# Reading Time Calculator

- **URL:** https://codeasystem.com/calculators/education/reading-time-calculator/
- **Category:** education
- **Description:** Estimate how long any text takes to read from its word count, using research-backed average reading speeds.
- **Primary output:** Estimated reading time: 5 min 3 sec

## Inputs
- Word count (name: `words`, type: number, example: 1200)
- Reading speed (name: `wpm`, type: number, example: 238)

## Outputs
- Estimated reading time: 5 min 3 sec
- In minutes: 5.04
- Pace used: 238 words per minute

## Formula / methodology
```
Minutes = word count ÷ reading speed (wpm)
```

Divide the word count by reading speed in words per minute. The default of 238 wpm comes from a large 2019 meta-analysis of silent reading rates in English; slow proofreaders run near 150 wpm while speed readers exceed 400.

## Assumptions & limitations
- Average adult silent reading in English at about 238 wpm unless customized.
- Technical, dense or foreign-language text reads slower.
- Formatting, images and headings are ignored; pure prose pace.

## How to use
1. **Count the words**; Paste into the word counter or read the count from your editor.
2. **Pick a realistic speed**; Keep 238 for casual reading; drop toward 150 for dense material.
3. **Plan the time block**; Round up and add slack for notes or re-reads of tricky passages.

## Example
A 1,200-word article takes the average reader just over five minutes at 238 wpm.

Result for these inputs:

```
Estimated reading time: 5 min 3 sec
```

## About this calculator
### Where 238 comes from

Marc Brysbaert’s 2019 meta-analysis pooled hundreds of studies and landed on 238 wpm for silent English reading; a far sturdier figure than the folk 200–250 range. It is now the standard default for reading-time estimates.

### Content type shifts everything

Skimmable listicles fly; legal contracts crawl. Readers self-adjust speed to difficulty, which is why a manual override beats any universal constant when stakes are real; billable hours, exam prep, podcast scripts.

### Why blogs show “x min read”

Medium popularized the badge and engagement followed: telling readers the cost upfront reduces bounce. The convention uses roughly the same arithmetic as this calculator, usually rounded to whole minutes.

## FAQs
### Is reading speed different for audiobooks?

Narration averages near 150–160 wpm, well below silent reading; a “6 minute read” becomes roughly 8 minutes listened.

### Does this work for children?

Younger readers are slower: around 150–180 wpm mid-elementary, rising toward adult speeds in the teens. Enter a lower wpm for honest estimates.

### How do I count words first?

Paste the full text into our word counter; it reports words, characters, sentences and paragraphs together.

### Why does my e-reader disagree?

Apps estimate from screenfuls and fonts rather than word counts; small differences of a minute are normal.
