Know a scale of readability font vs. screen size vs. # feet away?

[Kathm]

Hi,
We're doing a PowerPoint presentation that will be displayed on a 50"
screen. My manager says that there's a scale that allows one to calculate
font size vs. screen size vs. distance from screen. Has anyone heard of this?

Thank you in advance!

I'll end up dating myself but as a quick and dirty test we always used

to throw the transparency (yes! thermofax) on the floor and look at it
while standing up. If it was legible then it passed. Of course this
assumes that your presentation screen scales with the size of the room.

I still do this today with printouts.

I go to show mode on the monitor, and stand in the back of my office, about
eight feet from the screen. Same idea.
