How wide is a 55 inch tv can be difficult to understand or imagine.
When I first went tv shopping, I was confused about the measurements.
A 55-inch screen sounds massive, but that number only tells part of the story.
The width of a 55-inch TV is around 48 inches or 122 centimeters. The size varies between different brands and models, which makes it important to understand the dimensions.
That 55-inch measurement refers to the screen’s diagonal length, not its width or height.
It’s the distance from one corner of the screen to the opposite corner.
The width, height, and depth of a TV helps you to know if it’ll fit on your wall, entertainment center, or wherever you put it.
55-inch TVs have become popular for modern homes because they’re big to create the best viewing experience but are not gigantic .
Here in this post, we’re going to break down everything you need to know about how wide is a 55 inch TV.
We’ll look at the measurements, compare different brands, and help you figure out how much space you need for it.
So, let’s go and find out the best one for your space.
How Wide is a 55 Inch Tv? Understand the Dimensions
A standard 55-inch TV isn’t 55 inches wide but that number refers to the diagonal screen measurement from corner to corner.
The width of a 55-inch TV is about 48 inches.
The height is around 27 inches, and the depth ranges from 2 to 3 inches depending on the model.
These measurements are for the screen, but some TVs have bezels that add a bit to the size.
Modern TVs have thin bezels that add less than half an inch to the width.
Here’s a table with all the measurements for a standard 55-inch TV:
| Dimension | Inches | Centimeters | Millimeters | Feet | Meters |
| Diagonal | 55 | 139.7 | 1397 | 4.58 | 1.397 |
| Width | 47.9 | 121.7 | 1217 | 3.99 | 1.217 |
| Height | 27 | 68.6 | 686 | 2.25 | 0.686 |
| Depth | 2-3 | 5-7.5 | 50-75 | 0.17-0.25 | 0.05-0.075 |
| Screen Area | 1,290 sq in | 8,334 sq cm | 833,400 sq mm | 8.9 sq ft | 0.83 sq m |
If you add a TV stand, the height will reach 29-30 inches.
The screen area is around 1,290 square inches or 8.9 square feet.
How much space is needed for a 55 inch TV?
Before you rush to buy a 55-inch TV, visualize your room.
I’ve seen many people get TVs that were big or small for their space, and it ruins the viewing experience.
For a 55-inch TV, you’ll want to consider:
- Wall space: You need at least 4 feet of wall width. I recommend having at least 3-4 inches of extra space on each side.
- Viewing distance: For a 4K 55-inch TV, the best spot for viewing is between 4.5 and 7 feet away. Any closer and you notice pixels or far and you’ll miss detail.
- Room layout: Consider the seating arrangement and whether everyone will have a good angle to view the screen.
- TV stand size: If you’re not wall-mounting, you’ll need a TV stand that’s at least 48 inches wide for proper support.
The wall space for a 55-inch TV should be 55-60 inches wide, which gives some breathing room on either side of the TV. This prevents the TV from looking cramped and creates a balanced look.
For TV stands, look for one that’s at least 50 inches wide with a depth of 15-18 inches. This gives your TV plenty of support and some extra space for other items like a soundbar or game console.
Many TV stands are designed specifically with 55-inch TVs in mind since they’re so popular!
Comparing 55 Inch Tv of Different Brands
Even though all 55-inch TVs have the same diagonal measurement, there can be small variations in the dimensions between brands.
Let’s look at some options:
TCL 55 Inch Tv
TCL has become popular for their budget-friendly TVs that don’t skimp on quality.
A TCL 55-inch TV has dimensions close to the standard:
- Width: 48.3 inches
- Height: 28 inches with stand, 27.1 inches without stand
- Thickness: 3.1 inches
- Weight: Around 28 pounds
From side to side, the TCL 55-inch TV measures over 48 inches.
What’s nice about TCL models is they tend to have thin bezels, which means you’re getting all screen and little frame.
Samsung 55 Inch Tv
Samsung is known for their sleek designs and cutting-edge display technology. The 55-inch TVs measure:
- Width: 48.3 inches
- Height: 27.8 inches without stand
- Thickness: 2.1 inches for LED models, as thin as 1.6 inches for QLED models
Samsung offers different display technologies that affect both the picture quality and the physical dimensions.
The LED models are the standard, while QLED offers better color and contrast.
The premium offering, OLED TVs, can be extra thin.
The difference between the technologies affects weight and mounting considerations.
QLED models are heavier than standard LED TVs but offer better brightness and color.
LG 55 Inch Tv
LG is a leader in OLED technology, which allows for some of the thinnest TVs on the market:
- Width: 48.3 inches
- Height: 27.8 inches without stand
- Thickness: Standard LED models are about 2.5 inches, while OLED models can be as thin as 1.8 inches
- Weight: Around 35 pounds for standard models, light for OLED
From side to side, LG 55-inch TVs measure around 48.3 inches, similar to other brands.
What sets LG apart is their ultra-thin designs, mainly in their OLED lineup.
55 Inch Tv Compared to Other Common Tv Sizes
If you are trying to decide between different TV sizes then here’s how a 55-inch TV stacks up against other popular options:
| TV Size (diagonal) | Width (inches) | Height (inches) | Screen Area (sq inches) | Best Viewing Distance |
| 43″ | 37.5 | 21.1 | 790 | 3.5-5.5 feet |
| 50″ | 43.6 | 24.5 | 1,068 | 4-6.5 feet |
| 55″ | 47.9 | 27.0 | 1,290 | 4.5-7 feet |
| 65″ | 56.7 | 31.9 | 1,809 | 5.5-8.5 feet |
| 75″ | 65.4 | 36.8 | 2,407 | 6.5-10 feet |
| 85″ | 74.1 | 41.7 | 3,089 | 7.5-12 feet |
Looking at this table, you can see that going from a 55-inch to a 65-inch TV gives you about 40% more screen area. It is a big difference.
On the other hand, downsizing from 55 to 50 inches only reduces your screen area by about 17%.
The viewing distance is important too. If you sit close to a big TV, you’ll be scanning the screen and may notice imperfections but far away, and you’ll miss the detail that makes 4K TVs worth buying.
Considerations You Should Remember Before Buying 55 inch TV
Finding the perfect TV isn’t only about knowing its width.
Here are some key things to think about before you buy:
Room Size and Viewing Distance: A 55-inch TV works best in medium-sized rooms where you’ll be sitting 4.5-7 feet from the screen. Measure the distance from your couch to where the TV is. If you’re sitting close, consider a small TV.
Mounting and Placement: If you’re wall-mounting, make sure your wall can support the TV’s weight. The center of the screen should be at eye level, which is about 42 inches from the floor. Leave 2-4 inches of space behind a wall-mounted TV for ventilation.
Resolution Matters: Nearly all 55-inch TVs today come with 4K resolution, but there’s a big difference in picture quality between budget and premium models.
Screen Technology: You’ve got options:
- Standard LED: Most affordable, good brightness
- QLED: Better color accuracy and brightness
- OLED: Best contrast with perfect blacks, but typically more expensive
Connectivity: How many HDMI ports do you need for your game console, cable box, streaming device, etc., many TVs come with 3-4 HDMI ports, but cheap models only have 2.
Smart Features: All modern TVs are “smart” with built-in apps, but the interface and available apps vary by brand. Some use Roku, others use Android TV, and Samsung has its own system.
