What pacing actually is
Scene length, how often scenes turn over, the balance of action to dialogue, and when new voices arrive. All four are measurable from the page. None of them is a grade.
Industry Practice desk · Aug 19, 2026
Page count tells a reader how long a draft is. Pacing is how that length is distributed — where the scenes are, how long they run, where the action share dips, and how late the cast keeps arriving. Two 105-page screenplays can be nothing alike.
This desk shows what published practice actually looks like across 2,077 feature screenplays, then lets you place your own draft on the same measure — in your browser, without uploading it.
Scene length, how often scenes turn over, the balance of action to dialogue, and when new voices arrive. All four are measurable from the page. None of them is a grade.
A reader who says a draft "drags in the middle" is describing distribution, not length. Cutting pages evenly does not fix an uneven shape — it just makes a shorter version of the same problem.
Every number here is counted from your pages against published practice. Nothing guesses where your inciting incident sits — that is a reading you make, and a tool that claims to detect it from word positions is guessing.
Published practice
Advice pages describe the three-act shape in pages. That framing assumes every part of a screenplay is made of the same material. Measured across 2,077 features, it is not: the action share peaks at the opening and the ending and dips through the middle. Action still outweighs dialogue at the midpoint — the difference is how far it leads.
Every screenplay in the corpus is normalized to 100% of its own action-and-dialogue words, then cut into ten equal stretches. Two things move in opposite directions: action dips through the middle and rises at both ends, while the speaking cast keeps arriving long after the opening.
Axis starts at 40% — the median and the middle half sit inside a narrow window. The p10 and p90 tails run past both ends and are deliberately not drawn; widening the axis to cover them flattens the shape this panel exists to show.
Cumulative, on the full scale.
| Stretch | Action share | Action middle half | Cast arrived | Cast middle half |
|---|---|---|---|---|
| 0–10% | 63.8% | 53%–74% | 22% | 16%–28% |
| 10–20% | 55.7% | 44%–66% | 36% | 29%–44% |
| 20–30% | 55.1% | 45%–67% | 47% | 39%–56% |
| 30–40% | 54.7% | 44%–66% | 56% | 48%–65% |
| 40–50% | 54.5% | 43%–65% | 65% | 57%–73% |
| 50–60% | 54.5% | 44%–66% | 73% | 66%–80% |
| 60–70% | 55.7% | 45%–67% | 81% | 74%–87% |
| 70–80% | 56.3% | 44%–68% | 88% | 82%–93% |
| 80–90% | 59.9% | 47%–73% | 94% | 91%–97% |
| 90–100% | 66.1% | 54%–78% | 100% | 100%–100% |
Read the cast-arrival panel too. Only 22% of a screenplay's speaking characters have their first speaking scene inside the first tenth, and 65% by the midpoint. A draft that introduces its whole cast inside the first fifth is not following practice — it is asking a cold reader to hold every name at once.
Scene rhythm
Across the corpus, the longest tenth of a screenplay's scenes carries a median 38% of the whole draft, and 29% of scenes carry no dialogue at all. Concentration and silence are normal. What they are not is uniform.
Each ribbon holds the same narrative words, cut into 40 scenes. The only thing that changes is how much of the draft its longest tenth of scenes carries — the range published across 2,077 screenplays. A word count cannot tell these three apart. A reader can, by the second act.
Even pulse
Longest tenth carries 32% · 10th percentile
The longest tenth carries a relatively small share of the draft, so scene lengths are comparatively even.
Typical
Longest tenth carries 38% · Median
The middle-of-corpus shape: mostly short and medium units with a handful of longer scenes.
Set-piece driven
Longest tenth carries 46% · 90th percentile
The longest tenth carries close to half the draft, concentrating much more narrative weight in a few scenes.
Your draft
Paste Fountain or open a Final Draft file. It is parsed here, in this tab, using the corpus's own definitions of narrative words, scene midpoints and first speaking scene — with one Final Draft exception noted in the method below. Nothing is uploaded, and no verdict is produced.
The tool also lives at /tools/pacing-map.
How to use it
Look for three things together: few scene changes, even scene lengths, and an action share below the corpus band. That is a structural combination, not a diagnosis — what it means in your draft is a reading only you can make, because word counts cannot tell a fast confrontation from a slow explanation. The three numbers point at a stretch; the answer is in one of its scenes, not in the word count.
If your cast-arrival line runs well above the corpus band in the first two tenths, the draft is front-loading names. Practice spreads them. Consider whether a speaking part in the first tenth of the words could arrive later, or stay silent.
Published endings get more action-heavy, not less — a median 66.1% in the final tenth. A closing stretch that dips into dialogue is running against that grain. Sometimes that is the film. The split counts words in action blocks against words in dialogue, and an action block can be a fight or a description of the weather — which one your ending needs is the part only you can read.
If every segment in the scene rhythm is nearly the same width, the draft has one gear. Published screenplays vary: short units to move, long units to land. Give the scene that matters most the room the measurement says it usually gets.
Method and limits
The corpus is MovieSum, analysed 2026-08-10 across 2,077 screenplays that met inclusion thresholds for scene count, narrative words, speaking characters, and dialogue blocks. Every screenplay carries equal weight. Progress is measured in narrative words — action plus dialogue — not pages, because the corpus never stored pagination. Each scene is assigned to the tenth containing the midpoint of its own word span, so a long scene is counted once rather than smeared across the stretches it covers. Medians carry bootstrapped 95% intervals.
The pacing map applies those same definitions to your draft, with one exception worth knowing about. Final Draft carries paragraph types the corpus format did not distinguish — Shot, Cast List, New Act and General — and the importer folds all four into action, so their words count toward both the action share and the narrative total. The corpus counted only scene description as action, and left its own shot elements out of both. A Final Draft file that leans on those paragraph types will therefore read more action-heavy here than the same pages would have inside the corpus. Fountain drafts are unaffected: the format has no equivalent markers.
Where the two sides cannot be compared at all, the readout says so: a draft below the corpus thresholds is placed with an explicit notice, and per-tenth scene counts are withheld for anything that is not feature-scale, because the corpus band comes from features and would otherwise just restate your total length ten times.
What none of it can do is name a beat. Where an inciting incident sits, whether a midpoint turns, whether a long scene earns its length — those are readings a person makes from the text. This desk measures where the words are. Deciding what they mean is the work.

Then make the cut
Plot keeps a save point before the pass, so a tighter middle never costs you the version that worked. Try the cut on one scene as a take, compare it against the original, and incorporate it only if it reads better. Free plan, full editor.
