Frequently Asked Questions About AI Image Aspect Ratios
How does the AI Aspect Ratio Calculator work?
The AI Aspect Ratio Calculator automatically computes the optimal dimensions for different AI image generation models (Midjourney, DALL-E 3, Stable Diffusion, and Flux 1.1 Pro). Enter your desired width and height, and it generates the correct prompt format with appropriate aspect ratios for each model while respecting their specific limitations and requirements.
How do I use aspect ratios in Midjourney?
In Midjourney v5, use the '--ar' parameter followed by width:height (e.g., '--ar 16:9' for widescreen). Midjourney v6 uses '--aspect' instead. The calculator automatically formats these commands for you. Midjourney v5 supports ratios up to 2:1, while v6 extends to 3:1 for more extreme compositions.
What aspect ratios does DALL-E 3 support?
DALL-E 3 supports specific preset aspect ratios: square (1:1), landscape (16:9), and portrait (9:16). The maximum resolution is 1792x1024 pixels. Our calculator automatically adjusts your dimensions to the closest supported DALL-E 3 format while maintaining the best possible quality.
How do I set custom dimensions in Stable Diffusion?
Stable Diffusion uses '--w' for width and '--h' for height parameters (e.g., '--w 1024 --h 768'). The calculator generates these parameters automatically. While Stable Diffusion supports custom dimensions, it works best with sizes up to 1024x1024 pixels for optimal quality.
What's the difference between aspect ratio and resolution?
Aspect ratio is the proportional relationship between width and height (e.g., 16:9, 4:3), while resolution is the actual pixel dimensions (e.g., 1920x1080). Our calculator helps you maintain the desired aspect ratio while optimizing the resolution for each AI model's capabilities.
Which aspect ratios work best for social media?
Different platforms have optimal ratios: Instagram prefers 1:1 (square) or 4:5 (portrait), Twitter works best with 16:9, and Facebook accommodates 1.91:1. Our calculator can help you format these ratios correctly for AI image generation across different models.
About AI Image Aspect Ratio Calculator
Our AI Image Aspect Ratio Calculator is designed to help you generate perfect dimensions for AI image generation models including Midjourney (v5 and v6), DALL-E 3, Stable Diffusion, and Flux 1.1 Pro. Whether you're creating images for social media, marketing materials, or artistic projects, this tool ensures your prompts use the optimal aspect ratios and resolutions for each AI model.
The calculator supports all major AI image generation platforms and automatically formats the correct prompt syntax for each service. It handles Midjourney's --ar and --aspect commands, DALL-E 3's size requirements, Stable Diffusion's width and height parameters, and Flux's dimension specifications. This makes it easier to generate consistent, high-quality images across different AI platforms without memorizing their specific formatting requirements.
