# Three-size delivery checklist

- [ ] Create exactly three named outputs: 320, 800 and 1600 maximum-edge targets.
- [ ] Preserve aspect ratio; do not promise a square or exact edge when the source is not square.
- [ ] Open each saved file and record its actual dimensions.
- [ ] Count the saved files and compare with the required count.
- [ ] Check the destination's size, format and naming rules.
- [ ] Stop when a required size, count or destination rule is unknown.

These are synthetic examples and do not guarantee destination acceptance.
