Book Length & Writing Goal Planner

無料の小説執筆プランナー。原稿の単語数を個人化された日次執筆目標、締切、推定印刷ページ数に変換します。

使うべき場面

Use when starting a novel, planning a NaNoWriMo run, or recalibrating mid-project after a hiatus. Switching between deadline and daily modes shows you both views.

他の指標との比較

Spreadsheet-based planners cover similar math but require setup. This tool fits the same workflow into a one-screen calculator.

Enter your values below. Calculations run locally as you type.

仕組み

Word counts are converted to print pages using genre-standard words-per-page (300 for 6×9 trade, 350 for mass-market, 250 for Kindle).

In deadline mode the target daily rate is computed from days remaining; in daily-target mode the finish date is projected from your sustainable rate.

Reading time is estimated at 250 wpm — a generous "average adult".

よくある質問

How accurate are the words-per-page figures?

Industry averages: ~300 words per trade paperback page, ~250 for Kindle, ~350 for mass-market paperback. Real layouts vary with font and margins.

Should I write every day?

Not necessarily. Pick your real schedule — the planner adapts the daily target to your selected days.

Why is my deadline more aggressive than my daily target?

Deadline mode overrides the daily target with the rate needed to hit the deadline. If you can't sustain that, switch to daily mode and accept a later finish.

実例

入力

Target 80k words, current 12k, writing 5 days/week at 1,000 words/day.

出力

Finish in ~14 weeks. Estimated 267 print pages.

68,000 words remaining ÷ 5,000 words/week = 13.6 weeks. 80,000 ÷ 300 words/page = 267 pages in a standard 6×9 trade paperback.

よくある落とし穴

  • Words-per-page is an average — actual layout varies by font, margins, dialogue density.
  • Reading time uses 250 wpm — slower readers will take longer.
  • Doesn't account for revision passes — first draft only.
