What is an adequate LED panel resolution for a dynamic text application display?

The pitch depends on the viewing distance, generally 2ft-3ft per mm pitch is a good rule of thumb.  i.e. 10mm 20-30ft minimum viewing distance.

On the pixel matrix, you'll need 5x7 pixels per alphabet and the led modules are usually built in a array of 8x8, so a 4 line reader board for example will need to be 32 high and maybe 96 wide.
