Most people believe they read at about the same speed as everyone else. They're wrong — by a factor of three. The average reading speed for an adult is around 238 words per minute (WPM) for non-fiction, but trained speed readers can hit 700 WPM, while young children read as slowly as 80 WPM.
This matters beyond trivia. If you write blog posts, design online courses, craft email newsletters, or create any content that people read — knowing the real reading speed benchmarks helps you accurately predict how long people will spend with your content, and how to frame that time for them.

Average Reading Speed by Age Group
Reading speed isn't a fixed adult trait — it develops progressively through childhood and peaks in early adulthood. Here's what research shows at each stage:
- Grade 1 (age 6–7): 80 WPM. Children are decoding individual words, not yet reading for meaning.
- Grade 3 (age 8–9): 115 WPM. Decoding becomes automatic; comprehension starts lagging less.
- Grade 6 (age 11–12): 185 WPM. Speed approaches adult range; vocabulary gaps still cause slowdowns.
- High school (age 14–18): 200–250 WPM. Most adults plateau near this range after finishing formal education.
- College-educated adults: 238–260 WPM average. The benchmark most content tools use for reading time estimates.
- Avid/professional readers: 300–400 WPM with near-full comprehension. These are readers who consume books, journals, or dense reports daily.
The 238 WPM figure for adults comes from a widely-cited 2019 study by Brysbaert published in the Journal of Cognition, which analyzed data from 190 studies involving nearly 18,000 participants. It's the most reliable modern benchmark and the one our reading time calculator uses.
Average Reading Speed by Content Type
People don't read all content at the same pace. The difficulty, density, and purpose of a piece dramatically affects how quickly a reader processes it. Using a single WPM estimate across all content types leads to inaccurate reading time predictions.
- Fiction / light reading: 250–350 WPM. Familiar vocabulary, narrative flow, and entertainment motivation all accelerate reading speed.
- Blog posts / general non-fiction: 200–250 WPM. The standard web-reading benchmark. Readers scan headings and skim bullet points, which can raise effective reading speed.
- Technical documentation / academic text: 100–150 WPM. Dense jargon, complex sentence structure, and the need to re-read for understanding all slow readers significantly.
- Proofreading / editing: 50–100 WPM. Careful attention to every word reduces speed to a small fraction of normal reading pace.
- Skimming / scanning: 600–700 WPM. Many web readers skim first to decide if a page is worth a full read — which is why clear headings and opening paragraphs are critical.
The practical takeaway: always match your WPM estimate to the type of content your audience is reading. A technical API reference read at 238 WPM will wildly underestimate actual time spent.
6 Factors That Affect Average Reading Speed
Reading speed isn't purely a function of intelligence or practice. Several external and internal factors push it up or down:
- Vocabulary familiarity. Encountering an unknown word forces a pause. Content heavy with technical terms or jargon consistently reads 20–30% slower than plain-language equivalents.
- Sentence length and structure. Long, multi-clause sentences require more working memory. Shorter sentences (15 words or fewer) are processed faster and with better retention.
- Typography and layout. Line length, font size, contrast, and line spacing all affect reading speed on screen. The optimal line length for reading is 45–75 characters — wide-column layouts slow people down measurably.
- Reading medium. Studies consistently show people read print about 20–30% faster than on a screen, due to reduced eye strain and the absence of distractions. E-ink displays (like Kindle) fall between the two.
- Reader motivation and purpose. Someone reading for pleasure reads differently than someone reading to pass an exam or prepare for a client meeting. Purpose-driven reading is slower and more focused.
- Sub-vocalization. Most people silently "mouth" words as they read, which caps speed at speaking pace (~150 WPM). Reducing sub-vocalization is the core technique behind speed-reading programs.
Average Reading Speed vs Comprehension: The Trade-Off
Speed-reading is a popular idea with a significant caveat: at very high speeds, comprehension collapses. A 2016 meta-analysis in Psychological Science in the Public Interest concluded that techniques like RSVP (Rapid Serial Visual Presentation) and skipping regressions do accelerate reading — but at a measurable comprehension cost above ~400 WPM.
