The formula to calculate the TV Viewing Distance (Dtv) is:
\[ Dtv = \frac{TVs \times 2}{12} \]
where \( Dtv \) is the TV viewing distance in feet, and \( TVs \) is the total TV size in inches.
TV viewing distance is the optimal distance from which you should watch your TV to get the best viewing experience. It is calculated based on the size of the TV screen, ensuring that you are neither too close nor too far from the screen.
Let's assume we have the following value:
Step 1: Multiply the TV size by 2:
\[ 60 \times 2 = 120 \]
Step 2: Divide by 12 to convert to feet:
\[ \frac{120}{12} = 10 \]
Therefore, the TV Viewing Distance (Dtv) is \( Dtv = 10 \) feet.
