When considering the right size TV to buy, users may measure space to determine what size TV fits when looking for the best TVs. However, the size included in the description comes from the screen’s diagonal length and does not have a bezel. Therefore, to help people understand how wide is a 55-inch TV, they may need some formulas to use that estimate the height and width of the screen.

And, if you need to know how to hook up a VCR to a TV, we have a guide to help you.

KEY TAKEAWAYS:

• A 55-inch TV screen comes in at 47.9 in. wide and 27 in. tall.
• The recommended viewing distance for a 55-inch TV is about 7.7 feet.
• Many of the best features are available in 55 in. TVs.

## 55-inch TV Dimensions

Many consumers may seem surprised to learn that a 55” TV is considered a medium-sized TV. And if that is the case, then you must be wondering how wide a 40-inch tv is. However, in recent years, TV sizes have been increasing, causing TVs that used to be larger to fall under medium, or even small, categories.

For example, a TV that is 32 inches wide and 24 inches in height would be considered a medium-sized picture. On the other hand, a 55 inches wide and 35 inches in height television would be classified as large.

This phenomenon is because people place TVs in the same spaces, but the TVs are just bigger. Because of this, some may find it vital to select a TV size that fits the room where the consumer will place it. And if you are curious, you can read about two different sized TVs with our comparison of 43-inch TV vs 55-inch.

A 55” TV’s dimensions may seem like a bit of a mystery. However, the internet provides formulas that consumers may use to calculate the height and width of the screen. To do this, you may need to use the Pythagorean Theory or some trigonometry since you have the length of the diagonal and nothing else. In addition, you must know the aspect ratio for most TV screens, which you can also find online. This aspect ratio is 16:9 units, meaning that the width is 16 units and the height is nine units. Now the content that you watch has its own aspect ratio, so if you’re wondering why you’re watching a show and there are black bars around the content, you can fix that by learning how to adjust the TV picture to fit the screen.

The device you need to calculate the exact measurements is important, as some compatible devices may require an HDMI audio return channel or something else entirely. With all of this information, you can finally answer the classic question: how big is a 55” TV?

### Determining Height and Width

To simplify some of the math, you can multiply the diagonal (55”) by 0.87 to calculate the screen’s width and multiply by 0.49 to find the height. These formulas mean that the approximate size of a 55 in. TV is about 47.9 in. wide and 27 in. tall. This estimation won’t provide you with exact measurements for the screen, but it’s okay because the screen size is not always exactly 55 in. You will also want to add a few inches to the height and width because the bezel, or edge of the TV, is not included in the screen size. If these dimensions work for you, but you can go a little bit bigger, the best 60″ TV is a similarly-sized model.

### Determining Viewing Distance

Some manufacturers established guidelines for the ideal viewing distance for their TVs. Various aspects influence this distance, including the amount of your vision that the screen should take up and the space in which the eyes can easily recognize the image on the screen.

For movies, a larger viewing distance may be chosen to create the feeling of a theatrical experience while for products such as video games or desktop computers, closer viewing distances allow more control. By carefully selecting the ideal viewing distance based on what is being watched or used, users can maximize their experience and control.

For a 55-inch TV, the recommended viewing distance is about 7.7 feet. However, people should remember that this guideline is an estimate. To determine the ideal viewing distance for yourself, you could start around 7.7 feet away and move around to find the proper distance for you. If you need a TV for multiple people to view either for leisure or for workplace presentations during meetings, consider something like the best conference room TV which is an adequate size for such occasions. If you have a larger sitting room then you may want to check out how wide a 65-inch TV is and remember to consider the TV size vs the distance you will be sitting away.

## Available Features For a 55-Inch TV

Users may look for a large number of features available in 55” TVs. For example, some features improve the image resolutions, color, and features that enhance connectivity. Some of these features include 4K resolution, full-array local dimming, high dynamic range, and “smart” functionality.

### 4K Resolution

When it comes to TV, 4K refers to the resolution of the image on the screen. The number 4,000 (also written as 4K) refers to the number of pixels across the horizontal axis of a 4K TV. There may not be precisely 4,000 pixels across, but the number is pretty close. This high pixel count improves the images seen on the screen because each pixel represents a part of the image. This statistic means a high pixel count increases the available details. While your eyes may not be able to tell the difference at a certain point, your next TV will more than likely be a 4K TV anyway because most TVs made today are 4K.

### Full-array Local Dimming

Another image-enhancing tool that consumers may find in a 4K TV comes in the form of full-array local dimming. This feature refers to the arrangement of the backlight on a liquid crystal display (LCD.) Several formats exist for backlighting, but full-array local dimming provides excellent contrast between the brightest parts of the screen and the darkest. In addition, by enabling lights in some screen regions to turn off separate lights, the light from the surrounding pixels does not affect dark areas as much.

### HDR

High dynamic range (HDR) provides the screen with a broader range of color details, increasing contrast. The details on an HDR TV are revealed through exceptional contrast and deeper blacks. HDR also means increased brightness of the white areas on the screen. When combined with full-array dimming, the two enable higher contrast and enhanced details.

#### Smart TVs

Many users may look for smart TVs in the 55-inch size of televisions. This feature can be significant for users who do not have a cable or satellite subscription, becoming more common. In addition, smart TVs allow consumers to watch content from their streaming services on their TV screens. Although you can access this content using a streaming accessory, consumers may find it easier to access it directly through the TV, reducing the number of required accessories.

How wide is a 55-inch TV?

TV screens are measured diagonally from one corner to the other. For example, a 55-inch TV is 55 inches when measuring the screen only.

What is the PPI of 4k?

A 55” TV with 4K resolution contains about 80.11 PPI.

STAT: While your eyes may not be able to tell the difference at a certain point, your next TV will more than likely be a 4k TV anyway. (source)
