This chart outlines the quantity of BE balusters necessary to cross a span of the noted length. In some cases you may be cutting down a standard eight foot baluster rail to a shorter length. As an example, if you were to cut your rails to six feet, using the chart, you can see that a quantity of 10 balusters would be necessary to place between the newel posts, fiberglass columns or existing porch posts in order to meet the 4 inch ball code requirement of most States.
