Statutory signage

In signage a pictogram is the image used to convey the message of the sign. In statutory signage pictograms follow a very specific set of colour, shape and sizing rules. In UK and EU signs the width of a sign's pictogram is set at 80% the height of the area it is printed to. In the US, a pictogram that identifies a room or space (such as the gender pictogram on a restroom signs), must follow specific rules. Other pictograms that must comply with rules are the four "Symbols of Accessibility" specified in the ADA Accessibility Guidelines. See the article *ADA Signs

For example : On an A4 Portrait UK / EU statutory sign (210 x 297mm) using 2/3s of its area to display the pictogram 210 w x 198 H (mm) and 1/3rd for its text display, the pictogram would be 158.4 mm wide. (80% of 198 mm).

In the US, the pictogram described above would have to be located within a six inch high clear field, with raised characters and braille located beneath the field.

For a pictogram to work it must be instantly recognizable and understood by all. For this to work the image must be kept consistent. In its purest form a pictogram on a sign should be understood even if there is no text present. Following the standard colour and shape rules increase the likely hood of a universally understood pictogram and therefore sign.

According to the book "Discovery-Based Retail," signage falls into three groups: decorative, adding eye-pleasing color; informational; or directional, providing guidance.

Use of shape

Signs have very specific shapes. These shapes on signs send messages to the audience and form a set of rules that should be followed when developing signage. The particular shapes may vary among different parts of the world.
