What scale is the Wendy's Photometric Plan drawn to?

The correct scale of 1" = 20 means that every 1 inch on the photometric plan represents 20 inches in real life. This scale is commonly used in photometric plans to provide a clear and manageable representation of lighting layouts and distribution across a site.

Using a scale of 1" = 20 helps ensure that the details of light placement, intensity, and distribution can be accurately visualized and interpreted. It strikes a balance between providing enough detail without making the plan too crowded or difficult to read, allowing electrical contractors and planners to effectively communicate design intentions.

The other scales may result in plans that are either too large or too small to effectively convey the necessary information, making 1" = 20 a practical choice for this type of planning document.
