Screenplay Screen-Time Estimator

無料のシナリオ上映時間推定機。「1ページ=1分」のルールをジャンルとシナリオのアクション/セリフ/括弧構成で再重み付けします。

使うべき場面

Use during script revision to predict if your 90-page script will fit a 90-minute slot — or if you've accidentally written a 2-hour epic.

他の指標との比較

Final Draft and Movie Magic give a flat page-to-minute count. This tool factors in the *kind* of pages, not just how many.

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

仕組み

Total runtime = pages × (action% × action-mult + dialogue% × dialogue-mult + pause% × pause-mult), with genre presets adjusting the multipliers.

Action and pause time inflate runtime; dialogue runs roughly 1:1 with page count.

Stunt-heavy short scripts (high action %, low page count) trigger a production-complexity warning.

よくある質問

What's the "1 page = 1 minute" rule?

A Hollywood rule of thumb. It breaks for action sequences (longer than the page suggests) and rapid comedies (shorter).

How are sliders weighted?

Action and pauses inflate runtime; dialogue is roughly 1:1. The genre selector applies a final multiplier.

Why is dialogue-heavy script faster on screen than action?

Dialogue is spoken at a fairly predictable pace close to one page per minute, while a single line of action description can represent a long visual sequence or stunt. Re-weighting the page count by the action-versus-dialogue split gives a more realistic runtime.

Does font and formatting affect the page estimate?

Yes; the one-page-per-minute rule assumes standard 12-point Courier with industry-standard margins. Non-standard fonts or spacing throw off the page count and therefore the runtime estimate.

実例

入力

90 pages, action genre, 50% action / 40% dialogue / 10% pause.

出力

Adjusted runtime: 1:48:00 (108 minutes).

The classic 1-page-per-minute rule gives 90 minutes; the action-genre multiplier inflates action blocks and shortens dialogue, landing at 108 minutes.

よくある落とし穴

  • Sliders are subjective — sit with your script and estimate honestly.
  • Multi-camera and stunt-heavy scenes vary widely.
  • Doesn't model editing pace (a fast cut can compress a "long" action block).
