Frequently asked questions

How is TV size measured?

TV size is the diagonal of the screen panel in inches — not including the bezel. A 52″ TV has a screen diagonal of 132 cm.

What are the exact dimensions of a 55″ TV?

A standard 16:9 TV at 55″ is approximately 121.8 cm wide and 68.6 cm tall (screen only). Add 2–5 cm per side for the bezel to get the full unit size.

How far should I sit from my TV?

The recommended range is 1.5× to 2.5× the screen diagonal. For 4K content you can sit at 1.5× — high pixel density means no visible pixels up close.

Does the advertised size include the stand?

No. The size shown is screen diagonal only. For shelf planning, check the manufacturer's spec sheet for total product dimensions including stand height.
