how wide is a 55-inch TV

• A flat-screen TV’s size is often determined by drawing a diagonal line from the top left corner to the bottom right, or, if you like, from the bottom left to the top right.

• Typically, this clearance is expressed in inches. In their product lineup, companies will provide a choice of sizes.

• The breadth or height of a television screen may be used to determine its size. The diagonal length is, however, the usual method.

• There are now two primary categories of TVs: LED TVs and OLED TVs. You may be shocked to hear that these two varieties are offered in a wide range of screen sizes.

• TV sets come in sizes ranging from 15 to 80 inches. in certain circumstances, even more.

• OLED TVs, however, are only offered in bigger screen sizes. often between 50 and 85 inches.

• Therefore, take in mind that the sort of technology you desire may affect the screen resolution you choose.

• How do you choose the right screen size for your space after you’ve decided on the sort of HDTV you want? And from how far away should you watch TV?

Determining the best display size and the best viewing distance of the TV set

One thing to realize is that this is not an exact science. A size comparison may be ideal.

But ultimately, there is more than one factor that can affect your opinion on the right size TV for your room:

  • Personal taste
  • Location in the room
  • The resolution of the TV pictures you’re watching.
  • Even the quality of your view!
  • Two people can put two in the same room, and both people may have different attitudes about the correct screen size and the best viewing distance.

However, it can be helpful to get some solid numbers to give us a starting point, so let’s consider how we might do this. Although many times having a much larger screen can come at a very high Price, some devices are worth it.

Recommended viewing distance according to the field of view

In terms of television viewing, the field of view (FOV) is the viewing angle between a person and the visible area of a television screen.

As you get closer to the monitor, the wider the field of view will be, and the more immersive your viewing experience will be. However, if you get too close, the field of view is likely to be too wide for most people. 

Have you ever sat in the front row of a movie theater? It would be best if you practically turned your head to see the action at the far ends of the screen. In that case, you might say the field of view is too broad – you might like it! The field of view commonly refers to a reasonable viewing distance. None of the guidelines advise how close you can get, just a maximum suggestion of how far away you should be.

Remember, the smaller angle is farther away, and the larger angle is closer to the screen.

Therefore, less than 26° will most likely be too far for many people.

And more than 36° will be more immersive, but it will reach a point where it will be too close.  Also, it would be best if you kept in mind that these recommendations are for an actual movie theater.

So, while you can use them as a guide throughout your entire home, most people will often need to make some compromises. One other point to consider is that these suggestions do not consider the resolution of the image.

The suggested field of viewing will vary with the size of your screen. Fortunately, we can easily calculate recommended viewing distances with the TV viewing distance formula.

Recommended Viewing Distance based on Image Resolution

A television screen has a fixed native resolution. Ideally, the image you see on that screen will have the exact answer. However, if you move away from the TV screen, there comes the point where you cannot see all the details of the picture.

Depending on the screen size and picture resolution, this range will vary. Consequently, the more you move away from the longest distance, the minor detail you will see.

And the closer you get the more imperfections you will see in the resolution of the image. So, if you want to be able to see all the detail on your high-resolution screen, there is a recommended distance you should sit from the screen.

So, this is another way to decide the best viewing distance for your TV. It would be best to keep in mind that this distance may vary depending on the person watching the screen. Visual acuity will differ from person to person.

It remains commonly accepted that people with 20/20 vision can distinguish details as small as 1 minute of arc, or 1/60th of a degree. Therefore, as the resolution of the TV increases and the pixels on the TV get smaller, there is a limit to how far we can see this detail.

Recommended Viewing Distance based on a Range

The two solutions above will not necessarily give you the same recommended viewing distance. Therefore, you will need to choose one or the other or find a compromise distance that gives you the best balance between the two.

There’s not a right or wrong thing to do in this case. It often depends on individual taste, sight, or the use you make of the screen in your room. So in the unlikely event, you do not want to choose one or the other or find that getting it exactly right is not convenient or adequate for your environment. Another possibility is to use a range rule of thumb to give you a range to aim for.

A popular rule of thumb is to use one foot of viewing distance for every 10 inches of diagonal screen size.

This may sound more complicated than it is:

  • A 70-inch screen at 7 ft.
  • 60-inch screen at 6 feet. 
  • A 50-inch screen at 5 feet.

This gives a field of view of about 40°, which is a little closer than the THX recommendation of 36°.

However, this is a reasonable distance for those who want to be close enough to get an excellent immersive experience without being too close. Of course, if you like to be even closer, that’s up to you.

Something like this can perhaps provide a starting point for a recommended viewing distance range.

The bottom end of the scale will allow a field of view of about 40°.

The higher-end will give you a little more than the maximum distance allowed according to THX guidelines so about 20° instead of the THX maximum of 26°.

It will allow for a home movie theater is much more likely to fit in a typical living area than in a dedicated theater space. Therefore, a greater distance may be required.

Anything in this range will work well. You only have to decide whether you prefer to be closer (for a more immersive experience with more detail) or farther away.

Of course, these are just general guidelines, so feel free to move closer or further away from this if it works best for you and your room.

Some TV models such as the Roku Smart TV, LG C9 Smart, LG C9 Smart OLED TV, TCL 3-Series Roku Smart TV have revamped digital TV. Today the advent of streaming has helped open up endless possibilities and uses for our Smart TV. Having a TV that is independent of cables can be a solution to avoid the clutter that commonly occurs in the rooms.

To quickly find out what size you should buy, you can divide the viewing distance of your TV (in inches) by 1.6 or use a TV size calculator, which is roughly equivalent to a 30-degree angle. If the best size is out of your budget, get the most prominent TV you can afford.
