How many lumens does a projector need for legibility in a lighted room?

I have to give a presentation at a satellite office that requires either a train or airline trip, and I want to just use my tablet with a portable projector. How bright (lumens) does a projector need to be so it will be legible in a lighted room?

I think rcook12 has the right answer for this.

 Here is a chart on the lumens needed for various size screens at various distances. I would go with as bright as you can, it stinks trying to read washed out text during a powerpoint presentation, especially if it is one that is actually informative and not just “AV time.”.
