How to read faster without losing comprehension: what the research says

1. Measure your starting point

Before changing anything, find out how fast you read now and how much you understand. Take our reading speed test: it takes a few minutes and gives you your speed and your effective speed, which accounts for comprehension.

For reference, adults read silently at about 238 words per minute for non-fiction and 260 for fiction (Brysbaert, 2019). There is more data by age and language in average reading speed.

2. What speeds reading up most: reading more and knowing more words

The most thorough review on the subject (Rayner et al., 2016) reaches an unglamorous but solid conclusion: language skill is at the heart of reading speed. What holds you back is less your eyes than the time your brain takes to recognise each word and fit it into the sentence.

So the authors’ advice is to practise reading and become a more skilled language user, for example by growing your vocabulary. In practice:

• Read every day, even if only for 15 or 20 minutes.
• Vary genres and topics: every new topic brings new vocabulary.
• When a word slows you down, look it up. Next time it will not.

3. Match your speed to your goal

Rayner and colleagues describe a trade-off between speed and accuracy: the faster you go, the less you understand. That is not a personal flaw; it is how reading works. The key is deciding how much you need to understand:

• Looking for a fact or deciding whether a text is worth it: skim headings, first sentences and conclusions.
• Reading for pleasure: your natural pace. Enjoying it counts too.
• Studying or learning something hard: slow down, and go back when you need to.

Skimming is useful when you do not need everything; the problem is skimming everything and believing you are reading just as well.

4. For non-fiction, preview first

Before reading a chapter of a non-fiction book or a textbook, spend a minute on its structure: headings, subheadings, summaries, charts. Knowing where the text is going helps each paragraph fall into place and means less rereading. And if you read with a specific question in mind, you will know which parts deserve to be slow and which you can move through faster.

5. Do not fight your brain

Two classic speed reading tips run against the research:

• “Kill your inner voice.” That voice is part of how we understand text; trying to suppress it entirely does not make you a better reader (Rayner et al., 2016).
• “Never go back.” Regressions (looking back at an earlier word) are not a bad habit: they are repairs. In an experiment that prevented readers from going back, comprehension got worse (Schotter, Tran and Rayner, 2014).

6. Remove friction

Often you are not reading slowly: you are reading interrupted. Small changes add up:

• Silence notifications while you read.
• Adjust text size, line spacing and light until reading feels effortless.
• Pick a fixed time of day. Consistency beats speed: our book reading time calculator shows that adding minutes per day shortens a book far more than gaining 30 words per minute.

7. What about word-by-word (RSVP) reading apps?

RSVP reading shows words one at a time in the same spot, so your eyes do not have to travel along the line. Used well, it helps you keep a steady pace and stay focused, especially with easy text or fiction at moderate speeds.

It has one clear limit: you cannot glance back. Since regressions help comprehension, the sensible approach is an app that lets you pause and step back, and slowing down for dense text. We go into detail in Does speed reading work?.

What will not happen

According to Rayner et al. (2016), doubling or tripling your speed without losing comprehension is unlikely. Courses promising 1,000 words per minute with full understanding, or “reading a page at a glance”, are not backed by science. Real gains are more modest, come with practice and show up mostly in the topics you read most.

Five-step summary

1. Measure your speed and comprehension with the test.
2. Read every day and build your vocabulary.
3. Decide before you start how much you need to understand, and set your pace.
4. Do not ban yourself from going back or reading “in your head”.
5. Retake the test in a month, calmly, and compare.
