To determine the cost of the advertisement, multiply the number of column inches by the newspaper's rate. So, if a newspaper charges $10 per column inch, the cost for the advertisement discussed above would be $180.00 (18 column inches multiplied by $10.00). Advertisements that span over more than one column also gain a small amount of extra space in between columns because they stretch across the gutters. Gutters are the empty space between columns. Gutters range from about 10 points to about 1 pica wide. In addition, most newspapers charge for an extra column if an advertisement is a double truck.
