If you don't own one already, or you need a new and improved TV for your new home, you may be tempted to purchase a widescreen digital television to enjoy your favourite movies, shows and sports programs. However, it can be difficult to select the right screen size, especially if you've been accustomed to viewing a TV with a traditional 4:3 screen. When it comes to size, there are many factors that come into play, such as screen resolution and personal preference. However, the last thing you want is to purchase an HDTV that is too small for the room, or so big that it dominates the space. Here's a tip: The rule of thumb is to take the distance you'll be sitting from the television and multiple by five to get the screen size you need. So if you'll be sitting eight feet away, you'll want to look at HDTVs with screens that are in the 35- 45 inch range. A good electronics dealer can help you make the best choice.

And remember to test out how high the TV will be.  Although most of us think it is best to place up high - usually right over the fireplace - it can be uncomfortable for your neck  over the long term.
