I'm using ArcGIS Pro 2.2.3 and want to set my layout scale bar to have a fixed length (1 inch) regardless of the map extent. The Adjust Division Value resize behavior usually worked in ArcMap (it would round to the nearest 10 but otherwise would keep the length static), but in Pro it always resizes smaller than I want. For example, my current map has an extent of 1,680 which means a scale of 140 feet should be exactly 1 inch. When I manually set the length to 140 though and then set the behavior back to Adjust Division Value, it drops the length to 130 feet (see attachment):
It does this regardless of the chosen extent. Does anyone know a way to resolve this issue?
