About Reading Time
Estimate how long a PDF takes to read at study, average, or skim pace.
Upload a PDF and pick a pace: 150 wpm for study reading, 225 for average, 300 for skimming. Word totals come from the real text layer, and the estimate formats into hours and minutes.
Technical density slows everyone down — treat skims of dense papers as lower bounds. Scanned-image PDFs report near-zero until OCR’d. Files stay in your browser.
Where it is used
Planning reading sessions, scoping review work, labeling long reports, and setting expectations for courses.

Frequently Asked Questions
- Which pace should I choose?
- Study pace for learning, average for familiar material, skim for triage. Most people overestimate their speed — default to average.
- Do figures and tables count?
- Only their captions (when in the text layer). Budget extra minutes per dense figure or table.
- Why near-zero on my scan?
- No text layer exists in scanned images. OCR first, then estimate.
