One advantage of the smaller booklet is that it is more convenient for the recipients to put into their pockets or handbags; but if it is too small it is more likely to be overlooked and the type may have to be crowded. The mailing weight of the booklet must be considered in determining the size. If it goes over two ounces, it cannot be sent by third-class permit mail. These are problems that a printer can give good advice on.
