Font rendering inconsistent with in font size from specification

[Bijaya22345393m58u]

I am trying to understand why the application is rendering fonts bigger then whats defined in specification.

Spec:

3.6 -16.56 Td /F1 1 Tf
[(Testing font size output)]TJ

When I view the document with this spec in Adobe Reader, the text is clearly redable, the size looks bigger than whats on the spec but when I copy the text to Word document then I cant read anything as the text with actual size 1 is shown in document?

Does the application apply some sort of default text resizing?

If yes, how do i control this setting?
