公式
Reading time (minutes) = Word count ÷ Words per minute (WPM). Standard WPM for adults: 200 WPM.
The average adult reads approximately 200-250 words per minute. The formula is straightforward: divide the total word count by the reading speed in words per minute. The result is the estimated number of minutes to read the entire article.
ステップ解説
- 1Count the total number of words in your article, blog post, or document.
- 2Determine the average reading speed (200 WPM standard for adults).
- 3Divide word count by WPM for estimated reading time.
- 4Round up to the nearest whole number for user-friendly display.
計算例
Blog post with 1,500 words, average reading speed 200 WPM
→ 1,500 ÷ 200 = 7.5 minutes ≈ 8 minutes
Scientific article with 5,000 words, average reading speed 150 WPM
→ 5,000 ÷ 150 = 33.3 minutes ≈ 34 minutes
Short article with 800 words, fast reader 250 WPM
→ 800 ÷ 250 = 3.2 minutes ≈ 4 minutes
Reference table
| Reader group | Typical WPM | Notes |
|---|---|---|
| Slow readers | 100-125 WPM | Children, ELL students |
| Average readers | 200-250 WPM | Adults, general audience |
| Fast readers | 300-400 WPM | Proficient readers, tech folks |
WPM varies depending on language comprehension, concentration, and subject familiarity.
よくある間違い
- Counting skimming as full reading — skimming is much faster (400-600 WPM) than deep reading (100-150 WPM).
- Not accounting for complexity — technical articles read slower than popular articles.
- Not subtracting for images, charts, or interactive elements — these speed up reading significantly.
活用シーン

よくある質問
Why 200 WPM as standard?
200 WPM is the average reading speed for adults in English (and similar languages). It can range from 150-250 WPM depending on the reader and content, but 200 is the best general estimate.
Does subject matter affect reading speed?
Yes, complex subjects slow reading speed significantly. Technical articles may read at 100-150 WPM, while light topics can go at 250+ WPM. Adjust your WPM assumption based on content complexity.
Does showing reading time help with SEO?
Indirectly — reading time increases user engagement (reading to the end) which improves metrics Google measures. Better user engagement signals relevance to search engines. It's also a UX improvement readers appreciate.
