Bug: Image Generation Ignores Custom Size — Always Outputs 1536×1024

Support Bug Reports
1

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When generating images in Cursor (via Agent or Composer), explicitly requesting a specific size such as 750x1500px completely ignored. Regardless of how the prompt is phrased, the generated image is always 1536 × 1024 pixels.
This makes it impossible to generate UI assets, icons, thumbnails, or any image that requires precise dimensions.

Impact:
This blocks all workflows that depend on exact image sizes. A quick fix or support for explicit width x heightparameters would be greatly appreciated.

Steps to Reproduce

  1. Open Cursor Agent / Composer
  2. Prompt: Generate a 200x200px solid blue square
  3. Download or inspect the generated image

Expected Behavior

The image should match the requested dimensions (e.g., 750x1500 px).

Actual Behavior:​
The image is always generated at 1536 × 1024 px, ignoring the requested size entirely.

Hey, thanks for the report. This isn’t exactly a bug, it’s a current limitation. The image generation tool doesn’t accept size or dimension params in the prompt right now. The output resolution is set by the model provider’s default, which is currently 1536×1024, so requests like “200x200px” or “750x1500” get ignored no matter how you phrase them.

We’re already tracking support for custom sizes and aspect ratio as a request, but there’s no timeline yet. If there’s an update, I’ll follow up.
