What this volume looks like

Equivalent to exactly 50 sheets of 400-square manuscript paper

Text with more kanji looks denser on the page, while hiragana-heavy text looks lighter. The same 20,000 characters can feel quite different, so check the kanji ratio too (the character counter measures it).

How these numbers are calculated

Manuscript paper: 20,000 characters ÷ 400 = 50 sheets. Lines are counted at 20 characters per line, rounded up — the same basis as this site's character counter.
A4: converted at a common word-processor layout of 40 characters × 36 lines (1,440 characters per page). Actual page counts vary with margins, font and line spacing.
Reading aloud: calculated at 300 Japanese characters per minute (the same basis as the counter's speech-time display).
Silent reading: calculated at 500 Japanese characters per minute (the same basis as the counter's reading-time display).

Where 20,000 characters shows up

A full-scale volume, comparable to a thesis chapter, a booklet or a short story.
