A short film beat sheet keeps five of the classic fifteen beats: Opening Image, Catalyst, Midpoint, Climax and Final Image. The other ten get merged or cut. On 10 pages that means a turn roughly every two pages, one story engine, no B story, and an ending that lands as an image rather than a resolution scene.
That is the whole method in one paragraph. The rest of this guide shows the beat-by-beat compression map, the page targets for 5, 10 and 15-page shorts, and the specific ways compression goes wrong when writers treat a short like a miniature feature.
Why fifteen beats break a ten-page script
The fifteen-beat model was built for features. Blake Snyder's page numbers assume a 110-page document, and the full 15-beat breakdown with page numbers spaces those beats seven pages apart on average. Run the same math on a 10-page short and you get a beat every two-thirds of a page.
Nobody can write that script. A beat needs room to land: a scene, or at least a full moment inside a scene. Fifteen landings in ten pages produces a story that turns before any turn has weight, and reads like a summary of a film rather than a film. I have read contest shorts built this way, and you can feel the writer checking boxes by page 3.
The fix is not to space the fifteen beats closer together. It is to admit that most of them exist to manage a feature's second act, and a short film does not have a second act worth managing. A short has one dramatic question, one turn that complicates it, and one answer. Everything else is compression overhead.
The five beats a short cannot lose
Strip the feature model down to load-bearing walls and five beats remain. These are the ones that survive at any length, from a 5-page festival short to a 15-page proof of concept.
Opening Image. The first thing on screen states the world and the problem in one picture. In a short this beat works harder than anywhere else, because you have no set-up pages to recover a vague opening. It belongs at the top of page 1 and nowhere later.
Catalyst. The event that breaks routine. In a feature it waits until page 12; in a 10-page short it belongs on page 1 or 2. A short that spends three pages establishing normal life before anything happens has already spent thirty percent of its runtime on throat-clearing.
Midpoint. One reversal that changes what the protagonist wants or what the audience understands. Page 5 of 10. This is the beat writers cut first and it is the wrong cut: without it, the short becomes a single event stretched across ten pages, and the middle sags exactly the way a feature's second act sags, just faster.
Climax. The protagonist acts, and the action answers the dramatic question. Pages 8 to 9 in a 10-page script. In a short the climax is usually a decision made visible, not a sequence.
Final Image. The closing picture answers the Opening Image, same frame, changed meaning. Shorts live or die on this rhyme because there is no falling action to soften an ending that misses. It closes page 10.
The compression map, beat by beat
Here is what happens to each of the fifteen feature beats when the document shrinks to 10 pages. Keep means the beat gets its own moment. Merge means it shares a scene with another beat. Cut means it disappears entirely, and the story is better for it.
| Feature beat (110 pages) | In a 10-page short | Page target |
|---|---|---|
| Opening Image | Keep | Top of page 1 |
| Theme Stated | Merge into the opening scene, implied not spoken | Page 1 |
| Set-Up | Compress to a few lines around the Catalyst | Page 1 |
| Catalyst | Keep | Page 1-2 |
| Debate | Cut, or one beat of visible hesitation | Page 2 |
| Break into Two | Merge with the Catalyst; the short commits immediately | Page 2 |
| B Story | Cut | Nowhere |
| Fun and Games | Becomes the escalation stretch | Pages 3-4 |
| Midpoint | Keep | Page 5 |
| Bad Guys Close In | Compress into one complication | Pages 6-7 |
| All Is Lost | Merge with the low point into a single moment | Page 7-8 |
| Dark Night of the Soul | Cut, or a single wordless image | Page 8 |
| Break into Three | Merge with the Climax decision | Page 8 |
| Finale | Keep, as the Climax | Pages 8-9 |
| Final Image | Keep | Page 10 |
Two patterns worth noticing. Every cut beat is an interiority beat: Debate, B Story, Dark Night of the Soul. Features use those to let the audience breathe and to test the theme from a second angle. A short tests its theme once, through the main line, and trusts the audience to keep up.
And every merge collapses a transition into the event next to it. Features separate the Catalyst from the commitment because a feature protagonist can refuse the call for ten pages. A short film protagonist commits in the same scene, often in the same look.
If you want to see the uncompressed version of this grid filled in for a feature, the 110-page filled example shows all fifteen rows doing their separate jobs, which makes the contrast obvious.
Scaling the map for 5 and 15 pages
Page counts for shorts track runtime almost one to one, with far less slack than features get, as covered in the short film script length guide. The five-beat spine scales cleanly across the common lengths.
| Beat | 5-page short | 10-page short | 15-page short |
|---|---|---|---|
| Opening Image | Page 1, first quarter page | Top of page 1 | Top of page 1 |
| Catalyst | Page 1 | Page 1-2 | Page 2-3 |
| Midpoint | Page 2.5 | Page 5 | Page 7-8 |
| Climax | Page 4 | Page 8-9 | Page 12-13 |
| Final Image | Page 5 | Page 10 | Page 15 |
At 5 pages, beats stop being scenes and become moments inside what is often a single continuous scene. At 15 pages you gain enough room to restore one compressed beat to full size, and my strong recommendation is to spend that room on the complication stretch before the Climax, not on set-up. Set-up is the first thing festival programmers skim and the last thing they miss.
