Reading Time Calculator
Estimate how long a text will take to read — adjustable for silent reading, reading aloud, or speed reading.
What is Reading Time Calculator?
The reading time calculator estimates how long a passage, article, book chapter, or speech will take based on standard reading speeds from education research.
Benchmarks: ~183 WPM aloud (average narration pace), ~238 WPM silent for a typical U.S. adult, ~300 WPM for college-educated silent readers, 500+ WPM for trained speed readers.
Formula
Minutes = words ÷ WPM
WPM figures come from Brysbaert (2019) and the Journal of Memory and Language meta-analysis of reading speed:
- Aloud: 183 WPM (sp. non-fiction narration)
- Silent, general adult: 238 WPM
- Silent, post-secondary: 300 WPM (technical reading trends slower, ~200 WPM)
- Speed reading: 400–700 WPM with measurable comprehension loss
Worked example
A 1,500-word blog post at average silent reading speed:
- 1,500 ÷ 238 = 6.30 minutes
- = 6 min 18 sec
The same article read aloud: ~8 min 12 sec.
How to use this calculator
- Paste or estimate your word count. In Google Docs or Word, the word count is usually in the status bar.
- Pick a reading style that matches how the text will be consumed.
- The calculator returns minutes + seconds and total seconds for scripting a video or podcast.
Frequently asked questions
How long is a typical audiobook per hour?
Professional narrators pace around 150–160 WPM — slower than conversation for clarity. A 50,000-word novella runs about 5–6 hours of finished audio. Audible estimates 9,300 words ≈ 1 hour.
What's realistic speed reading?
Most "speed reading" claims of 1,000+ WPM with full comprehension are exaggerated. Research (Rayner et al., 2016) caps comprehensive reading at ~600 WPM; beyond that you're skimming, which has its uses but is not reading in the usual sense.
Does reading on a screen slow me down?
Historically yes — about 20–30% slower on low-DPI screens. On modern high-DPI phones and tablets the difference is negligible. Paper still edges out screens slightly for retention and comprehension of long-form content.
How long should a speech be at a given WPM?
A 20-minute conference talk at a comfortable 150 WPM = 3,000 words. TED talks (~180 WPM) average 2,250 words for a 12-minute slot. Keynotes with stagecraft and pauses trend slower, around 120 WPM.
