Always design at 1080 px wide. For feed posts, portrait (4:5) gets the most screen real estate. Keep key content inside the safe zone for Stories and Reels — 250 px from both top and bottom.
TikTok Image Sizes
| Format | Dimensions | Aspect Ratio | File Size | Notes | Simulator |
|---|---|---|---|---|---|
| Video | 1080 × 1920 px | 9:16 | max 4 GB | Safe zone: top 130 px / bottom 220 px | Open Simulator |
| Profile Picture | 200 × 200 px | 1:1 | — | Displayed as a circle | — |
Keep all essential visuals between 130 px from the top and 220 px from the bottom — TikTok overlays its UI buttons in those zones.

LinkedIn crops feed images to ~1.91:1 in the feed preview. Design for the 1200 × 627 px ratio to avoid unwanted cropping when users don't click to expand.

The 2:3 portrait ratio (1000 × 1500 px) consistently outperforms square and landscape Pins. Avoid excessively long Pins — Pinterest may truncate them.
