Frequently Asked Questions
How is reading time calculated?
Reading time = Total Words ÷ Reading Speed. The average adult reads approximately 238 words per minute according to a 2019 meta-analysis of 190 studies by Brysbaert at the University of Ghent. This tool shows estimates for slow (150 wpm), average (238 wpm), and fast (350 wpm) readers.
Does showing reading time improve engagement?
Yes. Medium and Substack show reading time prominently because it reduces friction — users know the commitment before they start. Research shows articles with displayed reading times have higher completion rates and lower bounce rates.
Should I use reading time on my blog?
Yes, if your posts are more than 3 minutes. Add it near the title or author block. Keep it honest — inflating it to seem more substantial or deflating it to reduce friction both work against you.
Is my data stored?
No.
Can I use this on mobile?
Yes.
