Have you ever wondered why your safety signs seem to not be doing their job? The reason might have something to do with improper viewing distances for your signs. The work it takes to identify where safety signs are appropriate and what their messaging should be, is all for nothing if people can’t properly view the sign itself. Following recommended safety sign viewing distance guidelines can ensure that people remain safe and aware of potential hazards.
The ANSI Z535-2007 standard uses a ratio of 25 ft of viewing distance per inch of text for “Favorable Reading Conditions.” For “Unfavorable Reading Conditions,” a ratio of 12 ft of viewing distance per inch of text is used. Determining what viewing distance you need for your safety signs can be dependent on many factors including:
- Type font
- Complexity of the message
- Visual acuity
- Reaction time necessary
- The angle the sign will be seen from
In addition, letter size on your safety signs may need to be larger for reasons including:
- To make the sign more noticeable from other information displayed in the area
- To enable legibility under low light, or other poor viewing conditions
- To alert persons sooner than the minimum safe viewing distance
- To convey special importance for portions of the message
- To improve legibility for persons who have vision problems
It’s easy to see that whatever message you are trying to convey on your safety signs, it’s important to consider how well people will be able to see and read your sign. SafetySign.com can help you keep people safe with properly designed safety signs. Order yours today!
