Ok I'm using Microsoft Word
I made a text box with the following:
2.12" high
3.37" wide
all internal margins are set at 0.05"

Font Settings:
Subscript selected
Arial Narrow
Size 11

Character Spacing Settings:
Spacing Condensed 0.1pt
Position Raised 1pt

Paragraph Settings:
Under the Spacing section Line spacing is set to Multiple at .53

This will make a card the size of a standard credit card with text a little bigger than the text on the back of a credit card.

That's what I'm using
