TV dimensions quick answer

TV size chart in inches and centimeters
The dimensions below assume the common 16:9 aspect ratio used by most modern TVs. Actual outer dimensions can be slightly larger because bezels, stands, and speakers vary by model.

How to calculate TV width and height
For a 16:9 TV, the diagonal, width, and height form a right triangle. The calculator uses the diagonal and the 16:9 ratio to estimate the screen width, height, and area without measuring manually.
This is why two TVs that differ by only 10 inches diagonally can feel much more different in a room. Moving from 65 to 75 inches adds roughly 15% more width and about one third more screen area.
65 inch vs 85 inch TV dimensions
The 65 inch and 85 inch sizes are popular because they sit on opposite sides of the living-room decision. A 65 inch TV is still manageable for many apartments. An 85 inch TV is a clear home-theater choice and needs more wall width, seating distance, and delivery planning.
- 65 inch TV dimensions: screen width about 56.7" (143.9 cm), height 31.9" (80.9 cm).
- 85 inch TV dimensions: screen width about 74.1" (188.2 cm), height 41.7" (105.8 cm).

What to check before buying
Before choosing a TV, measure the usable wall or cabinet width, check stand depth, confirm the viewing distance, and compare the next size up. The best TV size is the one that fits the room after the excitement of buying it has worn off.
