How to INSTANTLY Fix Gemini 'Nano Banana' Aspect Ratio Problems When Creating Images

👉 In this video, I will show you how to fix the frustrating aspect ratio issues in Gemini Nano Banana when it keeps generating square 1:1 images instead of your desired 16:9 or other formats during image creation and editing. I'll reveal the simple workaround that finally gives you full control over your image dimensions without compromising quality, solving the most common Nano Banana aspect ratio problem that's been driving creators crazy.

For creating blank picture app:
Create a minimalist web-based tool that generates transparent PNG files with user-specified aspect ratios, featuring a clean interface with input fields for width and height dimensions (or common preset ratios like 16:9, 4:3, 1:1), a preview area showing the transparent canvas dimensions, and a prominent download button that instantly generates and downloads a fully transparent PNG file matching the specified aspect ratio. The tool should include intuitive controls with real-time dimension feedback, support for both custom pixel dimensions and standard aspect ratio presets, validate inputs to prevent errors, display a visual representation of the canvas size without actual content, and provide immediate file download functionality with appropriately named files (e.g., "transparent_1920x1080.png") while maintaining a responsive, accessible design that works across all modern browsers and devices.

For creating picture:
Use the picture as the reference for final aspect ratio.

For editing picture:
Use the second picture as the reference for final aspect ratio and fill the area that wasn't shown in the original picture.
