PhD vs MPhil Thesis: Key Differences, Difficulty Comparison & Expert Insights

Postgraduate research degrees like the PhD and MPhil enable students to contribute new knowledge through independent study and a thesis. While both are research-based, they differ in objectives, depth, and academic expectations. Understanding these differences helps students make informed choices. This guide clarifies thesis distinctions, required commitment, and which path best suits academic or career goals.

What Is an MPhil Thesis?

The Master of Philosophy (MPhil) is a research-based master’s degree that combines elements of advanced academic coursework with independent research. Unlike taught master’s programs (such as MA or MSc), the MPhil is primarily focused on developing research skills, critical thinking, and methodological expertise.

For many students, the MPhil serves one of two main purposes:

It is a standalone research degree for those who want to enhance their academic credentials or specialize in a niche area of study.
As a pathway to a PhD, successful completion can sometimes allow students to upgrade to doctoral-level research.

Typical Length, Scope, and Duration

An MPhil thesis is usually shorter and less detailed than a PhD thesis. MPhil. The normal MPhil thesis is between 30,000 and 50000 words, but this varies by country and university.

The fact that it is intermediate is also indicated by its duration:

Full-time students (those enrolling on a full-time basis) take 1-2 years on average.
The part-time students, that is, the students who work part-time, may take 2-4 years as per the rules imposed by the institution.

Level of Originality and Research Contribution

While originality is required, the MPhil does not demand the same level of innovation as a PhD. Students are expected to:

Show good research methodology and methods of analysis.
Give a critical assessment of the available literature.
Contribute their own humble but original work to their field, oftentimes by addressing a small research gap or by using existing theories in a new setting or replicating studies with a stronger methodology.

Comparatively, a PhD dissertation needs to generate completely fresh information or test the current existing theories at large.

Example Disciplines Offering MPhil Programs

The MPhil is offered across a wide range of academic fields, particularly in:

Humanities and Social Sciences – History, Literature, Sociology, Political Science.
Sciences – Biology, Chemistry, Environmental Studies.
Interdisciplinary fields – Education, Development Studies, and Public Policy.

What Is a PhD Thesis?

The Doctor of Philosophy (PhD) is the highest academic research degree awarded by universities worldwide. Unlike coursework-based postgraduate degrees, a PhD is almost entirely focused on original research to advance knowledge in a particular field. For many students navigating this demanding journey, thesis help online has become a valuable resource to support their research efforts and writing process.

Earning a PhD demonstrates that the candidate has mastered research methodologies, critically evaluated existing literature, and made a significant, original contribution to their discipline. It is considered the gateway to a career in academia, advanced research, or specialist professional roles.

Thesis Expectations, Length, and Research Depth

The PhD thesis should be both comprehensive, methodologically rigorous and theoretically interesting. In contrast to the MPhil, where researchers only have to focus on modest contributions, the PhD involves:

Design and experiment on new models, theories or hypotheses.
Question and improve on previous knowledge in a significant manner.
Participate in providing evidence and discoveries that can either affect future research or practice.

The length of a PhD thesis varies by subject and institution, but typically ranges between 70,000 and 100,000 words. For instance:

Humanities and Social Sciences tend to be longer (80,000–100,000 words) due to extensive literature reviews and theoretical discussions.
Sciences and Engineering theses are often shorter (60,000–80,000 words), focusing more on experimental results and technical analysis.

Research depth is much more extensive than at the MPhil level, with a number of years of data gathering, multiple methodological directions, and interdisciplinary views.

Requirement of Novel Contribution to Knowledge

Originality is the key element in the PhD thesis. What the candidate is supposed to show is his/her research.

Develops new knowledge or theories.
Fills the huge gap in the literature.
Issues and suggestions that can be widely accepted, or propose an innovative utilization of a previously established technique.

The requirement is what has made the PhD different among all other postgraduate studies research degrees and made it the most prestigious academic award in the world.

Duration and Global Variations

An average PhD can be time-consuming depending precisely on the country, the sphere of study, and the type of a person, who is doing it – full-time or part-time.

United Kingdom and the Commonwealth Nations: 3 years (or 4 years full time) or 6 (or 7 part time) years.
United States: 457 years on average, because before the thesis, there is coursework and a comprehensive examination.
Europe (Bologna Process countries): A protracted period of between about 3 years and 5 years full-time.
Asia & other Regions: Different people may vary on the duration of the timeline, but most of the programs in this category fall between 3-6 years.
Moving on to a doctoral program after demonstrating an extraordinary research success is also allowed in other countries (UK, Australia)

MPhil vs PhD thesis difference

Although both are research-oriented postgraduate degrees, the MPhil and PhD differ significantly in terms of research scope, originality, and academic expectations. Understanding MPhil vs PhD thesis difference is crucial for students deciding which path best aligns with their academic or professional goals.

