How to measure
TV screen size？
Calculating your TV size is less complicated than you might think. A TV's size refers to its diagonal length, which comes from measuring from the upper left hand corner of the actual TV screen to the lower right hand corner. Most are expressed in cm.
Rule of thumb:
bigger is better
TVs come in various sizes, but we recommend selecting the largest size your budget allows. If you're considering getting a TV that's 1m 89cm (75") or more, there's something you should know. According to Samsung Internal Research, a major reason for purchasing new TVs is the demand for bigger screens. And that even after purchase, satisfaction remains very high. So, has there been a particular screen size that's been on your mind? Then, now's the time to go big and never look back.
1. Check the actual TV dimensions.
The excitement of buying a new TV can often cause you to forget about the actual task of setting it up. A TV is more than just its screen size. The physical dimensions of a big screen TV, stand and bezel included, as well as its future placement in the room are all important factors to remember. Be sure to compare the exact TV dimensions with your furniture setup to avoid headaches down the road when setting up your big screen TV.
2. Check the TV resolution, especially with a big screen TV.
The general rule of thumb is that as the screen size increases, so should the total pixel count or resolution. The better the resolution, the more you see the image instead of the pixels. This is why when you buy a big screen TV it is highly recommended to go with a high resolution picture quality like 4K.
