Shopping for a new 55-inch television? Whether you’re placing it on a TV stand, mounting it on a wall, or positioning it within a cabinet, knowing the exact dimensions ensures a seamless fit. Consider that the measurement indicates the diagonal length of the screen, not the actual width or height. So, you might be wondering, how wide are 55-inch TVs? This TV size guide explains the true width of a 55-inch TV, along with factors that affect its size and important considerations for placement and viewing distance.
What are the dimensions of a 55-inch TV?
TV screen sizes are measured diagonally, from one corner to the opposite corner. This means that a 55-inch TV does not have a width of 55 inches—it’s actually smaller. On average, a 55-inch TV has a width of approximately 47.9 inches (121.7 cm).
However, the width can vary slightly depending on the model and brand (which you’ll read more about in the next section).
The table below gives you a general idea of the approximate dimensions of a 55″ TV. However, note that it’s important to check the specifications of the specific model you’re considering.
| Dimensions | Approximate size |
| Width | 47.9 inches (121.7 cm) |
| Height | 27 inches (68.6 cm) |
| Depth | 2-4 inches (varies by model) |
Factors that affect the actual width of a 55-inch TV
There are a few factors that affect the actual TV width. Design style and bezel thickness are just a couple of examples that can cause slight variations, even among TVs with the same size classification. Different manufacturers may prioritize different features, leading to varying dimensions. Here a couple of things you should know:
- TV bezels: Older TVs often had thick bezels (the frame around the screen), but newer models are designed with ultra-thin or even bezel-less screens. TVs with thicker bezels will be slightly wider than those with a slim design.
- Model variations: Different brands have different design approaches, which means two 55-inch TVs from separate manufacturers may not have the exact same width. Some premium models prioritize a sleeker, more compact build, while budget-friendly options might have slightly larger frames.
Remember to consider the bezel size and model variations as these factors affect the overall dimensions and viewing experience.

Ideal viewing distance for a 55-inch TV
Your seating distance plays a huge role in how immersive and comfortable your viewing experience is. For a 55-inch TV, the ideal viewing distance is around 7 to 10 feet (2.1 to 3 metres). Consider the size of your room in relation to the TV’s screen size and specifications, as larger TVs may require more space for optimal viewing. Additionally, your personal preferences should influence how far back you sit to achieve the best experience.
A good viewing distance enhances picture quality, prevents eye fatigue, and allows you to fully appreciate the details of your favourite shows and movies. Here are a few factors that can impact your ideal viewing distance:
Room size
Ensure your space allows for the correct distance. If your living room or entertainment area is small, you may need to consider whether the recommended viewing distance can be maintained. Sitting too close to a large screen can lead to discomfort, while sitting too far may reduce the immersive effect of the display.
TV resolution
Check your TV resolution. 4K models let you sit closer without losing clarity. Because they have a higher pixel density, you can enjoy a more detailed image, even at shorter distances. In contrast, lower-resolution TVs like 1080p require a bit more space between you and the screen to avoid seeing individual pixels.
Understanding the recommended distances based on your TV size and resolution enhances the overall viewing experience. How to calculate viewing distance based on TV resolution? Here are some guidelines:
- For 4K TVs: You can sit closer, around 4.5 to 7 feet (1.3 to 2.1 metres). Higher resolution reduces visible pixelation, allowing for a sharper and more immersive viewing experience without loss of detail.
- For 1080p HD TVs: A distance of 7 to 10 feet is recommended to avoid seeing individual pixels. 1080p HD TVs may appear less sharp when viewed up close, so sitting farther back helps maintain a smoother image and a more comfortable viewing experience.
Personal preference
How close would you like to be to the TV screen? Some people enjoy sitting closer for a more cinematic experience. If you’re a movie buff or a gamer, sitting closer can create an immersive feel, making you feel more engaged with the content. However, others may prefer a bit more distance to avoid eye strain, especially during long viewing sessions. Whatever you prefer, make sure you are comfortable.
What to consider when purchasing a 55-inch TV
When choosing a 55-inch TV, consider more than just its dimensions. Factors like screen resolution, smart features, audio quality, and mounting options can all impact your viewing experience.
Screen resolution
Screen resolution refers to the clarity and detail of images displayed on a screen, determined by the number of pixels it contains. It’s typically expressed as width by height (e.g., 1920×1080), where a higher resolution indicates more pixels, resulting in sharper and more vibrant visuals.
If you’re deciding between 4K Ultra HD and 1080p Full HD, consider this: 4K offers four times the resolution of 1080p, providing much sharper details and more vivid visuals. This is especially important if you sit close to the screen, as 4K minimizes visible pixelation and creates a more immersive experience. However, if you’re on a budget or mostly watch content that isn’t available in 4K, a 1080p TV still delivers excellent picture quality for everyday viewing.
Smart features
Consider TVs with smart features. They provide seamless access to streaming services, making it easier to enjoy a wide range of content without needing extra devices. This adds convenience and enhances your viewing experience.
Most TVs now come with built-in streaming apps like Netflix, Disney+, and Prime Video. Consider whether you need a voice assistant (Google Assistant, Alexa) or app compatibility. Some models also include smart home integration, allowing you to control other connected devices like lights or thermostats. Additionally, make sure your chosen TV supports software updates to keep up with evolving streaming services and features.
HDR and picture quality
High Dynamic Range (HDR) enhances colour and contrast, making images more vivid and realistic. Look for TVs with HDR10+ or Dolby Vision support. These technologies improve brightness levels and create a wider range of colours, making dark scenes clearer and bright scenes more lifelike. If you watch a lot of movies or play video games, HDR support can make a noticeable difference in overall picture quality.
Audio quality
While picture size is important, don’t overlook sound. Many 55-inch TVs have average built-in speakers, so consider adding a soundbar or surround sound system for a richer experience. Some TVs include advanced audio technologies like Dolby Atmos, which enhances sound depth and clarity. If you have a large room, external speakers or a soundbar can help fill the space with immersive audio, creating a true home theatre feel.
TV stand or wall mounting
When it comes to setting up your TV, you have two primary options: using a TV stand or wall mounting. Your choice will largely depend on the size of your room, its layout, and your personal preferences.
- TV stand: Ensure your stand is wide enough to support the TV’s width (about 48 inches). Look for a sturdy stand that can handle the TV’s weight and has space for additional devices like gaming consoles or streaming boxes.
- Wall mount: Check the TV’s VESA compatibility to ensure it fits your mounting bracket. A properly mounted TV not only saves space but also improves your viewing angle. Consider a tilting or full-motion mount if you need flexible positioning for different seating arrangements. More importantly, ensure that the wall is structurally sound and can support the weight of the TV.
