Minimum is where you can see all of the TV in full focus without needing to move your eyes, head or neck.
Maximum there is no such thing. You can sit as far away as you would like to.
Also charts which measure distances to tv size don't have any science behind them.
When I go to the opticians for an eye test. I can see the smallest letters on the wall. Others won't be able to. I have better than 20/20 vision apparently is what optician told me.
So I could sit further away than someone who has bad eyesight.
So don't listen to any chart.
