Choosing the best fit TV Screen size for your Room
Why TV Screen Size Matters
TV screen size directly affects the following aspects:
- Viewing comfort and also eye strain
- Picture Immersiveness and clarity of display
- How well 4K or 8K resolution is utilized
- Overall room aesthetics
A properly sized TV allows your eyes to capture the full frame without having to go through excessive head movement while also maximizing the detail and sharpness of the pictures.
How is TV Screen Size Measured
TV size is measured diagonally. This means that it is measured from one corner of the screen to the opposite corner and is generally expressed in inches.
Take, for example:
- A 55-inch TV refers only to the screen, and this will not include the bezel or stand which comes with it
- An actual TV width and height vary by aspect ratio (usually in 16:9)
TV Screen Size Guide Based on Viewing Distance
One of the most reliable ways to choose a TV is by viewing distance. This is the distance between your seating position and the TV screen. Ideally, you should have a viewing distance of:
- For 4K smart TVs: 1-1.5 * screen size
- For Full HD TVs: 1.5- 2.5 * screen size
