How Reading Time is Calculated

Reading time is estimated by dividing word count by the average adult silent reading speed. Research by Rayner et al. (2016) puts average adult reading speed at 200–250 words per minute for non-technical prose. This tool defaults to 225 wpm as a middle estimate, but you can adjust it in Settings to match your audience's typical reading pace.

Formula: Reading time = Word count ÷ Reading WPM

Speaking Time

Speaking time defaults to 130 words per minute, which reflects a measured conversational delivery appropriate for presentations, lectures, and podcasts. Native speakers in casual conversation average 140–160 wpm, but presenters typically speak more slowly for clarity.

Formula: Speaking time = Word count ÷ 130 wpm

Keyword Density Explained

Keyword density is the percentage of times a word appears relative to total word count. The keyword density panel shows your top 10 most-used content words, excluding common stop words (articles, prepositions, conjunctions like "the", "a", "and", "is"). For SEO, keeping your target keyword at 1–3% is generally considered healthy — below 1% is under-optimized, above 3–4% risks over-optimization flags.

Frequently Asked Questions

How is reading time calculated?
Reading time is word count ÷ 225 words per minute (adjustable in Settings). For example, a 900-word article = approximately 4 minutes. The 225 wpm figure is a commonly cited average for adult silent reading of general prose.
How is speaking time calculated?
Speaking time uses 130 words per minute by default, reflecting a measured presentation pace. A 650-word speech takes about 5 minutes. Adjust in Settings if your delivery style is faster or slower.
What is Twitter's character limit?
Twitter/X has a 280-character limit for standard accounts. URLs always count as 23 characters regardless of actual length. Media attachments do not count against the character limit.
How long should a meta description be?
Keep meta descriptions under 155 characters to avoid truncation in Google search results. Meta titles should be 50–60 characters. The progress bars in the Social Platform Limits section track both.
What is keyword density?
Keyword density is the percentage of times a specific word appears relative to total word count. The top-10 table excludes common stop words. SEO best practice is 1–3% for primary keywords.