Research Scope & Depth

MPhil: is devoted to a medium depth of research and is usually limited to a narrow, definite question or small field of study.
PhD: Includes specialized in an in-depth type of study which may involve several complex questions and sophisticated procedures.

Originality Requirements

MPhil:

Contributes a small amount that is novel by improving a study that has already been done, or using established theories in new areas, or reproducing the work with better methodology.
PhD: Would have a significant and new contribution to knowledge, would introduce new theories, models, or challenge established paradigms.

Thesis Length & Word Count

To an MPhil degree: 20,000 40,000 words (may also reach 50,000 words, depending upon the institution).
PhD: Normally between 60,000 to 100,000 words, although in the UK the average is about 80,000 words.

Duration of Study

MPhil: 1–2 years full-time (2–4 years part-time).
PhD: 3–6 years full-time (and up to 7–8 years part-time in some countries, particularly in the US).

Supervision & Funding Opportunities

MPhil: Often not funded by someone other than the candidate; relatively fewer scholarships or research grants present. Surveillance is less intensive given that the research is more of a smaller scale.
PhD: More scholarships or fully funded job opportunities can be funded, and several universities, research councils provide scholarships or fully paid positions. The nature of research, being long-term and complex, tends to involve the supervisor more actively in most cases

Which Thesis Is Harder: MPhil or PhD?

While both MPhil and PhD programs are demanding, the level of academic rigour, emotional investment, and long-term career implications make the PhD considerably more challenging. For students struggling with this level of research, seeking thesis help online can provide valuable guidance and support. Here’s a breakdown:

Academic Rigor

MPhil:

Requires a solid understanding of research methods and the ability to critically evaluate existing literature.
The research is narrow in scope, often designed to demonstrate research competence rather than to transform the field.
Suitable for students transitioning from taught master’s programs to research-based study.

PhD:

Incorporates sophisticated research strategies, conceptual inventiveness and direct interaction with current arguments.
The demand to generate new knowledge entirely takes intellectual creativity and analytical depth to a very high level.
Oral examinations are a harsh preparation to show the degree to which the work of the student was original and the validation of his/her results.

Perseverance & Resilience:

A PhD course is a lot more rigorous when it comes to perseverance because typically, a student can spend months, sometimes years, without any supervision in the various research protocols, on-field activities, and deadlines to beat.
Doctoral students face a great number of burnouts and impostor syndrome, and MPhil students feel less stress-related.

When Should You Choose an MPhil Over a PhD?

You should choose an MPhil over a PhD if you want to gain research experience, enhance academic credentials, or prepare for teaching and professional roles without committing to years of doctoral study. It’s ideal for exploring research interests before deciding on a PhD or pursuing specialized academic careers.

While a PhD is best for academic or high-level research careers, the MPhil offers practical research preparation and academic exposure, especially valuable for those aiming to learn how to publish in Scopus journals and build scholarly credibility.

Final Verdict:

To sum up, we must select one that suits our interests, time, and research ambitions when performing a PhD and MPhil comparison. MPhil is shorter, or to have some research experience, or to bring you into good practice to take a teaching/professional job. There is a long-term commitment required with a PhD, along with articles of original research, which is whether one chooses to work in academia or within any organisation. Consider the goal in career goal, time limitation, financial limitations, and plans in the selection. Then consider yourself: do you require research experience of that sort to be competing, or merely some experience? A visit to a college counsellor and attainment of a professional thesis company may provide you with an informed choice and your degree programs, simply to fall in line with your career, tailored towards career aspirations and opportunities that you may desire.

FAQs About PhD and MPhil Theses

What is the main difference between a PhD and an MPhil thesis?

The main difference lies in depth and originality. A PhD thesis requires original research that makes a significant contribution to the field, often over 3–5 years. An MPhil thesis is typically shorter and less intensive, focusing on understanding existing research and may involve limited original work.

Is an MPhil required before a PhD?

No, an MPhil is not required before pursuing a PhD in most countries. Many universities allow students to directly enroll in a PhD program after a relevant bachelor’s or master’s degree. However, some institutions may offer an MPhil as an interim qualification or stepping stone within a PhD track.

Can an MPhil thesis be upgraded to a PhD?

Yes, in some universities, an MPhil can be upgraded to a PhD if the research shows significant potential for further development. This usually involves a formal review or upgrade process, where the student must demonstrate the capability and scope for a PhD-level project.

Is it easier to complete an MPhil than a PhD?

Generally, yes—an MPhil is considered easier and shorter than a PhD. It requires less time, research depth, and originality. However, “easier” can vary depending on the topic, institution, and student’s academic preparedness.
