View real time PDF coordinates

One way to determine the exact x,y coordinates of elements on a PDF page is to open the PDF in GIMP (the image editing tool).

• File / Open
• Open pages as images (In dialog)
• Import

As you hover over different parts of the PDF(image) with the mouse, the bottom left corner displays the x,y coordinates. You can adjust the unit of measure, pixels, points, inches, etc...

By default, the point (0,0) is located at the top, left. If you want to have the x,y coordinates start at the bottom left, you can flip the image vertically. Everything will be upside down, but it is all a matter of perspective.
