How to Calculate Square Inches for a Widescreen TV
- 1). Measure from the left of the screen to the right of the screen in inches. For example, assume a television measures 48 inches. This is the length.
- 2). Measure from the bottom of the screen to the top of the screen. In the example, assume it measures 28 inches. This is the height.
- 3). Multiply the length by the height to calculate square inches. In the example, 48 inches times 28 inches equals 1,344 square inches.
