personally, I wouldn't do more that 50" for being 16 feet away, however everyone has different eyesight. Talk to some friends and ask to see theirs, decide for yourself. Looking at TVs at best buy is dumb. When viewing them don't stand close try to get to your 16 foot sweet spot you will be viewing. But look at a TV with HD cable hooked up for a realistic picture quality. All TVs look great with a 1080p blueray showing on them.
