Have these ready
Get the final landscape frame and mark where the person should sit. Keep the uncropped vertical original.
Expand the composition
Expand sideways when the subject already fits vertically. Start with a modest width increase so the new surroundings have fewer lines and objects to invent.
You choose your own source and review the current cost before generation.

Follow the horizon and wall lines across the join. A smooth color transition is not enough if the perspective bends at the original edge.
Mock up the destination frame before expanding. Place the original in the center, then decide which side needs extra room. Preserve the original face area and inspect the new edge at full size after the wider result is ready.
Expand my photo ↗Get the final landscape frame and mark where the person should sit. Keep the uncropped vertical original.
Place the source in the expansion canvas and add only the side space needed by the layout. Review the preview before submitting. Afterward, inspect the shoulder boundary, floor or horizon continuation and any repeated background object near the joins.
Expand when a good portrait needs breathing room. Crop when the source already contains enough background and the subject remains complete.

Why consider this directionUse the source to locate the existing subject and decide where extra layout space is actually needed.
Check before choosingCheck the original crop before interpreting any added area. Space outside it is not a photographed record of the surroundings.

Why consider this directionThe earlier wider example shows how extra surroundings can make room for a portrait-led layout.
Check before choosingFollow the joins near the shoulders and any straight background lines. Check the new composition with real text, not just the image alone.
They are generated continuation, not recovered photography. If the environment itself is evidence, use a real wider photograph. For an introduction layout, inspect the extension for plausibility and avoid treating invented furniture or signage as fact.
