The document discusses key factors in creating an effective sign, including visibility, readability, noticeability, and legibility. It notes that a sign should be sized appropriately for viewing distance, with 1 cm of letter height for every 1.2 meters of distance. Readability is increased by logically grouping ideas and using formatting like larger text. Noticeability can be improved by using color contrast, unique design elements, or motion. Legibility depends on clear typestyle selection without sacrificing readability. The document also provides guidance on character height, width-to-height ratio, spacing, and using high color contrast materials to optimize a sign.
3. The sign should be sized appropriately for the viewing
distance. Generally, you will need 1 cm of letter height
for every 1.2 meters of viewing distance. The sign
should also be placed in a location with maximum
exposure to the target audience.
Visibility
4. The sign should be organized in a manner that readily
conveys its intended message. Key words and
phrases should be emphasized with larger letters,
bolder typestyles and additional colors. Ideas should
be grouped logically and separated by layout and
spacing. Graphic elements, especially digital color
graphics, can greatly enhance the speed and
thoroughness of communications.
Readability
5. The sign should incorporate some design elements
that will help it stand out conspicuously in the
landscape. Color contrast, changeable components,
motion, uniqueness of design and/or subconscious
attraction can serve to make a sign more noticeable.
Noticeability
6. Typestyle selection is critical to the effectiveness of a
sign. The proper font should convey the desired
image without sacrificing the ability to distinguish
individual letters. Many script and specialty typestyles
are difficult to read, especially over greater viewing
distances.
Legibility
7. You may have a great looking sign, but what if your
potential customers cant make out what its
supposed to mean? Ensuring that potential customers
can view and understand your message is vital to your
businesses success.
Proper Sign Distance for Optimal
Visibility
8. The distance between your sign and its viewers is the number one
factor in determining the type of LED display you will need.
Longer distances require less resolution and shorter distances
require higher resolutions.
In addition, if you are traveling at 90 KPH on a freeway, and the sign
is 180 meter away at a truck stop, the text letters must be at least
50 centimeter tall to be legible. Likewise, if you are standing 18
meter away from a street level sign, the letters need only be 5
centimeter tall to be legible.
The rule of thumb is that you need 1 centimeter for every 1.2 meter
of viewing distance.