To check your own draft, run the percentages rather than the page numbers: Catalyst inside the first 15 percent, Midpoint at 50, Climax between 80 and 90. The free beat sheet calculator does this arithmetic for any page count, and it works for a 7-page short exactly the way it works for a feature.

Start FreeOne idea, one turn: what replaces the B story
The hardest habit to drop when moving from features to shorts is the second storyline. Features need a B story because the theme has to be argued from two sides across two hours. A short argues it once.
What replaces the B story is a single strong irony between the Opening and Final Image. The character who spends page 1 building a wall spends page 10 opening a door. That rhyme does the thematic work a feature would assign to a whole subplot, and it costs zero pages.
This is also why shorts with two protagonists so often run long and land soft. Two protagonists means two arcs, two arcs mean two sets of beats, and the compression math that barely fits one story now has to fit two. If your short needs two full arcs, it is usually a feature idea wearing a short film's clothes. The same diagnosis applies in the other direction, and the pilot versus feature comparison makes a similar point about format mismatches: the structural unit has to match the container, or the container wins.
Where compression goes wrong
Four failure modes account for most broken short film beat sheets I see in feedback swaps and contest reads.
The delayed catalyst. Three pages of a character's morning routine before anything breaks. In a feature that is a slow open; in a short it is a third of the film gone. If your Catalyst sits past page 2 of 10, cut from the front until it does not.
The missing midpoint. The short sets up a situation, then resolves it, with nothing in between that changes the terms. This produces the "sketch" feel, a premise stretched rather than a story told. One reversal at the halfway mark fixes it, and the reversal can be as small as a new piece of information that changes what the protagonist's goal costs.
The feature ending. Two pages of aftermath after the Climax, tying off every thread. Shorts end at the turn, not after it. If your Climax lands on page 8 and the script runs to page 12, the last four pages are almost always the writer reassuring themselves.
The beat checklist. All fifteen feature beats crammed in at two-thirds of a page each. This is the failure the compression map above exists to prevent. The tell is dialogue that announces structure: someone states the theme out loud on page 1 because Theme Stated is on the list. Snyder himself, on savethecat.com, treats the beats as story functions rather than a fill-in form, and functions can share scenes.
A pre-draft checklist for your short film beat sheet
Run this before writing pages. Every unticked box is a structural rewrite that costs less now than it will after a draft exists.
- The Opening Image and Final Image describe two versions of the same picture
- The Catalyst lands inside the first 15 percent of the page count
- There is exactly one midpoint reversal, and it changes what the protagonist wants or what we know
- There is no B story, and no second protagonist carrying a separate arc
- The Climax is a visible decision or action, not an offscreen realization
- The script ends within a page of the Climax
- Each beat names an event, not a mood
- The page targets hit the percentages: Catalyst by 15, Midpoint at 50, Climax by 90

FAQ
How many beats does a short film need?
Five: Opening Image, Catalyst, Midpoint, Climax and Final Image. The other ten beats of the feature model either merge into these five or get cut. A 15-page short can afford to restore one compressed beat, usually the complication stretch before the Climax.
Can I use the Save the Cat beat sheet for a short film?
As a starting vocabulary, yes; as a fifteen-row document, no. The page numbers assume 110 pages and the beat count assumes a second act that shorts do not have. Compress it using the map above, keeping five beats and merging or cutting the rest.
Where does the midpoint go in a 10-page short?
Page 5, or as close to the 50 percent mark as your scene breaks allow. The midpoint is a reversal that changes the terms of the story, not just an escalation. Shorts that skip it read as stretched premises rather than complete stories.
Does a short film need a B story?
No, and adding one is the most common structural mistake in short scripts. The thematic work a feature assigns to its B story gets done in a short by the rhyme between the Opening Image and the Final Image. If the idea genuinely needs a second storyline, it is probably a feature idea.
How long should each beat be in a short film?
The Opening and Final Images are moments, a quarter page each. The Catalyst and Midpoint each earn a short scene. The Climax gets the longest run, one to two pages in a 10-page script. Everything between beats is connective escalation, and it should total less space than the beats themselves.
Do festival readers actually care about structure in shorts?
They care about the symptoms. A late catalyst, a sagging middle and an ending that trails past its climax are the three most common reasons shorts get passed on in the first read, and all three are beat placement problems. Readers rarely name the missing beat; they name the boredom it causes.
