TV dimensions in cm are easy to work out: a 16:9 screen is about 2.21 cm wide and 1.25 cm tall for every inch of its size. So a 43 inch TV’s screen is about 95 cm wide and 54 cm tall, and a 55 inch is about 122 × 69 cm. The TV body is a little bigger, and the stand adds height.
How TV size is measured (the diagonal)
The inch number on the box is the diagonal of the screen, from one corner to the opposite corner. It is not the width, and it does not include the frame (bezel).
To calculate TV dimensions yourself for any 16:9 TV:
- Width (cm) = inches × 2.21
- Height (cm) = inches × 1.25
Almost every modern TV is 16:9, so this works for all mainstream brands.
Width and height table, 32 to 85 inches
Screen size only (the picture area):
| Size | Width | Height |
|---|---|---|
| 32″ | 71 cm | 40 cm |
| 40″ | 89 cm | 50 cm |
| 43″ | 95 cm | 54 cm |
| 50″ | 111 cm | 62 cm |
| 55″ | 122 cm | 69 cm |
| 58″ | 128 cm | 72 cm |
| 65″ | 144 cm | 81 cm |
| 70″ | 155 cm | 87 cm |
| 75″ | 166 cm | 93 cm |
| 85″ | 188 cm | 106 cm |
A 65 inch TV is about 1.44 m across, and an 85 inch is nearly 1.9 m, wider than many sofas.
Add the bezel and stand: real-world space needed
The table is the screen. The actual TV is bigger:
- Frame: modern slim TVs add roughly 1–3 cm to the width and height. Older or budget sets can add more.
- Stand or feet: usually add 5–10 cm of height. Feet often sit near the outer edges, so your cabinet top may need to be almost as wide as the TV itself.
- Depth: the body is only a few centimetres deep, but feet often need 20–30 cm of cabinet depth.
Always check “dimensions with stand” on the spec sheet for the exact model. Retailers and brand websites list it in millimetres.
If the TV is going on the wall, the 55 inch example takes up about 123 × 71 cm. See how high to mount a TV for where to put it.
How to measure your wall unit correctly
Many Kenyan wall units and TV cabinets were built for 32 to 50 inch sets, so measure before you pay or book delivery.
- Measure the opening width inside the unit, not the outside.
- Measure the height from the shelf to the shelf or panel above.
- Measure shelf depth where the feet will stand.
- Leave 5 cm or more on each side for air flow and to reach the cables.
- Check the feet position. If they sit at the edges, they may hang off a narrow shelf; ask whether the model has a centre stand or adjustable feet.
- Measure doorways and corridors for a very large set still in its box.
Size isn’t only about fit. Use the viewing distance chart to check it suits your seat, and how to choose a TV for the rest.
