Viewing distance is one of the most important factors needed to determine the correct size of the LED Display.
As a general rule: 1 inch of text is viewable up to 50 feet away 1 or 25mm of text is viewable up to 15m away . The following diagram illustrates at what distance a specific character size of the content on an electronic sign will be recognized and understood by a stationary audience.
However, if the target audience is moving, then another factor, TIME, is required. Based on our experience and research, an average of at least three to four seconds is required for a moving audience to adequately recognize and comprehend six to eight grouping of content on an electronic sign. For example, an audience will have three seconds or less to view LED Display signs with four inches of text. If the LED Display signs have too much content, then the reader will not have sufficient time to comprehend the entire content.
