Calculateur de Reading Speed
Calculate reading speed in words per minute and estimated time to read a document.
Formula and method
This calculator computes Estimated reading time directly in your browser without sending data to an external server.
Mathematical formula
- Estimated reading time:
wordCount ÷ wpm
Variables and parameters
- Total word count (wordCount): default value 50000.
- Reading speed (wpm): default value 250 wpm.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
