How is reading time calculated?

Based on average adult reading speed: 238 words per minute for general prose, 100 for technical content, and 300+ for light fiction. The calculator lets you pick the right profile for your audience.

Does it count images or code?

Images add a small constant (about 12 seconds per image); code blocks are read more slowly (about 100 words per minute) because each line requires interpretation.

Why do blog posts show reading time?

It helps readers decide whether to commit to the article. Research shows that showing an estimated reading time lifts completion rate modestly — people prefer knowing the cost upfront.

How accurate is the estimate?

Within about 20% for most adult readers on most content. Individual speed varies wildly with content density, prior knowledge, and interest.

What's the optimal article length for engagement?

Depends on intent. SEO 'pillar content': 2,000-4,000 words for ranking on competitive keywords. Quick-answer content: 300-800 words. News articles: 400-700 words. Long-form journalism: 2,500-5,000 words. Newsletter posts: 800-1500 words. Twitter threads: 5-15 tweets. Studies show median time-on-page is ~50 seconds for articles, suggesting most readers skim. Optimal length matches reader intent: a how-to needs to be complete (whatever length); a news brief needs to be tight (300 words).

How can I increase reading speed without losing comprehension?

Practical techniques: (1) Subvocalization reduction — stop pronouncing words in your head. (2) Chunk reading — group 3-5 words at a time instead of word-by-word. (3) Use a pacer (finger or pen tracking line). (4) Skim first, deep-read second pass — gives your brain a map. (5) Practice with progressively faster materials. Speed-reading apps (Spreeder, Spritz) can train rapid serial visual presentation but research shows comprehension drops sharply above 500 WPM. Most readers improve from 200 to 300 WPM with practice — beyond that, retention suffers.

What it does

A free reading time estimator. Paste any text; get an estimated reading time based on average adult reading speed (230 words per minute by default). Adjust the WPM for slow, average, or fast readers (slow: 150 WPM, fast: 400 WPM, technical: 100-150 WPM).

Useful for blog post previews, course content, or planning how long a chapter will take. Comprehension drops if you speed past 300-400 WPM, so faster isn’t always better. Studies show that displaying an estimated reading time on articles modestly increases completion rate — readers prefer knowing the time cost upfront before committing. Most popular blogs (Medium, Substack, NYT) display it for this reason.

Reading time conventions: blog posts typically run 800-1500 words (about 4-7 minutes), news articles 300-700 words (1.5-3 minutes), pillar SEO content 2000-4000 words (9-17 minutes). For audiobook narration, plan 130-150 words per minute (much slower than silent reading because of pauses, voice clarity, and listener processing). For presentations, plan 110-130 WPM with slides — even slower for technical content.
