When conducting a research study, it’s not just about what you do include—it’s also about what you don’t. That’s where delimitations and limitations come into play. These two elements help set the boundaries for your research while also revealing potential weak points. 

But what exactly do these terms mean, and how are they different? In this blog, we’ll break it down in a clear, student-friendly way—with definitions, examples, and tips you can use in your next research project to make it original.

What Are Delimitations in a Research Study? 

Delimitations are the choices and boundaries you set as the researcher. These are intentional decisions you make to narrow the scope of your study. Think of them as fences you build around your research question to keep it focused and manageable. 

Common Examples of Delimitations in Research: 

  • The specific population you chose to study (e.g., college students instead of high schoolers). 
  • The geographic area (e.g., only surveying people in New York). 
  • The time frame (e.g., focusing on data from 2020–2022). 
  • The method of data collection (e.g., using surveys rather than interviews). 

These aren’t weaknesses—they’re clarifiers. Delimitations help your reader understand what your study is and what it isn’t. 

Why Delimitations in Research Matter 

Without delimitations, your research could spiral out of control. You might try to tackle too many variables, populations, or time periods at once. Clearly stating your delimitations helps: 

  • Narrow your focus 
  • Set expectations for readers 
  • Increase the accuracy of your analysis 
  • Make replication easier for future researchers 

Imagine trying to study “all students in the world across all subjects over the past 50 years.” That’s just not doable. But by saying, “This study focuses on U.S. high school seniors’ math performance from 2021 to 2023,” you’ve drawn useful boundaries. 

What Are Limitations in Research? 

Limitations, on the other hand, are the unavoidable constraints in your study. These aren’t choices you made—they’re the realities you had to work with. Maybe you didn’t have enough funding for a large sample, or your participants dropped out halfway through. 

Limitations don’t make your research bad. All studies have them. What’s important is being transparent about them so readers can interpret your findings properly. 

Limitations in Research: Examples to Understand Better 

To help you grasp the concept more clearly, here are some limitations in research examples: 

Small Sample Size 

“Due to limited resources, the study surveyed only 40 participants, which may affect the generalizability of the results.” 

Time Constraints 

“The research was conducted over a four-week period, which may not have been sufficient to capture long-term behavioral changes.” 

Self-Reported Data 

“Because the data relied on self-reporting, it may be influenced by participant bias or inaccurate memory.” 

Limited Access to Resources 

“Certain proprietary datasets were unavailable, restricting the analysis to publicly accessible information.” 

By calling these out, you’re helping others interpret your results responsibly—and possibly even laying groundwork for future studies that can overcome those challenges. 

The Key Difference Between Delimitations and Limitations 

Let’s break it down simply: 

Term  Who Controls It?  What Is It?  Example 
Delimitations  You (the researcher)  Boundaries you choose to set  Only studying female participants 
Limitations  External or uncontrollable  Constraints you can’t avoid  Budget limits sample size 

Still Confused? 

Here’s a metaphor: If your research is a road trip, delimitations are the roads you choose to take. Limitations are the traffic and weather you can’t control. 

How to Write About Limitations and Delimitations in Your Paper 

Including a section on limitations and delimitations in your thesis, dissertation, or research article is essential. Here’s how to do it well: 

Be Honest

Don’t try to hide your study’s shortcomings. Being upfront shows integrity and allows others to evaluate your research with the right context. 

Be Specific

Instead of writing vague statements like “This study has limitations,” say, “A limitation of this study is the use of convenience sampling, which may limit the diversity of perspectives.” 

Explain the Impact

Don’t just state the limitation—explain how it might influence the results. For example: “Because only college students were surveyed, results may not apply to high school populations.” 

Connect to Future Research

If a limitation left a gap, suggest that future researchers address it. It shows critical thinking and helps build a research roadmap. 

Addressing Limitations Without Undermining Your Study 

It’s easy to worry that mentioning your limitations makes your study look weak—but the opposite is true. Discussing them: 

  • Makes your research more trustworthy 
  • Prepares readers for how to interpret your results 
  • Encourages future research to build upon your findings 

The goal is not perfection—it’s transparency. In fact, peer reviewers and professors often expect you to acknowledge what didn’t go perfectly. 

When Should You Use Limitations and Delimitations? 

You’ll most often include them in the Methodology or Discussion section of your research paper. Some instructors prefer a separate subheading like “Study Limitations and Delimitations.” 

Here’s what a sample paragraph might look like: 

“This study is delimited to first-year college students enrolled in psychology courses at a single university. While this allows for focused analysis, it limits the generalizability of findings. Additionally, the use of self-reported measures introduces potential response bias. Future studies may consider a broader, multi-university sample and include observational methods to strengthen findings.” 

Short, clear, and informative—that’s the sweet spot. 

How to Tell if Something Is a Limitation or a Delimitation 

If you’re unsure whether something is a limitation or a delimitation, ask yourself: 

  • Did I choose this? → It’s probably a delimitation. 
  • Was this beyond my control? → It’s likely a limitation. 

For instance: 

  • Choosing only participants from one school = delimitation 
  • Not getting enough participants due to low response rates = limitation 

Limitations and Delimitations: Why They’re Both Important 

Together, limitations and delimitations provide the full picture of your study’s framework and constraints. Think of them as two sides of the same coin—one you control, one you don’t. 

By clearly stating both: 

  • You set expectations for what the research can and can’t conclude 
  • You provide transparency to readers and reviewers 
  • You strengthen the integrity of your work 

No research is perfect—but clear boundaries and honest reflection make your study more meaningful, not less. 

Final Thoughts: Own Your Boundaries 

So, what are delimitations in a research study? They’re the scope-defining choices you make. And what about limitations in research? They’re the challenges you can’t help but face. 

Together, they shape your study and show readers that you’ve thought critically about what your research covers—and what it doesn’t. And that’s a mark of a responsible, thoughtful researcher. 

Next time you’re writing a research paper, don’t skip the delimitations and limitations section. Own it. Use it. And most importantly—make it work for your research.
