When I setup Firefly to produce an image at 16:9 proportions, it produces the image at about 16.142:9. In other words, an image that should have been 1920x1080 comes out at 1937X1080. it takes extra time to crop the image to the correct proportions

Hi,

In Adobe Firefly, slight deviations from exact ratios (like 1937×1080 instead of 1920×1080) happen because the AI generates images using internal resolution steps rather than fixed pixel dimensions. This means the output is visually close to 16:9 but not mathematically exact. Unfortunately, there’s currently no setting to force perfectly precise dimensions at generation time. The most efficient solution is to apply an automatic crop in PS or resize preset to standardize your images quickly.
