With the right 20 prompts, you can turn simple ideas into stunning lock-screen and home-screen art, minimal gradients, dreamy landscapes, neon cityscapes, anime-style scenes, or abstract patterns perfectly framed for your phone’s display.
These prompts are crafted to control color, lighting, aspect ratio, and composition so your wallpapers look clean, crisp, and distraction-free while still feeling unique and aesthetic.
Whether you are a beginner exploring AI art or a creator planning a full wallpaper pack, Nano Banana Pro helps you produce consistent, high-resolution designs ready to save, share, or even monetize.
Simple steps to create wallpaper images
- Open the Gemini app or web, go to Tools and select “Create images,” then choose the Nano Banana Pro / Gemini 3 Pro Image model.
- Set the aspect ratio to match your phone (usually 9:16 or 20:9 vertical) if the interface allows, or mention it directly in your prompt.
- Type your wallpaper prompt, clearly describing subject, colors, style, and mood (for example: “vertical 9:16 pastel gradient sky with tiny stars, minimal, no text”).
- Click Generate and wait for the image, then download the best version and set it as your lock-screen or home-screen wallpaper from your phone’s gallery.
Tips and tricks for beautiful wallpapers
- Always specify “vertical smartphone wallpaper, 4K resolution, 9:16 aspect ratio, no text, no watermark in center” so the layout fits your screen cleanly.
- Keep compositions simple: focus on one main subject or pattern, soft gradients, and space at the top and center where the clock and icons appear.
- Lock in a color theme (pastel, neon, dark mode-friendly) and reuse it across multiple prompts to build a matching wallpaper series.
- If details look messy, shorten the prompt and reduce elements; if it feels too plain, slowly add one element at a time (fog, stars, bokeh, mountains, waves).
