What is the minimum height for displaying street numbers on structures?

The minimum height for displaying street numbers on structures is typically established to ensure visibility from a reasonable distance. A height of 4 inches is standard in many jurisdictions, as it allows for the numbers to be easily read by emergency responders and visitors alike, especially from the street or sidewalk.

Using a height of 4 inches strikes a balance between readability and aesthetic integration into the building's facade. This dimension helps to alert emergency services quickly, which can be crucial in response situations. This standard can also be found in municipal codes or building regulations that dictate the requirements for address signage.
