100–150 wpm — Slow/careful reading, technical content, studying
200–250 wpm — Average adult reading speed
300–400 wpm — Fast reading, familiar content
Average is 238 wpm — the most-cited research figure (Brysbaert, 2019, based on 190 studies and 18,573 participants)

Reading Time Calculator — Free Online Tool with Exam Pacing
A reading time calculator estimates how long a piece of text takes to read, based on word count and a chosen reading speed. This one updates live as you type, runs entirely in your browser, and checks pacing against real ACT and SAT reading benchmarks — never uploading your text to a server.
"How long will this take to read?" turns out to matter more than it sounds — content writers use it to set reader expectations before a blog post, students use it to plan study sessions, and podcast or video creators use it to time a script before recording. This reading time calculator online tool converts any pasted text into a live estimate at your chosen pace, with a dedicated speaking-time mode for scripts and presentations, and ACT/SAT exam timer presets for students pacing themselves against a real test clock. Pro Mode extends this into domain-specific reading profiles, a full book reading time calculator for page counts or uploaded documents, a personalized reading speed test, script cue syncing for voiceover work, and bulk CSV export.

2Common Reasons People Calculate Reading Time
Publishers add a "5 min read" tag to articles for the same reason a menu lists prep time — it lets a reader decide whether now is a good moment before they commit. Students use the same math in reverse for test prep, converting a known reading speed into how many pages they can realistically get through in a fixed study block or exam section.
3Reading Speed Benchmarks
| Pace | Speed | Typical Use |
|---|---|---|
| Slow / Careful | 100-150 wpm | Technical content, studying, unfamiliar material |
| Average adult (silent) | 238 wpm | General non-fiction reading — the most-cited research figure |
| Fast / Speed reading | 300-400+ wpm | Familiar content, skimming, trained readers |
| Reading aloud | ~183 wpm | Narration, audiobooks, reading a script out loud |
| Presentation pace | 130-150 wpm | Live speech with pauses and emphasis |
| ACT Reading section | ~300 wpm | Exam pacing under time pressure |
The 238 wpm figure used as this tool's default comes from Marc Brysbaert's 2019 meta-analysis in the Journal of Memory and Language, which pooled 190 separate studies and over 18,000 participants — and found that the commonly-cited "300 wpm average" was measurably too high. Reading aloud is meaningfully slower than silent reading in the same research (183 wpm), because articulation becomes the bottleneck rather than comprehension, which is why speaking time and reading time are calculated separately here rather than treated as the same number.

4Frequently Asked Questions
Grounded in the primary research, not secondhand estimates — the 238 wpm reading-speed default follows Marc Brysbaert's 2019 meta-analysis published in the Journal of Memory and Language, exam pacing figures reference The Princeton Review's official ACT timing breakdown, and additional background on speed-reading limits comes from Wikipedia's overview of speed reading.
