How to write flash fiction

Flash fiction is not a short story that ran out of room. It is a form with its own logic, and the logic is compression: everything that can be implied must be implied, and what remains has to do several jobs at once.

Common lengths: under 1,000 words is flash; under 300 is often called micro; 100 words exactly (drabble) and 50 words are their own competitions. Many journals set 500 or 750 as the cap.

What a very short story can carry

One character, or two. One scene, or one moment across a short span. One change.

That last one is the requirement. Something must be different at the end — a realisation, a decision, a revealed fact that reframes what came before. A vivid scene in which nothing shifts is a fragment, and it is the most common rejection.

What it cannot carry: a subplot, a large cast, a full arc of transformation, extensive backstory, world-building for its own sake.

Where to start

Start as late as you possibly can. In flash this is not advice, it is the form. If the story is about a woman deciding to leave, begin at the moment of the decision, not at breakfast.

Better still, begin after the inciting event, so the reader arrives mid-consequence and assembles the cause themselves. That assembly is a large part of the pleasure.

The first line has to establish situation and voice simultaneously. It is the hardest sentence in the piece and is usually written last.

Implication does the work

You cannot explain. You can only place a detail and let it carry the weight.

She set two places, then put one back. Eight words. A relationship, a loss, a length of time, a habit not yet unlearned. Explaining any of it would make it worse.

Choose details that are specific and load-bearing. In a 500-word story a mentioned object has to earn its place — if it is only scenery, it is costing you a sentence that could do something.

Concrete nouns and strong verbs. Adjectives and adverbs are where flash goes soft; they take space and usually restate what a better verb would have carried.

Endings

The ending is where flash fiction most often fails, in two opposite directions.

The over-explained ending spells out what the story meant. Delete the last paragraph — most flash improves, and the real ending is usually one or two sentences earlier than you thought.

The twist for its own sake. A reveal that recontextualises is powerful; a reveal that only surprises is a trick, and readers of the form have seen the common ones many times — the narrator was the dog, it was all a dream, the child was dead the whole time.

Aim for an ending that is surprising and, on rereading, inevitable.

Revising

Write it long, then cut hard. A first draft at 900 words often becomes a much better 500-word story.

Cut in this order: adverbs, filler ("just", "really", "somewhat", "began to", "seemed to"), dialogue tags beyond "said", any sentence that explains a previous sentence, backstory, and finally the first paragraph — which in flash is very often throat-clearing.

Read it aloud. In a form this short, rhythm is structural.

Common mistakes

A scene with no change. Explaining the ending. Too many characters — give two people names and a third becomes crowding. Backstory. A twist that does not survive a reread. Adverbs. Titles that give away the ending, though in flash the title can and often should do real work as a first line of context.

Practical tips

• Set a hard word limit before you start and write to it.
• Give the story one image it can be remembered by.
• Cut the first sentence and see whether the story is better. Often it is.
• Read widely in the form — journals publish flash free online, and the form is learned mostly by reading it.
• Check each journal's limit precisely: 500 means 500, and going over is an automatic decline at most of them.
