-
Start Large
- Create at highest resolution needed
- Usually 2000+ pixels on longest side
-
Use Safe Zones
- Keep important elements away from edges
- Different crops won't cut off content
-
Consider Aspect Ratios
- Design for 1:1 allows cropping to 4:5 or 16:9
- Center key elements for flexibility
Platform-Specific Strategies
For Instagram Grid + Stories
- Create vertical collage (1080 x 1350)
- Portion works in Stories
- Full image works in feed
For Facebook + Twitter
- Create 1600 x 900 landscape
- Works for both feeds
- Text remains readable
