Prompts for Stable Diffusion: Parameter Guide 2026
Stable Diffusion gives you full control over image generation, but that Control comes with complexity. This guide explains all the parameters and techniques so that Get professional results consistently.
Prompt Structure for Stable Diffusion
Unlike Midjourney, SD allows a positive and a negative prompt with weights for each element:
Positive prompt:
(masterpiece:1.4), (best quality:1.2), photorealistic portrait of a woman, soft lighting, bokeh background
Negative prompt:
(worst quality:1.4), (low quality:1.2), blurry, deformed hands, extra fingers, watermark, text, logo
(masterpiece:1.4), (best quality:1.2), photorealistic portrait of a woman, soft lighting, bokeh background
Negative prompt:
(worst quality:1.4), (low quality:1.2), blurry, deformed hands, extra fingers, watermark, text, logo
Key Parameters of Stable Diffusion
| Parameter | Range | When to use it |
|---|---|---|
| CFG Scale | 1-30 (ideal: 7-11) | Older = more faithful to the prompt, less creative |
| steps | 20-150 (ideal: 30-50) | More steps = more detail, more time |
| Seed | -1 or fixed number | Fixed seed reproduces exactly the same result |
| Size | 512x512 to 1024x1024 | HD requires SDXL models |
Negative Prompts: The Key to Professional Results
The negative prompt is what differentiates amateur results from professional ones. Here you have the Universal negative prompt that enhances any image:
(worst quality, low quality:1.4), (bad anatomy:1.3), (deformed, distorted:1.3),
extra limbs, extra fingers, missing fingers, blurry, pixelated, watermark, signature, text, logo,
jpeg artifacts, compression artifacts, doll, duplicate, cropped
