The amount of bracing required is a function of the wind speed, the exposure, the story of the house, the spacing of the braced wall lines, and the bracing method used. In his training course, Foley teaches a method for calculating the required bracing length that he calls "Choose it, Adjust it, Compare it."

In the three examples below, we use Foley's method to find the required bracing for the first floor of the example house shown. Step 1: Locate the braced wall lines (BWLs) on the plans. Remember, BWLs do not have to line up with actual walls. In this example, BWL 1 accommodates a few walls that are all within the 4' maximum offset.
