What is the most common limitation placed on signs?

The most common limitation placed on signs is often related to the size of the sign. Size regulations are implemented to maintain aesthetics and safety in various environments, especially in urban settings where visual clutter can detract from the surrounding architecture and landscape. Controlling the size of signs helps ensure that they do not overwhelm other elements of the streetscape, contribute to distractions for drivers, or encroach upon pedestrian pathways.

Regulations typically specify maximum height and dimensions for signs, which allows for uniformity and reduces the potential for competition between signs for attention. While location, content, and zoning also play significant roles in sign regulation, size is a primary factor because it is directly linked to visibility and the overall harmony of the area. Size limitations can also work alongside other regulations to ensure that signage is effective without becoming a visual nuisance.
