Start with 240 words per minute
Average silent reading is a practical starting point. Use Slow for dense study material and Fast for familiar, lightweight writing.
Reading time, without the guesswork
Turn a word count or full document into a practical reading-time estimate. Paste text or choose a file; everything is analysed locally in your browser.
Reading time is the amount of text divided by a reading speed. The useful part is choosing the right unit and rate for the document.

Chinese and Japanese do not consistently separate words with spaces, so the calculator applies character-based rates.
Exact section durations are calculated first and then added to the total.
The calculator reads supported files on your device. It does not send text, filenames or chapter titles to DocsToAudio servers, analytics or third-party AI services.
Use pasted text for a quick answer, or analyse a longer document with chapter-level results.
Plain text and manually structured chapters.
Modern Word documents with heading structure.
Ebooks with spine and table-of-contents structure.
Text-based PDFs with bookmarks when available.
Scanned PDFs, encrypted files, DRM-protected EPUBs and legacy .doc files are not supported.
READING TIME IS ONLY THE BEGINNING
How the estimate works, what stays private, and where document structure has limits.
Divide the word count by your reading speed in words per minute. The calculator also applies character rates for Chinese and Japanese.
About 240 words per minute is a useful baseline for silent reading. Dense or unfamiliar writing usually takes longer.
Yes. The browser extracts available PDF text locally. Scanned pages without a text layer require OCR and are not supported.
No. Text and selected documents are processed in your browser and are not uploaded or saved.
No. This estimates silent reading; speaking and narration usually use a different pace.
