John wrote an excellent posting about ISO paper sizes. However he made one slight error. >if you did need to know, you can easily >calculate any of the sizes from the simple area formula: A=LxW.

He should have written "Dividing each of these dimensions by 2**A-numkber gives the length and width of that A-size".
