What size are YouTube thumbnails?

YouTube recommends 1280x720 pixels (16:9 aspect ratio). Our generator defaults to 16:9 to match this standard. The generated images are high-resolution and ready to upload directly to YouTube.

Can I add bold text to my thumbnails?

Yes. Include the text you want in your prompt — for example: 'YouTube thumbnail with bold text SHIP FASTER on dark gradient'. Models like Recraft V4 and Nano Banana Pro handle text rendering well.

How do I create consistent thumbnails for a series?

Use prompt templates in the CLI to define a consistent style. Save a template with your brand colors, layout style, and text placement, then generate variations for each episode. The API also supports this for automated workflows.

Which model makes the best YouTube thumbnails?

Nano Banana Pro (4 credits) delivers the best results for thumbnails with text and faces. For simpler, graphic-style thumbnails, Recraft V4 (1 credit) offers great typography at a lower credit cost.
