If you’re a person who likes to put the pen to the paper, there is a simple math formula you can use to calculate everything as well. If you don’t have a TV or screen picked out yet, you’ll need to measure the distance (in inches) from where the farthest seat will be placed, all the way to where you plan to put the TV/screen. Once you have the measurement, just plug it in to the following formula:
Screen Size = [Distance (inches)] / 1.6
As an example, if you had 10 feet (120 inches) of seating distance, you would need a TV or screen that is around 75 inches. Should you already have a TV / screen in place, I have a formula for you to help you calculate seating distance. Just take the size of your TV or screen (in inches) and plug it into the following formula.
