How long should a Stable Diffusion text prompt be?

Three-step prompt formula
- Define the subject, setting, and mood in one sentence so Stable Diffusion knows the core idea (e.g. “Astronaut exploring a neon jungle at night”).
- Add style direction—reference art movements, mediums, lighting, or camera gear to influence the aesthetic.
- Finish with quality boosters such as “ultra detailed, sharp focus, 4K render” and include a short negative prompt to remove blur, watermarks, or anatomy issues.

Text-to-image FAQ
What is the best way to reuse prompts?
Save your favorite prompts along with the seed, model, and aspect ratio. Re-running the same seed in the playground produces consistent layouts you can tweak further.
Do I always need a negative prompt?
Negative prompts are optional but highly effective. Adding terms like “blur, watermark, distorted hands” keeps images clean and reduces retouching time.
