Not at “the average reader’s” pace — at yours. Measure it once with the built-in test, say how many minutes a night you actually read, and get a finish date instead of a shrug.
The pace presets bracket the research: large meta-analysis puts typical adult silent reading around 240 words per minute for ordinary prose, slower for dense material, faster for light fiction. Page density is the mushier number — a “page” runs anywhere from 200 to 350+ words depending on trim size and typesetting, which is why the presets are honest ranges and why measuring your pace matters more than any constant.
People are reliably wrong about their own speed — most guess high. The test times you on a ~220-word passage read normally, which lands within a few percent of your real sustained pace for similar material. It’s saved in your browser only (like the world clock’s city list) so the answer is personal next visit too. Reading tougher material? Knock 20–30% off.
Exactly as accurate as your honesty about “minutes per day.” The math is trivial — the tool’s real job is making the trade-offs visible: drag the slider and watch a month become a fortnight. Life, of course, remains undefeated.
The pasted text tab counts words and gives reading time at your pace plus speaking time at ~130 wpm — the usual planning figure for talks and presentations. Pasted text never leaves the page.
