adobe reader xi and coreldraw 9

I have a pdf file of an rc plane plan.  When i take a snapshot in Adobe Reader XI, of a component at 200%, (because I want the plans twice as large), copy, then paste in coreldraw 9, the component is too large for the custom sized page I created.  I took measurements in reader xi of the component, doubled them to get page size for coreldraw.  I made the coreldraw page sufficiently large enough to accommodate the double sized reader component.  It just will not fit.  Zoom level in coreldraw-100%.  Anyone have a clue what the problem is?  I admit I don't use corel often, probably just enough to make me dangerous!  Appreciate any help with this problem
