Formula
Reading time formula
Reading time = word count / words per minuteThe default reading speed is 225 words per minute. Speaking time uses a slower 130 words per minute estimate.
How to use
Steps
- Paste text into the calculator.
- Adjust reading speed if you want a custom estimate.
- Review reading time, speaking time, skim time, and word count.
- Use the estimate for articles, scripts, emails, and content planning.

Calculator use
Best for
- Use this reading time calculator to estimate how long an article, script, email, landing page, or post will take to read or speak.
- Checking reading time formula with the formula and assumptions visible.
- Comparing the result with the sample calculation and benchmark table before using it elsewhere.
- Writing, editing, naming, or formatting content for a specific platform or constraint.
Before relying on it
Check first
- Using the reading time without confirming that text and reading speed describe the same real-world case.
- Ignoring that the default reading speed is 225 words per minute. Speaking time uses a slower 130 words per minute estimate.
- Relying on the number without checking whether the visible assumptions match the real-world task.
- Counting drafts with hidden boilerplate, copied notes, or placeholder text still included.
Benchmarks
How to read the result
The calculator is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.
Under 1 minuteQuick read
Useful for short posts, emails, intros, and product copy.
2 - 5 minutesStandard article
A common planning range for short articles and explainers.
8+ minutesLong read
Often needs headings, summary, and stronger structure.

FAQ
Common questions
What reading speed does this use?
The default is 225 words per minute, but you can enter a custom reading speed.
Why is speaking time different?
Speaking is usually slower than silent reading, so the calculator uses 130 words per minute for speaking time.
Can this estimate video script length?
Yes. Use the speaking time estimate for scripts, voiceovers, and presentations.
Do text tools replace editing?
No. They check length, structure, formatting, and counts. Tone, clarity, factual accuracy, and brand fit still need a human review pass.
Can platform limits change?
Yes. Treat platform length limits as planning checks and verify important posts directly in the publishing interface before posting.
Why might another calculator show a different result?
Different calculators may use different rounding, assumptions, default rates, formulas, or input timing. Compare the visible formula and inputs before relying on the number.
