Nano Banana Tutorial: Aligning Multiple Product Shots into a Grid Layout

Creating a professional product grid for an online store requires more than just placing images side by side. The visual harmony of the final layout depends heavily on maintaining consistent lighting, scale, and perspective across every tile. This tutorial guides you through using Nano Banana to align multiple product shots into a unified composition. Whether you are showcasing a collection of ceramic vases or a set of kitchenware, this process ensures your customers see a polished, brand-aligned display.

Nano Banana is an AI image generation and editing tool designed to handle complex visual tasks. It supports both text-to-image and image-to-image workflows, allowing you to start from scratch or refine existing assets. By leveraging these capabilities, you can generate variations that fit perfectly within a grid structure without manual Photoshop manipulation. Remember, Nano Banana refers to the AI tool itself, not a specific cosmetic brand or physical product. All examples discussed here involve generic, unbranded items to demonstrate the technique effectively.

Prerequisites for Grid Composition

Before beginning the alignment process, ensure you have the necessary inputs ready. Successful grid creation relies on having clear, high-quality source images of your products. These should be individual shots where the product is isolated or clearly defined against a neutral background. While Nano Banana can work with various inputs, consistency in the initial photography style helps the AI maintain uniformity during the compositing phase.

You will also need access to the Nano Banana interface at /nanobanana2. This platform hosts the tools required for generating and editing images. Familiarize yourself with the prompt library available on the site, which offers example prompts that users can copy or adapt. These prompts describe desired outcomes but do not guarantee identity, label, object, or typography preservation. Therefore, treat any specific text or logo instructions as flexible guidelines rather than absolute rules.

It is important to select the correct model variant for this task. Google documents Nano Banana 2 as Gemini 3.1 Flash Image, while Nano Banana Pro uses Gemini 3 Pro Image. For this tutorial, we recommend using the standard Nano Banana 2 or Pro version because they support multi-turn sequential editing and handling multiple reference inputs better than other options. Try Nano Banana to access the full suite of features needed for this workflow.

Step-by-Step Alignment Process

The core of creating a grid layout involves guiding the AI to understand spatial relationships between multiple objects. Follow these numbered steps to compose your grid effectively:

1. Prepare Your Inputs: Gather your individual product images. Ensure they are all oriented similarly (e.g., all facing forward) and have similar lighting conditions if possible. If the lighting varies significantly, the AI may struggle to blend them seamlessly.
2. Initiate Image-to-Image Workflow: Upload your first product image to the Nano Banana generator. Select the image-to-image mode to allow the AI to retain the subject's shape while adjusting its context.
3. Draft the Prompt: Enter a detailed prompt describing the goal. For example, "Create a grid layout containing four ceramic vases with consistent soft studio lighting and white background." Use the prompt library for inspiration, but customize it to specify the number of tiles and the arrangement.
4. Iterate with Sequential Editing: If the first result does not align perfectly, use the multi-turn editing feature. You can upload the generated grid as a new input and ask the AI to "adjust the spacing between the tiles" or "align the bottom edges of all products." This step-by-step refinement is crucial for precision.
5. Review and Refine Scale: Check that all products appear to be the same size relative to one another. If one item looks disproportionately large, re-prompt specifically about scaling, such as "ensure all ceramic items are identical in height and width."
6. Finalize the Output: Once the grid looks cohesive, download the final image. Verify that no unintended artifacts or misalignments exist before using it for your e-commerce listing.

Judging Results and Troubleshooting Common Issues

Evaluating the success of your grid composition involves checking for visual continuity. The most critical factor is whether the lighting feels natural across all tiles. Shadows should fall in the same direction, and highlights should match the intensity of the light source. Additionally, check the scale; products should not appear to shrink or grow as you move across the grid.

If the results look disjointed, consider the following fixes. First, ensure you are not using Nano Banana 2 Lite for this specific task. Google describes Nano Banana 2 Lite as focused on speed and cost, noting that it is not optimized for multiple reference inputs or multi-turn sequential editing. Using Lite for complex grid compositions may lead to inconsistent outputs or failure to maintain alignment across multiple images. Always choose the standard Nano Banana 2 or Pro models for this level of detail.

Another common issue is the loss of product identity. Since prompt instructions do not guarantee object preservation, the AI might alter the shape of a vase slightly. To mitigate this, provide very specific descriptions of the product's geometry in your prompt. For instance, instead of saying "a vase," say "a tall cylindrical ceramic vase with a flared rim." This specificity helps the AI maintain the intended form while arranging the grid.

Remember that these prompt examples are illustrative. They serve as a starting point for your own creativity but do not guarantee a specific outcome. The quality of the final grid depends on the clarity of your instructions and the iterative nature of the editing process. By following these steps and understanding the limitations of each model variant, you can create stunning, professional product grids that enhance your online store's presentation.
