Triple the Impact: Use the Rule of Three

Hi Reader,

The Rule of Three is a storytelling technique that makes writing more engaging, memorable, and impactful. (See! I used three adjectives.) It works because three is the perfect balance. One feels incomplete, two feels like a coincidence, but three? Three is a pattern, a rhythm, a satisfying payoff. Why does this work? Because humans are wired for patterns, and three is the smallest number that creates a full-fledged pattern. It builds expectation and then delivers on it.

Let’s dive into the Rule of Three and how you can use it in your writing.

The Power of Three in Story Structure

For screenwriters and novelists, the classic three-act structure (Beginning, Middle, End) is the foundation of storytelling. Act One sets up the world and problem. Act Two complicates everything. Act Three delivers the resolution. It’s storytelling in three neat parts.

💡 Try this: When structuring your story, think in threes. Give your protagonist three major obstacles to overcome. Have their character arc evolve in three key moments. Use three emotional beats to deliver that gut-punch ending.

The Power of Three Protagonists

Storytelling loves a good trio. Three examples:

1. Harry, Ron, and Hermione – Harry Potter Series

2. Luke Skywalker, Princess Leia, and Han Solo – Star Wars Original Trilogy

3. The Three Musketeers: Athos, Porthos, and Aramis – The Three Musketeers

Trilogies

We see the rule of three in the popularity of trilogies. We love a good story with three parts.

The Lord of the Rings

The Fellowship of the Ring (2001)
The Two Towers (2002)
The Return of the King (2003)

2. The Godfather

The Godfather (1972)
The Godfather Part II (1974)
The Godfather Part III (1990)

3. The Dark Knight

Batman Begins (2005)
The Dark Knight (2008)
The Dark Knight Rises (2012)

The Rule of Three in Comedy

Like we talked about with witty banter, comedy loves the Rule of Three because it sets up an expectation—and then subverts it for laughs. The first two items in a sequence establish a pattern, and the third surprises.

“I came, I saw, I… forgot what I was doing.”
“She’s smart, she’s charming, and she once tried to order a taco at a bank drive-thru.”
"For our picnic, we packed sandwiches, fruit, and a live chicken."

Think about classic comedic sequences: a character tries to do something and fails twice before succeeding—or failing spectacularly. It’s why slapstick works in three beats. The first two build anticipation; the third flips it on its head.

💡 Try this: If you’re writing humor, use a list of three with a twist on the third. Play with expectations and reversals to keep your readers laughing.

The Rule of Three in Dialogue

Ever notice how the best lines in movies and books often come in threes? It creates a rhythm that sticks in the audience’s mind.

Jaws: “You’re gonna need a bigger boat.” (Three parts: You’re gonna / need / a bigger boat.)
Julius Caesar: “I came, I saw, I conquered.”
The Dark Knight: “Some men just want to watch the world burn.”

The Rule of Three in Description

In description, three is the magic number:

“Her dress was red, flowing, and impossible to ignore.”
“He had a voice like gravel, whiskey, and bad decisions.”
“The house was rambling, ramshackle, and ivy-covered.”

The Rule of Three in Pacing & Repetition

Repetition is powerful. It’s why speeches, slogans, and mantras use three.

“Location, location, location.”
“Stop, drop, and roll.”
“Blood, sweat, and tears.”

💡 Try this: When writing dialogue or descriptions, test out the Rule of Three. It adds balance, impact, and memorability.

Triple Your Writing Power

The Rule of Three isn’t just a gimmick—it’s a time-tested technique that makes stories more compelling, humor funnier, and messages more memorable. So next time you’re stuck, ask yourself: Can I use the Rule of Three in this moment?

Now go forth and write in threes—because one isn’t enough, two is close, but three? Three is just right.
