HDTV buying guide: which size should you buy?
Sponsored Links
High definition LCD TVs are almost always wide-screen nowadays. For wide screen HD LCD TV, you can sit much closer than regular TV. If your room is small, a 32 inch LCD will be good enough. On the other hand, you should buy a bigger one such as 42 inch LCD for your large living room or family room. 1080 TV, or 1920 x 1080 LCD TV is highly recommended. There is an easy formula to calculate the size of LCD TV:
- the minimum size = Viewing distance/3
- the maximum size = viewing distance / 1.5
The ideal viewing distances are as follows:
| HDTV diagonal screen size in inch | Mini viewing range in feet | Max viewing range in feet |
|---|---|---|
| 26 | 3.3 | 5.6 |
| 30 | 3.8 | 7.6 |
| 34 | 4.3 | 8.5 |
| 42 | 5.3 | 10.5 |
| 47 | 5.9 | 11.8 |
| 50 | 6.3 | 12.5 |
| 55 | 6.9 | 12.8 |
| 60 | 7.5 | 15 |
