Do You Know? In PhD thesis, size does not matter! A PhD thesis can range from 150-200 pages. Only your new knowledge and new discoveries matter. A Big Bulky thesis of over thousand pages most probably, not relevant issues. I want your “Contributions and show me what Problem did you solve? Don’t show me 300 pages of just study background….”..200 pages of introduction, 150 pages of ……? that’s not the purpose of a PhD and it is not a PhD but a Thick book of Story…in my view.
