According to the Society of Motion Picture & Television Engineers (SMPTE) the recommended distances for viewing TVs are as follows.

Diagonal ....... SD ...... 720 ...... 1080
32" ...............8' ..........6' ..........4'
37" ...............10' ........7' ..........5'
42" ...............11' ........8' ..........5.5'
50" ...............13' ........10' .........6.5'

If you sit closer , you see pixelation ... If you sit further away you lose detail.
You can sit closer with the 1080 as there is more detail to see.

Apparently this is based on Visual Acuity , where the eye can resolve detail as small as 1.76mm at a distance of 20' assuming 20/20 vision.

I view my 32" set from about 10' to 13' (depending where I sit) and I'm happy with it ... I use an HDMI cable and the resolution is set to 720.

I wouldn't watch my set at only 6' ... Our viewing distance is chosen to suit our room layout as opposed to visual acuity ... A TV larger than 32" would totally dominate the room so is not an option.

This is probably why we don't notice any difference between Upscaled SD and the genuine HD at our normal viewing distance.
