fonts to use for 8x8 matrix

Using Arduino LEDs and Multiplexing
#1

While I am waiting for my PCBs from SeeedStudio for my 8x8 LED matrix.

I am trying to figure out what font and character spacing to use for my display.

I plan on chaining eight of the 8x8 together.

I have seen mostly 5x7 fonts such as 5x7 DOT Matrix | FontStruct.
So, do I leave the 3 remaining dots dark and start my next character on the next matrix?

Or should I consider having always two dark columns as space between the characters which can lead to a character spanning two matrices?

I hope that makes sense.

If you use any more that 1 line it will look weird.

Have a look at the Parola library and avoid all the pain, and also the articles I wrote on font handling in my blog (links below).
