Reading Time Calculator

What is the Reading Time Calculator?

Estimate how long a text takes to read silently or aloud. Reading time estimates help writers set expectations for blog posts, newsletters and speeches before anyone starts reading.

How to use the Reading Time Calculator

1. Paste or type your your text into the box (a sample is pre-filled so you can see how it works).
2. Results update automatically as you type; you can also press Calculate.
3. Read the output: reading time, speaking time (150 wpm), words.
4. Use the 📊 chart to see the result visually, then copy or share it.

Formula and method

Worked example

With reading speed = 238 wpm, the Reading Time Calculator returns reading time: 0:10 (min:sec); speaking time (150 wpm): 0:15 (min:sec); words: 38.

Where the Reading Time Calculator helps in real life

A blogger adds “6-minute read” to the top of an article so readers know what to expect. Pasting the text gives a time based on average silent reading speed.

A speaker preparing a 5-minute talk checks whether the script fits. The speaking-time estimate shows whether to cut a few paragraphs.

Common mistakes to avoid

• Using silent reading speed to time a speech.
• Ignoring images, tables and code that slow readers down.
• Rounding reading time down to make posts seem shorter.
• Assuming every reader moves at the average pace.

💡 Practical tip: Spoken delivery is much slower than silent reading, so a speech always takes longer than its reading time suggests.

Tips for better results

• Round up to the next minute when displaying reading time.
• Rehearse speeches aloud to confirm the estimate.
• Split very long articles with clear headings.
