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 Flux 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.
