Is there a way to make sure the image created is filled out to 100% of the width?

I ask Dall-e And Coloring Book Hero to make sure the aspect ratio is 1792x1024 or Wide, or in Landscape. But it just creates an images that are like 80% of the actual width, and put white, or some crayons or something similar on the edges...

No fail proof solutions but I've used following tricks with a measure of success: 1) giving a reason to make it wide, eg, "expansive landscape in the background." 2) add "A render of [what you want to make]" at the beginning of the prompt, 3) avoid using words like "coloring" "using pencils", etc. in the prompt.

Thanks @light folio I'll try that!

additionally you can tell it not to generate images with boarders this helps

Try using 16:9 landscape ratio and see how that goes. It has worked well for me (although this was from my own colouring book requests before custom GPTs)

I am having the same issue. All images are done in 1:1 aspect ratio. Why is this so difficult when one can just set the sizes or aspect ratios in Midjurney and get what they want. No having to coax.
