Reading Time Calculator

How to Use

Paste or type your text into the input area. Reading time, speaking time, and detailed text statistics are calculated instantly as you type. The tool automatically detects whether the text is in English or Japanese and adjusts the speed accordingly.

How Reading Time Is Calculated

Reading time is estimated based on average reading speeds: 238 words per minute for English text and 500 characters per minute for Japanese text. Speaking time uses slower rates: 150 words per minute for English and 300 characters per minute for Japanese. These are averages — actual speed varies by reader and content complexity.

Common Use Cases

• Estimating article or blog post reading time before publishing.
• Preparing speeches or presentations within a time limit.
• Checking content length for social media or newsletters.
• Planning podcast scripts or video narrations.
• Evaluating reading assignments for students.

Tips

• Blog posts with a 5-7 minute reading time tend to get the highest engagement.
• A 10-minute speech is approximately 1,500 words in English.
• Technical content is typically read 20-30% slower than casual text.
• Presentations should aim for about 100-120 words per slide.
• Email newsletters perform best under 2 minutes of reading time.
