75 and 85 inch TV size in cm: width, height and the space you need
A 75-inch TV measures 166 × 93.4 cm and an 85-inch TV 188.2 × 105.8 cm. They look like a step up from 65 inches, but the screen area grows faster than the number suggests: a 75-inch TV has 1.9 times the area of a 55-inch one.
Dimensions of 75 and 85 inch TVs
Why the area grows so fast
Area depends on the square of the diagonal. An 85-inch screen has 2.4 times the area of a 55, and 1.28 times the area of a 75-inch screen. Going from 65 to 75 inches adds 33% more screen area, while the width grows by only 22 cm.
That is why large TVs feel much bigger in a room than a comparison of two diagonals suggests. It also means the wall and the furniture matter more.
How much wall and furniture you need
- Wall: at least 186 cm of clear width for a 75-inch TV and 208 cm for an 85-inch TV, which leaves about 10 cm each side.
- Stand or cabinet: at least 180 cm for 75 inches and 200 cm for 85 inches, then check the foot spacing in the manual. See how wide a TV stand needs to be.
- Height on a 50 cm stand: the top edge is about 143 cm for a 75 and 156 cm for an 85. On the wall, mounting height puts the center near 105 cm.
- Check the delivery path too. The box is wider than the screen, so measure doors, stairwells and the car before ordering.
How far to sit
An 85-inch TV needs about 2.6 to 3.5 m from the sofa. In a room where you sit 2.5 m away, a 75-inch TV is the better fit. The method is explained in TV viewing distance by size.
| TV size | Immersive, 40° (m) | Comfortable, 30° (m) |
|---|---|---|
| 65″ | 1.98 | 2.69 |
| 75″ | 2.28 | 3.1 |
| 85″ | 2.59 | 3.51 |
Is 75 or 85 right for you
Choose by distance, not by price. If you sit 3 m or more from the screen, 73 to 99 inches is the range the viewing angles support, so 75 and 85 inches both work. At 2 to 2.5 m, 65 or 75 inches is usually enough.
