Reading Time for Post / Page

Hi,

I was going through Ghost Github source code , I’m curios about how reading_time is calculated .
It might be off the topic, any references to the util function used will be really helpful

thanks
Raj

Hey @RajNandigalla

You can see the reading time logic here:

github.com

TryGhost/Ghost-SDK/blob/master/packages/helpers/lib/utils/reading-minutes.js

import countImages from './count-images';
import countWords from './count-words';

export function estimatedReadingTimeInMinutes({wordCount, imageCount}) {
    const wordsPerMinute = 275;
    const wordsPerSecond = wordsPerMinute / 60;
    let readingTimeSeconds = wordCount / wordsPerSecond;

    // add 12 seconds for the first image, 11 for the second, etc. limiting at 3
    for (var i = 12; i > 12 - imageCount; i -= 1) {
        readingTimeSeconds += Math.max(i, 3);
    }

    let readingTimeMinutes = Math.round(readingTimeSeconds / 60);

    return readingTimeMinutes;
}
