TV Sizes: How to Choose the Perfect Size for Your Home

Most TVs have a standard aspect ratio of 16:9. This format is common in high-definition and ultra-high-definition models. With this ratio, you can easily calculate the exact width and height measurements of a TV using the diagonal inches. For example, a 55-inch TV has a width of approximately 121 cm and a height of 68 cm. It is important to have these measurements clear so you know if it will fit in the desired location.

Viewing distance is another key factor when choosing a TV. The general recommendation is that the distance between the TV and where you sit to watch should be between 1.5 and 2.5 times the diagonal of the screen. This ensures that you can enjoy the best picture quality without losing detail. For a 40-inch TV, the ideal distance would be approximately 2 metres.

When choosing a TV, it is also helpful to convert measurements from inches to centimeters for better reference, especially if space is limited. Here is a table with the most common measurements:

These are the standard dimensions for flat screen TVs with a 16:9 aspect ratio. However, some models may vary slightly in size depending on the brand and design.

• Small room: For small spaces, such as a bedroom or kitchen, sizes between 24 and 32 inches are recommended.
• Medium sized living room: In larger living rooms, TVs between 40 and 55 inches offer an ideal balance between size and viewing comfort.
• Large living rooms or home cinema: If you have a large space, TVs 65 inches or larger can provide a cinematic experience at home.

In addition to the TV’s dimensions, it’s important to consider the type of content you watch. If you enjoy HD movies or play 4K video games, large TVs will be the best option to get the most out of the image quality.

There are other aspects you should take into account when purchasing a television:

• Resolution: Full HD (1080p) TVs are still popular, but if you’re looking for the ultimate in picture quality, 4K and 8K models offer much higher resolution and are ideal for large screens.
• Display Technology: Nowadays, you can choose between LED, OLED and QLED TVs. Each technology has its own advantages, such as the better contrast in OLED or the longer lifespan of LEDs.
• Smart TV: Most modern TVs come with built-in Smart TV capabilities. This allows you to access streaming apps, internet browsing and much more without the need for additional devices.

When selecting a TV, make sure its technology and features fit your specific needs.

In general, larger TVs tend to consume more energy, although this also depends on the display technology. OLED models, for example, are more efficient than traditional LCDs.

If you plan to mount your TV on a wall, it is recommended to use a mount that is compatible with the size and weight of the device. Check the manufacturer’s specifications to ensure you choose the right mount.

Yes, while a larger TV can offer an immersive viewing experience, it could also increase eye strain if you are too close to the screen or if the lighting in the room is inadequate. It is important to adjust the distance and ambient light to avoid this problem.

The television measurements not only affect the physical appearance of the device, but also the viewing experience. When selecting the right size for your space, be sure to consider both the dimensions and the recommended viewing distance.
