pixels.
This means you can sit much closer to an Ultra HD TV than to a regular HDTV —
as close as 1 times the screen diagonal.
A few more tips
on TV placement
Viewing
angle
Viewing angle is another factor that affects TV picture
quality. No matter what display technology your TV uses — LCD, plasma, OLED —
it will look its best when viewed straight-on, at a height where your eyes are
level with the middle of the screen. With that in mind, you'll probably need a TV stand to support your TV and raise it to the
correct viewing height.
Today's skinny,
lightweight flat-panel
TVs give
you options: you can either go with a stand, or use a TV wall mount for on-wall placement. Wall-mounting saves
considerable floor space and gives your home theatre a nice, finished look. See
our guide
to wall-mounting your flat-panel TV for
more detailed on-wall TV placement tips.
Safety
You'll want to make sure you choose a stand or wall mount that's made to accommodate your TV's weight and size — an old coffee table may not be able to stand up to the weight of really big TVs — say, 65" or larger. Also, be sure that your TV is placed properly on your stand, and that it's balanced left to right, and front to back. If you have small children, wall-mounting your TV is a good way to reduce the chances of an injury caused by a TV tipping over. Or, if you're placing your TV on a stand or other furniture, a TV safety strap is a smart safety option.

Rather than the
traditional pedestal stand, many new TVs are supported by two legs placed out
near the edges of the screen. You'll want to be careful not to place your TV so
that the legs are close enough to slip off if the TV is bumped. Since TVs tend
to be heavier towards the front, you should avoid setting them too close to the
front edge of the stand.

Room lighting and your TV's picture
Light from lamps and
windows can also affect your TV's picture. Properly done, it can have a
positive effect, helping to prevent eye strain and providing deeper-looking
blacks. But in a lot of cases, it can have a negative impact; creating
on-screen glare and making your TV's colors look faded and washed out. If your
viewing room has a lot of ambient light from lamps and windows, there are some
simple steps you can take to prevent it from negatively affecting your TV's
picture.
- If you can, take room lighting into
consideration when choosing a spot for your TV. A little furniture
shuffling might be worth it if it means your TV won't be directly across
from West-facing French doors that create afternoon glare.
- Any windows that let in bright sunlight should
have easily adjustable blinds and/or curtains capable of eliminating any
reflections off the screen.
- Light from a window behind the TV makes it
difficult for your eyes to adjust to the very different brightness of the
TV screen. For watching during daylight hours, consider treating these
windows with curtains and blinds.
- If you're concerned about glare in your room,
consider an LCD TV — their bright, anti-reflective screens generally hold
up the best in well-lit rooms.
- With just about any TV (except a projector),
it's best to have a little bit of light shining on the wall behind it. If
you watch in total darkness, the TV's range of brightness can cause
eyestrain.
- Using dimmers in your home theatre room, you
can precisely control the amount of background light for optimum viewing
comfort, plus you can achieve elegant lighting effects. There are simple,
inexpensive dimmers for controlling lamps. And for the greatest
convenience (and the biggest "wow" factor), look for dimmers
that are remote-controllable.
