58 Inch TV Dimensions: Width, Height & Viewing Distance
58″ TV = 50.6″ × 28.4″
A 58-inch TV has a screen about 50.6 inches wide and 28.4 inches tall (128.4 × 72.2 cm).
Step by step
- For 16:9, width = diagonal × 16 ÷ √(16² + 9²) = 58 × 0.8716 = 50.55 in.
- Height = diagonal × 9 ÷ √337 = 58 × 0.4903 = 28.44 in.
- Add about 1–3 inches each way for the frame and stand.
58-inch TVs are the most popular living-room size in the US, best from about 5–7 ft away. A 58″ screen has 111% of the area of a 55″ TV.

How it works
TV sizes are the diagonal of the visible screen, not the width. Because almost all TVs are 16:9, width and height follow directly from the diagonal. Screen area grows with the square of the size, so a 75-inch TV has nearly twice the picture of a 55-inch. Manufacturers list exact dimensions with and without the stand — check them before buying furniture or a wall mount.
