Dimensions and Aspect Ratio
Available dimension and aspect ratio options in Qolaba's Image Generation workspace
Dimensions control the shape and pixel proportions of your generated image. Selecting the right dimensions before generating ensures your output fits its intended platform or format without cropping, stretching, or requiring post-generation resizing.
How Dimensions Work
Dimensions define the aspect ratio and pixel size of the generated output. Qolaba provides a range of preset dimensions — including standard orientations and platform-specific sizes — so you can match your output to its intended destination without manual calculation.
Dimensions do not affect credit cost. You can change them freely without impacting your generation budget.

Choosing the Right Dimensions
Match dimensions to your delivery format before generating — resizing after generation degrades quality and introduces cropping or letterboxing. Select the dimension preset that matches where the image will be used.
For multi-platform content: Generate separate versions at the required dimensions for each platform. Because dimensions do not affect credit cost, producing a square and a portrait version of the same image costs the same as generating one — only the generation count changes.
For reference-guided generation: Match your output dimensions to the natural aspect ratio of your reference image. A portrait reference used with a landscape output dimension will be cropped or distorted in the generated output.
Dimensions and Reference Images
When uploading reference images, the aspect ratio of your reference influences how the model frames the generated output. Mismatched dimensions between your reference and output setting can result in:
Cropping — parts of the reference are cut off and excluded from the generation
Distortion — the reference is stretched to fill the output frame unnaturally
Recomposition — the model adds padding or repositions elements to fill the frame
To avoid this, always check the aspect ratio of your reference images before selecting output dimensions. See Reference Image Uploads → for more guidance on using references effectively.
