Thesis & Dissertation Abstract Word Count by University

Writing my thesis abstract was one of the most frustrating parts of the whole dissertation process. I had just spent years on this research, and now I needed to squeeze it all into 300 words? The word limit felt impossible — until I figured out what actually mattered.

Here's everything I learned about abstract word counts, including the strict limits different universities enforce and how to make every word count.

Abstract Length Overview

University Requirements

Common University Standards

Always Check Your Institution

Requirements vary significantly between universities. Before writing your abstract:

• Check your department's thesis guidelines
• Review your graduate school's formatting requirements
• Look at recent dissertations from your program
• Ask your advisor for clarification

Masters vs PhD Abstracts

Master's Thesis Abstract (150-300 Words)

A master's abstract is typically shorter because:

• Scope of research is narrower
• Less complex methodology
• Fewer findings to summarize
• ProQuest recommends 150 words maximum

PhD Dissertation Abstract (200-350 Words)

Doctoral abstracts are longer to accommodate:

• More comprehensive research scope
• Complex methodological approaches
• Multiple research questions
• Broader theoretical contribution

Abstract Structure

Key Components

A well-structured abstract includes (in order):

1. Background/Context: 1-2 sentences introducing the topic
2. Research Question/Objective: What you investigated
3. Methodology: How you conducted the research
4. Key Findings: Most important results
5. Conclusions/Implications: What the findings mean

Writing Tips

Before Writing

• Write the abstract last, after completing your dissertation
• Have your main chapters open for reference
• Identify 3-5 keywords for your research

During Writing

• Use past tense for completed research
• Write in third person (most disciplines)
• Avoid citations and references
• Don't include figures or tables
• Be specific about methods and findings

Revision Strategies

• Cut unnecessary words ("very," "basically," "essentially")
• Remove redundant phrases
• Combine sentences where possible
• Ensure every sentence adds value

Common Mistakes to Avoid

Content Mistakes

• Too vague: "This study examines important issues"
• Missing methods: Omitting how research was conducted
• No results: Failing to state key findings
• Background overload: Too much context, not enough research

Formatting Mistakes

• Exceeding word limit (immediate rejection in some cases)
• Using abbreviations without explanation
• Including citations
• Multiple paragraphs (unless required)

Language Mistakes

• Future tense for completed research
• Informal language or contractions
• Subjective statements without evidence
