How Do You Measure TV Dimensions? 55-Inches TV Dimensions

How Big is a 55-inch TV - How to Measure the Dimensions
How do I measure the TV dimensions?

Take a tape ruler to measure the dimensions of the TV. However, the dimensions of the TV are measured by measuring the TV’s width, height, thickness, and diagonal distance.

  • Width: The width of a TV is measured from one side to the other side
  • Height: The height length is calculated from top to bottom
  • Thickness: The thickness of a TV can be easily calculated from front to back
  • Diagonal Distance: A TV is diagonally measured from one corner to another corner. You need to take the distance from the upper right corner to the lower left corner or from the upper left corner to the lower right corner.

How to Measure 55-Inch TV Width?

More often, when we take the width of a TV, the resultant aspect ratio comes out at 16:9, which means there would be two sides: one width and the other length.

The width would be 16 inches, and the length would be equal to 9 inches. However, most TVs have a 47.94 (121 cm) width.

Suppose you consider a 55-inch TV screen is also 55 inches, but you might need to be corrected because a TV is larger than the frame due to the frame. Modern TVs such as TCL or Samsung, come with a narrow bezel with a minor impact.

These 55-inch TVs Are trending today.

How do I measure the height of a 55-inch TV?

Measuring the height of a 55-inch TV can be a little hectic. This is because you must consider the measurements with or without a stand. The TVs that are being manufactured now come with legs.

They can stand without any support. Similarly, some TVs can be easily mounted on the walls. In this case, you need to measure the height of the TV.

But, sometimes, you need to use a stand for your TV. Then, you have to measure the length of the stand as well. I prefer using a stand for a 55-inch TV.

So, the height of the TV without a stand is 27 inches (68.5 cm), but with a stand, the height increases by 3 inches (7.62 cm).

How do I measure the thickness of a 55-inch TV?

I know the thickness of a TV is not as essential as its height and width. But still, you should be aware of the thickness of the TV as well.

The depth or thickness of the TV depends on the hardware instead of the diagonal distance. The important thing is that the TV should be thick enough to carry all the hardware, like connectors, CPUs, and HDMI parts.

Anyway, modern TVs are 2 inches (5 cm) thick. The thickness may vary according to the TV model. But they generally vary from 1.7 to 2.2 inches. Remember to consider the stand thickness, around 12 inches (30.5 cm).

Are Bigger TVs worse quality? 

It depends on the number of pixels and the size of the TV. Suppose a TV has a large screen, but its resolution is shallow (720 or 1080) or the number of pixels or less. It will have worse picture/display quality. In contrast, if a TV has a bigger size but has a high resolution (4K or 8K), that means high pixels, its picture quality will be better. 


We should consider the right size to buy before we select a new TV for our new room or hall. Similarly, if you buy a 55-inch TV, you need to know the exact size of the TV.

So, a 55-inch TV is 48 inches wide, 27 inches long, and 2 inches deep or thick. Sometimes, you also have to consider the stand. I hope now you can select the exact size of TV you need.
