What size blog thumbnails can I generate?

Our blog thumbnail generator defaults to 16:9 aspect ratio — the standard for blog headers and featured images. You can also generate 1:1, 4:3, and other aspect ratios depending on your blog layout and CMS requirements.

Can I generate thumbnails that match my brand style?

Yes. Describe your brand aesthetic in the prompt — colors, style, mood. For example: 'Blog thumbnail with dark gradient, emerald accent colors, minimalist tech aesthetic'. The AI will generate images consistent with your described brand guidelines.

How do developers use this for their blogs?

Many developers use our CLI tool to batch-generate blog thumbnails from the terminal: pixelmuse generate 'blog thumbnail for Next.js tutorial' --aspect-ratio 16:9. You can also use the REST API to automate thumbnail generation in your CI/CD pipeline or CMS.

What models work best for blog thumbnails?

Nano Banana 2 (1 credit) is great for fast, clean thumbnails. Recraft V4 (1 credit) excels at typography-heavy designs. For photorealistic blog headers, try Imagen 3 or Nano Banana Pro.
