Understand device frame size versus export size

Put it into practice

1. Choose the output dimensions for the destination.
2. Place a compatible device inside that canvas.
3. Check the final file dimensions after export.

What this looks like

A detail to keep clear

A device label does not automatically satisfy an app store's screenshot specification.

Using MockupX

Device frames, output dimensions and source screenshot dimensions are separate choices. A phone frame on a square canvas is useful for social sharing; it is not automatically an accepted app-store upload. Check orientation, fit and output pixels independently.

Check the result

Keep the original screenshot, then review the exported file at the size where people will see it. Check the message, the visible interface and the final crop separately. For a handoff, record the destination and the approved file so another person can distinguish the final version from a draft.

References and further reading

Use the official references for format behavior and current destination requirements. The composition advice above is a practical design approach, not a promise of platform approval.
