Ben breaks down Winning Campaign Signs into three steps: 1) Choose the number of campaign yard signs. See Link 2) Design yard signs that stand out and be consistent with branding using you sign as a logo and image of your campaign. Use contrasting colors that stand out and stay away from red, white and blue. 3. Choosing a size. Generally, if you have a long name you will need a slightly larger sign. Most yard signs are 24″ wide by 18″ high.
