Equilibrium
Balance, disruption, a new balance.
A story can be read through the changes in its world’s balance. A disruption unsettles an existing state, efforts to respond reshape the situation, and a different equilibrium emerges. This approach helps you compare what was possible at the beginning with what becomes possible at the end.
How it works
Tzvetan Todorov, a Bulgarian-French theorist, treated narrative as the passage from one equilibrium to another in Grammaire du Décaméron (1969) and The Poetics of Prose (1971). A balanced state is disrupted, and the effort to repair it ends in a new balance. Todorov’s own model has three parts. The five stages taught today, common in media studies courses because they are so clear, are a later expansion of it.
Equilibrium (0–10%) is the stable, balanced state where the story begins. Disruption (10–20%) is the event that upsets it. In Recognition (20–30%) the characters realize something is wrong, and Attempt to Repair fills the long stretch from 30% to 85% with efforts to undo the damage, which often fail at first. New Equilibrium (85–100%) is a changed, stable state, the world settled on new terms.
The first three stages track the shared moments closely, with Disruption near the common inciting incident and Recognition straddling the usual commitment at 25%. After that the model marks nothing until 85%, so the midpoint and the lowest point both sit inside the repair. Snyder’s beat sheet names several beats in that same stretch, including its Midpoint and All Is Lost. Todorov’s attention stays on the state of the world, which makes the model a sharp tool for analysis. Truby’s final step is also called New Equilibrium, though it measures the hero’s inner level.
Todorov’s compact shape works well for pieces with little room, and for diagnosing a finished draft. A good test is to write the opening and closing equilibriums side by side and list the differences; if the list is short, the ending needs more consequence. Recognition deserves its own scene, since the moment characters grasp the problem is often where an audience starts to care. In anything longer, the Attempt to Repair needs internal shape borrowed from another model, because Todorov leaves that span open.
The framework, part by part
Positions are illustrative comparison references, not universal timing rules.
- Equilibrium (0%–10%, Ordinary world): A stable, balanced state.
- Disruption (10%–20%, Inciting incident): An event upsets the balance.
- Recognition (20%–30%, Commitment): The characters realize something is wrong.
- Attempt to Repair (30%–85%, New world): Efforts to undo the damage, which often fail at first.
- New Equilibrium (85%–100%, New normal): A changed, stable state.

Watch for
The new equilibrium has to differ from the first, or the story stood still.

A short film on every structure
Each of the 30 structures has a 90-second animation that draws its shape beat by beat, and a page with every beat, how its parts work, questions to try, and when it can help. Start with one you’ve heard of.
All 30 structures on one timeline
Each row is one structure. The story runs left to right, from the first page (0%) to the last (100%). Bars are beats that last a while; diamonds are single moments. Drag the red line to any point, and the list below shows the nearby beats in each structure.
- Bar: a beat that lasts a while
- Diamond: a beat at one moment
- Red line: the point you’re reading
- A blank stretch: that structure names no beat there
- Act II-A and II-B are the two halves of Act Two, split at the midpoint.
Rows 1 to 13 follow Robert Carlson’s Ultimate Story Structure Chart (2015). Rows 14 to 21 are the structures readers of that thread asked him to add, and rows 22 to 30 are nine more we added. Positions combine source conventions and editorial estimates. Use them to compare approaches; they are not universal timing rules.

Outline your story in any structure
Choose a framework and give its prompts a few sentences. Compare suggested placements in other frameworks to find a useful question or a different way to develop an event.

Write a sentence for each beat
A beat is one turn in the story, like the Catalyst that knocks your hero’s life off course. Each beat comes with a question to help you answer it.
Compare another framework
The comparison suggests where your notes could fit. Review each match. You decide which prompts matter to your story.
We wrote The Wonderful Wizard of Oz as a Save the Cat! outline. These excerpts from our outline of Baum’s 1900 novel show how suggested placements change between frameworks. Unmapped prompts describe this partial outline, not a flaw in Oz. Pick any structure you know and try it with your own story.
Sketch your story’s ups and downs
Kurt Vonnegut drew stories as a line that rises when things go well for the main character and falls when they go badly. Draw yours from left to right and we’ll name the classic shape it’s closest to.
