About Reading time calculator
Reading Time Calculator estimates how long it takes to read any text at an average adult reading speed. Paste an article, blog post, or documentation page and get an immediate time estimate alongside word and character counts.
When to use Reading time calculator
- Add accurate reading time labels to blog posts and articles before publishing

How it works
The tool counts whitespace-separated words in your text and divides by 220 words per minute (the established average adult reading speed for general content). The result is rounded up to the nearest whole minute. For texts under 220 words, the result shows "1 min" — the practical minimum reading time estimate.

Frequently Asked Questions
Common questions about this tool.
Why 220 words per minute? ▼
220 wpm is the widely accepted average for adult silent reading of general content. Research (Trauzettel-Klosinski & Dietz, 2012) puts the range at 200–250 wpm for most adults. Use 150–180 wpm for technical or scientific content when estimating for specialist audiences.
How do I add reading time to my blog automatically? ▼
Calculate it programmatically with: Math.ceil(wordCount / 220) + " min read". Count words by splitting on whitespace: text.trim().split(/\s+/).length. Both operations work in any JavaScript environment.
What is the difference between Reading Time Calculator and Word Counter? ▼
They share the same underlying logic — both count words and estimate reading time. Reading Time Calculator focuses on the time estimate. Word Counter also shows character count and line count. Use whichever URL you remember more easily.
Is Reading time calculator free to use? ▼
Yes. Reading time calculator is completely free and runs locally in your browser — no account required.
Does Nadhebe upload my data? ▼
