Help getting full body in landscape aspect ratios?

Is there any reliable means of getting full-body imagry in a landscape aspect ratio? It seems to be an issue no matter what checkpoint you use. (I'm on sdxl 1.0)

I've tried with this (or variations) in the prompt:

Full body portrait, head-to-toe view, subject standing naturally, centered in the frame, captured from a low-to-mid angle to show the entire figure. High-resolution, sharp focus, realistic proportions.

And negative prompt:

cropped legs, cropped feet, missing legs, missing feet, cut off legs, cut off feet, out of frame legs, out of frame feet, partially visible legs, partially visible feet, truncated legs, truncated feet,bad framing, poor composition, too close, tight crop

I've also tried giving certain words/phrases more weight and saying things like "wide shot".

Is there a secret I don't know about?

Thanks!
