Layout Guidelines Here are some simple guidelines we recommend for all interior signage:
1) Select uniform copy locations and justifications whenever possible. The nine layouts shown below are samples of each combination of horizontal and vertical justification.
2) Text sizes should be large enough to be legible, and still be esthetically pleasing. A ½" high letter is readable from about 25 ft. by those with good vision.
3) Keep your interline spacing (the distance from the baselines of consecutive lines of text) uniform, usually about 150% the letter height.
4) Maintain margins roughly equal to the height of the capital letters you are using.
5) Selecting an appropriate sign size is also critical. Keep in mind that different words and phrases have different widths and numbers of required lines. If small signs are required, consider abbreviations and elimination of extra words as options.
6) We also very strongly recommend using one typestyle or styles from the same "family" throughout a facility (see the examples below). The more specific your information, the closer your design will match the product.
7) Remember, Diskey's designers will be happy to assist or advise in any way. The least significant detail now may later become much more prominent.
Illustrated above are about half of the the Helvetica / Arial typestyle family. As you can see by the diversity in just those shown here, lack of specification can result in something that not only wasn't in the original plan, but isn't even ADA compliant!
