To measure a TV size, run a tape measure diagonally from one bottom corner of the screen to the opposite top corner, not including the plastic frame, and round to the nearest inch. That number is the size sellers use: a 65 inch TV measures 65 inches along the diagonal. Its width and height are smaller: a 65 inch 16:9 TV is about 56.7 inches wide and 31.9 inches tall before the frame. Use the chart below to check that a TV fits your stand, wall space or cabinet.

- TV size is the diagonal of the screen, corner to corner, not the frame.
- Width is about 87% of the diagonal and height about 49% for a 16:9 TV.
- Add the frame (bezel) and stand to the numbers if you are fitting a cabinet.
- Check the VESA pattern and weight before you buy a mount.
How do you measure a TV size?
- Turn the TV on so you can see where the picture area ends.
- Hook the tape measure on the bottom corner of the screen, inside the frame.
- Stretch it diagonally to the opposite top corner and read the number.
- Round to the nearest inch. That is the TV size. Measure width and height separately if you are fitting furniture.
If the TV is already boxed, the size is printed on the box and in the model number, where the first two digits are usually the size (for example, a 65 inch model often has “65” in its name).
What are the width and height of common TV sizes?
For a standard 16:9 TV, width is about 0.872 times the diagonal and height about 0.490 times the diagonal. These are screen measurements. Add the frame, usually a fraction of an inch to a couple of inches on each side, for the full width.
| TV size | Screen width | Screen height |
|---|---|---|
| 32 inch | 27.9 | 15.7 |
| 43 inch | 37.5 | 21.1 |
| 50 inch | 43.6 | 24.5 |
| 55 inch | 47.9 | 27.0 |
| 65 inch | 56.7 | 31.9 |
| 75 inch | 65.4 | 36.8 |
| 85 inch | 74.1 | 41.7 |
| 98 inch | 85.4 | 48.0 |
How do you check that a TV will fit?
| Where | Check |
|---|---|
| On a stand or console | The console must be wider than the TV’s feet spread, not only its screen. Read the stand dimensions in the spec sheet |
| On a wall | Leave a gap on each side and allow for the mount depth. See how high to mount a TV |
| In a cabinet or alcove | Add the frame, the stand and cables behind |
| In the room | Match the size to your seating distance. See the viewing distance chart |
