Frequently Asked Questions
Q: How is the reading time calculated?
A: It is calculated based on the average adult reading speed of about 250 characters per minute (excluding spaces), precisely converted down to seconds.
Q: Does it work well for non-Korean texts?
A: While optimized for Korean average reading speeds, the logic uses the raw character length, so it provides a very reasonable estimate for English and other languages as well.
Q: Is my text data saved anywhere?
A: No. All calculations are performed instantly on your device (Client-side). The text you input is never sent to or stored on any server.
Q: How does the WPM slider work?
A: WPM stands for Words Per Minute — how many words you read in one minute. Drag the slider between 50 and 600 to see your reading time update instantly. Use the preset buttons (Slow 100 / Average 200 / Fast 300 / Expert 450) for quick settings.
Q: How do I use the Teleprompter mode?
A: Enter your text, then click 'Practice with Teleprompter'. Your text will auto-scroll at exactly the pace of your calculated reading time. Press Space to pause/resume, Esc to exit, and use the speed buttons (0.75×–1.5×) to adjust the scroll rate.
Q: What is the Readability Score?
A: The Readability Score uses the Flesch Reading Ease algorithm — it analyzes average sentence length and syllables per word to produce a score from 0 to 100. Higher scores mean easier reading. A score of 60–80 is generally considered the sweet spot for SEO-friendly blog content.
Q: What blog post length is best for SEO?
A: For informational blog posts, 7–12 minutes of reading time (roughly 1,400–2,400 words) tends to perform best in Google search rankings. However, what matters most is matching the reader's search intent — not word count alone. Use this calculator to set a target reading time and write to fit it.
Q: Does it work on mobile devices?
A: Yes — the tool is fully responsive and works seamlessly on smartphones and tablets. The Teleprompter mode also supports mobile full-screen.
