Most televisions are sold by inch size, but that is not always the number you need in real life. When you want to know whether a TV fits on furniture, on a stand or in a certain spot in the room, width and height in centimetres are far more useful.
An inch size only tells you the screen diagonal. That is why it helps to convert the most common TV sizes into practical centimetre dimensions.
TV sizes in cm by inch size
| TV size | Diagonal | Width | Height |
|---|---|---|---|
| 32 inch | 81.3 cm | 70.8 cm | 39.8 cm |
| 43 inch | 109.2 cm | 95.2 cm | 53.5 cm |
| 50 inch | 127.0 cm | 110.7 cm | 62.3 cm |
| 55 inch | 139.7 cm | 121.8 cm | 68.5 cm |
| 65 inch | 165.1 cm | 143.9 cm | 80.9 cm |
| 75 inch | 190.5 cm | 166.0 cm | 93.4 cm |
These dimensions are practical screen measurements for a standard 16:9 TV. The outer frame and feet can still vary by brand and model.
What does that mean in practice?
A 55 inch TV is about 121.8 cm wide. A 65 inch TV is about 143.9 cm wide. That difference can completely change how a setup feels in your living room, so it is worth checking the real dimensions instead of relying on inch size alone.
Which size suits your room?
The right TV size depends on both available space and viewing distance. A screen that is too small can feel lost in a large room, while a screen that is too large can feel overwhelming if you sit close to it. Measure first, then compare sizes.

Do not forget VESA and placement
Width is not the only thing that matters. The VESA pattern, viewing height and the way the TV is placed all influence how practical the setup feels. Especially with larger screens, a TV stand can give you more flexibility than fixed wall placement.
Turn the right screen size into a cleaner setup
Once you know which TV size in centimetres fits best, the next step is making the setup look and feel right in the room. A good TV stand helps position the screen more neatly, manage the layout better and create a more balanced viewing height.
That makes the difference between a television that only fits on paper and a setup that actually feels polished in daily use.
Conclusion
If you are searching for TV size in cm, look beyond the inch label. The real width and height tell you much faster whether a screen actually suits your room and setup. Pair this with our guide on ideal viewing distance and our article about the VESA pattern for a better final choice.
