Book Length & Writing Goal Planner

Free novel writing planner. Convert manuscript word count into a personalized daily writing target, deadline, and estimated print page count across formats (5×8 paperback, 6×9 hardcover, standard Kindle). Includes weekly-schedule customization for NaNoWriMo and serial authors.

When to use this

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.

How it compares

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.

How it works

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".

FAQs

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.

Worked example

Input

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

Output

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.

Common pitfalls

  • 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.
