"We do not err as a society when we innovate, but we do when we ignore what we disrupt or diminish while innovating."
Neuroscientist Maryanne Wolf, Director of the Center for Dyslexia, Diverse Learners, and Social Justice, often uses this quote from MIT scholar Sherry Turkle when presenting on her "print vs screens" research about disruption and change.
This quote perfectly encapsulates our opinion of the way the transition from paper to screens has occurred over the last 20+ years.
Innovations occur, new digital technologies are repeatedly invented to replace traditional books with on-screen reading.
The shiny new thing has a feature that replaces the old thing in some way. But what if the new thing comes with disruptive consequences from shifting to on-screen reading that are ignored? Often the decision to change from print to screens assumes there is no difference in learning outcome, but what if there is? Luckily, there has been a great deal of growing research conducted on this topic.
Educators and instructional designers should pay particular attention to recent research involving the comprehension differences between reading from print versus reading from screens. Studies conducted over very long periods involving over 180,000 participants combined indicate there are comprehension differences in some specific situations, and an overall preference for print among college students. New and ongoing research is looking into why this is.
We reviewed some recent studies that focus on comprehension differences and medium preferences (as in, paper vs screens), and made a list of the most surprising facts. We also reviewed recent studies that begin to unravel why the comprehension differences may exist and how young brains react differently to each reading medium.
This post would be remiss if we did not mention that there are benefits to technological innovations, and that some learners will prefer and benefit from using digitally delivered content on screens. Our point overall is educators and instructional designers in decision making positions should be aware that there is not a one size fits all decision to be made.
The simple fact is that research shows there are certainly measurable differences in comprehension when it comes to print vs screens, and as a result educators and instructional designers should consider the educational impact the reading medium will have on their students.
printMe1.com's approach is to use technology to provide a convenient print option for content creators and instructors using open source content to offer to their learners, after a PDF has been distributed digitally.
Here are the surprising facts from recent research about reading from print:
Fact 1- Students want print, print the PDF's they get, and think they do better when using print.

In a study published in 2018 involving 10,293 college students worldwide, a broad majority indicated a preference for print. There were 12 reading formats presented, and 78.8% of respondents chose print as the preferred reading format. This was strongest for younger college students and the strength of preference was less intense as academic rank increased.
When asked to respond to the statement "I prefer to print out my course readings rather than read them electronically", 68.8% agreed or strongly agreed.
Further review identified print was preferred when the content was lengthy (more than 5 pages).
Also of importance, the study indicated that the students themselves thought they would do better if they studied using print.

Salaz, Serap Kurbanoglu, Joumana Boustany, on behalf of the ARFIS Research Group. PLOS ONE. [https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0197444]
Fact 2- The "Digital Native" hypothesis that today's students have grown up in a digital world and won't perform as well using print simply isn't true.

A meta-analysis of reading comprehension studies was published in 2018 and examined research involving over 170,000 participants from 2000-2017. Each study tested participants by having them read the same text from a screen and in print, and then take a test on the content they read.
Not only did those reading from print perform better in testing than their peers reading from a screen, but surprisingly, the advantage of print did not shrink over the nearly 20 years covered by the study. It actually grew over that period, even as the readers identified as "Digital Natives" entered the research. Theories as to why this is happening involve readers developing habits early on that favor skimming instead of deep reading.
This contradicts the notion that today's students are "digital natives" and, therefore should do better from digital than print. Print is beneficial for course materials even today, and a strong inference can be made from this study that the presumed digital natives need print.
Study: Don't throw away your printed books: A meta-analysis on the effects of reading media on reading comprehension. (2018) Pablo Delgado, Cristina Vargas, Rakefet Ackerman, Ladislao Salmerón. Educational Research Review, 25, 23-38. [https://www.sciencedirect.com/science/article/pii/S1747938X18300101]
Fact 3- Reading from print on paper vs a device with a screen like a Kindle are different experiences and impact what information is remembered.

An experiment was conducted where participants had to read a long mystery story on a Kindle and also on a pocket sized print book. The research conducted by Anne Mangen, et. al. was published in 2019.
Previous studies have indicated that long informative texts, or long texts with some narrative elements, are comprehended better when reading from print versus a screen, and this experiment focused on comprehension of a literary work read on a Kindle and in print.
The participants were then tested on various levels of comprehension such as engagement, recall, and ability to reconstruct the plot of the story. The results between the formats were similar overall, but there was an inferior performance from screen readers with respect to temporal and chronological details.
There are theories evolving as to why this may be, and also referenced in research Mangen, et. al., conducted in 2013. Reading from print is a multi sensory experience. Holding an object in your hand like a soft cover bound print, or a hard cover book, and turning pages while reading may be adding important reference points from which the brain can remember the words it processes. "Where was it on the page?" & "How far was it in the book?" are two kinds of physical, 3D reference points that screens are not able to provide when reading, which might be impacting remembering when things occurred in the story. The progress in a print book can be measured in the height of a stack, the weight of the pages in one hand versus the other, changing over time. Scrolling, swiping, or pushing a button to electronically turn a page on a device is a 2D action with less sensory involvement.
A more obvious reason is it's easier to focus when reading from print because there are no electronic distractions and because we recognize the text is fixed and the brain can focus more on the content. The "fixity" of the text on paper possibly requires less cognitive load when reading.
An additional study by Pablo Delgado and Ladislao Salmerón, published online in late 2020 (and in print in 2021), confirmed that reading on screen caused a lack of focus, and that deficiency increased albeit by a small amount when under pressure from a time constraint. In this study, expository texts were studied as opposed to narrative texts because the expository texts contain many cognitively complex details like multiple conceptual ideas, unfamiliar vocabulary and lengthy sentence structures. This study focused on typically deep reading content instead of shallow reading.
This study's conclusion called on those educational decision makers to consider the fact that printed texts are more appropriate when it comes to in-depth reading, especially with lengthy texts, and be cautious when considering a complete shift from print to digital reading products.
Studies are showing differences in testing outcomes between the formats favoring print and the next steps are to further understand why.

