How can you tell. Print it out at what scale ? and what
precision.
Don't guess and measure with a ruler. Use a mouse and the CAD file
and
have the Cad program measure it. CAD might scale a Tabloid into
11/17 with
3/8 borders or anything. It is relative. When 1:1 you normally use
D and E size paper
and make sure the CAD is printing at only 1"=1" or 10" or 5 or some
even number.

Cad fits a drawing into the paper size and the scale of ink vs Tube
vs planned is always off.

The X and Y scales of a paper print may differ because separate
mechanisms control them.
