Cocco said:is there a better way to duplicate it on the page so that the other nine sizes appear neatly?
you can make each business card a single page in draw, the size of 1 card
you can do a print range of 1-10 for the first side of sheet, and adjust print order for the back using imposition in print preview
Here is 4 cards only
70mm x 40mm....
The standard around the world is around 3.5" x 2" or 89mm x 51mm.
