An experienced writer working from a clear outline produces 500–800 words per hour of focused writing. Most drafts therefore take 1.5–2 hours per 1,000 words, plus separate time for revision. New or struggling writers may take 2–3× longer; pros with a clear topic and outline can hit 1,200+ words per hour.
Use the Pomodoro timer to structure focused writing sprints — typical output is one section per 25-minute Pomodoro.
