TV Viewing Distance Calculator

The Formula

The formula for calculating the optimal TV viewing distance is:

\[Viewing Distance (feet) = \frac{TV Size (inches) \times Factor}{12}\]

Where:

• TV Size: The diagonal size of the TV screen (in inches)
• Factor: A multiplier based on the TV's resolution

Factors for Different Resolutions

• 720p (HD): Factor = 2.5
• 1080p (Full HD): Factor = 1.8
• 4K (Ultra HD): Factor = 1.5
• 8K: Factor = 1.0

Calculation Steps

1. Determine the TV size in inches
2. Identify the TV's resolution and corresponding factor
3. Multiply the TV size by the factor
4. Divide the result by 12 to convert to feet

Example Calculation

Let's calculate the optimal viewing distance for a 55-inch 4K TV:

\[Viewing Distance = \frac{55 \times 1.5}{12} = 6.875 feet\]
