A television is a common electronic device found in every household. However, not everyone knows how to select the right TV size for their room. If the TV screen is too large or too small for the installation space, it can affect the viewing experience. So, how many inches should you buy for the most suitable TV? In this article, Mytour will provide answers. Let's dive in!
1. What Size TV Should You Buy?
Televisions on the market come in various sizes. The decision on how many inches to buy depends on the layout of your TV setup and fits the room while maintaining a suitable and safe viewing distance.
Here are the sizes of TVs available today:
- A 32-inch TV is a relatively small size, usually equipped with HD or Full HD resolution by manufacturers. With this size, a 32-inch TV is suitable for rooms with an area under 10m2.

2. What is the Ideal TV Viewing Distance?
The distance from the TV screen to the viewing position is also a criterion to consider when choosing the appropriate TV screen size.

For larger TVs, the viewing distance should be greater. The screen size is measured in inches, where 1 inch = 2.54 cm, so the formula is as follows:
- Minimum distance (cm) = 2.54 x 2 x Screen size (inches)
- Maximum distance (cm) = 2.54 x 3 x Screen size (inches)
For instance, if you need to buy a 55-inch TV, using our formula, you can calculate:
Minimum distance = 55 x 2.54 x 2 = 279.40 cm = approximately 2.8 m.
Maximum distance = 55 x 2.54 x 3 = 419.10 cm = approximately 4.2 m.
So the suitable distance for a 55-inch TV is from 2.8m to 4.2m.
