Why correct sizing matters:
- Prevents cropping of key visuals and text.
- Maintains quality across feeds and tabs.
- Improves user experience and engagement rates.

For optimal clarity and display quality, follow Instagram’s recommendations:

This fills the smartphone screen seamlessly.

Safe Zones for Text and Graphics
UI elements (likes, comments, profile info) overlay your content. Respect safe zones:
- Keep text and graphics vertically centered.
- Avoid placing critical elements within 250 px of top or bottom.
- Use editor guides to frame content properly.

Tips for Shooting and Editing at Correct Dimensions
When shooting:
- Hold device vertically.
- Use cinematic mode or high resolution.
- Frame subjects for 9:16 composition.
When editing:
