Nano Banana Prompt Examples by Use Case

📱 Social Media Post Prompt Example

Recommended aspect ratio: 1:1 or 4:5

A photo-style social media post image of an iced coffee and a notebook on a cafe table generated by Nano Banana 1:1

Prompt:

Create an image based on the following details. 1.Subject ... An iced coffee and a small notebook placed on a cafe table 2.Purpose ... Image for a social media post 3.Style ... Photo style 4.Mood ... Bright, relaxing weekend atmosphere 5.Composition/Background ... Simple and stylish composition with a slightly blurred background, natural light 6.Aspect Ratio ... 1:1 7.Elements to Include ... Iced coffee, small notebook, wooden table, natural light 8.Elements to Avoid ... Do not include any people or text

Tip:
For social media posts, we recommend keeping the subject simple so it is easily understood on mobile screens. Leaving some negative space makes it easier to pair with posts or text overlay.

📝 Blog Featured Image Prompt Example

Recommended aspect ratio: 16:9 or 3:2

A blog featured illustration image generated by Nano Banana 16:9

Prompt:

Create an image based on the following details. 1.Subject ... A laptop showing an abstract UI of an AI image generation tool 2.Purpose ... Image for a blog post hero/eyecatch 3.Style ... Minimal flat illustration style 4.Mood ... Bright, tech-oriented, and friendly atmosphere 5.Composition/Background ... Laptop in the center, with clean negative space on the sides for article titles, white background 6.Aspect Ratio ... 16:9 7.Elements to Include ... Abstract UI screen, small image thumbnails, text input field, subtle light effects, white space 8.Elements to Avoid ... Do not include real logos or readable text

Tip:
Since blog featured images often have titles overlayed later, it is helpful to specify "plenty of negative space" or "a composition that makes it easy to add text later" in your prompt.

📣 Ad Banner Prompt Example

Recommended aspect ratio: 16:9 or 4:5

An ad banner background image of a living room generated by Nano Banana 16:9

Prompt:

Create an image based on the following details. 1.Subject ... A simple sofa and a low table in a bright living room 2.Purpose ... Background image for a new life campaign advertising banner 3.Style ... Photo style 4.Mood ... Clean, fresh, friendly, and spring-like atmosphere 5.Composition/Background ...

Sofa, low table, green houseplant, natural light, clean negative space 8.Elements to Avoid ... Do not include any people, text, or logos

Tip:
Because ad banners often require overlaying product images, copy, and CTA buttons, generating only the background image is highly recommended.

🛍️ Product Image Prompt Example

A skincare bottle product image generated by Nano Banana 1:1

Prompt:

Create an image based on the following details. 1.Subject ... A product shot of a transparent skincare bottle placed in the center 2.Purpose ...

Skincare bottle, soft natural light, subtle water droplets, small green leaves 8.Elements to Avoid ... Do not include any text, logos, people, or hands

Tip:
AI cannot always replicate specific real-world products accurately. When dealing with physical products, it is best to use AI-generated images for background concepts or visual direction rather than the final product shot.

Specifying the expression, personality, colors, and purpose helps keep character designs consistent. To create multiple poses/expressions, you can ask the AI to "keep the same character but change the facial expression."

FAQ

Can I write Nano Banana prompts in Japanese?
  • Yes, Japanese is supported. However, using English is recommended to achieve more consistent style details and subtle nuances.

Are there any tips for editing photos with Nano Banana?
  • When editing photos, it is crucial to clearly separate "what to change" from "what to keep."
  • For example, if you only want to change the background, specifying "Keep the main subject as is and change only the background to a bright, white studio background" will prevent unwanted changes to the person or product.

What should I include in a background replacement prompt?
  • For background replacement, we recommend describing three key points: "what to keep," "what to change the background to," and "what not to alter."
  • It is helpful to include a sentence explicitly instructing the AI to preserve the product's shape, color, texture, and label position.

What aspect ratio is best for creating social media images with Nano Banana?
  • It depends on your target platform. We recommend using 1:1 or 4:5 for Instagram posts, 9:16 for Stories, 16:9 for X posts, and 16:9 for blog featured images.
