Match size and subtlety to the use
Pick the aspect ratio for where the background will go: Landscape (16:9) for slides, video and desktop; Portrait for phone screens and stories; Square for social. For a background that sits behind text or content, prompt for something subtle and low-contrast so your foreground stays readable.
Words like "subtle", "soft gradient", "minimal texture", "muted" and "atmospheric" produce backgrounds that support content rather than fight it. For a hero image, you can go bolder.
Background ideas
- Abstract gradients and flowing shapes.
- Subtle geometric or dotted patterns.
- Atmospheric landscapes (mountains, sky, ocean).
