Enter your word count (or paste in text) and set your reading speed to find out exactly how long it will take to read. The Reading Time Calculator returns your silent reading time, read-aloud time, plus a word and character count — broken down for slow, average, and fast readers.

The average adult reads silently at around 238 words per minute (WPM). Reading aloud is typically slower, averaging about 183 WPM. Speed readers can reach 400 WPM or more, though comprehension can vary at higher speeds.
Reading time is calculated by dividing the total word count by your reading speed in words per minute (WPM). For example, a 1,000-word article read at 238 WPM takes approximately 4.2 minutes. This calculator does that math instantly for both silent and read-aloud scenarios.
Subvocalization is the inner voice you 'hear' while reading silently. Most people subvocalize automatically, which tends to cap silent reading speed near spoken speeds (around 200–250 WPM). Speed reading techniques try to reduce subvocalization, but eliminating it entirely can lower comprehension.
Research suggests that significantly increasing reading speed — especially above 400–500 WPM — often comes at the cost of comprehension and retention. Moderate speed improvements through practice (200–350 WPM) can maintain good comprehension for most readers.
The average novel contains roughly 80,000–100,000 words. At an average reading speed of 238 WPM, that works out to approximately 5.6–7 hours of reading time. Non-fiction books tend to be shorter, around 50,000–70,000 words, taking 3.5–5 hours.
RSVP is a technique that flashes words one at a time at high speed directly in your line of sight, eliminating the eye movement needed in normal reading. It can help some users read faster, but studies show that comprehension and the ability to re-read for context are often reduced compared to traditional reading.
For speeches and presentations, use the 'Read Aloud Speed' setting, which defaults to 183 WPM — the typical conversational speaking pace. Professional presenters often speak at 150–180 WPM for clarity. Simply enter your word count and adjust the read-aloud speed to match your delivery style.
Reading at 400 WPM instead of the average 238 WPM cuts reading time by about 40%. For a 10,000-word article, that's roughly 17 minutes at average speed versus about 25 minutes — saving around 8 minutes. The savings compound significantly across longer books or heavy reading workloads.
