Put it into practice
- Begin with an upright frame.
- Add a slight rotation and compare the same crop.
- Check corner clearance and text at delivery size.
What this looks like
A modestly tilted phone adds energy while a pricing table stays upright for comparison.
A detail to keep clear
Do not use dramatic perspective when the content must be read precisely.
Using MockupX
The editor separates output size from mockup type and layout. After changing a ratio, review every device, crop and text block. These are design decisions rather than automatic guarantees: a layout that works for a wide hero often needs a simpler arrangement on a portrait canvas.
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.
