Nano Banana Prompt Guide: Structure, Examples, and Pitfalls to Avoid

Want Nano Banana Pro to deliver visuals that look launch-ready instead of drafty? The trick is to structure your prompt, state text requirements up front, and add a tight negative list. This guide gives you a universal formula, Pro-specific tips, and 10 English prompts you can paste and run.

The Golden Prompt Structure

A high-quality prompt typically includes the following elements:

• Goal: poster / product page / social post / infographic; the purpose decides density and whitespace.
• Subject + action: who/what, doing what, mood/pose.
• Framing: close-up / mid-shot / wide, top-down / low-angle / 45°, depth of field, whitespace area.
• Light + material: soft/hard light, neon, high contrast, film grain, metallic/ceramic/wood textures.
• Style + palette: cyberpunk, minimal tech, retro-future, brand colors.
• Text + layout: what title/subtitle/button copy must appear, mono/bilingual.
• Resolution + ratio: 1K/2K/4K, 16:9, 1:1, 9:16, etc.
• Negative keywords: watermark, logos, dirty textures, deformed hands, overexposure, blurry text.

Fast template (fill in the blanks):

A visual for 【goal/use case】. Main subject: 【who/what】 is 【action】. Framing: 【close-up/mid/wide】, lighting: 【type】, style: 【style + palette】. Reserve 【area】 for text; title: “【title】”, subtitle: “【subtitle】”. 4K, sharp, clear structure, readable text. Negative: watermark, blur, deformed hands, misspelled text, stretching.

Nano Banana Pro Prompting Tips

Here are practical tips summarized from experience:

• Lock structure first, then layer style: start with goal + subject + framing + light; add style/material after the layout is stable.
• Text readability: declare the actual copy in the positive prompt; add “text is clear and readable, tidy typography.” Avoid “no text” in negatives or it will remove text entirely.
• Iterate in small steps: change only 1–2 dimensions per pass (e.g., just palette or just lighting) for clean comparisons.
• Character/product consistency: repeat the same colors/outfit/props; keep the same camera language across a series.
• Dense information: specify “grid/card layout” or “symmetry” plus “high-contrast labels” to keep elements aligned.

Quick Start Steps

1. Open Nano Banana Pro and select "Text to Image" mode.
2. Draft the core line with the golden structure.
3. Pick aspect ratio and resolution (16:9 for marketing, 4:5 or 1:1 for social, 9:16 for short video covers).
4. Put the exact copy in the positive prompt; do not suppress text in negatives.
5. Change one variable at a time (lighting/palette/layout) and compare.
6. Keep a reusable negative list to reduce defects.

Pitfalls to Avoid

• Missing or warped text: state "text is clear and readable, tidy typography," and avoid "no text."
• Crowded layout: define the use case, info density, and where whitespace goes.
• Inconsistent characters: repeat outfit colors, hairstyle, props; keep the same scene/camera language across shots.
• Low-end finish: specify materials like "soft volumetric light," "glassmorphism," "brushed metal" or "ceramic."
• Off-brand colors: pin "brand primary + secondary," then ask for "harmonized palette with clear contrast."
