Where do the reading speed numbers come from?

Speeds are drawn from peer-reviewed linguistics research, primarily the 2019 Brysbaert study ("How many words do we read per minute?") and CJK reading-speed studies. They represent average silent reading rates for adult native speakers.

Why do CJK languages use characters per minute instead of words?

Chinese, Japanese, and Korean text does not use space-delimited words in the same way as Latin-script languages. Characters (or mora for Japanese) are the standard counting unit in reading-speed research for those scripts.

Can I adjust the reading speed?

Yes. The speed slider lets you fine-tune within a range around the research average, so you can account for slow readers, technical text, or fast skimmers.

What if my language is not in the list?

Pick the closest language by script family, or use "Other / Unknown" which falls back to a general cross-language average of 200 WPM.

Does the tool send my text to a server?

No. All processing happens in your browser. No text is transmitted anywhere.

Summary

Different languages have different average silent reading speeds. An English reader averages around 238 words per minute, while Japanese readers average about 357–400 characters per minute in kana/kanji text. This tool applies peer-reviewed per-language speed benchmarks so your reading time estimate reflects the actual script and language, not just a single universal WPM value.

How it works

Paste or type your text into the input field.
Select the language of the text from the dropdown.
The tool counts words or characters depending on the language script.
It divides the count by the research-backed average reading speed for that language.
Reading time is displayed in minutes and seconds, with raw count stats below.
