How We Calculate TV Size

1

Measure your viewing distance

Measure the distance from your couch or seating area to where the TV will be mounted. Your distance is 20 feet.

2

Calculate the ideal size

For 20 feet, divide the distance in inches by 1.5. This gives you approximately 160 inches as the ideal diagonal screen size.

3

Consider the range

TVs between 120" and 200" will all work well at 20 feet. Go larger for immersive movies, smaller for casual viewing.

4

Choose your TV type

For a 160" TV, consider QLED/Mini-LED for bright rooms. Browse our recommendations below.

The Formula: Viewing Distance (in inches) ÷ 1.5 = Ideal TV Size

20 feet = 240 inches ÷ 1.5 = 160 inches
