How Does It Work?

Free reading time and speaking duration calculator. Estimate how long it takes to read or deliver an article, essay, or speech across slow, average, and fast WPM speeds with page count benchmarks.

Mathematical Formula
Reading Time = Total Words / Reading WPM | Speech Time = Total Words / Speaking WPM

Standard silent adult reading averages 200–250 WPM, while public keynote presentations average 130–150 WPM.
