When you’re in the market for a new TV, it’s fun to compare the best brands to each other or decide on what specs you are wanting. But what about when it comes time to think about the more intimate details of your future television?
When considering a 55-inch TV, the average dimensions are 47.9 inches wide, 27 inches tall, by 2 inches thick. For those of you out there who operate with the metric system, this comes out to an average of 121.7 centimeters wide by 68.6 centimeters tall, and 5 centimeters thick.

Whether you are envisioning your new TV mounted to your wall, or peacefully sitting atop your entertainment stand, knowing the real dimensions of your TV is important to make sure that you can truly enjoy your newest form of entertainment.
This is where it gets tricky, however: the dimensions of 55-inch TVs can vary throughout the market, due to anything from the brand to the size of the trim around the TV.
TV Model and Manufacturer | Dimensions (in) (W x H x D) | Dimensions (cm) (W x H x D) |
Samsung QN90A Neo QLED | 48.3 x 27.8 x 1 | 122.7 x 70.6 x 2.5 |
LG C1 OLED | 48.3 x 27.8 x 1.8 | 122.7 x 70.6 x 4.6 |
TCL 6-Series Roku TV | 48.3 x 28.1 x 2.8 | 122.7 x 71.4 x 7.1 |
Sony Bravia XR A80J OLED | 48.4 x 28.1 x 2.1 | 123 x 71.4 x 5.3 |
Hisense U8G Android TV | 48.5 x 28.2 x 3.9 | 123.2 x 71.6 x 9.9 |
Wait, All 55-Inch TVs Don’t Have The Same Dimensions?
Maybe it sounds a little ridiculous, but it’s true – each type or model of a 55-inch TV doesn’t necessarily have the same dimensions. This can be due to anything from the manufacturer or the brand, to the type of TV trim.
Nothing is worse than forking over massive amounts of money for a brand-new television, just to have the dimensions not be what you thought.
So, let’s break it down so it’s a bit easier to understand.
When it comes to dimensions, there are three measurements you should be concerned with; height, width, and depth or thickness.
- The height is how tall the TV is. The overall height of your TV will be taller if you have a taller TV stand. You can still opt to change the TV stand yourself to a shorter/taller option if you really want, but this is something to still keep in mind.
- width is how wide or far across horizontally the TV is.
- And the depth or thickness is how far back the TV will go. Nowadays, TVs are thinner than ever, hence the name flat-screen TV. But especially if you are wanting a wall-mounted TV in a cramped room, keep the TV depth in mind.
So What Is The 55-inches Really Measuring?
When we say a 55-inch TV, what we’re talking about is the distance diagonally across the TV screen. This means that any given 55-inch TV can have varying dimensions of height, width, and depth but it will still have a consistent 55-inch measurement from opposite corner to opposite corner.
One last piece of general information about TVs when you’re considering their dimensions is that modern TVs typically have an aspect ratio of 16:9.
The Real Dimensions of 55-inch TVs
Since the diagonal is always the largest measurement for a TV (or for any rectangle for that matter), the screen dimensions of the individual width, height, and depth will always be less than 55 inches.
And because the standard aspect ratio of modern televisions is pretty standard sitting at 16:9, we can conclude that if a TV has a smaller width, it will also have a smaller height, and vice versa for a larger height/width.
Popular 55-inch TV’s Dimensions
Now, before we start making you feel like you’re back in high school math class with us throwing all these numbers at you, we’ll just lay it out so it’s easy to understand.
The most common 55-inch TVs come from brands like Samsung, Sony, and LG. Check out this chart below for the dimensions of 2022’s most popular 55-inch TVs.


For example, the TCL 4-Series Roku TV is a 55-inch television, therefore it has a 55-inch diagonal measurement, and its dimensions itself are 48.3 x 28 x 3.2 inches (122.7 x 71.1 x 8.1 cm).

However, don’t forget that the stand adds additional height to the TV if it is not wall-mounted. In the case of the TCL 4-Series Roku TV, the height for the screen may be 28 in (71.1 cm), but with the included TV stand the overall height for the TV increases to 30.6 inches (77.7 cm).
Though the screen dimensions of many standard 55-inch televisions don’t substantially deviate from each other, it’s important to remember that each TV is created differently with unique features.
Ideal Viewing Distance
Did you know that there is an ideal viewing distance for each TV type? The ideal viewing distance for a 55-inch TV is around 7 to 8 feet. Of course, this can also be affected by personal preference – feel free to just experiment with different distances until you find which one is most comfortable for you!
How The TV Frame Affects Dimensions
If you’re in the market for a new TV, typically the major component you’re focused on is the screen. I mean, this is what you’re buying the TV for, right? However, many times people forget about the frame or the trim on the television they want to buy.

The TV frame or trim is usually pretty thin, especially on newer televisions, but don’t forget that it still accounts for a small portion of the TV’s overall size that the manufacturer’s dimensions don’t take into account
Trending Features For 55-inch TVs
It’s no secret that nowadays, for tech and electronics especially, innovation is at the forefront of our minds. High-quality televisions are now a standard in every household, and each year there are new features available on the market to choose from.
4K Resolution
4K resolution is becoming increasingly popular on televisions to provide a high level of video quality. 4K resolution essentially means that there are around 4,000 pixels in each row of pixels running horizontally along the television screen. The high-definition resolution of 4K is four times greater than that of 1080p.
Smart TVs
We’ve been moving away from cable television as a society for a while. Streaming services like Netflix and Hulu have been gaining substantial popularity as one of the world’s top forms of entertainment. Smart TVs allow users to watch their choice of content directly through their TV from any number of streaming services, without the need for cable television or other means.
Additional Features
Modern televisions provide more than just pure entertainment. There is a wide variety of features available on the market for modern TVs, including;
- HDR (high dynamic range), which increases both the picture’s range of color and contrast, as well as
- OLED (organic light-emitting diodes), provides another level of amazing picture quality.
It’s no surprise that over the years, the evolution of the average household television has evolved immensely. When you’re looking for your next TV, make sure to not overlook the amazing features that are now commonplace in the market!
Bringing Your TV Home
If you’re expecting to haul your new TV home in a small sedan, sorry to break it to you, but that won’t cut it. Most 55-inch TVs won’t even fit into an average or midsize SUV.
Because televisions are securely packaged in boxes when you buy them, it will take up much more room in your car than you expect. Your best bet to take your TV home is with a larger SUV, such as a Honda CRV or a Nissan Rogue.
Some good tip for transporting a new TV is to place it vertically in your car to reduce the risk of a damaged screen. Also, ensure it is properly secured to avoid the possibility of it shifting during transit.
TV Stands Versus Mounts
So, you finally got your brand-new 55-inch TV! Now it’s time to maximize your television enjoyment by properly placing it in your home.
Depending on your home space, you can either use a television stand to place your TV upright on any flat surface, or you can mount it to the wall.
When wall-mounting your TV, it’s vital to make sure it is properly and securely installed to prevent any damage to either your home or your television.
Enjoy Your 55-inch TV The Right Way
When it comes down to it, there are many factors to take into consideration if you are looking for a new 55-inch television. Accounting for the accurate and true dimensions of a 55-inch TV is important to ensure that you can truly enjoy your newest piece of entertainment to the fullest extent.
