Just a little something… I was wondering how one would know the correct distance to keep. I looked up what font size one would be able to read from 6ft. This page gave me an answer. Of course this is a bit subjective. I ended up using Helvetic font, 16 pt. I could no longer read it at 4.5 ft - I have been using my ipad wayyyy too much. My husband however can still read this at 6 ft, although it took a little effort.
