How to Write Flash Fiction: A Practical Guide From a Working Writer
A guide to writing flash fiction that actually works. Not theory. Not rules borrowed from a textbook. What I have learned from twenty years of writing compressed fiction on trains, in borrowed rooms, and in cities I was passing through.
Flash fiction is not a short story that has been cut down. It is not a scene from a novel. It is not a prose poem with a plot bolted on. And it is not, despite what the internet will tell you, simply “a story under 1,000 words.”
Start with what flash fiction is not
Flash fiction is a complete piece of fiction, with characters, tension, and resolution, that achieves its effect through compression rather than expansion. Every sentence is load-bearing. Nothing is decorative. If you can remove a line and the story still stands, the line should not have been there.
I have been writing flash fiction for twenty years. Published in Adelaide Magazine, Litro, Cleaver Magazine, Poetry Scotland, White Wall Review, and others. One story shortlisted for a Pushcart Prize.
The first line does everything
In a novel you have chapters to build a world. In flash fiction you have one sentence. If the first line does not create a question in the reader’s mind, they will not read the second.
The question does not need to be dramatic. It needs to be specific. It needs to imply a world that exists beyond the page.
“It was a cold day and she was sad.” — tells us nothing. Compare with:
“She wore his coat to the funeral because hers was still at his flat.”
That is a world. We know the relationship ended. We know she is grieving. We know all of this from one sentence.
Your first line should make the reader feel as though they have walked into a room where something has already happened. Start in the middle. The backstory is implied by what the characters do, not by what the narrator explains.
Write the ending first
The best flash fiction starts with the last line. If you know where the story lands, every sentence becomes a step toward that landing. Nothing wanders.
The ending is not a twist. It is a resonance — the moment where everything the reader has absorbed suddenly vibrates at a different frequency. See How to End a Flash Fiction Story for a deeper look at resonant endings.
Cut the first paragraph
Write the story. Then delete the first paragraph entirely. Nine times out of ten, the story is better without it.
First paragraphs in early drafts are throat-clearing. The writer is warming up. By the second paragraph the writer has arrived. Everything before was scaffolding.
One character, one situation, one shift
Flash fiction does not have room for subplots. The form works best when it focuses on one person in one situation, and then something shifts.
The shift does not need to be an event. It can be a realisation, a memory surfacing, a detail noticed for the first time. If your flash fiction has more than two named characters, ask whether every one is essential.
Show the iceberg, not the water
Hemingway’s iceberg theory is the foundation of all compressed fiction: the writer knows far more than appears on the page, and that invisible knowledge gives the visible text its weight.
Know your character’s entire history, then put almost none of it on the page. A woman orders two coffees out of habit, then stares at the second cup. You do not need to tell the reader someone has died. The second cup says it.
Use concrete details, not abstract language
Flash fiction lives in the specific. Not “she was sad” but “she folded his shirts into the suitcase and left the top one unfolded because it still smelled like him.”
This is the principle behind show don’t tell — in flash, not a suggestion. The whole game. Search your drafts for words like “beautiful,” “lonely,” “painful.” Replace each with a physical detail. The story always improves.
Read it aloud
Flash fiction has a rhythm. The only way to hear it is to read aloud. Where you stumble, the sentence is wrong. Where you run out of breath, the sentence is too long. Your ear knows things your eye misses.
Where to start
Read Amy Hempel, Raymond Carver, and Lydia Davis. Then write something under 500 words. Write the last line first. Then write everything that leads to it. Cut the first paragraph. Read it aloud. Cut anything that explains what the reader can already feel. Then write another one.
