I'm using data driven pages (DDP) in ArcMap 10.3. The index layer is a polygon feature class and I would like to know the scale that each data driven page exports at. Ideally there would be a way to append an attribute to this layer that indicates the scale for each page (200+ pages). (I know DDP can be set on previously existing scale attribute value, but when its based on the various sizes of each polygon, I want to know what the numeric value is.
While that is my primary question, the ultimate goal is to be able to apply a different size label to corresponding features in each map. If I know the scale of each page, I can then adjust label size accordingly by page.
