What is a custom ratio AI image generator?
A custom ratio AI image generator creates images in different aspect ratios to fit specific layouts. You describe the scene and mention the intended placement (wide banner, tall poster, square tile), choose the available ratio settings, then generate and review the result. The composition adjusts to the frame so banners keep subjects centered horizontally and posters frame content vertically.
Custom Ratio AI Image Generator for Any Layout
Tall poster for an event
Input
A tall poster of a retro sci-fi film night, neon grid background and a lone astronaut

A vertical composition with the poster subject centered and breathing room around it.
Square profile tile
Input
A square emblem of a coffee cup with steam curling into a heart shape
Expected output
A compact square image that works as an avatar or profile tile.
Generate images suited to specific layouts like banners, posters, or wallpapers from text descriptions
Aims at your placement
Start with the shape you need in mind so banners, posters, and wallpapers keep their composition when placed.
Less time cropping
Describe the intended frame up front and choose the available settings, so you spend less time cutting or repositioning after generation.
One loop for many formats
The same prompt, settings, and review workflow works whether you need a wide header or a square tile.

Working with image proportions
Describe the placement you have in mind, then review the result at full size before you use it.
Input Constraints
- Describe the subject and setting clearly so the scene reads well in a wide or tall frame.
- Review the result at full size before publishing or printing.
- Use only inputs and source material you have permission to use.
Practical Tips
- Mention the intended placement in your prompt, such as a header, poster, or profile tile.
- Keep the main subject away from the edges in case the image gets cropped.
- Adjust the wording and the available settings, then generate again when the composition is off.
Privacy
- Do not upload personal or sensitive material unless you have permission to use it.
Usage Rights
- Confirm that you have the rights needed for the inputs and intended use of the result.
Prompt recipes

Ultra-wide desktop wallpaper
A vast desert landscape with sand dunes at golden hour, wide panoramic view, clear sky with gradient from orange to purple, horizontal composition for ultra-wide monitor
Specifies panoramic framing and horizontal emphasis for wide desktop displays, with clear subject distribution across the frame.
Vertical mobile wallpaper
A tall waterfall cascading down a misty cliff, lush green forest at the bottom, vertical composition, space at top for mobile status bar
Describes vertical subject flow and leaves functional space at top for mobile UI, ensuring the focal point remains visible.
Social media cover banner
A wide banner of a cozy coffee shop interior, warm lighting, centered counter with pastries, horizontal composition with important elements in the center third
Keeps key elements in the safe center zone for banners that may be cropped differently across platforms.
Square Instagram post
A balanced overhead shot of a workspace with laptop, coffee cup, and notebook, square composition, centered layout, even margins
Centers subject in square frame with breathing room, optimized for social feeds where edges may be obscured by UI.
Tall event poster
A vertical concert poster with band silhouettes at the bottom third, colorful abstract light rays filling the upper two-thirds, title space at top
Distributes visual weight vertically with space for text, following poster hierarchy conventions for readability.

Limitations to know before generating
- The available ratio settings may not match every platform's exact dimensions; plan for minor cropping in final layout.
- Extreme ratios (very wide or very tall) can produce stretched or awkward compositions; review carefully before use.
- Text placement zones must be described in the prompt; the tool will not automatically reserve specific areas.
- Generated images may need editing to add text, logos, or other overlay elements for final publication.
- Not all scenes work well in all ratios—wide landscapes suit banners, tall subjects suit posters; choose prompts that fit the frame.
