Hello! I'm trying to manually resize the layout (not data frame) in the layout view in ArcMap. Is this possible? See image - I want to manually adjust the outermost left and right of the entire image but the only options I'm seeing are preset sizes. I need to get the same amount of space on all outermost parts of the shapefile, if that makes sense. Is this possible, or am I only allowed to pick from the map layouts that ArcMap has set up? For example, I want to change the width to 8.0 instead of 8.5 in my second example. Is this possible? Thanks!