The sweet spot for most adults is 200–300 WPM, where speed and comprehension are both near their maximum for the individual. Beyond that, it's diminishing returns unless you're skimming specifically to locate information.
What this means for content creators: don't assume your readers are skimming at 600 WPM. Use 238 WPM for general blog posts. If you're writing a heavy technical guide, budget 150 WPM instead — and your predicted read time will be far more accurate.
How to Apply Average Reading Speed to Your Content Strategy
Once you know a reader's likely WPM, you can make smarter decisions at every stage of the content process.
Displaying Estimated Read Time on Your Blog
Medium pioneered this UX pattern and the data backs it up: articles with a visible read time label get higher engagement and lower abandonment rates. Readers who know a post takes 4 minutes are far more likely to commit to it than readers staring at an unknown wall of text.
The formula is simple: divide your word count by 238 (or your chosen WPM benchmark) to get minutes. Round up to the nearest minute. A 1,200-word post at 238 WPM = 5.04 minutes → display as "5 min read."
Optimising Email Newsletter Length
Email attention is scarce. Most marketing emails are read in under 60 seconds, which translates to roughly 200–250 words. For newsletters aimed at engaged, niche audiences (think developer digests or investment newsletters), readers willingly spend up to 5–7 minutes.
Benchmark your newsletter length against your open rate and click-through data. If click rates drop sharply on longer sends, your audience is telling you it's too long for their reading habits.
Converting Blog Posts to Video Scripts
Average speaking speed for a clear, professional presentation is 130–150 WPM — roughly 40% slower than reading speed. A 1,500-word blog post takes 6 minutes to read but becomes a 10–12 minute video script.
When repurposing written content for video or podcast, plan to cut your word count by roughly 40% to hit the same intended duration. This isn't about removing value — it's about removing the connective tissue that written prose needs but spoken audio doesn't.
How to Calculate Read Time Using Average Reading Speed
The calculation itself is straightforward. Use these steps to estimate read time for any piece of content:
- Count your words. Use your writing tool's word counter, or paste your text into an online counter.
- Choose your WPM benchmark. Use 238 WPM for general blog posts, 150 WPM for technical content, 130 WPM for spoken scripts.
- Divide words by WPM. The result is your estimated reading time in minutes.
- Or skip the maths entirely. Paste your full text into the free Reading Time Calculator and get an instant estimate, including word count and character count.
Example: a 2,000-word technical guide ÷ 150 WPM = 13.3 minutes. Displayed as "13 min read." The same 2,000 words at 238 WPM (blog benchmark) would display as "8 min read." The difference matters for your reader's commitment decision.
Frequently Asked Questions
Is 250 WPM a good reading speed for adults?
Yes — 250 WPM is solidly average for a college-educated adult reading non-fiction. The research benchmark is 238 WPM, so 250 WPM puts you slightly above average. If you're reading at 200 WPM with good comprehension, that's also completely normal. Speed matters less than comprehension.
What is a fast reading speed?
Consistently reading at 400+ WPM with full comprehension is considered fast. Speeds above 600 WPM typically involve some form of skimming rather than true word-by-word reading. Claimed speeds of 1,000+ WPM from speed-reading courses come with significant comprehension trade-offs that the marketing glosses over.
Does reading more improve your reading speed?
Moderately, yes. Regular reading builds vocabulary, increases pattern recognition for common sentence structures, and reduces the cognitive load of decoding — all of which raise your effective speed. But the gains are gradual. According to reading science research, most speed improvement from practice occurs in childhood; adult reading speed is relatively stable without deliberate training.
How many WPM is a 5-minute read?
At the standard 238 WPM benchmark, a 5-minute read works out to approximately 1,190 words. Round up and say anything between 1,100 and 1,300 words will display as a 5-minute read for most readers.
Wrapping Up
The average reading speed for adults is approximately 238 WPM for general non-fiction — but that number shifts significantly based on content type, reader age, medium, and purpose. Using a blanket figure without accounting for these variables leads to inaccurate read time estimates and missed expectations for your audience.
Use the benchmarks in this guide to choose the right WPM for your content type. Apply that to your word count and you have an honest, reader-respecting read time estimate — not a guess.
