Zooming in on a PDF Document
When viewing a PDF document in Acrobat Reader, you will notice a band of icons immediately above the document you are viewing. Two of those icons are a magnifying glass and a plus symbol.
You can magnify a specific spot on a PDF map by clicking on the magnifying glass icon, then moving down to the map, centering the magnifying glass on the spot, and clicking again. Continue clicking to zoom in more.
Alternatively, you can simply click on the plus sign to increase the magnification of the whole map. Or choose an ideal magnification by selecting a percentage in the drop-down menu next to the plus sign.
