Why is the default speed 230 words per minute?

230 WPM is the silent-reading average reported for Portuguese, measured across Brazilian subjects in reading-rate studies. It sits close to the cross-language adult silent-reading band of roughly 220 to 240 WPM, making it a sensible default for blog and article reading-time labels.

How is reading time calculated?

The tool counts the words in your text, then divides by your chosen words-per-minute rate and multiplies by sixty to get seconds. For example, 460 words at 230 WPM is two minutes. It then formats the result into whole minutes and seconds.

What counts as a word?

Any whitespace-separated token that contains at least one letter or digit is counted as a word. Standalone punctuation such as a dash or an ellipsis is ignored so it does not inflate the count.

Which speed should I use for a podcast or narration?

Use the read-aloud preset of about 140 WPM. People read silently faster than they speak, so spoken or recorded content takes noticeably longer than silent reading of the same text.

Does the estimate account for difficult vocabulary?

No. Reading time is a function of word count and speed only. Dense or technical Portuguese slows readers down, so pair this with a readability score, such as the Portuguese Flesch tool, when the material is demanding.

This tool estimates how long it takes to read a Portuguese passage by counting its words and dividing by a reading speed in words per minute. It is the same calculation used for the small read-time labels on blogs and news sites, tuned to a Portuguese silent-reading rate.

How it works

The formula is simply:

minutes = word_count / words_per_minute

The tool counts every whitespace-separated token that contains a letter or digit, divides by your chosen rate, and converts the result into minutes and seconds. The default of 230 WPM reflects the silent-reading average measured for Portuguese; presets cover slow and careful reading, fast reading, and reading aloud.

Tips and notes

Reading speed varies widely by reader, content density, and screen versus print, so treat the figure as a useful estimate rather than an exact time. For demanding or technical material, lower the WPM or check the text with a readability score first. When labelling audio or narration, switch to the read-aloud preset, since speaking is much slower than silent reading.
