Stable Diffusion Aspect Ratio (--ar) Guide

Aspect ratio determines the width-to-height dimensions of your Stable Diffusion output, which directly affects composition and how the model fills the frame. This guide covers standard ratios, how resolution interacts with aspect ratio, and which settings work best for portraits, landscapes, and square formats.

Pro Tips

  • 1Start with the default Aspect Ratio (--ar) value and make small adjustments to understand how it affects your specific prompt style.
  • 2Different styles respond differently to Aspect Ratio (--ar) changes — what works for photorealistic may not work for anime or abstract.
  • 3Keep notes on which Aspect Ratio (--ar) values work best for your favorite prompt structures — this builds your personal Stable Diffusion knowledge base.
  • 4When sharing prompts, always include your Aspect Ratio (--ar) setting — it can dramatically change results even with identical prompt text.
  • 5For batch generation, lock your Aspect Ratio (--ar) value to maintain consistency across an entire set of related images.

Common Mistakes

Using extreme Aspect Ratio (--ar) values without understanding the trade-offs — moderate values usually produce the most balanced results.
Assuming the same Aspect Ratio (--ar) value works for all styles — always test with your specific prompt before committing to a batch.
Changing Aspect Ratio (--ar) and other settings simultaneously — adjust one parameter at a time to understand each one's effect.
