OLE is a method, not a thing. (Damn those acronyms!) So the discussion
hinges on what the object actually is -- some are resizable automatically or
otherwise, some are not.

However, the short answer is that Word, when it pastes an object, sizes it
to fit its container, if that is smaller than the object's original size.
The container being whatever you're pasting it into -- usually the text
boundaries of the page, or a table cell.

Looking at the Shapes collection is a good start: if this is empty your
objects are inline, so check the InlineShapes collection. In both cases, the
collection may contain objects other than those inserted by OLE, so you need
to check the type before doing any manipulation.
