AI image generators differ in size specification, requiring post-generation adjustment

When generating images with AI tools like ChatGPT, Midjourney, Stable Diffusion, and Gemini, the specified pixel dimensions may not be precisely met due to differing size designation approaches across platforms. For fixed-size outputs such as featured images, it is advisable to generate images with a similar aspect ratio and then adjust them to the final required dimensions. This approach aims to assist users who encounter similar challenges with image size adjustments. AI

IMPACT Users of AI image generation tools should be aware that precise pixel dimensions may require post-generation adjustments due to platform-specific handling of size specifications.

    Investigated why images generated by generative AI are not output at the specified pixel count. Because the concept of size specification differs among ChatGPT, Midjourney, Stable Diffusion, Gemini, etc., it seems best to assume "generate at a similar ratio and adjust at the end" for eye-catch images with a fixed final size. Similarly, for images
