Paste any text to get reading time, speaking time, and a Flesch-Kincaid readability score — in one place, instantly.
Open full calculator →The "4 min read" estimates you see on blogs and newsletters are typically based on a single average reading speed — usually 200–250 words per minute. That's fine as a rough heuristic, but it ignores how much reading speed varies by content type and reader. Dense technical documentation is read at 150–200 WPM; light fiction or blog content can be skimmed at 300+ WPM. WordWise shows all three speeds simultaneously — slow, average, and fast — so you can pick the estimate that fits your audience rather than defaulting to a number that may not apply.
Flesch-Kincaid readability scores measure the complexity of text based on average word length and average sentence length. Higher scores (70–100) mean easier reading; lower scores (30–50) indicate complex, formal text. For most web content targeting a general adult audience, a score of 60–70 is the right target — readable but not dumbed down. Academic writing often sits below 40, which is appropriate for that audience but would drive most blog readers away.
Speaking time uses different baseline speeds than reading time. A typical presentation or keynote runs at 110–130 WPM — speakers slow down for emphasis, pauses, and audience comprehension. Conversational speech runs around 130 WPM. Paste a speech draft to see exactly how long it will run at each pace before you stand up in front of a room.

The most commonly cited figure is 238 WPM for silent reading of non-fiction, from a 2019 meta-analysis of 190 studies. In practice it varies: technical content is read at 150–200 WPM, light fiction at 250–350 WPM, and skimming at 600+ WPM with lower comprehension.
At 238 WPM (average), about 4 minutes 12 seconds. At 150 WPM (slow), just under 7 minutes. At 320 WPM (fast), about 3 minutes 8 seconds. WordWise calculates all three simultaneously for any text you paste.
For most web content, a Flesch Reading Ease of 60–70 is the target — equivalent to an 8th-grade reading level, appropriate for a general adult audience. Marketing copy aims for 70–80. Academic writing typically falls below 50. Lower scores aren't automatically bad if your audience expects technical or formal language.
Word count divided by reading speed in WPM. A 1,500-word article at 238 WPM takes 6.3 minutes. WordWise counts words from pasted text and applies slow (150), average (238), and fast (320) WPM speeds simultaneously.
Speaking is slower than reading. Presentations average 110–130 WPM (speakers slow for emphasis and clarity). Conversational speech runs about 130 WPM. For a 1,000-word speech, plan for 7–8 minutes at a presentation pace.
For SEO, 1,500–2,500 words is the most commonly recommended range for competitive keywords. Short-form (300–800 words) can rank for low-competition queries. Long-form (3,000+) attracts backlinks and ranks well for complex topics. The ideal length is the minimum needed to comprehensively answer the reader's question.
