Load your print in your favorite paint program. Cut and Crop it into individual images that are the same dimensions H x L x W. For example, the top view width should be the same as the front view's width.

Load each view into blender in a different 3D view port. Using View from the menu bar - Background image to bring up the window for setting the back ground image. See my example image..

Set the 'size' option in this window to the width of your cropped blue print image. This value has a maximum of 250 so in my example, I've just divided all of my dimensions by 10 so they will all be less than 250.

In the front view of my example, my actual photo is 379 x 276 so I've set the width to 37.9

You can test your set up by placing the 3D cursor on a point and checking it's position in each 3D window.

My Top view print was off a little bit, so you can see I adjusted it's size up by .5 so it lines up with the other view points. It was the same as the front and rear view's 37.9. Now it is 38.4 to compensate a little bit.
