Common mistakes

Avoid these snapchat story ad vs instagram story ad problems

Starting without the destination

Confirm whether the final output is print, upload, screen, or a template.

Ignoring aspect ratio

A size mismatch creates crop, padding, or distortion at export.

Skipping the source check

Confirm sources, limits, and output settings before sending the file onward.

Tools

Resize workflow

Open both source pages before exporting. If the aspect ratios differ, rebuild text and safe-area placement instead of only scaling the same artwork.
