Choose a sensible reading speed
A frequently used rough estimate for general web reading is around 200–250 words per minute. Treat that as a starting point, not a universal average. Readers may move faster through familiar short updates and slower through dense explanations, unfamiliar terminology or second-language material. If your audience is studying a subject, a lower rate may be more honest.
Calculate the estimate
Count the words in the article body, divide by the selected words-per-minute rate, then round up to a whole minute for a simple label. For example, a 1,000-word article at 220 words per minute takes about 4.55 minutes, commonly displayed as 5 min read. Rounding avoids a false impression that the estimate is exact to the second.
Account for more than words
A word-count calculation does not measure time spent examining diagrams, code blocks, tables, charts, embedded media or interactive exercises. For a hands-on tutorial, consider whether readers need to complete steps as they read. You can add a separate setup or practice-time note when that is useful, rather than inflating the reading-time calculation.
Worked example: estimate a short article
An article with 1,200 words at a chosen speed of 240 words per minute gives an estimate of 5 minutes: 1,200 ÷ 240 = 5. If the article contains code samples, tables or step-by-step tasks, readers may need longer than the arithmetic suggests. Consider whether those elements are central to understanding the article before deciding whether to include them in the count.
Use one method across similar posts so readers can compare estimates. Recalculate after substantial edits, round up consistently when a partial minute remains, and label the result as an estimate rather than a promise about how long every visitor will take.
