In short
Use channel-specific dimensions and crop intentionally to avoid unwanted trims in feed and stories.
The correct approach is to export separate assets per placement (feed, story, reel cover) instead of reusing one image size for all Instagram contexts.
Why this works
- Each placement has different framing behavior and UI overlays.
- Placement-specific exports reduce accidental crops and hidden text.
- Targeted dimensions improve perceived quality on mobile.
When to use this workflow
- Your posts look cropped unexpectedly in feed previews.
- You prepare social content for multiple placements.
- You need a repeatable sizing workflow for a content team.
Step-by-step guide
- Decide target placement first: feed post, story, or reel cover.
- Resize to the target dimension before adding final crop refinements.
- Use a safe area mindset to protect text and logos from UI overlays.
- Export with balanced compression to keep detail while reducing size.
- Preview once on mobile before bulk publishing.
Common mistakes to avoid
- Designing only for desktop preview.
- Adding essential text near edges that UI can hide.
- Exporting oversized files with no visible quality gain.
Frequently asked questions
Can I use one size for every Instagram format?
You can, but it usually reduces visual quality and framing. Format-specific exports perform better.
