Instagram, YouTube & TikTok sizes explained
Platforms crop and scale aggressively. Exporting at the right size avoids blurry edges and cut-off faces. ConvertFlow includes these presets in the Image tab.
| Platform / use | Size (px) | Aspect |
|---|---|---|
| Instagram Post | 1080 × 1080 | 1:1 |
| Instagram Story / Reels | 1080 × 1920 | 9:16 |
| Instagram Portrait | 1080 × 1350 | 4:5 |
| YouTube Thumbnail | 1280 × 720 | 16:9 |
| YouTube Banner | 2560 × 1440 | 16:9 |
| YouTube Shorts / TikTok | 1080 × 1920 | 9:16 |
Tips
- Keep important content in the center — Stories and Reels hide edges under UI.
- For thumbnails, high contrast and large text work better than fine detail.
- Export JPG for photos or WebP for smaller files with similar quality.
- Use “Keep aspect ratio” or Contain + black fill so logos are not stretched.
Default fill color in ConvertFlow is black so letterboxed images look natural on dark UIs.
