Short answer: Aspect ratio controls the shape of the image. Resolution controls output size and detail.
Steps
Choose an aspect ratio that matches the destination, such as square, portrait, or landscape.
Choose a resolution supported by the selected model.
Use portrait ratios for phone-first visuals and landscape ratios for wide scenes.
Generate and review the composition before downloading or sharing.
Notes
Higher resolution can create larger, more detailed outputs, but support varies by model.
Some models support exact width-by-height sizes behind the app’s resolution controls.
