70 Inch TV Dimensions: Width, Height & Viewing Distance
70″ TV = 61″ × 34.3″
A 70-inch TV has a screen about 61 inches wide and 34.3 inches tall (155 × 87.2 cm).
Step by step
- For 16:9, width = diagonal × 16 ÷ √(16² + 9²) = 70 × 0.8716 = 61.01 in.
- Height = diagonal × 9 ÷ √337 = 70 × 0.4903 = 34.32 in.
- Add about 1–3 inches each way for the frame and stand.
70-inch TVs suit large living rooms and home theaters; check that it fits wall space and doorways, and that the stand or mount is rated for its weight. A 70″ screen has 162% 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.
