How many inch LCD tv should I buy?

Ok. Many people will have this confusion on whether to buy a 32inch, 37inch, 42inch etc. If your viewing distance is 8 feet, go for 32 inch. If your viewing distance is 5 feet, go for 20 inch, if your viewing distance is 9 feet, go for 37 inch. If your viewing distance is 10 feet, got for 42 inch. These distances are good for 16:9 HDTVs.
Whats 16:9?...its an aspect ratio
Also viewing distance helps you when choosing between HD Ready and FullHD because if sit closer than your viewing distance, that is when you see a small difference.
Many people even cannot see that difference tough.
So depending on your viewing distance, you choose your TV.
A 32 inch is most commonly purchased TV.
I will use 32inch LCD TVs from LG, Sony and Samsung to compare in my later posts.
