Hyperlinked PDFs--Why The Difference in Display Sizes

cobalt-corsair Community Member Posts: 11
When I hyperlink PDFs and show them in a new Web2.0 window, some of the documents show in the window at small, almost-unreadable sizes (about 25%), while other show at what looks to be almost 75%.

Does anyone have an idea about why the different display sizes? I've looked at how large the PDFs were when I saved and closed them in the Extern folder, as well as any other ways I've displayed them recently, but that doesn't seem to have any bearing on the display size in Lectora.
