I am new to ArcGIS and am doing an online course. For a part in one of my assignments, I need to make a map and label counties with their respective names. I find that if I set an appropriate font size in my labels to make them legible in data view, they are much smaller when I look at my map in layout view. I can up the font size in layout view, however I want to have a consistent font size between data and layout view. Otherwise, the font becomes huge in data view.
Also, my layout view extent is based on the extent in the data view so I don't understand why there is a difference in sizes.
