How to Write Flash Fiction in Under 500 Words

What is flash fiction?

Flash fiction is a very short story, usually under 500 words, that delivers a complete narrative with a clear beginning, middle and end. It’s a great way to practice brevity and precision. It can be so short that it fits in a tweet!

Examples:

  • Stories focusing on a single moment or event
  • Characters facing a sudden dilemma or revelation
  • Using minimal description but strong emotions

Tips:

  • Keep the plot simple and focused
  • Use strong, concise language
  • Show rather than tell to maximise impact

How do I create a compelling character quickly?

In flash fiction, there’s little room for lengthy backstories. Use brief but telling details to hint at character personality and motivation. Character introductions should be just a few well-chosen words.

“Mira adjusted her cracked glasses, scanning the horizon like she’d done every morning since the sky fell.”

In one sentence, we get:

  • A visual detail (cracked glasses)
  • A hint of habit or resilience (every morning)
  • A sense of worldbuilding or backstory (since the sky fell)

Examples:

  • A unique trait or action that reveals character
  • Dialogue that hints at deeper feelings
  • A vivid physical description with emotional weight

Tips:

  • Focus on one key trait or conflict
  • Avoid multiple characters to keep clarity
  • Let character actions drive the story

How can I create tension and conflict in so few words?

Tension is essential even in brief stories. Start the problem early and give a hint of what the character might lose, so the reader gets interested fast.

Examples:

  • A sudden twist or surprise
  • Internal conflict revealed in thought or dialogue
  • A dilemma that demands an immediate choice

Tips:

  • Begin as close to the action as possible
  • Use strong verbs and active voice
  • Avoid unnecessary exposition

How do I decide what to leave out?

Editing is crucial in flash fiction. Trim everything that does not serve the core story or emotional impact. (Sometimes you really do need to cut the first draft completely in half!)

Examples:

  • Removing excessive description or backstory
  • Avoiding side plots or subplots
  • Cutting filler words and clichés

Tips:

  • Read aloud to spot awkward or unnecessary parts
  • Get feedback focused on clarity and pace
  • Remember less is often more

How do I end flash fiction effectively?

A strong ending can leave a lasting impression. Aim for a punchy, surprising or poignant conclusion. (Try ending a story with a single word that says everything.)

Examples:

  • A twist that redefines the story
  • An emotional revelation or decision
  • An open ending that invites reflection

Tips:

  • Avoid over-explaining the ending
  • Let the reader fill in some gaps
  • Keep the tone consistent to the story

Examples of flash fiction writing

The New Door

Ella stood on the cracked pavement, keys heavy in her palm. The house was smaller than she imagined, with peeling paint and a crooked mailbox leaning as if it had secrets to tell. But it was hers.

Inside, the smell of old wood and forgotten stories filled the air. She ran her fingers along the dusty banister, imagining laughter echoing through the rooms, her laughter someday. The walls whispered promises.

In the kitchen, she found a faded note taped inside a cupboard: “Home isn’t just a place; it’s the people you bring in.” A chill ran down her spine, but she smiled. Maybe this house already knew her story.

That night, as she lay on the creaky floorboards with the moonlight draped over her, Ella felt the house breathing with her. It was alive and waiting. She was no longer just buying a building. She was claiming a future.

The New Door is 192 words long.


Inheritance

When the doctors said he wouldn’t live past thirty, Jonah smiled. He had plans. He’d write, travel, love.

At twenty-nine, lying in a sterile room, he heard his mother’s voice on the phone. “He won’t need the house. Sell it. Take the money.”

She never visited.

After he died, the house sold for a fortune. The new owner tore down every wall Jonah had painted, every mark he’d made.

No one remembered him.

Months later, the buyer found a hidden sketchbook buried in the attic — pages filled with dreams, hopes, and warnings: “Don’t forget me.”

The buyer tossed it into the fire.

Jonah’s story died twice — once with him, once with their indifference.

Inheritance is 150 words long.

The Collector

Mr. Graves was proud of his collection. Rare antiques, stolen from every corner of the world. Each piece whispered of lives ruined, families broken.

One rainy evening, a knock came at his door. No one was there, just a small box with a note: “Your turn.”

Inside, he found a cracked mirror and a withered leaf.

That night, he woke unable to move, trapped inside his own reflection. The mirror showed every face he’d wronged. Their pain, their fury.

Days turned to weeks. Mr. Graves watched helplessly as his body withered, his legacy shattered.

When the neighbours found him, the mirror was shattered, but his eyes remained frozen in terror. The collector finally collected.

The Collector is 140 words long.
