Generating 4:5 images with kublaro
When the selected Kublaro model exposes 4:5, choose it before generation so the composition is requested for that frame. Supported ratios, delivered pixel dimensions, and resizing behavior can vary by model. Verify the exported width and height; an exact source ratio does not prevent a downstream platform, template, or print lab from cropping it.
- Create your kublaro account and open the create studio.
- Choose a model that currently exposes 4:5, then set that ratio in its generation settings.
- Write your prompt with the portrait composition in mind.
- Generate, refine, export, and verify the delivered pixel dimensions before publishing.
