Any tips for getting a good result from YouTube Thumbnail Generator?

Keep the text short — three or four large words.

Can I include my brand colours?

Yes. Describe them in the prompt — "deep teal background with warm cream text area" — and the tool matches the palette rather than guessing.

Where does the text come from?

Describe the wording you want in the prompt. Keep it short: a name, a title, or a three-word headline renders cleanly, while full paragraphs do not.

What sizes do I get?

Outputs follow common platform ratios — 16:9 for YouTube thumbnails, 1:1 for Instagram, 4:5 for feed posts — so no cropping before upload.
