You can use "wide angle" camera angle or add phrases like "zoom out" and "from a distance" to your prompts, but my original suggestion stands. If all else fails, use generative fill to expand the image.
@William26209755e5al, One work around might be to use the generative extend in Generative Fill (or in Photoshop). It seems to be pretty hard to get white space around an image in Text to Image. You can try: wide angle, zoomed out, distant view, etc, but they seem to have limited impact.
