Understanding TV & Video Calculations
TV Size
TV sizes are measured diagonally across the screen. This standard measurement helps compare different TV models consistently. The actual width and height can be calculated using the Pythagorean theorem, considering the TV's aspect ratio (typically 16:9).
Optimal Viewing Distance
The optimal viewing distance depends on your TV's size and resolution. For 4K TVs, you can sit closer than with 1080p TVs while still enjoying a crisp image. A general rule is to sit between 1.5 and 2.5 times the TV's diagonal screen size away from the display.
Resolution Impact
Higher resolutions (4K, 8K) allow you to sit closer to larger screens without seeing individual pixels. This creates a more immersive viewing experience while maintaining image clarity. Consider your room size and typical viewing habits when choosing a TV resolution.
