At SGS, we're all about ways to Get Noticed! And we really mean it. A big piece of this is the size of your lettering. Think about the environment of your sign. Is it intended for people walking by? Or cars zooming by? If traffic passes your business quickly - lean toward the "Best Impact" end of the range. But if you attract pedestrians, customers will have more time to focus on your message even at a further distance.
We also have a color contrast chart. Oh yeah, we're serious when we say we can help you Get Noticed.
