The Truth About 55-Inch TV Dimensions

Before you get confused with many calculations, let’s learn about 55-inch TV dimensions in detail.

It’s easy to assume that if a TV is 55 inches long, it must be just as wide. But the reality is a bit different. Despite the name, these TVs aren’t exactly 55 inches wide, and the width is a bit narrower than the diagonal length.

Now, let’s have a closer look into the specifications and learn how big and wide is a 55-inch TV and how TVs are measured.

55 inch tv width and height

1. The Width of a 55-Inch TV

Suppose you are standing in front of your TV, and you measure its width from one end to the other. But if you were to measure the diagonal distance from one corner of the screen to the opposite corner, it would likely be around 55 inches. That’s where the name comes from. But the actual width, the distance from side to side, is a bit smaller than that diagonal measurement.

Most 55-inch TVs have an aspect ratio of 16:9. Imagine the TV screen divided into equal parts, the width takes up two of those parts, while the length takes up the other two. So, when you do the calculation, the width ends up being about 47.94 inches (or roughly 121 cm).

Hence, it is important to remember that the 55-inch measurement refers to the size of the screen itself, not the entire TV. The frame around the screen does add a bit of extra width, but the frames of modern TVs are often slim, so their impact on the overall size is minimal.

2. The Length of a 55-Inch TV

When you imagine a “55-inch TV,” you might assume that it’s 55 inches long from end to end. However, this estimation isn’t entirely accurate. The name of the TV is actually derived from the diagonal measurement of the screen, which is close to 55 inches when you measure from one corner to the opposite corner.

Moreover, the length of the TV which is the distance from side to side, is influenced by the TV’s aspect ratio, typically 16:9 for most modern TVs, including the 55-inch ones. To understand this better, imagine dividing the TV screen into equal parts. The width occupies two of these parts, while the length covers the remaining two. And as a result, the length of a 55-inch TV is about 30.96 inches (or around 78.5 cm).

Please note that this length is calculated without considering the stand. If your TV is mounted on a stand, you will need to consider the additional space it occupies. This might add around 3 inches (approximately 7.62 cm) to the overall height of the TV.

3. The Thickness of a 55-Inch TV

Unlike the width and length, the thickness of a TV isn’t determined by its diagonal measurement. Instead, it’s ascertained by the hardware and components enclosed within. Imagine it as the TV’s backstage area, where processors, ports, connectors, and other essential parts together create your entertainment experience.

In the case of most modern 55-inch TVs, you will find a thickness of around 2 inches. However, keep in mind that the actual thickness can vary depending on the TV model and manufacturer. Some TVs might be slightly thinner, around 1.7 inches, while others might have a depth of around 2.2 inches. These subtle differences might not seem significant, but they contribute to the overall aesthetics and functionality of the TV.

Also, keep in mind that if your 55-inch TV is placed on a stand, the depth can increase by a few inches. Including the stand, the TV’s depth might be around 12 inches (approximately 30.5 cm).

Optimal Viewing Distance for a 55-Inch TV

You have purchased a sleek 55-inch TV and are ready to watch your favorite shows and movies, but have you ever wondered about the perfect spot to sit? 

For a 55-inch TV, a commonly recommended rule of thumb is the “1.5 to 2.5 times the diagonal screen size” guideline. This means that if you are sitting about 6 to 10 feet (approximately 1.8 to 3 meters) away from your TV, you are at the right distance. This range balances the feeling of a big screen with the comfort of not having to move your head or eyes too much.

But remember, these numbers are just guidelines, not strict rules. Personal preferences, the layout of your room, and your eyesight all play a role. Additionally, take into consideration the TV’s resolution. If you have got a 4K TV, you can comfortably sit closer without noticing pixelation. On the other hand, with a standard HD TV, you might want to stay within the recommended range to enjoy the best picture quality.
