Detailed result requirements

Required inputs

1 full-body photo + 1 change you want to preview

Input quality

The whole body posture is clear and the target parts are completely visible; shoulders, waist, hips, legs, etc. must be in the frame according to the adjusted parameters.

Composition

No universal public standard is available. Check the requirements of the platform or service you will use.

Output aspect ratio

Set the output canvas from the selected platform placement or production template, not from a reference image. Choose the option that matches this request: Body shape change preview working canvas — 2:3 (recommended). Use a different ratio only when a verified placement or production template requires it. If the platform does not require a fixed aspect ratio, use 2:3 as the recommended working canvas for body shape change preview. Compose the subject with appropriate breathing room. Create one aspect-ratio-specific deliverable per request; generate each additional placement as a separate output. Recompose for the selected ratio while preserving the complete subject, all text, and every required safe area. Never stretch the subject or treat cropping important content as adaptation.

What stays unchanged

No universal public standard is available. Check the requirements of the platform or service you will use.

Parameters such as arms, waist, abdomen, chest, hips, legs, shoulders, overall curve and height.

Background and setting
