Why Should you Trust Me? Hi, I am Anirban Saha, an Engineer with a Specialization in Electronics and Communication Engineering. I have experience in Smart TVs, Electronics circuits, and Computer peripherals.

Let’s get started!

Dimensions of a 55-Inch TV

Measuring using a Measuring tape, the dimensions of a 55-inch TV with a 16:9 Aspect ratio comes to 47.9” wide and 27” in height.

From TV to TV this dimension varies about a few inches due to the presence of bezels on their sides and a stand on the bottom. The measurement without a stand and with a stand would differ.

Similarly, with a bezel, the measurement will increase.

Here the measurements are only considering the Screen and not the bezel or the TV stand.

Here is the process of me measuring the height of a 55-inch TV.

How Wide is a 55-inch TV?

A 55-inch TV is 47.9 inches wide considering the TV has a 16:9 aspect ratio.  

The width of a 55-inch TV may vary up to 1-2 inches based on the width of the bezel used on your TV. The measurement above is the exact measurement without considering any bezel on the TV.

So, if you need to place it on a Table, it should be at least 56 inches, considering 3 inches gap on either side. We need to consider that due to the bezel space for your TV.

Is 55-inch too Big for a TV?

A 55-inch TV is much bigger than a regular TV. However, considering we are more getting used to bigger sized screens, it is now a good size to consider for a TV at your Home.

If you are not used to bigger-sized TVs like at least 40 inches, you may feel this size of a TV is a big one. So, it is not for all. But, it is definitely for the people who want to have a bigger screen for Entertainment and a more immersive experience.

To be sure whether this sized TV would be suitable for your room, you can check whether your viewing location and your TV have a distance of 7.5 ft.

How Far Should you sit from a 55-inch TV?

To watch a 55-inch TV, the optimal distance is to sit between 5.5 ft to 7.5 ft from the TV. The Field of View would be between 30 degrees and 40 degrees.

This Field of View is said to be optimal for viewing TVs. Field View is important to negate the factor of visual fatigue while watching TV for a longer duration.

If you view 55-inch TV at a distance lesser than 5.5ft, you may not feel natural as the Field of view will get to >40 degrees.

You can size further than 7.5 feet but that is fine as per your convenience.

How is TV Size Measured?

The TV Size is measured in terms of its diagonal measurement from one corner to another corner.

The TV’s size remains the same across different brands considering they provide the TV at a 16:9 aspect ratio.

It can only vary a little considering the additional size of the Bezel that covers the outside part of your TV screen.

Science to Know to Choose the Right Size of TV

When you choose a TV for your home, it’s good to know the right size that would fit the space.

Here are the things you should know that would help you to know if this TV size is the right fit for you:

Knowing The Field of View

The Field of view is the area your Eye can scan comfortably while looking. As the recommended field of view measurement, 30 degrees to a max of 40 degrees is comfortable to watch TV.

So, the bigger your TV is, you need to sit at a further distance for a comfortable viewing experience. The distance can be measured by the field of View.

Check the Rooms size and especially where you will sit to watch the TV and then calculate the distance from the area where the TV with be installed. Now, you will get a good idea.

If you see the distance is about 5.5-7.5 ft, the 55-inch TV is suitable.

However, if you see the length is lesser, which may be due to a smaller room, then you can even try going for smaller sized TV. In case you are interested in a smaller-sized TV, you can check this 40-inch TV dimensions guide written by me.

Knowing the Bezel Thickness

If your TV has a thicker bezel it may appear to be bigger. However, to get an immersive viewing experience going with the as much lesser bezel as possible is recommended.

Modern TVs come with a very thin bezel and they don’t take up any additional space than the TV’s screen size. In case you are mounting the TV on a Cabinet, you need to take some space for the bezel and then calculate the size.


Let’s conclude the post on the 55-inch TV dimension!

So, now you got an informed decision about your TV’s size and hope you will be now good to decide on the right size for your TV.