Fact 4-Reading from print & paper uses higher frequency brainwaves that involve more focused attention and mental capacity than screens

A 2023 study measured the brainwaves used when reading from print vs screens using an electroencephalogram (EEG). The study involved 15 participants ages 6-8 and had them read two age appropriate 100-word expository texts from a print and also a screen while wearing EEG caps. The participants were asked comprehension questions after each version was read.
The EEG measured the brainwaves used while reading. Higher frequency waves (beta & gamma) associated with focused attention and higher mental activity were recorded while reading from print. Lower frequency waves (theta & alpha) associated with low attention spans and mind wandering were recorded while reading from a screen. The ratio of low frequency waves to high frequency waves was largest when reading from a screen and negatively correlates to visual attention abilities.
The study suggests when reading from screens the participants displayed brain activity patterns associated with daydreaming and less focused attention, whereas when reading from print the participants displayed brain activity patterns associated with concentration. Additionally screens were found to overload the attention of children in the study. The "cognitive load theory" suggests there is a maximum limit to the processing of sensory information, and exposure to screens attracts attention while trading off information processing quality.
The conclusion of the study was that differences in the EEG results and behavioral findings suggest differences that favor reading from print (paper) over reading from screens in children.

2026 Update- What newer research finds
Since this post was last updated, several new studies have been published that build on the facts above.
Scrolling may be the biggest culprit. A 2026 network meta-analysis pooled 56 studies and ranked reading formats for comprehension of informational text. Paper ranked first, followed by tablets, e-readers, computers, and smartphones. When readers had to scroll through text on a device, paper was clearly better than every digital device. When no scrolling was needed, the differences were small. This matters for anyone reading a long PDF on screen, because a PDF on a computer or phone almost always requires scrolling. A printed PDF removes the scrolling entirely.

Length matters. A 2024 meta-analysis found no comprehension difference for texts under 1,000 words, but longer texts were understood better on paper. This lines up with the ARFIS finding in Fact 1 that students prefer print once content runs past about 5 pages.

Even tablets fall short of paper. A 2024 meta-analysis focused only on handheld devices like tablets and e-readers, which feel more like a book than a computer screen does. It still found a small advantage for print.

Brain scans of middle schoolers point the same direction as Fact 4. Researchers at Teachers College, Columbia University recorded high-density EEG while 59 middle school students read passages in print and on screen. After reading in print, the brain responses showed deeper processing of the meaning of the text. After reading on screen, the responses looked like shallow reading.

Digital leisure reading doesn't pay off like print. A meta-analysis of studies involving nearly 500,000 participants found that leisure reading on digital devices was negatively related to comprehension for primary and middle school students, and only slightly positive for high school and college students. Print leisure reading has long shown a much stronger positive relationship.

Readers overestimate what they understood on screen. A 2019 meta-analysis of 33 studies found screen reading had a negative effect on performance compared to paper, mainly for informational text rather than stories. Readers also judged their own understanding more accurately on paper.
Study: Reading from paper compared to screens: A systematic review and meta-analysis. (2019) Virginia Clinton. Journal of Research in Reading, 42(2), 288-325. [https://doi.org/10.1111/1467-9817.12269]
Conclusion

Two large studies, one a meta-analysis involving over 170,000 participants and the other a survey of over 10,000 college students, measured comprehension differences & format preferences between reading from print vs screen and have produced some very surprising results.
Students prefer to print out their course materials, especially for longer texts. PDF's greater than 5 pages were determined in one study to be the point where print is preferable. Students also prefer print because they think they learn better from it.
Also surprising is that the advantage of reading from print did not fade as "Digital Natives" entered the research. The meta-analysis found the print advantage actually grew over the years studied. This may be from overemphasis on skills that promote skimming instead of deep reading.
A study that measured the brainwaves of participants with ages 6-8 while reading from print vs a screen found that the EEG results and behavioral findings suggest differences that favor reading from print (paper) over reading from screens in children. A 2024 study of middle schoolers found the same direction, with brain responses showing deeper processing after reading in print.
Researcher Anne Mangen, et. al., conducted an experiment to identify the differences between reading a literary work from print vs on a Kindle. Reading from print versus screens is beneficial for reading longer informational texts, or texts that are longer and may include narrative elements. For literary works, there is less of a difference between the formats except when testing for temporal or chronological details, in which case recalling those types of details is more successful when reading from print.
The newest research points to scrolling and text length as key factors. Long documents that have to be scrolled on a screen are where print shows its clearest advantage, which is exactly the situation of a long PDF read on a computer or phone.
